一、如何掌握教材的中心内容、中心思想在我们初步体会了教材的系统性、科学性、思想性、目的性,亦即掌握了教材的精神实质后,在这个基础上,我们进一步工作就是要分析掌握化学教材的中心内容、中心思想,我们从实际钻研过程中,初步认为掌握教材的中心内容、中心思想,主要的可分为下列两方面: (1)从单元教材中,或者一个课时的教材中,各节、各段都是围绕一个主要问题,而这个问题很明显地表现在某一节或者某一段的内客中。其馀各节、各段,有的是为阐明主要问题的基本知识,有的是这个主要问题的扩大加深、巩固或运用,最终都是为了形成一个完整的内容,这就是单元教材的中心内容了。
First, how to master the center of teaching materials, the central idea of our initial understanding of the teaching materials of the system, scientific, ideological, purpose, that mastered the material essence of the textbook, on this basis, we further work is to analyze Grasp the center of chemistry textbook content, the central idea, we actually learned from the process, initially that the master of the textbook center content, the main idea can be divided into the following two aspects: (1) from the unit textbook, or a textbook The sections and sections are all centered around a major problem, which is clearly manifested in a particular section or section of a guest.
