摘要：The quality of teaching and teacher plays a significant role in enhancing students’ cognitive and motivational development. The purpose of this study was to identify longitudinal trajectories of student perceptions of mathematics teachers’ professional competence, and to examine how these trajectories were related to students’ engagement and achievement in mathematics and their choice of college major. The data used for analysis were obtained from the Seoul Education Longitudinal Study, a study of 2714 secondary students who were followed up for five successive years. Results showed four heterogeneous trajectories of students’ perceptions of teacher competence, and these trajectories were associated with students’ engagement and achievement in mathematics. In addition, those who consistently perceived their mathematics teachers to be highly competent and whose perceptions of their teachers’ competence became more positive over time were more likely than other students to choose math-intensive majors. These findings imply longitudinal links between mathematics teachers’ professional competence as perceived by their students and students’ choice of college major as well as their engagement and achievement in mathematics.
