    REVIEW OF RELATED LITERATURE AND RESEARCH PARADIGM

    This chapter presents Review of Related Literature, Theoretical Framework,

    Conceptual Framework, Statement of Hypothesis and Definition of Terms.

    CONSTRUCTIVISM

    Inquiry-based learning stems from a wide range of research and has its roots in

    constructivism. In constructivism, the key tenet is that an individual learner must actively

    construct knowledge and skills (Bruner, 1990). Despite whether or not there is an

    objective reality, it is the individual who constructs their own reality through their

    experience and interaction with the environment. As an individual experiences

    something new, he or she filters this information through mental structures (schemata)

    that incorporate prior knowledge, beliefs and preconceptions to make sense of the

    information (Prince & Felder, 2006). This theory of learning goes back many centuries,

    but in more recent times the research of John Dewey, Jerome Bruner and Lev

    Vygotsky, together with Jean Piagetswork on developmental psychology, has resulted

    in the broad approach of constructivism. There are two main forms of constructivism:

    cognitive and social. Cognitive constructivism draws mainly on Piagets theory of

    cognitive development. Piaget proposed that individuals must construct their own

    knowledge and that they build knowledge through experience. These experiences allow

    creation of schemas or mental modes and thus lead to learning. In contrast to cognitive

    constructivism, social constructivists place more emphasis on the social context of

    learning. Vygotsky is the main proponent of social constructivism and suggested that

    cultural history, social context and language play an important role in the pattern and

    rate of development of children. Vygotskys concept of the zone of proximal

    development argues that individuals can, with the help of a more experienced peer,

    master concepts and ideas that they cannot understand on their own (Vygotsky, 1978).

    COMPARISON OF PBL AND IBL

    Inquiry-Based Learning (IBL)

    Inquiry-based learning is a pedagogy which best enables students to experience

    the processes of knowledge creation (Spronken-Smith, 2008). The key attributes

    include learning stimulated by inquiry, a student or learning centered approach in which

    the role of the teacher is to act as a facilitator, a move to self-directed learning, and an

    active approach to learning. This is also a process where students are involved in their

    learning, formulate questions, investigate widely and then build new understandings,

    meanings and knowledge (Alberta Education, 2004). That knowledge is new to the

    students and may be used to answer a question, to develop a solution or to support a

    7

    position or point of view. The knowledge is usually presented to others and may result in

    some sort of action.

    Constructivism

    IBL and Constructivism

    The power of an inquiry-based approach to teaching and learning is its potential

    to increase intellectual engagement and foster deep understanding through the

    development of a hands-on, minds-on and research-based disposition towards

    teaching and learning. Inquiry honours the complex, interconnected nature of

    knowledge construction, striving to provide opportunities for both teachers and students

    to collaboratively build,test and reflect on their learning. According to the constructivist

    theory of learning, effective teaching must offer experiences that: build on what students

    already know so they can make connections to their existing knowledge structures;

    encourage students to become active, self-directed learners; provide authentic learning

    opportunities; involve students working together in small groups (i.e. in collaborative or

    cooperative learning). Rather than being the sage on the stage in a transmission mode

    of teaching, constructivist teachers should act as guides on the side, providing

    opportunities to test the adequacy of students current understandings (Hoover, 1996).

    Hoover also argues that because new knowledge has to be actively built, it takes time to

    do so. This means that any constructivist courses should allow ample time for student

    reflection about new experiences and how these fit or not with current understandings.

    IBL as an Inductive Approach

    Inquiry-based learning falls under the realm of inductive approaches to teaching

    and learning. Inductive approaches to teaching and learning begin with a set of

    observations or data to interpret, or a complex real-world problem, and as the students

    study the data or problem they generate a need for facts, procedures and guiding

    principles. Inductive teaching encompasses a range of teaching methods including

    inquiry-based learning (IBL), problem-based learning (PBL), project-based learning,

    case-based teaching, and discovery learning(Prince and Felder, 2006). They classify

    the teaching methods by considering the context for learning and other features, such

    as the amount of student responsibility for their learning and the use of group work.

