Comparison of Student Performance, Self-mutual and Tutor Teaching Assessments in PBL Tutorial Process Between 1st and 4th Year Dental Undergraduates

Abstract Objectives: Evaluate the effectiveness of PBL teaching and analyze potential influencing factors between senior and junior from the perspectives of student performance, student self-mutual and tutor teaching evaluations.Results: Study found the overall three comparative assessments scores of Grade 4 were significantly higher than those of Grade 1(P＜0.01). Further analysis revealed no significant difference of student performance score between Grade 4 and Grade 1 in the 1st unit (P＞0.05), but it was improved and maintained significantly since 2nd time (P＜0.01).Moreover, each self-mutual evaluation of 4th year students was significantly higher than that of 1st year students, especially in the second half of the course (P＜0.01).And, all the evaluations of tutor teaching from seniors were significantly higher than those from juniors (P＜0.01). Finally, no significant correlation between student self-mutual scores and those given by tutors no matter high or lower grade (P＞0.05).
