Abstract It is important to understand what teaching attributes a teacher will develop or improve in high priority, and what in low priority? Importance-performance analysis (IPA) offers a simple, yet useful method for simultaneously considering both the importance-performance dimensions when evaluating or defining attributes. The study applies IPA to evaluate teaching attributes in a junior college in Taiwan. For above, a mathematics teaching is as an example. In the case study, a student satisfaction questionnaire was surveyed and 185 students were asked to respond. The performance for each attribute in the survey can be computed by the mean value, while the importance for each attribute was evaluated by the variance-based methods. Then, a four-quadrant importance-performance map can be used to offer the teacher and his manager how they develop and improve their teaching attributes.
