摘要:AbstractThe Course Teaching Evaluation System (CTES) is a system which has been created to evaluate the quality of the teaching of courses in UKM. It is one of the student feedback systems which provide important input to continuously improve the quality of study programmes in all faculties. A study on UKM's CTES was conducted. The study focuses on the reliability of student feedback on CTES and the effectiveness of the system in revealing the effectiveness of teaching in a few predetermined aspects. The study was based on stratified random sampling of UKM students. The research methods used include observation made through eye tracker, questionnaire and interview. The research results would fulfil the main aims of the study, which are to explore whether the students have read the questions on CTES in detail before answering them and whether students give the questions sufficient thought and consideration before answering them. The findings would be used to determine the reliability of student input on CTES. The reliability of the feedback is very important in the quest to identify the effectiveness of teaching in the aspects of course content, infrastructure, equipment, laboratory and the teaching achievements of the lecturers.
