摘要
选取“离子反应”知识作为研究内容,开展了相关化学数字化实验的教学实践,通过二段式测验工具、SOLO分类法的量化分析,来检测化学数字化实验对学生概念改变的影响.结果显示,化学数字化实验能够在一定程度上促进学生的概念改变.
This paper carried out the teaching practice of "ionic reaction" digital experiment,and used two-tier test tool and SOLO classification method to test its effect.The result showed that digital chemistry experiment could promote students’ conceptual change.
