4～8岁儿童溶解概念的转变

On the Conceptual Change of Solution of 4-8-year Children

本研究采用访谈法对南京市某幼儿园和某小学共90名4-8岁儿童的溶解概念进行研究。研究内容包括儿童对溶解现象的认识和儿童对“溶解”这一科学概念的认识。研究结果发现，儿童的科学概念是随着年龄的增长而发展的，不同思维发展阶段的儿童对溶解概念的理解呈现出不同的特点；儿童在解释溶解概念时经常混淆“溶化”与“融化”这两个概念；年龄越小的儿童越倾向于强调外力因素作用在溶解过程中的必要性。

The researcher conducted an interview on 90 4-8-year-old children in a kindergarten and a primary school in Nanjing regarding children＇s conceptual change of solution. The contents include children＇s understanding of the phenomenon and the scientific concept. The results show that children＇s scientific concept grows with age and children in different development stages demonstrate different features in their understanding of solution; children tend to confuse the concepts of dissolve and melt; younger children are more likely to emphasize the necessity of external force in the process of solution.
