بررسی پایایی ابزار ارزشیابی کیفیت آموزش استادان

Abstract Background and purpose: Teaching evaluation questionnaire of instructors is an important instrument used in educational processes which can be performed using different methods including students' feedbacks. This is now considered as a challenging educational issue and different positions exist in this regard. The purpose of this study was to assess the reliability of students' feedback in different terms and majors in the evaluation of instructors teaching the same course. Materials and methods: In a cross-sectional analytic study, evaluation of 40 instructors was carried out by 89 groups of students. Each instructor was teaching a specific course to several groups of students. The questionnaire was classified into four areas. The total score was assessed for each instructor and analyzed using descriptive statistics and correlation test. Reliability was assessed by Cronbach's alpha coefficient. Results: The reliability of the questionnaire was high (α=0.96) based on Cronbach's alpha coefficient. The reliability index was the highest in the area of teaching skills (α=0.96) and the lowest in terms of educational discipline (α=0.81). There was a significant correlation among different studied variables scored by different groups of students for each instructor. A significant correlation was also found between the total and the average score (P<0.001). Conclusion: The questionnaire used for the evaluation of the instructors was highly reliable and reliability was higher than optimal level in all areas. Therefore, it seems that students' feedback is one of the reliable methods in the evaluation of instructors using an appropriate questionnaire.
