There are two characters in the implementation of the university general education: One is the teacher; the other is the student. The issue caused by the teacher and students on the teaching site is an important factor affecting teaching efficiency. The humanity spirit can't be transmitted from one generation to another without the communication between the teacher and students in the general education. Therefore, based mostly on the teacher's practical action research and through a variety of observations and records of teaching activities, this paper hopes to be able to describe the harmony and conflict in the teacher-student interaction in the university general education, providing teachers with some improvements on the teaching of general education courses.In this action research, the researcher takes the course ”Multicultural Education” offered at I-Shou University as the research field and adopts the method of observation survey. Using the video recording of teaching, observation of activities, on-line interaction, students' inspirational thoughts homework, etc., two-time observational notes in two semesters are completed, and the encoding and analysis are also carried out. On the whole, from the key observations of ”class atmosphere”, ”teacher's attitudes towards students”, ”students' attitudes towards teacher”, ”class requirements interaction”, ”oral presentation interaction”, ”film appreciation interaction”, ”poster production interaction”, ”theme week workshops interaction”, ”group planning interaction”, ”field investigation interaction”, and so on, ten reflections are acquired and the contents could be used as references for the innovation in the future university general education.
