摘要
为全面深化信息技术与实验教学的融合,推进化学实验课堂的改革与创新,本文从信息化教学视角出发,借助虚拟仿真技术,开展了以"甘氨酸合铜的制备及其差热分析"为例的双线混融实验教学模式研究,实现了化学实验教学课堂从封闭到开放的转变,构建"过程-结果"二维度,"虚拟与真实、理论与操作、线上与线下"三结合,实施"课前网上预习-课中实验操作-课后总结分析"全过程的多元化实验教学评价方法,培养学生自主学习和实践探索能力,实现从预成性知识到建构性知识的转变.
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.
