The purpose of this study is to analyze the difference between the level of perform미1ce and the level of teaching competence according to teaching characteristics by using the Importance-Performance Analysis (IPA) technique and develop the instructional systems to enhance 따liversity professor s teaching competencies. Study 1 and 2 were conducted for this purpose. In Study 1, IPA questionnaires were given to professors at D University. Respondents were 155 and analyzed the data through descriptive statistics, t-test, borich value, and ANOVA As a result of the IPA questionnaire, the reqtrired level was statistically significantly higher than the execution level in all items of the teaching proficiency. This tendency was the same regardless of major field or lecture career, which means that most of the professors thought the presented teaching competence items are all important but did not implement it in their actual education. Based on these results, we have developed a common teaching system based on the proposed teaching competency items (content expertise, teaching design, teaching and learning promotion, evaluation, passion and respect for students) . Study 2 was conducted to create a concrete educational system for improving the teaching capacity of the professors of different colleges. We conducted focus group interviews to identify the needs for teaching competency support for each major. As a result of Study 2, we found that there is a very different educational needs for each 血ferent college. The conclusion of this study implies that the common teaching capacity support system for all professors and the teaching capacity support system for each college should be operated in a dual manner.
