在数学教学改革的浪潮中,各种体现新理念的教学模式层出不穷,如何在这种形势下使课堂教学出新又出彩,使课堂充满活力和情趣,即让学生主动地探求、获取到知识,发展思维,增长能力,又在充满悬念和矛盾冲突的教学活动中,让学生领略到数学的魅力和威力,使教与学成为师生的一种共同享受,这是广大数学教师所努力追求的一种高境界.笔者在公开课“抛物线的概念和标准方程”的教学中完全打破传统的模式,进行大胆的尝试,取得了预期的效果,受到了学生和听课教师的好评.现将这节课教学过程中富有特色的部分介绍如下,并在后面进行必要的评析.
In the tide of mathematics teaching reform, all kinds of teaching modes embodying new concepts emerge one after another. How to make the classroom teaching new and outstanding in this situation, make the classroom full of vitality and fun, that is to enable students to actively explore and acquire knowledge, Development of thinking, growth, but also full of suspense and contradictions in the teaching activities, so that students appreciate the charm and power of mathematics, teaching and learning as a common enjoyment of teachers and students, which is the majority of math teachers to pursue A kind of high realm.The writer completely breaks the traditional pattern in the teaching of open class “the concept and standard equation of parabola ”, makes the bold attempt, has obtained the anticipated effect, receives the high praise from the student and the lecture teacher. The distinctive sections of the teaching process are described below, followed by the necessary comments.