    Common to all these inductive methods of teaching are (a) a student- or learner-

    centered approach (Kember, 1997) in which the focus of the teaching is on student

    learning rather than on communicating defined bodies of content or knowledge; (b)

    active learning is about learning by doing (Gibbs, 1988, Healey & Roberts, 2004) and

    may involve, for example, students discussing questions and solving problems (Prince

    & Felder, 2006); (c) the development of self-directed learning skills in which students

    take more responsibility for their own learning; (d) a constructivist theoretical basis

    which proposes that students construct their own meaning of reality; it is the students

    who create knowledge rather than knowledge being imposed or transmitted by direct

    instruction.

    Problem-Based Learning (PBL)

    Problem-based learning is based on research in the cognitive sciences on how

    we learn. PBL improves learning (Spence, 2010).Problem-based approaches to

    learning have a long history. They are one of many instructional approaches that situate

    learning in a meaningful task, such as case-based instruction and project-based

    learning. In the traditions of Kilpatrick and Dewey, these approaches argue for the

    importance of practical experience in learning. Problem-based learning is part of this

    tradition of meaningful, experiential learning.In PBL, students learn by solving problems

    and reflecting on their experiences(Barrows and Tamblyn, 1980). PBL is well suited to

    helping students become active learners because it situates learning in real-world

    problems and makes students responsible for their learning. It has a dual emphasis on

    helping learners develop strategies and construct knowledge (Cognition and

    Technology Group at Vanderbilt, 1997; Collins et al., 1989; Hmelo and Ferrari, 1997;

    Kolodneret al., 1996).PBL is focused, experiential learning organized around the

    investigation, explanation, and resolution of meaningful problems (Barrows, 2000;Torp

    and Sage, 2002).

    The focus of PBL is in organizing thecurricular content around problem scenarios

    rather than subjects or disciplines.Students work in groups or teams to solve or manage

    these situationsbut they are not expected to acquire a predetermined series of

    rightanswers. Instead they are expected to engage with the complex

    situationpresented to them and decide what information they need to learn andwhat

    skills they need to gain in order to manage the situation effectively (Savin-Baden,

    2000).There are many different ways of implementing problem-based learningbut the

    underlying philosophies associated with it as an approach are broadlymore student-

  • 8/10/2019 Chapter 2-Not Final

    6/15

    10

    centred than those underpinning problem-solving learning.This is because students are

    offered opportunities, through problem-basedlearning, to explore a wide range of

    information, to link the learning withtheir own needs as learners and to develop

    independence in inquiry. Problem-based learning is thus an approach to learning that is

    characterized byflexibility and diversity in the sense that it can be implemented in a

    varietyof ways in and across different subjects and disciplines in diverse contexts.As

    such it can therefore look very different to different people at differenttimes depending

    on the staff and students involved in the programmesutilizing it. However, what will be

    similar will be the focus of learningaround problem scenarios rather than discrete

    subjects.

    The notion of learning through solving or managing problems is not new.

    However, the emergence of problem-based learningas a specific concept and approach

    emanated from the work of Barrows,who discovered through his research into medical

    education that medicalstudents and residents for the most part did not seem to think at

    all.Some gathered data ritualistically and then tried to add it up afterwards,while others

    came up with a diagnosis based on some symptom or sign,never considering possible

    alternatives (Barrows and Tamblyn, 1980).Problem-based learning was developed at

    McMaster University in Canadawhere Barrows set out to design a medical school

    curriculum based solelyon small group, student-centred learning. The rationale for

    problem-basedlearning stemmed from years of observing experts engaged in clinical

    reasoning,resulting in Barrows and Tamblyn (1980) claiming that problem-

    basedlearning was based on two assumptions. The first was that learningthrough

    problem situations was much more effective than memory-basedlearning for creating a

  • 8/10/2019 Chapter 2-Not Final

    7/15

    11

    usable body of knowledge. The second was that themedical skills that were most

    important for treating patients were problem-solvingskills, rather than memorization. Yet,

    what was important about theapproach adopted at McMaster was that the focus was not

    on problem-solvinglearning whereby individual students were expected to answer

    aseries of questions from information supplied by a lecturer. Instead theywere asked, in

    small teams, to explore a problem situation. Through suchan exploration students were

    expected to examine the gaps in their ownknowledge and skills in order to decide what

    information they needed toacquire in order to resolve or manage the situation with

    which they werepresented.

