This study tested the relationships among attitudes toward a course, instructor credibility, attraction, homophily, immediate recall, and student-teacher interaction. The major question explored how much variance of immediate recall and student-teacher interaction is attributable to course attitudes and instructor valence. Student grade point averages were used as a control. Two propositions were tested: (1) that dimensions of course attitudes, instructor credibility, attraction, and homophily are significantly related to immediate recall, and (2) that dimensions of course attitude, instructor credibility, attraction, and homophily are significantly related to student-teacher interaction. Involvement, competence, homophily, task attraction, and grade point averages were positively related to recall; social attraction was negatively related. Out-of-class information-seeking interaction between student and teacher was found to be positively related to involvement, character, extroversion, and social attraction, but negatively related to importance, competence, and homophily.
