摘　　要：以探究铜离子与硫离子反应的多种可能性为贯穿线索,对人教版高中化学选择性必修1的重点知识进行复习。而针对复习课中存在着枯燥乏味以及容易忽视知识间的关联这一现象,采取主题式教学。本案例以提升学生问题解决的能力为目的,创设问题情境,使用创新型教具以及手持技术开展层层递进的实验探究,从而激发学生学习兴趣,加强知识之间的内在联系,培养学生的迁移意识。This article explored the various possibilities of the reaction between“Cu^(2+)and S^(2-)”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.

关 键 词：主题式教学 复习教学 手持技术 问题解决
