我想就高三化学总复习课谈几个具体问题:(一)复习内容由于总复习时间短,按教学大纲规定只有十六课时,复习范围却包括全部高中教材,这些教材又是学生已学过的,这就给总复习课带来两个困难:(1)复习内容和时间有矛盾;(2)学生上复习课的积极性有问题。这些都要求教师慎重地考虑选择复习课的内容。教学大纲对总复习的要求是:按照元素周期表的分类来复习元素和它们的重要化合物。我认为这并不是说要在课堂上把各类元素又按教科书一样重述一遍,这样做时间上既不允许,学生也得不到多大好处。体会教学大纲的精神,我认为复习的重点应当是如何把全部高中教材用周期表、原子结构等理论知识来系统化,在理论知识的基础上加深认识,从而获得巩固的知识。
I would like to comment on the General Review of Senior Secondary Three several specific issues: (a) the content of the review due to the total review time is short, according to the syllabus only sixteen hours, the scope of the review includes all high school textbooks, these materials are students have learned , Which brings two difficulties to the general review: (1) there is a contradiction between the contents of the review and the time; (2) there is a problem with the enthusiasm of the students in the review class. These require teachers to carefully consider the choice of reviewing the content. The requirements of the syllabus for the general review are: to review the elements and their important compounds according to the classification of the periodic table of the elements. I do not think this is to say that we should restate all kinds of elements again in the classroom like a textbook. This will neither allow time nor benefit our students. Experience the spirit of the syllabus, I think the review should focus on how all high school textbooks with the periodic table, the atomic structure of the theoretical knowledge to systematize the theoretical knowledge based on a deeper understanding, in order to gain consolidated knowledge.