    As Barrows and Tamblyns model was being developed during the early1970s

    there was also increasing interest in the medical world in studentsability to develop

    problem-solving skills. Other research indicated that medicalstudents were lacking in

    problem-solving skills (McGuire,1972, 1985). In parallel, there was interest in

    understanding studentsapproaches to problem-solving activities and with it came

    criticism of theunnaturalness of much laboratory research in cognitive psychology

    (Neisser,1982). This resulted in wide-ranging studies of students problem-

    solvingabilities with a growing emphasis on the use of qualitative methods(Laurillard,

    1979, 1984). This early research into problem-solving and clinicaldecision making

    prompted interest and research within professionsallied to medicine (Higgs, 1990; Terry

    and Higgs, 1993). Therewas, however, a shift away from focusing on the generation

    and testing ofhypotheses as a means of arriving at a major clinical decision, and a

    greateremphasis on clinical reasoning as a process occurring throughout

    clinicalpractice. This work in part stemmed from some of the early studiesinto problem-

  • 8/10/2019 Chapter 2-Not Final

    8/15

    12

    based learning where it was increasingly seen that learningproblem-solving abilities in

    situations isolated from a relevant context didnot facilitate effective transference to the

    clinical environment. What becameincreasingly apparent was that although problem-

    solving skills were a usefulacquisition for students, it was the application of such skills to

    a clinicalsituation that was vital. This was because problem-solving learning tendedin

    the main to be seen as a step by step approach to solving a problem thatdenied the

    complexities and difficulties of a clinical situation. In contrast,problem-based learning

    confronts students with the challenge to manage aclinical situation, which requires them

    to incorporate diverse resources suchas existing knowledge, data collection,

    interpersonal skills, reflection andreasoning ability in order to meet that challenge.

    The bulk of the literature in the late 1970 s and 1980s argued for the useof

    problem-based learning for four key reasons. These were,first, to develop students

    reasoning skills; second, to enable learning to takeplace within a context that was

    relevant to the students; third, to ensurethat learning was attuned to the world of work;

    and finally to promotestudents self-directed learning abilities, that is, learning that

    fostered independent inquiry. A number of articles at that time cited lists of

    advantagesof problem-based learning over more traditional ways of learning

    (Neame,1982; Coles, 1985) and others suggested that problem-based learning

    wasfound to be more enjoyable and stimulating by staff and students involvedin such

    programmes (Olson, 1987). However, few seemed to tackle manyof the underlying

    assumptions of problem-based learning or relate suchassumptions to current trends in

    the broader context of changes withinhigher and professional education.

    equipped to undertake tasks, to carry outinstructions, and to work with others, but they

    are not necessarily able to analyze or critique the situation in which they find

    themselves or the informationwith which they have been presented. Yet what is on offer

    throughproblem-based learning are opportunities for students to develop the

    requiredkey skills but in a context where they are also encouraged to developthe ability

    to critique issues and information, and to take up a positiontowards the situation with

    which they have been presented.

    PBL and the Learning Cycle

    In PBL, students work in small collaborative groupsand learn what they need to

    know in order to solve a problem. The teacher acts as a facilitator to guide student

    learning through the learning cycle. In this cycle, also known as the PBL tutorial

    process, the students are presented with a problem scenario. They formulate and

    analyze the problem by identifying the relevant facts from the scenario. This fact-

    identification step helps students represent the problem. As students understand the

    problem better, they generate hypotheses about possible solutions. An important part of

    this cycle is identifying knowledge deficiencies relative to the problem. These

    knowledge deficiencies become what are known as the learning issues that students

    research during their self-directed learning (SDL). Following SDL, students apply their

    new knowledge and evaluate their hypotheses in light of what they have learned. At the

    completion of each problem, students reflect on the abstract knowledge gained. The

    teacher helps students learn the cognitive skills needed for problem solving and

    collaboration. Because students are self-directed, managing their learning goals and

    15

    strategies to solve PBLs ill-structured problems (those without a single correct solution),

    they also acquire the skills needed for lifelong learning.

