This study explores phenomenologically the experiences of college of education students who participated in the semester practicum. In this study, we analyzed the experiences of 11 students who participated in the semester practicum. From the phenomenological research method of Giorgi, this study found five themes, 16 categories, and 152 semantic units through in-depth interviews. The five dimensions are 1) the expectation of educational practice, 2) the experience of social relationships, 3) the parallel study and practice that is becoming saturated, 4) the effort to enhance professionalism, and 5) the pride of having completed practice and worriedness about the future. The participants felt difficulties controlling students and preparing for classes because of a lack of instructional skills during educational practice. However, they understood the duties of teachers, including teachers' duties and administrative tasks. In addition, they experienced school curriculum implementation, a teacher's attitude and responsibility, and the teaching profession's value. This study is meaningful because it understands the experience of semester practicum and raises social and policy interest in them.
