Abstract:
Student evaluations of teaching results have been used as an indicator of course success and instructor performance. Information obtained has been used to make course changes and improvements as well as to document instructor performance for annual performance evaluation and promotion and tenure packets. The purpose of this study was to develop a valid and reliable scale to assess student evaluation of teaching. The first phase of this study involved conceptualizing effective teaching. Effective teaching was operationalized with a Likert scale of 27 indicators. Face and content validity were assessed by a panel of experts. In the second phase, reliability and dimensionality were assessed. The target population was students enrolled in the College of Agriculture and Home Economics at New Mexico State University during the Fall 1997 semester. Inter-item consistency of the final summated scale of 27 indicators was determined with a Cronbach's alpha reliability of .97. Generalizability Theory was used to estimate the reliability for relative assessments on instructors or classes. Reliability assessments based on class size ranged from .80 to .96.