    IBL versus PBL

    Defining the relationship between IBL and PBL has been fraught with difficulty.

    Most researchers acknowledge an overlap in the approaches but there are conceptual

    differences in distinguishing the two. Prince and Felder (2006) suggest that the major

    difference between IBL and PBL lies in the type of question with PBL by definition

    involving complex, ill-structured open-ended real world problems, while IBL may

    possibly use such problems. This distinction is in contrast to many researchers such

    asPlowright& Watkins (2004), Elton (2006); McMaster University (2007) who suggest

    that PBL usually focuses on questions to which answers already exist, while IBL often

    involves open-ended questions. A further difference postulated by McMaster University

    is that PBL has a shorter timescale, while IBL can be for a sustained period. Kahn and

    ORourke (2004) suggested that PBL was a subset of IBL, along with other pedagogies

    such as project work and small scale investigations. Spronken-Smith, et al. (2008) used

    the notion of collaboration to distinguish. While IBL can be done in collaborative groups,

    PBL is usually done this way. In considering the debate Spronken-Smith, et al. (2007)

    concluded that as a guide, it appears that PBL is a more prescriptive form of IBL, and

    thus PBL is seen to be a subset of IBL, and both IBL and PBL are subsets of active

    learning.

    Theoretical Framework of the Study

  • 8/10/2019 Chapter 2-Not Final

    12/15

    16

    Figure 1 shows different theories from various philosophers. The diagram

    illustrates several theories that date back to the 18 thcentury. Kilpatrick (1918, 1921) and

    Dewey (1938) theorized that students learn through experience which becomes a

    theoretical basis in the development of problem-based learning. Furthermore, due to the

    emergence of experiential learning theory which was also strongly supported by

    Deweys learning theory, Jerome Bruner (1990) worked on constructivism in which

    individual learner must actively construct knowledge and skills. This resulted to the two

    forms of constructivism: Lev Vygotskys Social Constructivism and Jean Piagets

    Cognitive Development.Piaget proposed that individuals must construct their own

    knowledge and that they build knowledge through experience. These experiences allow

    creation of schemas or mental modes and thus lead to learning. Meanwhile,

    Vygotskysuggested that cultural history, social context and language play an important

    role in the pattern and rate of development of children. Moreover, his concept of the

    zone of proximal development argues that individuals can, with the help of a more

    experienced peer, master concepts and ideas that they cannot understand on their own.

    These two approaches lead to the development of inquiry-based learning. Finally,

    inquiry-based learning and problem-based learning are just subsets of active learning.

    Research Paradigm

    Figure 2 shows the paradigm of the study which includes the dependent and

    independent variables as well as the moderating and intervening variables. The

    independent variables or the causal variables in the study are the two approaches to be

    tested: the IBL and PBL. The dependent variables of the study are the students level of

    performance and their level of interest towards science. The teachers competence in

    employing the two approaches is considered as the moderating variable because it

    modifies the dependent and independent variables. On the other hand, the availability of

    resources which will greatly help in the utilization of IBL and PBL is considered as the

    intervening variable because this may surface upon the utilization of the two

    approaches and therefore influence the dependent variable.

    In order to have further understanding of this study, the following terms are

    conceptually and operationally defined:

    Students Performance. This is defined as the student achievement in relation to a

    prescribed learning outcome (Mendoza, 2008). This also refers to students

    achievement which is measured in terms of the results in the pre-test and post-test after

    the exposure of IBL and PBL.

    Students

    Interest. This refers to the students motivation in learning. This is also

    defined as the students eagerness in learning science and is measured using the

    Modified Attitudes towards Science Inventory (mATSI) by Weinburgh and Steele.

    Resource Availability.This refers to the extent to which resources are made available

    to achieve the aims and to implement something. (AMLR, 2013) This is also defined as

    the extent to which resources necessary for teaching are made available in employing

    IBL and PBL.
