“What's Everybody So Excited About?”: The Effects of Teacher Enthusiasm on Student Intrinsic Motivation and Vitality

Abstract Research on teacher behaviors that actively promote student intrinsic motivation to learn has been relatively scarce. In this article, 2 studies exploring the effects of teacher enthusiasm on both students' intrinsic motivation to learn and their pychological vitality are presented (Ryan & Frederick, 1997). In Study 1, a questionnaire including measures of intrinsic motivation, vitality, teacher enthusiasm, and numerous other positive teacher behaviors was administered to 93 college students. Among the teacher variables, enthusiasm was the most powerful unique predictor of students' intrinsic motivation and vitality. In Study 2, level of teacher enthusiasm (high vs. low) was manipulated in an experimental design with 60 college students. The students who received an enthusiastically delivered lecture subsequently reported greater intrinsic motivation regarding the lecture material and experienced higher levels of vitality. The authors speculate about possible mechanisms for and limitations to the positive motivational effects of teacher enthusiasm.
