学校教学工作的基本形式是課堂教学,因此我們貫徹基本生產技術教育,首先就要通过課堂教学使学生們自觉地獲得巩固的、深刻的化学基本知識,在这个基礎上使他們認識化学原理在工农業生產中的应用。同时,在課堂上我們还能够通过实驗來培养学生实际工作的技能和熟練技巧。在課堂教学中实施基本生產技術教育,我們的体会有如下兩点: 一、在課堂教学中必須首先教好基本化学知識,在这个基礎上來貫徹基本生產技術教育。因为学生們只有巩固而深刻地掌握了化学基本知識,才能有效地接受有关化学生產上的基本原理以及一系列的技術問題、生產組織問題。例如,在初中三年級講“鑄鉄的冶煉”一節,我們首先將鉄的物理性質、化学性質和冶煉鑄鉄的基本化学反应,講解透澈,使学生深刻地了
The basic form of school teaching is classroom teaching. Therefore, when we carry out basic production technology education, we must first make students consciously obtain consolidated and profound basic chemical knowledge through classroom teaching, and on this basis, let them recognize the principle of chemistry in the workers and peasants Industry production applications. In the meantime, in class, we can also experiment to develop students’ practical skills and skills. In the classroom teaching in the implementation of basic production technology education, our experience has the following two points: First, classroom teaching must first teach basic chemical knowledge, on this basis, to carry out basic production technology education. Only because students consolidate and profoundly master the basic knowledge of chemistry can they effectively accept the basic principles of chemical production and a series of technical problems and problems of production organization. For example, in the section entitled “Smelting of Cast Iron” in the third grade of junior high school, we first clarified the physical, chemical, and basic chemical reactions of cast iron,
