Study on Practical-teaching System of Environmental Sciences Based on the PBL Method

Abstract

After investigation and survey, the Practical-teaching System of Environmental Sciences in electric power universities had been reformed based on the problem-based learning(PBL) method. The improved PBL teaching model as " Problems posing + Information researching + Schemes designing and implementing + Evaluating (PPDE)" was set up and expounded in this paper. The PRDES model was carried out in practical-teaching system of Environmental Sciences in our university, and good results had been achieved.
