Abstract - Routinely for teaching large number of
students, didactic lecture (DL) is used which is a
teacher centered process, promotes passive learning
and fails to motivate the students. Case based lecture
(CBL) is an interactive student centered approach
and promotes active learning. Hence the present
study was undertaken to assess whether CBL is an
effective teaching tool for the Medical Microbiology
and to evaluate students’ perception about this new
methodology.
This study was conducted at department of
Microbiology, JNMC, AMU, Aligarh. 30 students from
second year MBBS were included in the study. First
students had conventional didactic lecture (topic-
Mycobacterium tuberculosis).feedback regarding
didactic lecture topic was taken. Next time, these 30
students were exposed to case based lecture (topic-
Mycobacterium leprae).
In the present study, same students participated in
both the sessions. Students found CBL as a more
effective tool for improving their learning,
communication and analytical skills (99.9%, 99.9%,
99.6% respectively). Many students were (92.9%)
neutral towards DL as regards clearance of their
basic concepts. Indicating that case based lecture is
an effective method in a large classroom setting than
didactic lecture.
To improve the outcome of didactic lecture and to
promote active learning, CBL can be an effective
teaching tool.
Key Words: case based lecture, medical
microbiology, active learning
1. INTRODUCTION:
In medical education, there are various
methodologies of teaching and learning each having
its own advantages and disadvantages. Routinely for
teaching large number of students, didactic lecture
(DL) is used. It is a teacher centered process,
promotes passive learning and fails to motivate the
students. Therefore in last few decades; concept of
active learning has evolved (Sprawls et al, 2008).
Case based learning is an interactive, student
centered approach and promotes active learning
(Thistlethwaite et al, 2012). It engages students in
discussion of clinical case that resembles real life
situation and provides information such as history,
physical findings and laboratory results (Williams et
al, 2005). Students interact with each other and work
together as a group to solve the case. The instructor’s
role is that of facilitator. But this is a small group
teaching method and requires large number of
faculties.
In medical microbiology, students learn about
various microorganisms and factors that lead to
disease. In reality, patients present with various
signs and symptoms which has to be correlated with
infectious agents and host’s response (Neal et al,
2012). In pure didactic lecture, this correlation is not
possible. Incorporation of case in didactic lecture can
solve this problem. Hence the present study was
undertaken to assess whether interactive case-based
lecture (CBL) is an effective teaching tool for the
Medical Microbiology and to evaluate medical
students’ perception about this new methodology.
