从当前中学数学的实际情况来看,现在大家一致认识到,要进一步提高教学质量,必须加强基础知识教学和基本训练。所谓基本训练,我们的理解,是要在学生学好基础知识的前提下,培养他们运用这些知识解答问题的技能、技巧,以及应用这些知识解决实际问题的能力,更具体地说,主要是培养学生的计算、论证、绘图、测量等方面的技能技巧。基本训练与基础知识密切联系着,贯穿在整个数学教学的过程中,随着年级高低和教材内容的不同而有不同的重点和要求。例如代教式恒等变换,在初中阶段,主要是整式、分式的变换;而在高中代数里着重根式、指数式和对数式的变换,因而对学生的要求就要 From the current actual situation of middle school mathematics, now we all recognize that in order to further improve the quality of teaching, we must strengthen basic knowledge teaching and basic training. The so-called basic training, our understanding is that students learn the basics under the premise of training them to use these knowledge-solving skills, skills, and the ability to apply these knowledge to solve practical problems, more specifically, mainly to train students The calculation, demonstration, drawing, measurement and other aspects of skills and skills. Basic training and basic knowledge are closely linked throughout the entire process of mathematics teaching, with the different grades and textbooks have different priorities and requirements. For example, there are two types of equivalence transformations, such as integral and fractional transformation in junior high school, and roots, exponential and logarithmic transformation in high school algebra, so students' requirements are
