演示实验作为一种课堂上最主要的实验形式,其科学探究功能亟待开发。文章通过在一节课上的实验教学设计提供三条可行的开发思路,即在演示实验中培养条件控制意识、推广对比实验思路和形成工业生产模型,每个设计都是在课堂上简单可行的。
Demonstration experiment is one of the most important experimental forms in the classroom, and its scientific inquiry function needs to be developed. The article provides three feasible development ideas through the experimental teaching design in a class, that is, to cultivate awareness of condition control, promote the comparison of experimental ideas, and form an industrial production model in the demonstration experiment. Each design is simple and feasible in the classroom.
