WAITING FOR A PATTERN IN COIN TOSSING

ABSTRACT
Two commonly held misconceptions regarding a sequence of tosses of a fair coin are addressed. Thereasons for the misconceptions are discussed, and the correct analysis is provided. The results aresomewhat surprising to most people. The mathematical derivation of the correct results is followed by adiscussion of why our intuition may have initially misled us. Suggestions for various generalizations of theproblem follow.
KEYWORDS: Probability, conditional expectation, waiting times.
Mathematics Subject Classification: 60C05, 65C50.
1. INTRODUCTION
The Problem:
Consider a sequence of independent tosses of a fair coin. Suppose we are waiting for a certain pattern tooccur for the first time, say HHTT. We invite the reader to consider the following two questions, andguess the answers before reading on.
Q1: Which pattern requires a longer expected time to occur: or ?HH THQ2: Which pattern has a higher probability of occurring first: or ?HHH THH
Many, if not most people answer the questions as follows:
A1: "The expected times are the same for each pattern." A2: "Each pattern has an equal chance of occurring first."
How many readers answered this way? This certainly seems reasonable, since we have assumed the coin isfair. Unfortunately, as we propose to show in this note, . We will prove this byboth answers are incorrectexplicitly computing the relevant expectations and probabilities.
2. NOTATION AND PRELIMINARIES
We use standard notation, where denotes the probability that event occurs. denotes theTÐEÑ E TÐElFÑprobability that event occurs, given that event has occurred.

The latter proposition gives the mean of the geometric distribution. In particular, when tossing a fair coin,the expected number of tosses required to observe heads is 2.

5. INTUITION ADJUSTMENT
When faced with a counterintuitive result, most of us scrutinize what went wrong with our intuition, andtry to improve it. We offer the following scenario as an aid to "intuition adjustment".
Suppose we are to observe independent tosses of a fair coin and are to be awarded a large sum of moneywhen the pattern first occurs. When the first heads occurs, our pulse quickens. Suppose alas, that theHHnext toss is tails. We are discouraged, for now we must start from scratch. On the other hand, suppose weare to be awarded a large sum of money when the pattern first occurs. When the first tails appears, ourTHpulse quickens, but suppose, alas, that the next toss is tails. We are disappointed, of course, but things arenot so bad. We need not start from scratch, in fact we may win on the very next toss.
In view of these considerations, perhaps the results we have derived in this note do not seem so surprising.Yet, the heuristic argument above is of no help in actually computing the expected time for a pattern tooccur, or in computing the probability that one pattern precedes another.
6. GENERALIZATIONS
Many generalizations to the questions addressed in this note suggest themselves. In the first place, the coinmight be biased where the probability of getting heads on a single toss is and the probability of tails isß :ß; œ " :Þ Actually this does not present any substantial difficulty if the length of the patterns involved isrelatively small, say two or three as considered above. The reader is encouraged to work out the answersto Q1 and Q2 for a biased coin. A far more serious drawback to the methods presented here comes aboutwhen we consider longer patterns, such as computing the expected time required to observe the patternHHHTHTHHH. 4
Andreoli
The reason is obvious if one recalls that to compute the expected time to , we needed to first deriveHHHthe expected time to . The amount of calculation for long patterns grows daunting in a hurry.HH
Then there is the issue of generalizing the results to an experiment where a single trial may result in 8 #possible outcomes, where outcome occurs with probability Imagine tossing a "ten sided biased coin"3 : Þ3for example, and trying to compute the expected time until some pattern of length 30 appears.
Fortunately, the problem has been solved in complete generality. The interested reader may consult Ross[ , pp. 231-233] for one method of doing so. Ross uses the theory of Martingales in his analysis. While he2only works out two specific examples, these examples make it clear how to proceed to the general case,with only a modest amount of calculation. Ross uses a completely different method than the one used here,except as noted in section .3

COMMON MISTAKES MADE BY NATIVE SPANISH SPEAKERS

Campus, Miami, FL 33167, USA. Email: [email protected]
ABSTRACT
Language errors are quite common in any language, so it shouldn't come as a surprise
that native speakers of Spanish would make mistakes when speaking their language, and
although they generally aren't the same mistakes that are likely to arise in English, they
are probably as common. This paper presents a sample of some of the most common
errors made by native speakers of Spanish. Such mistakes are addressed in the courses
SPN2340 and SPN2341 [Spanish for Native Speakers I and II] at Miami Dade College.
Both courses also satisfy several of the Learning Outcomes of MDC, most notably #1
[Communicate effectively using listening, speaking, reading, and writing skills], and #5
[Demonstrate knowledge of diverse cultures, including global and historical
perspectives].
KEYWORDS
Spanish, lexical variations, common mistakes, spelling, grammar.
1. INTRODUCTION
Unless you're an incessant perfectionist for grammatical details, chances are you could
make dozens of errors each day in the way you speak. And you might not notice until
you're told that a sentence, or a word wrongly said, is enough to make some language
perfectionists grit their teeth.
Since language errors are so common in English, it shouldn't be surprising that
Spanish speakers often make their share of mistakes too when speaking their language.
Mistakes, particularly in grammar, are probably every bit as common in Spanish as they
are in English.
In many instances, there is no such thing as right or wrong when it comes to language,
only differences in how various word usages might be perceived. For example, there are
7
lexical variations noted in many standard Spanish words such as ‘piscina’ (swimming
pool), that in Mexico is referred to as ‘alberca’, but in Argentina is ‘pileta’, or ‘frijoles’
(beans) which in Venezuela are called ‘caraotas’, in Puerto Rico ‘habichuelas’, and in
Argentina ‘porotos’, and also ‘campesino’ (country person), which in Cuba is named
‘guajiro’, but in Chile is known as ‘huaso’, and in Puerto Rico ‘jíbaro’. There are also
cases in which one word may have different meanings, depending on the region where it
is used, as is the example of the slang word ‘guagua,’ which in the Caribbean is a bus,
but in the Andes region is a baby, or the verb ‘coger’ (to catch, to get), which in most
parts is used in its proper meaning, but in some other places carries a vulgar connotation.
I could go on and on citing many other similar examples, but that would be the topic for
another article. The point I wanted to bring across in presenting the few examples above
is that, although there is generally a standard lexicon used in all Spanish-speaking
countries, nonstandard varieties should not be dismissed as useless or undesirable
mistakes, but rather as different uses of the same word.
When it comes to grammar though, the situation is quite different because in this case,
it’s not a matter of simply dealing with lexical variety, but with mistakes regarded as
‘unacceptable’ by most educated people.
2. Most Common Errors Made by Spanish Speakers
Following is a list of some of the most common errors that Spanish speakers often
make; several of them are so common, they even have names to refer to them. Although
some speakers, especially in informal contexts, may find these mistakes acceptable, most
grammarians and language purists view them as uneducated or plain wrong. So then,
since there isn't unanimous agreement in all cases about what is to be considered correct
in language usage, some of the examples presented below will be referred to as
“improper” rather than as "incorrect".
Dequeísmo — In some areas, the use of de que in lieu of que has become so common,
that it is on the verge of being considered a regional variant, but in other areas it is
strongly looked down on as being the mark of an inadequate education.
Improper: No creo de que Pedro sea mentiroso.
Proper: No creo que Pedro sea mentiroso. (I don’t believe Pedro is a liar.)
8
Loísmo and laísmo — Le is the correct pronoun to use as the indirect object meaning
"to/for him" or " to/for her." However, lo is sometimes used for the male indirect object
pronoun, particularly in some parts of Latin America, and la for the female indirect object
pronoun, especially in certain parts of Spain.
Improper: La envié una carta. Lo escribí.
Proper: Le envié una carta (a ella). Le escribí (a él). (I sent her a letter. I wrote
to him.)
Leísmo — On the other hand, lo is the correct pronoun to use as the direct object
meaning “him.” However, le is sometimes used for the masculine direct object, although
mainly in Spain.
Improper: Le vi ayer.
Proper: Lo vi ayer. (I saw him yesterday)
Quesuismo — Cuyo is often the Spanish equivalent of the adjective "whose," but it is
used infrequently in speech. One quite popular alternative is the use of que su.
Improper: Conocí a una señora que su gato estaba muy enfermo.
Proper: Conocí a una señora cuyo gato estaba muy enfermo. (I met a lady
whose cat was very sick.)
Plural use of existential haber — In the present tense, there is practically no confusion
in the use of haber in a sentence such as "hay una silla" ("there is one chair") and "hay
tres sillas" ("there are three chairs"). In all other tenses, the rule is the same — the
singular conjugated form of haber is used for both singular and plural subjects. However,
in most of Latin America, and also in some parts of Spain, plural forms are often heard
and are sometimes simply considered as a regional variant.
Improper: Habían tres sillas.
Proper: Había tres sillas. (There were three chairs.)
9
Misuse of the gerund — The Spanish gerund (the verb form ending in -ando or -iendo,
generally the equivalent of the English verb form ending in "-ing") should generally be
used to refer to another verb, not to nouns as can be done in English. Yet, it appears to be
increasingly common to use gerunds to anchor adjectival phrases.
Improper: No conozco al hombre hablando con Teresa.
Proper: No conozco al hombre que habla con Teresa. (I don't know the man
speaking with Teresa.)
Errors in verb conjugation — There are numerous mistakes made when conjugating
verbs in different tenses. One of the most recurrent gaffes made in this category is the
addition of an the letter ‘s’ to the second person singular form (tú) of verbs in the preterit
tense, for example: hablastes instead of hablaste (you spoke); or the improper usage of
irregular verbs in either the preterit or the subjunctive, such as: conducí instead of
conduje (I drove), and indució instead of indujo (he/she induced), or haiga instead of
haya (there is/there are) and satisfazca instead of satisfaga (satisfy); last, but not least,
the common use nowadays of the non-standard past participle rompido instead of the
standard roto (broken).
Spelling mistakes — Since Spanish is a very phonetic language, it is normal to think that
mistakes in spelling should be unusual. However, while the pronunciation of most words
can almost always be deduced from their spelling (the main exceptions are words of
foreign origin), the reverse isn't always true. Native speakers frequently mix up the
identically pronounced b and v, or y and ll, for example, and occasionally add a silent h
where it doesn't belong or vice versa. It isn't unusual either for native speakers of Spanish
to be confused on the use of orthographic accents, that is, they may mistake aun (even)
with aún (still), el (the) with él (he), mas (but) with más (more), mi (my) with mí (me),
que (that) with qué (what), si (if) with sí (yes), solo (alone) with sólo (only), or tu (your)
with tú (you), which are pronounced identically.

