Abstract This article explored the various possibilities of the reaction between “Cu2+ and S2-” as a thread to review the key knowledge of selective compulsory one in senior high school chemistry of the People’s Education Press. In response to the phenomenon of being dull and easy to overlook the correlation between knowledge in the review class, a thematic series teaching approach was adopted. This example shows the aim of improving students’ problem-solving abilities, creating problem scenarios, using innovative teaching aids, and using handheld technologies to conduct progressive experimental explorations. Furthermore, this work can also stimulate students’ interest in learning, strengthen the connection between knowledge points, and cultivate students’ transfer awareness.
