一、紧扣教材和大纲,重在夯实基础 作业布置必须建立在钻研大纲、教材和学生实际水平的基础之上。紧紧扣住大纲的要求,紧密结合双基选编习题,使用习题务必精选,资料越多越要精选,同时自编针对性强的补充习题,要紧紧围绕教材和教学大纲这一大方向,把着力点放在帮助学生打牢基础、促使学生提高能力上。例如,讲完“摩尔”这一概念后,课文中没有安排习题,我补充了以下思考题:1.在实际生产中,如果用“个数”来记录物质所含微粒的多少,有哪些缺点? 2.你学过哪些基本物理量?它们的基本单位是什么? 3.能否将物质的量理解为物质的质量、分子量?能否用物质的量来计量宏观物体的多少? 4.阿佛
1. Closely tie teaching materials and syllabus, lay emphasis on solid foundation The assignment of work must be based on the study outline, teaching materials and the actual level of students. The requirements of the outline are tightly bound, closely combined with double-basic selection exercises, and must be selected for the use of exercises. The more materials to be selected, the more appropriate the supplementary exercises should be. We will focus on helping students to lay a solid foundation and promote students’ ability to improve. For example, after the concept of “Moore” was finished, there were no exercises in the text. I added the following questions: 1. In the actual production, if the “number” is used to record the number of particles contained in a substance, what are the disadvantages? 2. What basic physical quantities have you studied? What are their basic units? 3. Can the amount of matter be understood as the quality and molecular weight of a substance? Can we measure the amount of a macroscopic object with the amount of a substance? 4. Aphrodite