3. CONCLUSION
SPN2340 and SPN2341, two courses offered at MDC specifically designed for native
speakers of Spanish, provide our considerably large population of bilingual students with
the opportunity, not only to learn about all the common mistakes presented above (and
many more), but to develop and improve their communicative skills [LO#1]. These
courses also expose students to the history, literature, films and current events of the
Hispanic world, thus expanding their cultural horizons and encouraging them to explore
other corners of the world in a different light [LO#5].

ABSTRACT
This paper demonstrates the importance and relevance of the PSC 1515 course for the
students pursuing an Associate in Arts Degree at Miami Dade College (MDC). This
course not only provides a general overview of the scientific method but also of the
different physical, natural and earth sciences. Of particular relevance is the study of
evolution, which is a recurrent controversial topic in our society because of the apparent
conflict between the scientific and religious points of view. In this paper, it is
demonstrated that this controversy is mostly limited only to the United States, although to
some degree, it is also expanding to the United Kingdom and other parts of Europe due to
the American influence in that part of the world. This course, PSC1515 also satisfies
several of the Learning Outcomes (LO) received by MDC’s graduates, particularly LO
#3, #6 and #10.
KEYWORDS
Evolution, creationism, intelligent design, science, religion, and scientific method.
INTRODUCTION
One of the most popular courses taken by Miami Dade College (MDC) students, as
part of the General Education Requirements for the Associate in Arts Degree, is PSC
1515 “Energy in the Natural Environment”. This course is included in the Natural
Science section, Group B – Physical Sciences of the General Education Requirements. In
the College Catalog, it appears in the Physics section, as one of the Physical Sciences
with a Multidisciplinary approach. The course description in the Catalog portrays it as an
“Investigation of the physical Environment using energy as a theme to demonstrate the
impact of science and technology on the environment and on the lives of people”.
This course satisfies several of the General Education Learning Outcomes (LO) that
demonstrate the knowledge acquired by MDC’s students, regardless of their major,
particularly Learning Outcomes #3, #6 & #10. Learning Outcome #3 establishes the
following: “As graduates of MDC, students will be able to solve problems using critical
and creative thinking and scientific reasoning”. This LO is approached since the first
12
chapter, in which the Scientific Method is discussed, and it is pursued throughout the
entire course content.
LO #10 establishes “how natural systems function and recognize the impact of
humans in the environment”. The goal of this LO is achieved throughout multiple
chapters in the course that discuss energy and its interrelationship with natural systems,
as well as the impact of human activities in the environment; special emphasis is placed
on global warming and its countless negative impacts in the environment and society,
ranging from the impacts on the ecosystems, health, the economy and –even- national
security.
The importance of LO #6 cannot be highlighted enough. This outcome “creates
strategies that can be used to fulfill personal, civic and social responsibilities”. The
issues that are discussed in the course, like evolution, global warming, and others will
help our students make informed decisions, as members of our society in many personal,
civic and social aspects, like voting for the appropriate candidate elections at different
levels, and also choosing the correct organizations to be involved with; and these are
decisions that reflect what is important, useful and necessary for the well-being of our
nation.
To fully understand the great importance of the depth of the scientific knowledge that
the learning of evolution provides to our students, we must consider the results of the
public opinion poll released by the Pew Forum on Religion and Public Life on August 30,
2005, which reveals that “nearly two thirds of Americans want both creationism… to be
taught along with evolution in public schools. Fewer than half of Americans – 48% -
accept any form of evolution… and just 26% accept Darwin’s theory of evolution by
means of natural selection. Fully 42% say that all living beings, including humans have
existed in their present form since the beginning of time” (cited by Jacoby, 2008).
According to Jacoby, 2008, this level of scientific unawareness cannot be blamed
solely on the low level of science education in American elementary and secondary
schools, as well as in many community colleges. In her book The Age of American
Unreason, Jacoby clearly states: “Only 27% of college graduates believe that living
beings have always existed in their present form, but 42% of Americans with only a
partial college education and half of high school graduates adhere to the creationist
viewpoint that organic life has remained unchanged throughout the ages. A third of
Americans mistakenly believe that there is substantial disagreement about evolution
among scientists – a conviction reinforcing and reflecting… that evolution is “just a
theory” (Jacoby, 2008).
The graduates of Miami Dade College who take the PSC1515 course, will not be
caught in the “just a theory” argument, because the first chapter of this course is
dedicated to the study of science and the scientific method, as well as the relationship
between science and religion. In this chapter, the students learn the scientific definition of
theory. To our students, a theory is ‘a synthesis of a large body of information that
encompasses well-tested hypotheses about certain aspects of the natural world’. Thus,
13
after taking the PSC1515 course, students of Miami Dade College become part of a
considerable percentage of college-educated Americans who will be thoroughly informed
about this transcendental scientific theory.
1. CREATIONISM
Advocates of the opposition to the study of evolution have attempted to substitute the
study of this theory, with the study of the afore cited theory of creationism, which can be
briefly defined as the religious belief that human life, the Earth and the Universe were
created in some form by a supernatural being, a God. For the Christian religion,
creationism is usually based on a literal interpretation of the book of Genesis in the Bible.
2. INTELLIGENT DESIGN
The concept of intelligent design was developed by a group of American creationists
who reformulated their argument in the creation-evolution controversy to evade court
rulings that ban the teaching of creationism as science. Intelligent design is the allegation
that some features of the universe (and of living things) are best explained by an
intelligent cause, not an undirected process such as natural selection. It is a more
contemporary form of the conventional teleological argument for the existence of God,
but without specifying the nature or identity of the ‘designer’, or creator. The discussion
about intelligent design must start by indicating that most of the scientific community has
rejected this idea. The U.S. National Academy of Sciences, the U.S. National Science
Teachers Association, and the American Association for the Advancement of Sciences
