摘要
在酸、碱、盐教学中以复分解反应条件教学为例,应用"微粒观"统领酸、碱、盐教学。基于"微粒观"构建了本节课的知识结构层级图,剖析了学生的认识发展过程,通过教学实践总结、归纳了若干教学策略,从而突破学生学习难点,提高学生的迁移和应用能力,并为高中进一步学习离子反应做好铺垫。
This paper applied particle concept to guide teaching of the conditions of double decomposition reaction, constructed the level diagram of related knowledge, analyzed the cogni-tive process of students. According to teaching practice, this study induced several teaching strat- egies to break the learning difficulties of students, improve studentsI ability of transfer and appli- cation of knowledge, and get ready for the study o{ ion reaction in senior high school.
