荷兰著名数学家、教育家弗洛登塔尔教授曾指出:“反思是数学思维活动的核心和动力。”由此可见,反思的重要性。一堂课45分钟,课时少、任务重的情况下,教师怎样利用有限的时间让学生轻松掌握所学知识,实现高效课堂呢?笔者带着这样的疑问,进行了以下两个方面的教学实践,取得了较好的教学效果。一、注重对例题教学的反思(一)一题多解,发散思维在讲解例题时,我们教师不能只求数量,片面追求速度,不能对问题进行拓展,不善于帮助学生理解数学问题的本质。这样的
Prof. Florenthal, a famous Dutch mathematician and educator, once pointed out: “Reflection is the core and motivation of mathematical thinking activities.” Thus, the importance of reflection. Lesson hours, heavy tasks, teachers how to use a limited time for students to easily grasp the knowledge, to achieve efficient classroom? I with such questions, conducted the following two aspects of teaching practice, Achieved good teaching results. First, focus on the reflection of the sample teaching (A) a solution to multiple solutions, divergent thinking Explaining the sample, we teachers can not only seek quantity, one-sided pursuit of speed, can not expand the problem, not good at helping students understand the nature of mathematical problems. Such