have all denounced intelligent design as a pseudoscience, because it is not testable
according to the principles and methods of science.
In a statement adopted on July 2003 by the Board of Directors of the National Science
Teachers Association, we can read: “The National Science Teachers Association (NSTA)
strongly supports the position that evolution is a major unifying concept in science and
should be included in the K-12 science education frameworks and curricula.
Furthermore, if evolution is not taught, students will not achieve the level of scientific
literacy they need”.
3. EVOLUTION
In his book, Richard Dawkins states: “all except the woefully uninformed are forced
to accept the fact of evolution”, adding to his statement that “…no reputable scientist
disputes it [evolution]” (Dawkins, 2009).
The National Academy of Science (NAS) and the Institute of Medicine (IOM)
released Science, Evolution and Creationism in 2008, where the importance of the
teaching of evolution in the science classroom was emphasized, or as the President of the
National Academy of Science, Ralph Cicerone, states: “The study of evolution remains
one of the most active, robust, and useful fields in science” (Cicerone, NAS, 2008).
14
The President of the Institute of Medicine, Dr. Harvey Fineberg, says: “Understanding
evolution is essential to identifying and treating disease. For example, the SARS virus
evolved from an ancestor virus that was discovered by DNA sequencing. Learning about
SARS’ genetic similarities and mutations has helped scientists understand how the virus
evolved. This kind of knowledge can help us anticipate and contain infections that emerge
in the future” (Fineberg, NAS, 2008). The same could even be said today about the
H1N1 virus causing the swine flu.
CONCLUSIONS
The importance of the study of PSC 1515 [Energy in the Natural Environment] is
such, that this class is at the basis of the scientific literacy acquired by the graduates of
Miami Dade College, and encompasses many of the Learning Outcomes that form the
core of a college education.
In PSC1515 students learn about science and the scientific method, and the basic
elements of evolutionary biology, in contrast to creationism and intelligent design. The
most important aspect of the study of evolution in this course is that our students are not
mandated to accept it or believe in it. They are given the elements of the three
approaches, and then are allowed to draw their own conclusions based on what they have
learned about the scientific method. The study of the chapter on evolution is
complemented with the study of the Universe and the Solar System, which includes the
theory of the Big Bang, the Nebular Theory and the evolution of the Universe and our
Solar System.
This class should be recommended to all MDC students, and the chapter on evolution
in particular must be considered of high relevance in the teaching of the course.

ABSTRACT
Multiobjective optimization is commonly used in every field where decisions are
made to determine optimal values for a given object or process. It’s been particularly
expanded in management and business and a wide variety of methods has been
developed. In this paper an original iterative algorithm is presented which takes into
account the difficulties for decision-maker to mathematically formalize priorities on the
functions vector.

1. INTRODUCTION
Multiobjective Optimization Problem (MOP) arises more often than we could think.
Optimization as it is understood in Mathematical Programming is reduced to the
maximization (minimization) of an Objective Function where the Domain of possible
solutions (alternatives) is given by a set of inequalities and equations. Defining one single
Objective Function is often too risky, since other parameters for the given system could
result with very undesirable values. The presence of multiple conflicting goals causes the
necessity of a new approach: Multiobjective Optimization. Different methods have been
developed: optimizing one single objective while on the other objectives constraints are
16
imposed; defining a global function as a combination of all objective functions; iterative
algorithms; and more recently evolutionary algorithms. Iterative algorithms are
particularly useful in situations where MOP regularly has to be solved and the task for
decision-maker to formalize the priorities on the functions vector becomes too hard and
eventually impossible. We show below some aspects of an original iterative algorithm
where optimization occurs after several runs of the mathematical model. On each step the
Domain is reduced to a subset within the set of Pareto-optimal solutions by following an
evaluation rule and eventually a single solution is obtained.
2. MULTIOBJECTIVE OPTIMIZATION
2.1 THE PROBLEM
Let’s define MOP as follows:
min,))(),...,(),((
21
xfxfxfF
m
(1)
x
where
m
is the number of Objective Functions, and the Domain
is given by
linear inequalities and equations defined on the variable
x
. A trivial solution is
obtained when the optimum occurs simultaneously for all functions. This rarely happens
in real-world problems.
2.2 THE SOLUTION
Basic Principles of the Algorithm
The algorithm is based on the following statements:
Let
III
pp
,
(
I
- the set of the Objective Functions) and let
ppb
i
IIIif \,
be given boundary values.
17
Let’s define preference relation
P
such that
xPy
if
,),()(
p
ii
Iiyfxf
(2)
and for at least one value
i
the inequality is strict and, in addition
pb
ii
Iifxf ,)(
(3)
Then the idea of narrowing the Pareto-Optimal Solutions set (
T
) can be executed
as follows. Let the point
y
is fixed and ‘’preferable’’ rather than any
z
according to decision-maker’s evaluation rule,
p
zTzz ,:
,
region
p
is defined by inequalities (2)-(3) .
In the region
p
T
is executed the optimization. This resembles the idea of
set of ‘’individuals’’ after selection process and prior to ‘’recombination’’ and
‘’mutation’’ in Evolutionary Algorithms [1],[5].
Given
p
I
and
y
, found after initial approximation, the optimization is carried out
according to the principle of minimum deviation from
p
i
Iiyf ),(
. As a rule
minimal deviation is not obtained simultaneously for all mentioned functions. Then
principle of best guaranteed value is applied, i.e. minmax principle.
Let functions

Let
s
w
be an intermediate solution (at iteration s ),
ss

18
At every iteration of the algorithm, the decision-maker redefines the preference
vector based on the obtained intermediate alternative.
s
I
is defined as the set of
functions to be submitted to ‘’improvement’’ on the given iteration.
Boundary values on the iteration (

then the auxiliary variables are ‘’0’’ and no correction is needed.
At iteration ‘’s’’ the MOP (4) becomes:

3. CONCLUSIONS
An algorithm for the solution of MOP has been presented. The algorithm consists of
an iterative process. At each iteration, according to an evaluation rule, the set of
26
alternatives is reduced to ‘’more preferable’’ points. Narrowing the searching Domain
serves the approximation to the ‘’ideal’’ alternative, a point that rarely in practice is
achieved. Some statements have been proved to show convergence of the algorithm and
Pareto-Optimal character of the solution. Decision-maker deals directly with objective
functions vector, which has considerably lower dimension rather than the Domain of
alternatives.

