开始学习平面几何,绝大部分同学兴趣很浓,决心学好,雄心很大。过了一段时间却出现两极分化。究其原因,是学生在思维能力,特别是逻辑思维能力上的差异。寻求解决,要改进教学,改进教学的重点是紧紧抓住逻辑思维能力的培养。一、早做准备平面几何的教学任务,一是研究平面图形的性质,二是培养逻辑思维能力。用推理论证的方法研究图形的性质,而逻辑思维能力是推理论证能力的基础。对推理论证能力的培养,课本上采取长期酝酿逐步解 Began to learn plane geometry, most of the students are very interested in, determined to learn, great ambition. After a while, there was polarization. The reason is students’ differences in thinking ability, especially logical thinking ability. In order to solve the problem, it is necessary to improve teaching and improve the focus of teaching is to firmly grasp the cultivation of logical thinking. First, early preparations for plane geometry teaching tasks, one is to study the nature of graphic graphics, the second is to develop logical thinking ability. The nature of the graph is studied using the method of inferential reasoning, and the logical thinking ability is the basis for the theoretical competence. To develop the ability to promote theoretical evidence, textbooks adopt long-term brewing and gradual solutions.
