Background of the ProblemsForeign students contribute about $13.5 billion to the U.S. economy each year through their tuition and fees and living expenses.
Every 31 seconds a new immigrant enters USA, but 60% are
Limited English Proficiency (LEP) (Camarota, 2005).47 million people speak language other than English, and 23 millionpeople speak English less than “very well” (U. S. Census Bureau,2005).
CALL programs has become a new solution for ESL education.Definition of CALL programs : An approach to language teachingand learning, where the computer is used to assist the presentation,reinforcement, and assessment of the learning material (Davies,2002).

A student who lives in a higher Digital Access Index (DAI) scoringcountry may have more opportunities to get the benefits of computer technologies and the Internet, and can gain moreopportunities to increase their individual computer literacy skills(International Telecommunication Union, 2003).
Students of varying levels of English proficiency in English do havediffering perceptions of the use of technology (Doll, 2007).
Lower level of English proficiency students were enthusiasticabout the CALL environment; higher level of English proficiency students need more significant learning inputs and might bedifficult to perceive an improvement through regular CALLprograms for their English skills (Hayes & Hicks, 2004)

and a p value shown in Scheffe test. A Least Significant Difference (LSD) test was conducted.
The result yielded a significant difference between the following pairsof age groups:

LEP student’s age range was a factor that causedsignificant differences toward students’ “Usefulness”perceptions when using CALL programs
Three reasons may contribute to the result:1. Generations2. Levels of English Proficiency 3. Duties
According to the qualitative interviews, the older students hadto spend more time on their jobs and household duties. They had very little time for English study or computer use at home.This might account for some of the difference in “Usefulness”scores between age groups.

The age difference could not be regarded as an influentialfactor affecting older adults engaging in Web-searchingactivities…….. If we can provide more trainings andopportunities to older adults, older adults may overcomethe age difference and enjoy the benefits of computertechnologies more than younger users (Kubeck, Miller– Albrecht, & Murphy, 1999) .

Student’s native language and culture background may influence his or her perception regarding the use of computer technology for enhancing their learning (Zoe &DiMartino, 2000).
Through the qualitative interview, one ESL instructorpointed out that Asian students are often good at computertechnology. Their countries usually have more technology infrastructure, so they can get more technology exercise
opportunities.The transfer of prior linguistic and cognitive knowledgefrom the first language to the second language is arequisite learning process for LEP students (O’Malley &Chamot,1990) .

Major FindingsResearch Question ThreeWhat are the advantages and disadvantages of CALL programs inactual ESL teaching and learning? CALL programs have a positive influence on their ESL teaching andlearning.
Major Advantages:1. Increase access to authentic materials for teaching and learning English2. Provide more opportunities for practice through experiential learning3. Offer more varied learning situations that enhance learning motivation
and achievement.
LEP students: more online interactive opportunities; more learningresources .
ESL instructors: prefer the traditional face-to-face interactions. Focus onevaluation and record students’ learning progresses.

Major FindingsResearch Question Three (cont.)
Major DisadvantageESL instructors:
1. may not totally align with beginning level English learners’needs;
2. may reduce English learners’ opportunities to explore otherlearning resources; and
3. may increase the teaching and learning loads
LEP students: over-use of CALL programs may influencetheir spelling ability . The spell-correcting function of CALLprograms may help to recheck their writing, but it may prevent them from learning to spell.

“The use of the computer does not constitute a method.Rather, it is a medium in which a variety of methods,approaches, and pedagogical philosophies may beimplemented” (Garrett, 1991, p. 75).
No matter what many functions CALL programs provide,they are still no more than media for teaching andlearning. The effectiveness of CALL programs does notlie in the medium alone but in how the programs areused and the quality of personal teaching and guidancethat accompany them.

Major FindingsResearch Question Four
What is the role of CALL programs in current ESLinstructions?
Time spent on CALL programs: ESL instructors: 1. the length of the semester
2. the content of textbook
LEP students: technology experience backgroundsWithout technology background or with little technology
knowledge, students spend little time or none on usingtechnology to enhance their learning.Students who have rich technology experiences often spendmore than ten hours per day for using the computer and theInternet.

Major FindingsResearch Question Four (cont.)
“Tool” role:1. vary their teaching and learning paths2. provide more interactive activities3. facilitate the effectiveness of teaching and learning.
“Tutor” role: CALL programs can offer reading, vocabulary, and other kinds of practice to evaluate students’ works and keep their records.
“Tutee” role:Each student has individual learning needs and the computer is notable to adapt to different learning styles of the student. CALL
programs should follow and satisfy English learners’ needs.

Computers play various roles that deeply impact ESLteaching and learning methods (Warschauer & Kern,2000; Wiazowski, 2002)
The theoretical framework underlying CALL programs is very difficult to define because CALL programs exist inso many different forms. The specific role of CALLprograms often depends upon different needs anddifferent situations (Kemmis, Atkin, & Wright, 1977;Higgins, 1988, Taylor, 1980).

Major FindingsResearch Question Five
What are the second-language learning efficiency expectations of LEP students and ESL instructors utilizing CALL programs?
Satisfaction of current CALL
All ESL instructors: Current CALL programs are good enough forESL education.Four LEP students: CALL programs are not perfect enough to meettheir learning needs. (For example: Translation Function)

Major FindingsResearch Question Five (cont.)
English skills can be improved effectively
A. The variety of CALL programs permits different users to addressdifferent learning goals and produce different learning results.
B. Because there are no solid guidelines and standards , some instructors andstudents become confused with the functions and abilities of current CALL
program.

Major FindingsResearch Question Five (cont.)
Expectations of future CALL programs:1. The price of computer, CALL software, and Internet
connection should be reduced
2.The future CALL programs should be easier to use“To beginning level learners, computers or CALLprograms are difficult to operate sometimes”
3. Should have more human intelligence to understandlearners’ needs and can give students correct feedback immediately

Software of CALL programs is still imperfect, and theirfunctions are limited. Due to the limitations of computer’s artificial intelligence, current computertechnology is unable to deal with learner’s unexpectedlearning problems and response immediately as teachersdo (Warschauer, 1996).The reasons for the computer’s inability to interacteffectively can be traced back to a fundamentaldifference in the way humans and computers utilizeinformation (Dent, 2001).

Conclusion
LEP students come from different countries and havedistinct learning habits and attitudes toward the use of technology for enhancing English learning. It is importantthat educational leaders and ESL instructors pay greaterattention to students’ personal factors and their learningneeds . When investments in CALL programs are made, it isimportant that the CALL programs be useful and easy touse for all populations served. Failure to evaluate CALLapplications continuously and to make improvements inthe development and deployment of CALL software canresult in non-use or ineffective use.

Conclusion (cont.)Lack of technology knowledge is a major barrier to realizethe advantages of CALL programs. Educational leadersand administrators should face the problem and developtechnology training plans to ensure that all ESL teachersand LEP students have the knowledge and skills to apply CALL programs in their teaching and learning.
To identify what role CALL programs played in theclassroom is important because each instructor’s andstudent’s perceptions of the roles of CALL programs willfurther influence their decisions on how to apply CALLprograms in their language teaching and learning.

Conclusion (cont.)
To overcome the price problem and ensure each studenthas the equal opportunity to get CALL programs forenhancing their English Learning, educational leadersand administrators may have to negotiate with computerproducing factories and software companies to reduce theselling prices of computers and CALL software.
To improve the artificial intelligence and the ease of useproblems, educational leaders and administrators may have to communicate with software designers to designmore appropriate CALL programs for ESL teaching andlearning.
