This study verified whether educational psychology courses are effective in improving the teaching competence and subject-specific competence of university students. In addition, it was investigated whether the effects of educational psychology classes differed according to school types, i.e. elementary and secondary pre-service teachers, college, and general university students.
To this end, pre- and post-tests were conducted for students who took the educational psychology courses for one semester. As a result, it was confirmed that the educational psychology courses were effective in enhancing students' teaching competence and subject-specific competence, but there was no significant difference by school types. Additionally, it was found that there was a significant correlation between the teaching competencies and the subject-specific competencies, which means that teaching educational psychology can cultivate both competencies. This study suggests that the importance of educational psychology courses should be recognized in teacher education curriculum.
