基于PBL的物理化学实验混合教学模式的设计与实践

doi:10.3866/PKU.DXHX202101059

Abstract

Abstract:

Based on the self-built online open course and internet teaching resources, the online and offline mixed teaching mode were carried out in physical chemistry laboratory. The "problem-based and student-centered" teaching processes were designed to carry out the inquiry learning and process evaluation. The students' abilities were trained stage by stage before, during and after class to improve their autonomous learning ability, comprehensive ability and innovation ability. The results achieved provide valuable experience for the exploration of online and offline mixed experimental teaching mode.

Key words: Problem-based learning method, Student-centered, Laboratory teaching, Mixed teaching
