Background & Objective: Education is one of the most basic necessities of human communities
and an important base of continuous development. Variation in teaching methods is an obvious
need in our complicated world and selecting the most appropriate teaching method is the key issue
at every stage of learning process. The aim of this study was to compare the efficacy of two
teaching methods of group discussion and lecturing on the learning rate of the students of
Laboratory Medicine in Medical Parasitology and Mycology course in Yazd Shahid Sadoughi
University of Medical Sciences and Health Services during the academic year of 2005-006.
Methods: This semi-experiential study carried out on 50 students of Laboratory Medicine
selected by purposive sampling method. The students divided into two groups matched for age,
sex and average scores of their last two semesters. One group was taught by using group
discussion method and the other group by the traditional lecturing method for 8 sessions each
lasting 30 minutes. Data collection was done by a questionnaire including demographic
information and 50 questions of Medical Parasitology and Mycology given to the subject as class
quizzes, midterm exam, final exam and a test one month after the instruction sessions (25
questions were on taxonomy I, 15 ones on taxonomy II and 10 questions on taxonomy III).
Results: From 50 students, 30 ones (60%) were female and 20 ones (40%) were male. According
to the findings, both methods increased the level of knowledge significantly, but this increase was
more in discussion group comparing to the lecture group (P=0/002 and P=0/003).
Conclusion: The research findings show a higher rate of learning for group discussion method
that is due to the more efficacy of this method in promoting inter-group relations, brain-storming,
group-activity, group assimilation, and elevating level of judgment and analytic ability. Therefore,
this teaching method is suggested especially for teaching Medical Parasitology and Mycology.
