Psychometric Properties of an Instrument Developed to Assess Students’ Evaluation of Teaching in Higher Education

Abstract

Student evaluation of teaching is a global predominant practice in higher education institutions. Therefore, a major university in Jordan developed a questionnaire for students’ use in evaluating their instructors’ teaching effectiveness. Since student evaluation of teaching is an important process, the present study tried to examine the psychometric properties of the instrument. Item-total correlations showed acceptable internal consistency. In addition, a two-factor structure of the scale (teaching effectiveness and course attributes) was supported by exploratory factor analysis and confirmatory factor analysis from two independent samples. Convergent validity was supported by a moderate correlation coefficient between course averages of students’ ratings on the first factor and course averages of students’ final grades in each course. Finally, students’ responses on the factor that captures teaching effectiveness were found to have very high internal consistency (Cronbach’s alpha of 0.96). However, this instrument lacks evidences of content validity and convergent validity. Therefore, it is important to be cautious in evaluating faculty members and making promotion decisions that is based solely on the scores obtained using this instrument.
