摘　　要：基于建构主义理论和支架式教学思想,以"北京大学有机化学实验在线学习与测试平台"为依托,探索了混合教学模式在有机化学实验课程中的应用。以薄层色谱和柱色谱实验为例,通过确立目标、分析学情、分解任务、搭建支架、教学实施、评估反馈的教学设计和实践,帮助学生掌握实验知识与技术,培养学生解决实际问题的能力,增强其实验信心。Based on constructivism and scaffolding instruction,this study explored the application of blended teaching in organic chemistry experiment course with the support of"Peking University organic chemistry experiment online learning and testing platform".Taking the experiment of thin-layer chromatography and column chromatography as example,through the teaching design and practice of establishing objectives,analyzing learning situation,decomposing tasks,building scaffolding,teaching and feedback,students had a grasp of experimental knowledge and technology,acquired the ability to solve problems,and enhanced their experimental confidence.
