Despite the effort to improve undergraduate education in China, "silence" in class, as a besetting sin, remains a puzzling problem for both teachers and students, who often ignore each other in class. This can be the result of teachers' negative attitude and inadequate competence in teaching. Furthermore, students' lack of enthusiasm, self‐ confidence and self‐control can also explain their silent presence in class. Finally, college students' silence can also be ascribed to the unreasonable school curriculum and the inadequate in‐job training on the part of the administrators. This article is intended to provide practical solutions to the silence‐related problems in college classrooms from the perspectives of teachers, students and schools in order to promote interactivity in class.
