初级中学数学课本《代数》第二册,经过修订,将于1984年春季开始,供初中一年级下学期的学生使用,每周5课时。本书在修订过程中,吸收了几年来各地在试用原通用教材中的意见和经验,对原通用教材作了一些改进,特别是注意加强分析能力的培养和易教易学。一、注意加强分析能力的培养学生在学习数学基础知识、解决数学问题和实际问题时,或多或少都需要一个分析过程。尤其在解决实际问题时,需要运用分析的方法,把一个实际问题化为数学模型,弄清它的全部结构,把它分解成一个个基本的数学问题并分别加以解决(以便运用综合的方法求得整个问题的答案)。这种分析能力的强弱,与学生对基础知识的掌握程度有密切的关系,能力必须以一定的知识作为基础,同时它又是理解和掌握知识快慢、难易的一种重要因素。学生进入中学学习后,智
The second volume of algebra, the junior high school mathematics textbook, has been revised and will be available in the spring of 1984 for students in the next semester of the first grade of junior high school, 5 hours per week. In the course of revision, the book has absorbed opinions and experiences from various places in the trial of the original general textbooks for several years, and made some improvements to the original general textbooks, especially to strengthen the cultivation of analytical abilities and educating and learning. First, pay attention to strengthen the analysis of the ability to develop students in the basics of learning mathematics, solving mathematical problems and practical problems, more or less need an analysis process. Especially when solving practical problems, it is necessary to use analytical methods to turn a practical problem into a mathematical model, clarify its overall structure, and decompose it into basic mathematical problems and solve them separately (in order to apply a comprehensive approach Get the answer to the whole question). This strength of analysis has a close relationship with students’ mastery of basic knowledge. The ability must be based on a certain amount of knowledge. At the same time, it is an important factor in understanding and grasping the speed and difficulty of knowledge. After entering middle school, students