1. INTRODUCTION
The accomplishments of the past and present can serve as pathfinders to present and
future mathematicians. African- American mathematicians have contributed in both large
and small ways that has been overlooked when chronicling the history of science. By
describing the scientific history of selected African-American men and women within
mathematical sciences we can see how the efforts of individuals have advanced human
understanding in the world around us. The abilities and accomplishments of these Afro-
American scholars of science and mathematics cannot be underrated. History bears
testimony to their achievements. The purpose of this paper is to highlight and exhibit the
accomplishments of African-Americans within the Mathematical Sciences. The materials
presented are based on the “Mathematicians of the African Diaspora”,
(www.math.buffalo.edu/mad/index.html).
The organization of this paper is as follows. Section 2 contains a Tree Diagram of
African-Americans in the mathematical sciences by dividing it into four different periods,
beginning from 18th century to present. These periods have been further classified
indexed by year. In Section 3, a chronology of African-Americans in mathematical
sciences is presented. The statistics on the numbers of African-Americans receiving
Ph.D.’s in mathematics, during the period 1925 – 2004, have been presented in Section 4.
The achievements of African-Americans in the mathematical sciences are highlighted in
section 5. The concluding remarks are presented in Section 6.

The following is a Tree Diagram depicting the different periods of African-Americans in
Mathematical Sciences.
3. A CHRONOLOGY OF AFRICAN-AMERICANS IN MATHEMATICAL
SCIENCES
The following is a chronology of African-Americans in mathematical sciences.
3.1 AFRICAN-AMERICAN MATHEMATICIANS OF 18TH CENTURY
The names of the following African-Americans of 18th century are available through
historical records, who have contributed in the field of mathematical sciences:
(i) Muhammad ibn Muhammad (16?? - 1741)
(ii) Thomas Fuller (1710 - 1790)
(iii) Benjamin Banneker (1731 - 1806)
Development of African-American influence in mathematical sciences began with the
work of Benjamin Banneker, who used the method of doubling sequences to generate an
estimate for the method of false position. Benjamin Banneker is often recognized as the
first African American mathematician. However, the names of ex-slave Thomas Fuller
and the Nigerian Muhammad ibn Muhammad also appear in history, whose mathematical

activities predate Benjamin Banneker. It is interesting to note that none of these men had
formal degrees.
3.2 AFRICAN-AMERICAN MATHEMATICIANS OF 19TH CENTURY
Below is the list of three African-American mathematicians of 19th century, who are
prominent for their contribution to the knowledge and advancement of mathematical
sciences.
(i) Charles Reason (1814 - 1893) is considered to be the first African-American to
receive a faculty position in mathematics, in the year 1849, at a predominantly white
institution - Central College in Cortland County, New York.
(ii) Edward Alexander Bouchet was the first African-American to earn a Ph.D. in
Physics (Science), in the year 1878, from Yale University, and only the sixth American to
possess a Ph.D. in Physics. It should be noted that Yale University became the first
United States of America institution, in the year 1862, to award a Ph.D. in mathematics.
(iii) Kelly Miller was the first African American to study graduate mathematics, in the
year 1886, at Johns Hopkins University. It will be interesting to note that Johns Hopkins
University was the first American University to offer a program in graduate mathematics.
3.3 AFRICAN-AMERICAN MATHEMATICIANS OF 20TH CENTURY
The list of African-American mathematicians of 20th century is very exhaustive. In the
following paragraph, a chronology of African-Americans, who have excelled and
contributed to the knowledge and advancement of mathematical sciences, during the
period 1900 – 1999, is presented, (see, for example, the “Mathematicians of the African
Diaspora” website created and maintained by Professor Dr. Scott W. Williams, Professor
of Mathematics University at Buffalo, SUNY, among others).
(1) 1925: Elbert Frank Cox was the first African-American to earn a Ph.D. in
Mathematics in 1925 from Cornell University. There were 28 Ph.D.'s awarded in the
United States that year.
(2) 1928: Dudley Weldon Woodard was the second African-American to earn a Ph.D.
in Mathematics in 1928 from the University of Pennsylvania.
(4) 1933: William Schieffelin Claytor was the third African-American to earn a Ph.D.
in Mathematics (University of Pennsylvania). Dr. Claytor had an extraordinary promise
as a mathematician.
(5) 1934: Walter R. Talbot was the fourth African-American to earn a Ph.D. in
Mathematics (University of Pittsburgh).
30
(6) 1938: Ruben R. McDaniel (Cornell University), and Joesph Pierce (University of
Michigan) were the fifth and sixth African-Americans to earn a Ph.D. in Mathematics in
the year 1938.
(7) 1941: David Blackwell was the seventh African-American to earn a Ph.D. in
Mathematics, in the year 1941, from the University of Illinois. Dr. Blackwell earned his
Ph.D. at the age of 22. He is regarded as one of the greatest African-American
mathematician of the 20th century. Dr. Blackwell is famous and well-known in the world
of mathematics for his seminal “Rao-Blackwell Theorem” which gives a technique for
obtaining unbiased estimators with minimum variance with the help of sufficient
statistics (see, for example, Dudewicz and Mishra (1988), Kapur (1999), and Rohatgi and
Saleh (2001), among others). In 1954, Dr. David Blackwell became the first African-
American to hold a permanent position at one the major universities, University of
California at Berkley.
(8) 1942: J. Ernest Wilkins became the eighth African-American to earn a Ph.D. in
Mathematics, in the year 1942, from the University of Chicago. Dr. Wilkins earned his
Ph.D. at the age of 19. He is also regarded as one of the greatest and rarest African-
American mathematician of the 20th century
(9) 1943: Euphemia Lofton Haynes (Catholic University), the first African -American
woman, and Clarence F. Stephens (University of Michigan) were the ninth and tenth
African-Americans, respectively, to earn a Ph.D. in Mathematics (see, for example, the
websites “Black Women in Mathematics” and “Timeline of African American Ph.D.'s in
Mathematics,” among others). The Morgan-Potsdam Model is the name given to a
method of the teaching of mathematics developed by Dr. Clarence F. Stephens at Morgan
State University and refined at the State University of New York College at Potsdam. Dr.
Clarence F. Stephens also received the Mathematical Association of America Gung-Hu
Award for the Pottsdam Miracle. Under the direction of Dr. Clarence Stephens, Morgan
State University became the first institution to have three African-Americans of the same
graduating class (1964), who obtained a Ph.D. in Mathematics. These people were Dr.
Earl Barnes (University of Maryland, 1968), Dr. Arthur Grainger (University of
Maryland, 1972), and Dr. Scott Williams (Lehigh University, 1969). This is still a record
that stands among all U.S. universities and colleges.
(10) 1944: This is the year when the eleventh, twelfth and thirteenth African- Americans,
Joseph J. Dennis (from Northwestern University), Wade Ellis, Sr. and Warren Hill
Brothers (both from University of Michigan), respectively, earned a Ph.D. in
Mathematics.
(11) 1945: Jeremiah Certaine was the fourteenth African-American to earn a Ph.D. in
Mathematics, in the year 1945, from the University of Michigan.
31
(12) 1949: Evelyn Boyd Granville was the fifteenth African-American and the second
African-American Woman to earn a Ph.D. in Mathematics, in the year 1949, from Yale
University.
(13) 1950: Marjorie Lee Browne (University of Michigan), the third African-American
Woman, and George H. Butcher (University of Pennsylvania) were the sixteenth and
seventeenth African-Americans, respectively, to earn a Ph.D. in Mathematics, in the year
1950.
(14) 1953: Luna I. Mishoe was the eighteenth African-American to earn a Ph.D. in
Mathematics from New York University.
(15) 1954: Charles Bell was the nineteenth African-American to earn a Ph.D. in
Mathematics from the University of Notre Dame.
(16) 1955: Vincent McRea (Catholic University) and Lonnie Cross (Cornell University)
were the twentieth and twenty-first African-Americans to earn a Ph.D. in Mathematics.
(17) 1956: Lloyd K. Williams (University of California at Berkeley) and Henry M.
Elridge (University of Pittsburgh) were the twenty-second and twenty-third African-
Americans to earn a Ph.D. in Mathematics in the year 1956.
(18) 1957: Eugene A. Graham, Jr. (University of Turin in Italy) and Elgy S. Johnson

