Comparative Study of Objectively Structured Versus Traditional Viva-Voce in Microbiology amongst Second-Year MBBS Students

Abstract

to assess the difference in the marks obtained by students in traditional vivavoce (TVV) and objectively structured viva-voce (OSVV) examination formats and to evaluate the perception of students regarding OSVV. After obtaining institutional approvals and written informed consent, participating second-year MBBS students (n=62) were oriented about OSVV format. Assessment as per TVV format followed that using the OSVV format (both out of 20 marks) on the same day. Feedback comprising nine closed-ended questions (Likert scale) and one open-ended question was obtained from the participants. The marks obtained were statistically analysed and feedback was evaluated. While there was no significant difference (p=0.2357; Z=0.72), significant correlation (linear relationship; p<0.01, r=0.44) was observed between marks obtained in the two viva-voce formats. Majority of students were satisfied with OSVV in relation to syllabus coverage, duration for answering, relevancy of questions, avoidance of subjectivity/bias and fifty percent felt that difficulty level was well maintained. There was significant correlation between the marks obtained in the two formats of viva voce, though the participants preferred OSVV format.
