Implementing problem-based learning in an online class

Abstract

This paper studies learning based on constructivism, PBL (problem based learning) and dialectic relations between subjects and objects, and gives explanations to the strategy of guidance on problem-based online class. By using comparative study, this paper discusses the strategies and contents of teacher's guidance in the context of online class, and practices the strategies and contents. The results demonstrate that if the strategies of guidance are appropriate, subject consciousness of students can be improved, as well as their participation in the class, so the class becomes more active. Meanwhile, the teacher for online class should be more competent in information knowledge, design and control of class than in traditional class.
