microbiology and community medicine. PBL sessions do not cut
across subjects. The groups are multinational and of both sexes.
The facilitators try to smoothen out the group dynamics in case
of problems but do not usually provide answers to questions. The
students solve the problem in approximately an hour and then
present their solutions. During the presentation, the student pre-
senters occupy center stage and the facilitators sit in a corner. The
topic then is opened for discussion to the house. After the presen-
tation, the facilitators sum up the discussion and may focus on
points which did not emerge or were not emphasized during the
presentation and subsequent discussion.
The Department of Pharmacology uses a mixture of didactic
lectures and PBL/PSL sessions. The theoretical bases of topics are
covered during the didactic lectures and students solve problems
in pharmacology and therapeutics during the PBL/PSL (practical)
sessions (lasting 2.5 h). A class of 37 or 38 students is divided into
five groups of 7 or 8 each. Three faculty members/postgraduate
students act as facilitators who divide their time among the dif-
ferent groups.
Solving clinical problems, selecting a personal or P-drug for a
disease condition, verifying the suitability of the selected P-drug
for a particular patient and writing a prescription, analyzing drug
advertisements and promotional material and communicating
drug and non-drug information to simulated patients are typical
exercises carried out during the PBL/PSL sessions.
Evaluation of Our Experiences
MCOMS is using a modification of PBL which may be more
practicable in resource-limited settings. Our overall experiences
with the PBL/PSL and the role of facilitators have been positive.
Initially it was difficult for facilitators to relinquish the tradi-
tional authority associated with a teacher. Resisting the urge to
provide answers and directing the students towards solving the
problems on their own was sometimes difficult. Not all students
participated fully in the group deliberations and activities. Fa-
cilitators tried to let the group solve this problem on their own.
Sometimes indirect pressure was used to induce participation.
Many students eventually did participate, but some proved to be
recalcitrant. Formative assessment during the sessions has re-
cently been introduced. Student participation in the group ac-
tivities, group leadership skills and communication abilities have
been assessed.
The large batch size (37 or 38 students) has sometimes created
disciplinary problems. With a fellow student on stage and the fa-
cilitators sitting in a corner, certain students have tried to take
advantage of the situation. Also, students are so used to the con-
cept of a teacher that they constantly turn towards the facilitators
even though they sit in a corner.
While the sessions should be continued, modifications could
be considered. A greater part of the student learning could be ac-
Introduction
Problem-based learning (PBL) is grounded in the belief that
learning is most effective when students are actively involved and
learn in the context in which knowledge is to be used [1]. PBL is
now an accepted component of medical school programs in the
United States, Canada, the United Kingdom, the Middle East and
Asia [2, 3]. The World Health Organization has recommended
PBL of pharmacotherapy as a key component for promoting the
more rational use of medicines [4].
PBL is gradually becoming more common in Asian medical
schools, especially those in Southeast Asia [5] where the culture
values loyalty and deference towards the teacher. Asian students
have been described as shy, lacking self-esteem and extremely po-
lite [6]. They are reserved in class for fear of being wrong [6]. Med-
ical professionals who have used PBL with Southeast Asian stu-
dents have reported weak group process and interaction skills
among students.
Experience of the Manipal College of Medical Sciences
The Manipal College of Medical Sciences (MCOMS), Pokhara,
Nepal, admits students from Nepal, India and Sri Lanka for the
undergraduate medical (MBBS) course. Students are admitted af-
ter 12 years of schooling, which include physics, chemistry and
biology in the last 2 years. The 12th standard in South Asia is
equivalent to British A levels. Some students also join after com-
pleting a degree (3 years of study after the 12th standard). Phar-
macology is taught during the first 4 semesters of the MBBS
course in an integrated organ-based system with the other basic
science subjects (anatomy, physiology, biochemistry, pathology,
microbiology and community medicine) [6]. There are regular
hospital visits. The clinical subjects are usually taught from the
5th semester.
The Department of Pharmacology conducts problem-stimu-
lated learning (PSL) sessions [7] and has been using this learning
modality since the middle of 2001. The clinical Departments of
Medicine, Surgery, Obstetrics and Gynecology and Pediatrics
have been using PBL since the beginning of 2002. The Depart-
ments of Pathology and Radiology have not yet adopted PBL, and
it is not a common learning methodology in anatomy, physiology,
