Neither the quality of teaching can be guaranteed, nor are students' thinking ability and innovation developed. To change this situation, many educators have done a lot of research and exploration from both theoretical and practical aspects, of which constructivist theory is one of main results. Constructivist theory emphasizes that leaming is a process of knowledge acquisition. Knowledge can not only get from teachers, but also requires learners to learn from others' help in some particular context, with the necessary leaming materials, and through a way of meaning construction. Besides, it has important reference and inspiration effects on discipline study and conducting educational research.展开更多
