Enhancing teaching effectiveness by using the Six-Sigma DMAIC model

As the competition increases in higher education, how to improve teaching quality to promote educational performance becomes a significant issue. Many higher educational institutions (HEIs) make efforts to establish a feedback system to monitor and reflect the outcomes of teaching evaluations. This study aimed to describe the use of the Six-Sigma DMAIC (Define, Measure, Analyse, Improve, and Control) procedures and the Importance-Performance Analysis (IPA) method to implement a feedback system step by step. The study proposed some useful instruments to illustrate how evaluations of teaching can be simple and objective by using a questionnaire, how to detect the disadvantages on teaching, and the decision strategy to prioritise disadvantages that are in need of corrective action. HEIs may use these instruments to establish an effective feedback system.
