The study is to find out the effect of teacher-pupil interactive behavior in the course of dance teaching Lessons through CAFIAS system observing pattern. The study takes the Grade 2 students who select dance Lessons and the professional teachers of college dance Lessons in the South Taiwan as study objects. The study adopts observing research method, using CAFIAS observing record form of the teacher-pupil interactive behavior as its research tool. After the organization and analysis of data, we reach the following conclusions: (1) during the teaching of dance Lessons, teachers' behavior accounts for 61.02%; students' behavior accounts for 37.25%; other behaviors account for 1.73%; (2) for teachers' behavior: praise and encouragement account for 7.46% of teachers' behavior, which shows that teachers hold positive attitude toward students, and teachers are good at giving good feedback to students with praise and encouragement, which stimulates students well; (3) for students' behavior: expectable reaction accounts for 55.99% of students' behavior. Although the percentage is rather high, in light of the set and demand of the Lessons, in the course of teaching, students would like to reach a consensus with teachers. Leading by teachers, students are learning how to dance, while experiencing the fun of dance at the same time in the course of dance teaching, which makes teaching play a positive role in the interactive behavior.
