论文部分内容阅读
酸、碱、盐是初中化学中很重要的化合物,这部分的知识有如下特点:概念多、物质多、反应多、题型多、需记忆的多等,也是中考重点考查的知识点.学生往往学起来比较困难,因为对一类物质的学习,既要从组成和结构上认识这类物质的特点,又要认识这类物质的共性和每种物质的特性,怎样让学生系统掌握该部分知识,能灵活运用知识,以下是我在教学中的做法,请同行们指教并再完善.
Acid, alkali and salt are very important compounds in junior middle school chemistry. The knowledge of this part has the following characteristics: the concept is more, the substance is more, the reaction is more, the type of question is more, the memory is more, and so on, Often difficult to learn, because a class of material learning, both from the composition and structure of the understanding of the characteristics of such materials, but also to understand the commonalities of these materials and the characteristics of each material, how to make students grasp the part of the system Knowledge, can use the flexibility of knowledge, the following is my practice in teaching, please advise colleagues and then perfect.
