The major purpose of this study is to investigate the changes in student teachers' sustainable volition for learning before and after practice teaching, especially in relation to the changes in their teacher efficacy and the self-evaluation of their own practice teaching. In terms of the content of their university course, the study focused on the following two areas in order to examine the student teachers' sustainable volition for learning: (1) theoretical content, such as psychology; and (2) more practical content, such as instructional skills. One hundred and thirty four student teachers completed a questionnaire in the study. Major findings are as follows: (1) student teachers who increased their teacher efficacy for instructional strategies and classroom management after practice teaching increased their sustainable volition for theoretical learning, such as instructional methods for school subjects and the study of pedagogy; student teachers who decreased their teacher efficacy in these areas similarly decreased their sustainable volition for theoretical learning; (2) student teachers who showed more negative self-evaluation in relation to lesson planning and preparation decreased their sustainable volition for practical learning, such as instructional skills.
