This study quantitatively analyzed the educational effects of skill achievement through practice from the perspectives of both instructors and students.
The subjects were 62 students in the Department of Oral Health Sciences. Students self‐evaluated their achievement after sharpening Gracey curettes used for scaling and root planing, and the instructors evaluated students' achievement of the practice from the based blade morphology made after sharpening of the dull instruments by the students.
The average percentages for three items evaluated as "Satisfactory" by instructors was 66.0±22.5%, and the average percentage of four items self‐evaluated by students as "Can do" was 75.8±6.3%. In particular, in the instructors' evaluation, "Restoration of the angle and sharpness of the entire blade" was as few as 44%, while the student self‐evaluations were high overall. In addition, the number of students who answered "Can do" over the four practice sessions increased as session progressed with the fourth session increased significantly compared to the first session.
These results show that the addition of student evaluation to instructors' evaluation is effective in fostering students' independence and improving their motivation for learning. Further, the concerns of the practice were identified, and suggestion for the direction of the improvement for practice was provided. Shika Igaku (J Osaka Odontol Soc) 2022; Sep; 85(2): 99-105.
