1958年8月出版的高中化学課本第三册增加了氧化-还原反应一节教材。經驗証明,这节教材的增加,使学生对某些化学反应的实貭获得了較深的理解,对提高和巩固学生的化学知識起了一定作用。氧化-还原反应建立在原子結构和元素周期表等理論基础上。从学生旧有知識出发,学生接受氧化-还原反应这节教材,基本上没有多大困难。不过,我們仍须采用循序漸进,由浅到深的方法,按照課文順序讲述;在某些地方,也可作必要的加深。
August 1958 published in the third high school chemistry textbook added oxidation - reduction reaction textbook. Experience has proved that the increase of this section of teaching materials enables students to gain a deeper understanding of the realities of certain chemical reactions and plays a role in enhancing and consolidating students’ chemical knowledge. Oxidation - reduction reaction is based on the atomic structure and the periodic table theory. Starting from the old knowledge of students, students receive oxidation-reduction reaction of this textbook, basically no more difficult. However, we still have to adopt a step-by-step, shallow-to-deep approach in the order of texts. In some places, we can make the necessary deepening.
