A twenty two itemed anonymous questionnaire on a five point Likert scale w a s administered to the students at the end of the course. Six perceived factors were extracted from the questionnaire using factor analysis. Results: There was a statistically significant difference (p<0.01 ) between the overall mean of PBL method compare d to the other methods of teaching. The perceived factor "communication with peers " had the highest mean score for PBL in both session s (4.5 7 + 0.5 8 and 4.0 9 + 0.9 3 respectively). However, PBL method was very helpful in all the six perceived factors while the students perceived that the traditional method of teaching was not helpful in "interaction with tutors" and "challenge to critical thinking". Conclusions: The findings showed that students preferred the PBL method to other forms of teaching .
