Objectives : The purpose of this study was to examine what teaching behavior would have a good effect on learners in lecture-style instruction in the department of dental hygiene. Methods : The subjects in this study were 650 students who were in the three-year department of dental hygiene at four colleges in Gyeonggi Province and Chungcheong Province. After a survey was conducted, frequency analysis and ANOVA were utilized to analyze the collected data. The findings of the study were as follows. Results : The students put the highest value on knowledge among the factors of teaching behavior irrespective of their academic year, academic standing and learning style, followed by skills and attitude. Out of every subfactor, they set the highest value on a sense of humor regardless of their academic year, academic standing and learning style, and put the lowest value on the attitude factor such as enthusiasm. There were differences among the students in evaluation of the factors of teaching behavior according to academic year, and the students whose academic year was higher set a higher value on the factors of teaching behavior. There were no differences according to their academic standing and learning style. Conclusions : The dental hygiene students viewed the knowledge factor as the effective factor of teaching behavior, and regarded a sense of humor as the best subfactor. Although the attitude factor like enthusiasm is important, it seemed that the students hoped for the kind of instruction that would be delightful, intriguing and clearly convey what to learn.
