1. PBL, AN APPROACH
TOWARDS LEARNER
CENTERED LEARNING
Dr Zia ul Islam

2. Introduction
■ Problem-based learning (PBL) as a teaching strategy and
curricular design began over more then fifty years ago at
McMaster University in Canada.
■ The PBL process was pioneered by Barrows and Tamblyn at
the medical school program at McMaster University in Hamilton in
the 1960s
■ PBL reverses the traditional approach to teaching and learning
■ It starts with individual examples or problem scenarios which
stimulate student learning

3. How it is started
■ Problem-based learning did not appear out of the blue but had several
precursors:
 First in the work of Dewey who established an experimental school at the
University of Chicago based on the idea that learning is more interesting if
the learner is actively involved in his own learning
 The second source of influence was the Case Study Method pioneered at
Harvard University in the 1930s of the previous century.
 The third source of influence to be described is Jerome Bruner’s “learning by
discovery” from which the idea that a problem could be the starting point for
learning originated

4. How it works?
■ PBL is both a curriculum and a process
As a curriculum
It consists of carefully selected and designed problems that demand
from the learner`s acquisition of critical knowledge, Problem solving
proficiency, self-directed learning strategies, and team participation
skills.
As a process
It replicates the commonly used systemic approach to resolving
problems or meeting challenges that are encountered in life and
career

5. As an Instructional strategy
■ Problem-based learning (PBL) is an instructional method that
challenges students to "learn to learn," working cooperatively in
groups to seek solutions to real world problems
■ These problems are used to engage students' curiosity and initiate
learning the subject matter
■ PBL prepares students to think critically and analytically, and to
find and use appropriate learning resources
■ PBL can be used as a framework for modules, courses, programs,
or curricula

7. Advantages
 Facilitates the acquisition of basic competences
 It encourages a deep approach to learning
 It prepares students for the adult learning approach they need for
a lifetime of learning in the health care professions
 PBL helps in curriculum planning by developing core knowledge
 Ensuring relevance of content
 Integrating student learning and providing them with model cases

8. Disadvantages
■ Students may fail to develop an organized framework for their
knowledge
■ Student Unpreparedness. .
■ Time-Consuming Assessment.
■ It may inhibit good teachers sharing their enthusiasm for their topic
with students and student identification with good teachers
■ Teachers may not have the skills to facilitate PBL
■ Inadequate resources

9. Characteristics of a Problem-based
Activity
■ An ill structured, complex problems provide the focal point(s) and
stimuli for the learning process
■ Learning is student-centered
■ Teacher acts as a coach or facilitator.
■ Students work in small groups to solve/provide multiple solutions
to problems
■ Learner assessment is enhanced by self and peer assessment.

10. Enhance students’ achievement of
 Application of problem solving in new and future situations
 Creative and critical thought
 Adoption of holistic approach to problems and situations
 Successful team collaboration
 Identification of learning weaknesses and strengths
 Promotion of self-directed learning
 Effective communication skills
 Leadership skills

11. It helps student in
 Construct an extensive and flexible knowledge base
 Develop effective problem-solving skills
 Develop self-directed, lifelong learning skills
 Become effective collaborators
 Become intrinsically motivated to learn.

12. Approaching the Problem(s)

13. Approaching the Problem(s)
■ 1. Introducing the concept and rationale for use of a PBL problem
within the course/ module/unit
■ 2. Setting the stage.
a. Roles and responsibilities of the various group members.
b. In PBL, the recommended group size is from 4to 6 students. Each student
can take (and hopefully rotate) the role of leader / encourager, reporter /
skeptic, animator / presenter and recorder / scribe.