4. STATISTICS OF AFRICAN-AMERICAN Ph.D.’s IN
MATHEMATICAL SCIENCES (1925 – 2004)
According to the list as presented in Section 3 above, it is interesting to note that a
total of 392 African-Americans had received a Ph.D. in mathematics during the period
1925 – 2004. For the sake of our statistical computations, we have divided this period
into four different sub-periods: 1925 – 1944, 1945 – 1964, 1965 – 1984, and 1985 –
2004. Out of 392 African-American Ph.D.’s in mathematics, 3.32 % received their
Ph.D.’s during the period 1925 – 1944, 8.42 % received their Ph.D.’s during the period
1945 – 1964, 40.05 % received their Ph.D.’s during the period 1965 – 1984, and 48.21 %
received their Ph.D.’s during the period 1985 – 2004. From the analysis presented here, it
is easily seen that the maximum number of African-Americans receiving Ph.D.’s in
mathematics was during the period 1985 – 2004. The statistics on the numbers of
African-Americans receiving Ph.D.’s in mathematics, during the period 1925 – 2004,
have been presented inthe Figure 4.1 below.

ABSTRACT
In recent years, there has been a great interest in the problems of grammar and
mechanics instruction to the freshman English. In this paper, the students’ familiarity
with grammar and mechanics of English language has been studied from an exploratory
point of view. By administering a survey on the grammar and mechanics in some classes,
the data have been analyzed statistically which shows some interesting results. It is hoped
that the findings of the paper will be useful for researchers in various disciplines.
KEYWORDS
ANOVA, grammar, hypothesis testing, mechanics, prescriptivist approach, Shannon’s
diversity index.
1. INTRODUCTION
As noted by Teorey (2003), although the usage of prescriptivist approach to grammar
instruction was rejected by the linguistic community nearly one hundred years ago, its
importance in the present day instruction of English language cannot be overlooked. It
appears from the literature that not much work has been done on the problem of students’
familiarity with grammar and mechanics of the English language. Certain guessing
experiments to measure the predictability (defined in terms of entropy) of ordinary
literary English were devised by Shannon (1951). A study to determine the predictability
of English whether it is dependent on the number of preceding letters known to the
subject was conducted by Burton and Licklider (1955). The variations in the predicting
capacities of students learning English as a foreign language were studied by Siromoney
(1964). Recently, Joyce (2002) has studied the use of metawriting to learn grammar and
mechanics. Using freshman composition, the problems of grammatical errors and skills
have been studied by Teorey (2003). In this paper, we propose to study the students’
familiarity with grammar and mechanics of English language from an exploratory point
of view. The data have been analyzed statistically. The organization of this paper is as
44
follows. Section 2 discusses the methodology. The results are given in section 3. The
discussion and conclusion are provided in Section 4.
2. METHODOLOGY
A survey consisting of 20 multiple choice questions (see Appendix I) was constructed
to test students’ familiarity with English grammar and mechanics in six different courses
in the spring semester of 2009. The courses selected were ENC 0021, ENC 1101, ENC
1102, EAP 1640, MGF 1107 and MAC 2233. The survey was administered by the
instructors in each of these courses. A total of 121 students participated in the survey the
details of which are provided in the following Tables 1 and 2 below.

3.3 HYPOTHESIS TESTING: INFERENCES ABOUT TWO MEAN SCORES
This section discusses the hypothesis testing and draws inferences about the mean
46
scores of two independent samples. Following the procedure on pages 474-475 in Triola
(2010) of not equal variances: no pool, the hypothesis testing was conducted for three
sets of two independent groups by using the statistical software package STATDISK. The
results of these tests of hypotheses are provided below.
(I) INFERENCES ABOUT MEAN SCORES OF ENC AND MAT PARTICIPANTS
For this analysis, we defined the two groups as follows:
ENC/EAP: ENC 0021, ENC 1101, ENC 1102, EAP 1640
MAT: MGF 1107, MAC 2233
The descriptive statistic of ENC/EAP and MAT participants is given in Table 4 below.

3.4 ANALYSIS OF VARIANCE (ANOVA) AND DIVERSITY ANALYSIS
This section discusses the analysis of variance for testing the hypothesis of equality of
the mean scores and diversity analysis for testing the hypothesis of evenness ratio of
respondent performance based on gender-language spoken. All these analyses were
carried out by using the statistical software packages STATDISK and EXCEL.
(I) Respondent Performance Based on Gender-Language Spoken
The performance of respondent based on gender-language spoken is provided in Table 10
and Figure 8 below.

Following the procedure on pages 628-631 in Triola (2010), this section discusses the
ANOVA for testing the hypothesis of equality of the mean scores of four independent
groups based on gender-language spoken, that is, AA, AB, BA, and BB. The results of
ANOVA are provided in Table 11 and Figure 9 below. (Note: There was only one female
who spoke French and so was included in group BB for analysis purposes.)

(III) Diversity Analysis
Applying the Shannon’s Measure of Diversity Index (in terms of entropy) (Shannon,
1948), this section discusses the diversity analysis for testing the hypothesis of evenness
ratio of respondent performance based on gender-language spoken, that is, AA, AB, BA,
BB, and BC. The results of Diversity Analysis are provided in Table 12 below.

Hypothesis: Does the respondent performance (that is, proportion of students scoring 60
or above based on gender-language spoken, that is, AA, AB, BA, BB, and BC, as
provided in Table 12 above) suggest more diversity in the groups’ familiarity with the
English grammar and mechanics?

