There are three purposes of this study: (1) to determine the degree of interaction between pupils and student teachers and teaching effectiveness as rated by pupils; (2) to determine the significance of difference of pupil ratings between those who express "more" and those who express "less interest" in the course taught by the student teacher whom they were asked to rate; and (3) to study other variables such as sex, age, and achievement in order to show how they relate to pupil and student teacher interaction.
