Abstract:Chemical experiment is a compulsory course for college chemistry. Due to limitations of teaching mode and other objective factorsꎬ traditional experimental teaching is not conducive to students′ innovative ability. With the development of information technologyꎬ virtual simulation technology are increasingly adopted in chemistry classesꎬ which can not only help students obtain consistent experience with real experiment teachingꎬ but also help to expand the breadth and depth of experiment teaching materialsꎬ thus improving the quality of experiment teaching and greatly contributing to the education goal of cultivating innovative talents. Its repeatabilityꎬ safety and innovation maximally make up the deficiencies of tradi ̄ tional experiment teaching and open up a new path for experiment teaching. In this paper we discuss our innovative teach ̄ ing reform from three aspects: teaching design ideaꎬ teaching design process and teaching effect analysis by taking the classic physical and chemical experiment of “the drawing of binary alloy phase diagram" as an example.
