化学课尤其是实验课备受学生欢迎,但理论课往往缺少精彩的实验现象,如何让沉闷的化学理论课鲜活起来?首先就要从优化课堂问题设计上下功夫。下面就以高中化学第一册第二章第二节《气体摩尔体积》为例探讨一下如何优化问题设计。一、教学设计说明《气体摩尔体积》是本章及本册乃至整个高中化学的重要内容,在这一节内容的学习中,要建立两方面的知识:一是气体摩尔体积概念的建立;二是初步理解阿伏加德罗定律。二、教学实施过程 The chemistry class, especially the experimental class, is very popular with students. However, the theoretical class often lacks exciting experimental phenomena. How to make the boring chemistry theory class live? First of all, we must make great efforts to optimize the classroom problem design. The following high school chemistry to the first chapter second chapter second “gas molar volume” as an example to explore how to optimize the problem design. First, the teaching design description “gas molar volume” is an important part of this chapter and the entire high school chemistry and learning, in this section to learn, to establish two aspects of knowledge: First, the concept of gas molar volume established; second is Preliminary understanding of Avogadro’s law. Second, the implementation of teaching process