4. CONCLUSIONS
This paper discussed the students’ familiarity with grammar and mechanics of English
language from an exploratory point of view. A total of 121 students from six different
courses, that is, ENC 0021, ENC 1101, ENC 1102, EAP 1640, MGF 1107 and MAC
2233, participated in the survey. The minimum % to pass was 60. Out of 121 survey
participants, 90.10 % scored 60 or above. Based on the hypothesis testing, the following
inferences were drawn about the survey participants.
1. There was sufficient evidence to support the claim that the mean scores of Male
and Female participants were same.
2. There was sufficient evidence to support the claim that the mean scores of
ENC/EAP and MAT participants were same.
3. There was sufficient evidence to reject the claim that the mean scores of
Native English speaking and Non-native English speaking participants were
same.
4. There was sufficient evidence to reject the claim of the equality of mean scores of
four independent groups based on gender-language spoken, that is, AA, AB, BA,
and BB.
5. There appears to be complete evenness in the respondent performance (that is,
proportion of students scoring 60 or above based on gender-language spoken).
53
It is hoped that the findings of the paper will be useful for researchers in various
disciplines.
ACKNOWLEDGMENT

ABSTRACT
The writing strategies students use most often in preparing for the subjective and
objective tests of writing for College Preparatory Writing 3 were examined. To address
this, data was collected using a comprehensive survey that asked students about the
strategies they used in four different domains: vocabulary strategies, comprehension
strategies, grammar strategies, and strategies to specifically improve writing skills. It was
hypothesized that students’ use of writing strategies on the exit exam resulted in a
substantial percentage of students retaking the course. The results indicated that the
percentage of students using different strategies varied dramatically. Some strategies
were used very frequently while others were not.

1. INTRODUCTION
In the 1970s and 1980s, a high school diploma guaranteed high-paying jobs, however,
given today's career markets and job competition, a college education has become
essential and necessary. Obtaining a college degree is valued and beneficial to the
potential college graduate (National Center for Education Statistics [NCES], 2003).
Students entering colleges or universities are expected to bring prior knowledge and
experiences learned at the high school level as a foundation for college study. Basic skills
in English, mathematics, reading, and writing are the underlying groundwork essentials
for a productive college experience and completion (NCES, 2003). These skills are then
57
further developed through a series of courses taken at the college or university level for
the purpose of obtaining a certificate or a degree. The harsh reality is that a majority of
students entering colleges and universities do not have the basic principles associated
with becoming a college student, and as a result require special interventions in the form
of developmental or remedial courses (Carter, Roth, Crans, Ariet, & Resnick, 2001).
In 1996, NCES revealed that 77% of higher education institutions in the nation with
an enrollment of freshmen offered at least one remedial reading, writing, or mathematics
course in fall of 1995. Similarly, the same research was conducted in 2000 and reported
in 2004. The research revealed that 76% of the higher education institutions still offered
at least one remedial reading, writing, or mathematics course in the fall of 2000. The
difference in the 1% drop in a four-year period is insignificant in relation to the number
of underprepared students currently entering colleges and universities nationwide (NCES,
2004).
Further, the Florida Department of Education (2007) reported in 1999 that 59% of
high school students entering the community college system require remediation in one
or more areas. The need for remediation is prevalent among community colleges and
while the exact percentages are not known, slightly 37% of entering college freshmen
needed at least one area of remediation. The presence of developmental programs in 94%
of public colleges and 82% of private colleges in Florida reflect the present continuing
need (Wyatt, 1992).
For one particular college in South Florida, 81% of students enrolled are
underprepared according to scores analyzed on the Computerized Placement Test (CPT)
(Bashford & Mannchen, 2005; Rodriguez, 2006). Since 1985, the State of Florida has
58
required entry-level testing for students seeking Associate in Arts and Associate in
Science degrees. In 2006 the College Academic Student Support Council stated “The
CPT is used for placement at all Florida community colleges for most programs” (p. 4).
Therefore, every degree-seeking student at the college must take the CPT. The College
Academic Student Support Council also stated the CPT is the test that determines how
college-ready the students are since it “assesses students' content knowledge in reading,
sentence skills, and mathematics” (p. 4). Since the CPT is an adaptive test, the computer
automatically determines which questions are presented to the students based on their
responses to prior questions. This technique zeroes-in on just the right questions to ask
without being too easy or too difficult. Consequently, Morris (2006) stated “The greater
the students demonstrate skill level, the more challenging will be the questions
presented” (p. 2).
Students who take any of the three levels of remedial writing should be prepared to
move to the next level, which is ENC1101 or regular freshman English Composition 1.
However, according to the subject college's records, the Research and Testing Committee
revealed that the progression of students from college preparatory writing to college level
English has declined for the past three years and is now 48% (Morris, 2006). Upon
learning this, the researcher set out to discover possible reasons why the decline was
consistent for three years. A set of 28 writing strategies where examined with the
sampled student population to identify a possible correlation between students’ frequent
use of strategies and their passing rate on the exit test.

