我从事多年的数学教学中得出:初中几何证明题是学习的重点,又是难点。很多学生对几何证明题,不知从何做起,甚至部分同学表面上知道了答案,但叙述不清楚,说不出理由。对逻辑推理的过程几乎不会写,本来在我们山区大部分原来不愿学习数学的学生失去了学习的信心。2010年暑假,我有幸参加了参与式教学法的学习,并把自己学到的方法应用到实际教学中,结果得到了意想不到的效果。我的主要做法如下。一、让学生知道证明的本质是什么
I engaged in many years of mathematics teaching come to: junior high school geometry proof questions are the focus of learning, but also difficult. Many students on the geometric proof questions, I do not know where to start, and even some students on the surface know the answer, but the narrative is not clear, can not tell the reason. The process of logical reasoning is almost never written, and most students in our mountain area, who were originally unwilling to learn math, have lost their confidence in learning. During the summer of 2010, I was fortunate enough to participate in the participatory pedagogy and to apply the methods I learned to the actual teaching. The result was an unexpected result. My main approach is as follows. First, let students know what is the essence of proof
