Student/instructor attitude similarity, student ratings, and course performance.

Investigated the validity of student ratings of instructional effectiveness by exploring the relations among student ratings, course performance, and the perceived attitude similarity of students and their instructors. 349 college students enrolled in 22 classes first rated instructor effectiveness on a 28-item rating form and then rated their own attitudes plus instructor attitudes on an attitude scale adapted from D. Byrne (1971). Another 296 college students enrolled in 19 classes rated instructor effectiveness and then their own attitudes plus instructor attitudes on an attitude scale adapted from F. E. Hofman and L. Kremer (see record 1980-33352-001). For both S groups, official end-of-term grades were also collected. Consistent with prior research, modest correlations were found between student ratings and perceived attitude similarity. There was also a modest relation between similarity and course grades. These relations were greatly reduced (56.2 and 44.5%, respectively) when the large influence of instructors on ratings and achievement was removed. Findings fail to support the claim that perceived attitude similarity is a substantial source of bias in student ratings. (13 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)
