高中化学可视化教学实践探索

Explorating the Practice of Visualization in High School Chemistry Teaching

高中化学可视化教学利用现代信息技术和信息资源,以知识可视化和思维可视化为手段,将抽象、隐形、复杂的知识内容具体化、显性化、形象化,有利于发展学生化学核心素养,并促进信息技术与化学课程的深度融合。基于此,文章以高中化学“电解质”的相关内容为教学背景,设计了运用导电测试仪、手持技术和思维导图三种不同形式的可视化课堂教学,以期实现技术与教学的深度融合,探索高中化学课堂教学可视化的途径和效果。

Visualization in high school chemistry teaching uses modern information technology and information resources to make abstract,invisible and complex knowledge content concrete,explicit and visualized by means of knowledge visualization and thinking visualization.It is conducive to the requirements for the development of students’chemistry core literacy,and pro⁃motes the deep integration of information technology and chemistry curriculum.Based on this,this paper takes the relevant con⁃tent of“electrolyte”as the basis of classroom teaching,and designs three different forms of visualization in classroom teaching by using conductivity tester,handheld technology and mind mapping in order to achieve the deep integration of technology and teach⁃ing and explore the ways and effects of visualization in high school chemistry classroom teaching.
