Abstract: 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.

Key words: General chemistry experiment, Dual-pathway blended, Integration of virtuality and reality
