新课程改革要求数学教学中开展变式教学,增强学生解决问题的能力。因此,初中数学教学中要设置变式教学情境;培养学生变式意识;提高学生应对变式问题的解决能力。几何画板是一种工具软件,它能够在数学课堂中发挥重要的作用,它可以有效地改善教学环境,激活数学教材内容,可以把静止的图形变得运动起来,可以准确测算并处理数据。它可以很好地适应新课改的初中数学教学要求,满足改善新课标的教学手段,实现初中数学变式教学。
The new curriculum reform calls for the development of variant teaching in mathematics teaching and enhances students’ ability to solve problems. Therefore, in the mathematics teaching of junior high school, it is necessary to set up a change teaching situation; cultivate student’s consciousness of change; and improve the ability of students to solve the problem of change. The Geometry Sketchpad is a tool software that can play an important role in the mathematics classroom. It can effectively improve the teaching environment, activate the content of the mathematics textbooks, and can move the static graphics into motion and can accurately measure and process the data. It can adapt well to the requirements of junior high school mathematics teaching for the new curriculum reform, satisfy the teaching methods for improving the new curriculum, and realize the mathematics teaching in junior middle school.
