Abstract:

A blended learning curriculum, Chemistry Laboratory Safety, has been constructed by the National Demonstration Center for Experimental Chemistry Education of Lanzhou University. Through the combination of online and offline teaching modes, the course which integrates safety training, virtual simulation learning, safety assessment and access certification has been established, and a three-dimensional, systematic and linked safety access information management system has also been established. It serves as an effective carrier for universities to carry out laboratory safety education and assessment. The students' safety values, the safety awareness of environmental protection, and the efficiency of experimental safety training are improved by the developing of the blended teaching mode, which has a positive effect on diversified and standardized safety education system.

Key words: Blended learning, Chemistry laboratory safety, Curriculum construction, Virtual chemistry experiment
