在传统的数学教学方法中,高中数学教师会以自己的教学思路为中心,告诉学生一个定义的概念、一个定理的内容、一个数学题的解答方法等。经过教学实践,人们发现学生的思维被限制在教师的教学范围以内。为了激发学生学习的潜力,人们要求教师以变式教学的方法激发学生的想象力、潜力以及创造力。本次以几个变式教学的实践案例说明高中数学教师要如何在课堂开展变式教学。一、应用开放题,让学生自己思考数学概念在传统的数学教学里,数学教师会讲述一些数学概念知识,
In the traditional mathematics teaching method, the high school mathematics teacher will use its own teaching idea as the center, telling the students a definition of the concept, the content of a theorem, a mathematics problem solution. After teaching practice, people find that students’ thinking is limited to the teacher’s teaching range. In order to stimulate the potential of students’ learning, people are demanding that teachers change the way they teach to inspire students’ imagination, potential and creativity. This time, several practical examples of variant teaching are used to illustrate how high school mathematics teachers need to develop variant teaching in the classroom. First, the application of open questions, so that students think about mathematics concepts in traditional mathematics teaching, mathematics teachers will tell some knowledge of mathematical concepts,
