《义务教育数学课程标准》指出:培养学生的逻辑思维能力是中学教学目的之一。在平面几何教学中,经常是以学生对直观图形的形象思维和学生自身的直觉判断能力为基础,通过分析思维来检验判断结论的可靠性来达到对学生思维能力的培养。一、激活兴趣,诱导学生进行探索在初中几何教学过程中,几何图形的直观形象本身吸引着学生去了解图形所存在的内涵,而抽象思维所要求的严谨性往往使思维品质还不够健全的学生产生了畏惧心理。因此,我们可利用
“Compulsory education mathematics curriculum standards” pointed out: to develop students’ logical thinking ability is one of the secondary school teaching purposes. In plane geometry teaching, it is often based on students’ intuitionistic thinking of intuitionistic graphics and students’ ability of intuition to judge students’ thinking ability by analyzing the thinking to test the reliability of judgment conclusions. First, the activation of interest to induce students to explore Geometry in junior high school teaching process, the intuitive image of the geometry itself attracts students to understand the meaning of the existence of graphics, and abstract thinking requires the rigor of the quality of thinking is often not sound enough students Produced a fear. Therefore, we can use
