任何一个表面上看起来简单的问题,通过进一步思考,都可以挖掘出它很多方面的内涵.本文从人教A版必修1习题中的几个问题出发,进行课内外学生合作探究学习的尝试.一、通过寻求问题的多种解法来构建知识网络挖掘习题内涵.不仅能提高学生的思维能力,而且还能产生新的教学资源,同时也是教师专业成长的一个重要抓手.下面通过一道极其常见的三角函数问题的多种解法,来做由一题多解构建立体知识网络的尝试.
Anyone who looks simple on the surface can dig out many aspects of its connotation through further thinking.This article starts from the questions in the A-compulsory 1 -school to teach a lesson, and tries to explore the cooperation and exploration of the students in-class and outside the class. First, through the search for a variety of solutions to the problem to build knowledge network mining exercises connotation, not only can improve the thinking ability of students, but also generate new teaching resources, but also an important starting point for teachers’ professional growth.After an extremely common Of the trigonometric function of the multiple solutions to do more than one solution to build three-dimensional knowledge network attempt.
