讲评课作为一种课型是数学教学的重要方式,它能帮助学生重新认识知识、明确解题思路,从而达到查漏补缺、不断完善学生认知结构、建立解题模型的作用,还能培养学生的创新精神,提高分析问题、解决问题的能力。下面是我对一道题的讲评及个人的几点想法,期待其勉。一、无心插柳柳成荫——发现学生存在问题在一轮复习的范式中有一道试题:(2010芜湖中考题)如图所示,在圆⊙O内有折线OABC,其中OA=8,AB=12,∠A=∠B=
As a kind of class, teaching review class is an important way of mathematics teaching. It can help students to re-recognize knowledge and clarify problem-solving ideas so as to find out missing and missing students, improve students’ cognitive structure and establish problem solving model, Students’ innovative spirit, improve the ability to analyze and solve problems. Here is my comment on a question and a few personal ideas, looking forward to their encouragement. First, the unintentional Willow shade - found that students have problems in a round of review paradigm has a test: (2010 Wuhu test questions) as shown in the circle ⊙ O fold line OABC, where OA = 8, AB = 12, ∠A = ∠B =
