Outcome-based self-assessment on a team-teaching subject in the medical school

We attempted to investigate the reason why the students got a worse grade in gross anatomy and the way how we can improve upon the teaching method since there were gaps between teaching and learning under recently changed integration curriculum. General characteristics of students and exploratory factors to testify the validity were compared between year 2011 and 2012. Students were asked to complete a short survey with a Likert scale. The results were as follows: although the percentage of acceptable items was similar between professors, professor C preferred questions with adequate item discrimination and inappropriate item difficulty whereas professor Y preferred adequate item discrimination and appropriate item difficulty with statistical significance (P<0.01). The survey revealed that 26.5% of total students gave up the exam on gross anatomy of professor Y irrespective of years. These results suggested that students were affected by the corrected item difficulty rather than item discrimination in order to obtain academic achievement. Therefore, professors in a team-teaching subject should reach a consensus on an item difficulty with proper teaching methods.
