Abstract 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.
