中学化学练习中的“先行组织者”解析

On the“advanced organizer” of chemistry exercises in middle school

中学化学练习中经常有“先行组织者”模式的运用 ,特别是信息迁移题。解决化学组织者问题应该加强学生已有知识的清晰性和稳定性 ,针对不同的组织者类型采用不同的方法。练习中的组织者作用与一般的组织者稍有差别 ,主要是为了提高学生的理解能力和学习效果 ,强化学生的认知结构 。

The model of “advanced organizer” is often adopted in the chemistry exercises of middle school, especially in the question of information. To solve the organizer problem of chemistry, we should enhance the clarity and stability of what students have learned, and make use of different methods. The function of organizer in exercises is a little different from that of usual, which is mainly to improve students' comprehension and effectiveness, to enhance students' cognitive structure, and to promote keeping and migration of knowledge.
