The participants are eighty-eight university students. The action research collects the records of classroom activities and uses the Pre-service Teaching Beliefs Scale. The results show that digital teaching materials can help students understand the teaching environment, and the micro teaching way of teachers’ and students’ feedback enables students to know the problems of individual trial teaching. Students' learning engagement maintains a high degree of participation, and they hold high recognition for their professional knowledge and recognition.