2. RESEARCH QUESTIONS AND METHODOLOGY
RESEARCH QUESTIONS
Based on the concern that students may not be applying the proper strategies to
successfully pass the Florida College Basic Skills Exit Test, four research questions were
analyzed. Therefore, for the purpose of this study the researcher investigated strategies
used by the ENC0021 student population that could be predictors of the decline in
enrollment from ENC0021 to ENC1101. The purpose of this study was multifold and the
following research questions were addressed:
1. What are the most common writing strategies that students employ?
2. Is there a relationship between the use of different strategies? That is, do students who
frequently use one type of strategy (e.g., vocabulary) also use other strategies (e.g.,
grammar) with high frequency?
3. What are student’s perceptions of the Florida College Basic Skills Exit Test and the
content of its essay prompts?
4. Do writing professors think students feel writing has value in high school and college
courses, in overall academic performance, and in their future?
Research has indicated possible reasons as to why students enter college
underprepared. According to Hoyt and Sorensen (2001) the most popular trend in
education today is the “chain of blame” game. This “chain of blame” occurs when
“universities blame the high schools, the high schools blame the middle schools, and the
middle schools blame the elementary schools for poor student preparation” (p. 26). In
essence, the lack of preparation at the secondary level has become a hindrance for
students who wish to pursue a college education.
60
Furthermore, in a recent study of high school preparation and placement testing, Hoyt
and Sorensen found that as part of the standards movement, including their home state of
Utah, certain states are “implementing mandatory proficiency tests, releasing report cards
on schools,” and “differentiating high school diplomas, giving some students credit for
demonstrating competence in college preparatory courses based on proficiency exams”
(p. 32). A similar approach has also taken effect in Florida schools in regard to the
FCAT. Hoyt and Sorensen also discovered that teachers “may be awarding passing
grades to many students who have not adequately learned the material” (p. 32). This
scenario jeopardizes those students whose intentions are to attend college.
In addition, Hidi and Harackiewicz (2000) stated that another possible reason for the
underpreparedness of secondary students is the lack of motivation and effort. Hidi and
Harachiewicz affirmed that boring courses, demanding professors, and difficult
assignments all contributed to the college students’ lack of effort. However, the research
did not indicate as to when the underpreparedness occurred. There is clearly a need for
more structured readiness at the secondary level so that students will be well-prepared
prior to entering college, but research still indicates that a need for remediation at the
college level will continue to be prevalent today and in years to come (Hoyt & Sorensen,
2001; Wyatt, 1992).
Colleges and universities have a responsibility to maintain appropriate admission
standards. But the admissions process at open institutions, give underprepared students a
second chance at a college education, and should be structured to ensure that students are
prepared for college level course work (Hoyt & Sorensen, 2001).
61
The progression of students from College Preparatory Writing 3 to English
Composition 1 (ENC0021-ENC1101) respectively, has declined for the past three years
(Morris, 2005). In ENC0021 two state-mandated tests are to be taken and passed before
students are allowed to register for ENC1101. This study focused on tracking the number
of students who move from ENC0021 to ENC1101.
In another study of student preparation, Thot-Johnson and Vanniarajan (2002)
focused on students reading and writing strategies and high-stakes performance. Their
study indicated that students used writing strategies that they believed were useful
strategies. Thot-Johnson and Vanniarajan noted that students “would feel empowered and
would be further motivated to use them, which subsequently would result in increased
skill execution” (p. 5).
The study also specified that students who do not internalized writing strategies
experience difficulty in becoming independent thinkers and writers. However, research
showed that students of writing who are underprepared worked twice as hard and wrote
twice as many drafts as their “prepared” counterparts, and were conscientious about their
progress (Community College Survey of Student Engagement, 2005; Crouch, 2000).
Writing abilities vary by individuals. Each one has a set of unique life experiences
developed, different experiences with strategies, and different ways of communicating.
When the final exam writing prompt was given to students, no two writers used the same
prewriting techniques in order to develop a cohesive essay, nor did the student writers
expressed the same point of view. This was due in part because students were taught to
write in different ways.
62
According to Carter, Roth, Crans, Ariet, and Resnick (2001) the explanation most
commonly given by community college officials for the high failure rate on the CPT is
that “students’ course-taking choices in high school did not equip them with the skills
needed to do college-level work” (p. 73).
Thus, the possibility of these studies might have attributed to the causes of the
educational trends, but one can never be sure. Is the relationship between the chain of
blame game and students’ lack of success on the CPT so obvious and so closely related
that one influences the outcome of the other? If so, ultimately where does the chain of
blame game begin or end?
There is a need for a collaborative effort between the local high schools and the local
community colleges and universities. Hoyt and Sorensen (2001) suggested that college
and university faculty should assist high school instructors in the process of developing
English and mathematics curriculum to better prepare students for subsequent college
level course work. Perhaps pre college students would benefit from their suggestions
since the subject college is a diverse college.
And although only 19% of all entering students are college-ready, the college
promises to help produce individuals of great success and fortitude. Finally, the
implementation for newly designed placement exams at the college level are still
unknown at this time, but there is evidence that new proposals are in the work and will be
available in the near future (Sanchez, 2006).
63
METHODOLOGY
This study focused on a population made up of 74 college preparatory students. The
74 students were enrolled in five courses of ENC0021. Students and professors were
selected based on a volunteer basis and availability of time. A questionnaire (Appendix
B) surveying the 74 students was distributed to collect data addressing the research
questions. An additional questionnaire (Appendix C) was distributed to the professors
that taught writing for the spring term 2008 with the idea of gaining a greater perspective
of the students enrolled in ENC0021 as well as the professors' teaching philosophy. A
total of eight full- time professors volunteered for the study.
The participants, to include students and professors, were made aware of the
significance of the study via a Letter to Professors (Appendix D) and a Letter to Survey
Recipients (Appendix E). The data determined students' attitude about writing and about
the Florida College Basic Skills Exit test for the sole purpose of aiding the researcher in
reporting the findings.
In order to have conducted such an investigation, the researcher chose an
experimental design approach to determine if there was a correlation between the Florida
College Basic Skills Exit test and students’ non-passing status from the developmental
level of writing courses to regular level college courses.
3. CONCLUSIONS
This study will contribute to the literature as the existing literature has not studied the
correlation between students’ use of writing strategies and the Florida College Basic
Skills Exit Test. This chapter will highlight the summary of survey results, summarize
exit exam results, summarize qualitative teacher surveys, discuss implications for
64
practitioners, integrate findings with the current study with previous studies, discuss
limitations, and offer recommendations.
One of the primary research questions of this study addressed the use of different
writing strategies. To address this, data was collected using a comprehensive survey that
asked students about the strategies that they used in four different domains: vocabulary
strategies, comprehension strategies, grammar strategies, and strategies to specifically
improve writing skills. The subsequent analysis results summarize the use of these four
broad writing strategies, each of which was addressed using a series of questionnaire
items. For each strategy, students were first asked whether they used the strategy. If they
reported using a strategy, a follow-up question asked whether the student used the
strategy “Some of the time” or “Most of the time”.
The percentage of students using different strategies varied dramatically. Some
strategies were used very frequently while others were not. Considering all four
categories (vocabulary strategies, comprehension strategies, grammar strategies, and
strategies to specifically improve writing skills), the survey addressed 28 unique
strategies. Table 13 summarizes the overall results by rank ordering the 28 strategies
according to the percentage of students that use each approach. As seen in the table, only
6 of the 28 strategies (21.4%) were used by more than 90% of the students. Among these
top strategies, four were vocabulary-related.
A larger tier of 10 strategies were used by 80% to 90% of the students. As seen in the
table, this set of strategies included a mix from the four categories. Finally, nearly half of
the strategies were used by fewer than 70% of the students. Among this set of
approaches, two strategies were used with very low frequency: observing classmates’
65
essays (55.6%) and giving up on what to say (46.6%). Giving up is a poor strategy, so it
is not a surprise that this approach was ranked last. However, nearly half of the sample
reported using this strategy. Obviously, this has an important bearing on students’ ability
to improve their reading and writing skills.

