The Verification of Reliability and Validity of Shimonoseki City University Lecturer Evaluation Scale (SLES)

Lecturer evaluation by students is one of the methods that are likely to provide important information in evaluating the “quality” of education. However, the current situation is that it is being promoted without investigation of reliability and validity. The purpose of this study is to verify the reliability, content validity, and construct validity of Shimonoseki city university Lecturer Evaluation Scale (SLES), which is a lecturer evaluation by students. The subjects were 1,286 students in the freshman to senior of economics. SLES is a comprehensive scale can be applied to three types of lectures: face-to-face lecture, simultaneous bidirectional lecture, and on-demand lecture. The reliability was verified using Cronbach’ s α co efficient, and construct validity was verified using structural equation modeling. As a result of the analysis, the reliability was 0.912 for the face-to-face type, 0.930 for the simultaneous bidirectional type, and 0.919 for the on-demand type. In terms of construct validity, a high degree of suitability was shown in all lecture form. This study suggests that SLES can be used effectively with undergraduate students. and on-demand lectures. Further investigation with large samples with larger sample size is recommended.
