认真研究《二次根式》一章,对于整个初中代数的教学都是很重要的。现就本章的教学,谈几点看法。一、重视对《二次根式》教与学的研究。《中学数学教学大纲》指出:通过本章教学,应使学生理解有关根式的一些概念,掌握它们的一些性质和运算法则,能熟练地进行二次根式的运算。教材安排的重点是二次根式的运算。《二次根式》一章,在整个初中代数中处于一个重要的地位,它既复习巩固了初一整式、分式运
A careful study of the “double root” chapter is important for the teaching of the entire junior high school algebra. Now on the teaching of this chapter, talk a few comments. First, attach importance to the “secondary root” teaching and learning. The Mathematics Syllabus for Secondary Schools states that teaching through this chapter should enable students to understand some of the concepts related to the root, grasp some of their properties and algorithms, and be proficient in performing quadratic root operations. Textbook arrangement is the focus of the second root operation. The “secondary root” chapter, which plays an important role in the entire junior high school algebra, not only reviews and consolidates the first monistic, fractional