A separate set of analyses examined the impact of the Florida State Writing Exit Test
on course performance. Specifically, students were categorized according to whether they
had satisfactory performance in the class prior to taking the exam. Among the students
who were performing satisfactorily, 88.5% passed the exit exam. This means that 11.5%
of the students who were otherwise performing well had to repeat the course because they
failed the exit exam. Looking at these results differently, 29 students failed the exit exam.
Among these students, 24% had satisfactory performance prior to taking the exit exam.
This suggests that the exit exam does result in a substantial proportion of students
retaking the course.
67
An analysis of research question 3 revealed that professors believe their students
employ the capabilities of being successful at writing. The overall consensus was that one
view looks at writing as a process of filling in the blanks of a 5-paragrah formula that
doesn’t have much meaning beyond preparation for standardized exams. Another view
looks at writing as a genuine process of exploration and creative reflection that is part of
living their lives. However, the overall opinion was that some students’ view are
somewhere in the middle of the two extremes. And while many students understand the
more creative model, they do not see it as one that is valued in school, even though they
may apply it on their own. Although at diametric extremes in years of experience, the
overall philosophies were similar. The instructors interests were on behalf of their
students’ successes and capabilities in learning how to writing at the college level and to
become life-long learners.
In accordance with the outcome of table 13, the top six strategies students used with
most frequency are considered weak strategies. These strategies are not consistent with
approaches that will improve student performance. With the exception of paying attention
to how a word is being used in context, the overall results of the top six strategies are
ineffective according to the writing curriculum at the college level. Cleary, practitioners
need to be made aware of the types of strategies being used by the writing student
population in the classroom, since these same strategies are most likely the same ones
being implemented when students take the Florida College Basic Skills Exit Test.
The strategies used by 80% to 90% of the students are strategies that could be
considered helpful depending on the goals of each individual writing instructor. And
although instructor goals may vary, generally the ultimate outcome is for students to feel
68
comfortable with writing in a college setting. Therefore, instructors need to emphasize on
the strategies that are used by the larger population of students and not necessarily the
ones they use most frequently in the classroom. This finding also has important
implications for high school educators, counselors, and parents. High school students
should be advised as early as the ninth grade of college preparedness. One study revealed
that the more students that take the more difficult courses in high school consequently
score higher on standardized test, thus eliminating the need for remediation at the college
level. (Carter, Roth, Crans, Ariet, & Resnick, 2001)
On the whole, the implications of the results on instruction indicate that students use
writing strategies with high frequency at least 80% of the time. Students will use what
instructors teach them. If that is the case, it is obvious then that effective strategies need
to be taught. One reason to teach students these strategies is due in part because writing is
process based as opposed to content based. Instructors can only teach students how to
learn to write (Thot-Johnson & Vanniarajan, 2001).
It is important to integrate the results of this study with previous research studies.
Several studies had similar outcomes in regards to students’ frequent use of writing
strategies and performance on standardized testing.
Thot-Johnson and Vanniarajan's (2002) study revealed that by the time students enter
undergraduate studies they realize that they must possess reading and writing abilities in
order to become “independent learners of academic material” (p. 4). Another similarity
between this study and the researcher’s study was that the majority of the writing student
population did not find the writing prompt interesting. Although the researcher’s
69
participants did not feel the topic was too American culture, it perhaps did not target the
participants’ schema and therefore the topic was found uninteresting.
Moreover, the sample size was also closely related (Thot-Johnson’s &
Vanniarajan=77, the researcher=74). However, when students were questioned on their
self-perceived level of writing ability in English in Thot-Johnson’s and Vanniarajan’s
study, “24 students (31.2%) felt that their writing ability was below average, 36 students
(46.8%) felt it was average, and 4 students (5.2%) perceived that their ability was good”
(p. 8). These results are for a total of 64 students. The study did not report on the writing
ability of 13 of the students sampled. And when students were asked the same question
on the researcher’s study, 3 students (4.5%) felt their writing ability in English was below
average, 23 students (31.08%) felt it was average, 8 students (10.81%) reported it was
very good, 2 students (2.70%) felt it was excellent, and 38 students (51.35%) felt their
writing ability in English was good. It was interesting to reveal that 79.9% of students
whose native language is Spanish felt that their writing ability in English was good. The
research suggested that although Spanish is the language most often used by students at
the college, it did not affect students writing ability in English.
As noted, the study most closely related to the researcher’s study was Thot-Johnson
and Vanniarajan (2002). And although the studies had many similarities, they differed in
geographical location. Thot-Johnson and Vanniarajan conducted their study in California
(West Coast), whereas the researcher conducted her study in Florida (East Coast).
Moreover, Hoyt and Sorenson’s (2001) study revealed the importance of validating
standardized testing and accurate placement of students. They stressed that standardized
tests that asses writing skills are problematic because of the “difficulty in accurately
70
measuring writing abilities” (p. 33). The same was true for this study in regards to the
Florida College Basic Skills Exit Test. The ENC0021 exit test cannot be taught in terms
of content. Again, what instructors need to focus on is teaching students how to learn to
write instead.
The researcher did notice however that at least one study had a difference outcome.
While Hidi and Harackiewicz’s (2000) study revealed that students’ underpreparedness
was a lack of motivation and effort, the researcher’s study indicated that 53.4% of the
participants did not give up on what they wanted to say in their final exam essay.
Students in this study as compared to Thot-Johnson and Vanniarajan's (2002) study used
16 of the 28 strategies questioned on the survey. They use strategies they felt comfortable
with and strategies they knew well.
After reading the research studies, the researcher was aware that students’ lack of
preparedness at the secondary level was affecting their ability to perform well on the CPT
as well as on the ENC0021 exit test. The researcher’s findings were consistent with the
literature except in terms of geographical area and age group.
The researcher’s study contributes to the literature by studying a sample size that
ranged in age from 18 to 54 and where the primary language of 79.7% of the participants
is Spanish.
A number of limitations should be noted about this study’s results. As a general
caveat, the use of a survey design warrants caution when interpreting the study results.
Specifically, the survey asked students to retrospectively recall which writing strategies
that they used. It is difficult to determine whether these retrospective accounts accurately
reflect what students actually use in practice. The accuracy of these survey questions
71
requires that students are cognitively aware of the strategies that they are employing as
they write. The level of awareness that allows students to accurately answer these survey
questions probably varies considerably across people.
Another limitation of this study is that it was not possible to link student reports of
strategy use to their actual test performance. Anonymity requirements did not allow the
surveys to contain identifying information, so it was not possible to link a survey record
to course performance or to test performance. Ideally, it would have been desirable to
determine whether the use of certain strategies is associated with better course
performance or better exam performance. Unfortunately, this was not possible.
Third, generalizability is always something that should be considered when
interpreting the results from a study. The student population from which this study’s
sample was drawn is quite different from the general college student population.
Specifically, the students ranged between 18 and 54, with a mean of M = 25.24 (SD =
8.84). This is a somewhat non-traditional age range for college students. Also, the vast
majority of students (79.7%) in the sample reported that Spanish was their native
language, and only 10.8% of students reported English as their native language. The high
rate of Spanish language speakers is not surprising, given that the study was conducted in
a large metropolitan city in South Florida, but it is not representative of the broader
college student population. Finally, many of the students reported relatively low levels of
reading and writing ability. This may or may not be representative of students at other
universities.
This investigation was also limited to the writing developmental students enrolled at
the college used in this study. An experimental group was selected to represent the entire
72
writing student population at the college. In doing so, it was believed that the outcome
would be representative of the effectiveness of the Florida College Basic Skills Exit Test
administered to developmental writing students at the community college level. This
study was limited to the faculty members teaching ENC0021 and ENC1101. Other
faculty teaching subsequent sections of writing were not included in the study.
Consequently, the faculty will not have access to the data and end results to possibly aid
their own developmental students. Furthermore, the shortcoming ingrained in the use of
questionnaires to collect the type of data needed for this study might have impacted the
validity or reliability of the data.
While this study adds to the literature, it is recommended that future researchers
should take these findings and conduct additional research on students’ use of effective
strategies in the classroom through observation. And, compare if the effective strategies
correspond with the ones that this study found were used most frequently.
The data also revealed that 44 (59.5%) students felt that there was not enough time to
complete the essay part of the exit test. And 38 (51.4%) students felt there was not
enough time to complete the grammar portion of the exit test. Given these data, more
time allotted on the Florida College Basic Skills Exit Test is recommendation. It is
inferred that if more time was given, more students would have done better on the test.
It is also recommended for instructors to assess their students’ proficiency in the
English language and use of writing strategies. They can do this by administrating a
diagnostic assessment in writing at the beginning of each ENC0021 course. Once they
have scored the diagnostic assessment, instructors need to examine and determine the
73
students’ level of learning and achieved practices. Instructors should also determine how
results will be disseminated.
Finally, with proper techniques on how to write effective essays, proper use of writing
strategies and cognitive skills in English, instructors can teach ENC0021 students on how
to successfully achieve a passing score on the Florida College Basic Skills Exit Test.
