一直以来,教学问题都是传统教学活动中的一项重要的教学内容,对于化学学科的特殊性而言,问题的设计成为学生知识结构构建以及解题能力发展的关键性环节.由此可见,化学教学中的问题设计具有着重要的实际意义.一、化学教学中主要的问题1.主题问题化学教学中的主题问题一般来说都是教学中的一级问题,一般来讲较为抽象,在解决这一类问题时,要对其进行分解,按照概念、理论、实验等分类,从不同的解决进行分析.由于主题问题有大有小,较大的主题问题需要在教学中安排较多的课时
All along, the teaching problems are all an important teaching content in the traditional teaching activities. For the particularity of the chemistry subject, the design of the questions becomes the key link in the construction of the students’ knowledge structure and the development of the ability to solve problems.Thus, The design of problems in chemistry teaching has important practical significance.Main topics in chemistry teaching 1.Thematic problems Thematic problems in chemistry teaching are generally a problem in teaching and are generally more abstract To solve this type of problem, we must break it down and classify it according to concepts, theories, experiments, etc., and analyze them from different solutions. Since there are some major and minor topics, the larger thematic problems need to be arranged more in the teaching class
