Moreover, it increased both student-student interaction and teacher-student interaction in and out of classroom, promoted critical thinking, expanded teaching time and space. All these made our teaching being more attractive to students. PAD class is good for strengthening the connotation-oriented development of higher education which focus on the improvement of teaching and leaning quality.
