Abstract:The background is first given for the emergence of the teaching mode of“Direct, Explain, Comment, Practice & Ask” and then from the five aspects a systematic analysis is done to the structure of the teaching mode. The guiding principle is a shift from the teacher subject to the students subject, and the shift from four-centre mode of “textbook, teacher, teaching plan,classroom”to the two-center mode of “students and the learning plan”; and the learning method decides the teaching method, and the learning plan decides the teaching plan. Thus a new design of learning and teaching plan is put forth based on the teaching mode of “Direct,Explain,Comment,Practice & Ask” for the fulfillment of student-centered teaching philosophy and thus to train students' thinking, develop their abilities and enhance their moral sense in the teaching.
