Exploration and Implementation of a Dual-Pathway Blended Teaching Model in General Chemistry Experiment Course:A Case Study of Copper Glycine Synthesis and Its Thermal Analysis
To deepen the integration of information technology and experimental teaching,and to advance the reform and innovation of chemical experiment instruction,this article employs virtual simulation technology to investigate a dual-pathway blended learning model,exemplified by the synthesis and differential thermal analysis of the copper glycine complex.This approach marks a shift in chemistry experiment teaching from a closed to an open model,establishing a two-dimensional framework of "process and outcome" and a tripartite integration of "virtual and real,theoretical and practical,online and offline" activities.It implements a diversified experimental teaching evaluation method through "pre-lab online preparation,in-lab experimental operation,and post-lab summary and analysis",fostering students'self-directed learning and exploratory skills.This method facilitates the transition from passive to constructive knowledge acquisition.
