初学平面几何,涉及平面几何证明,不知从何下手是初二学生学习平面几何反映较为突出的普遍性问题,是初中数学教学中的一大难点。平面几何证明,不仅要求学生全面正确地掌握所学过的定义、公理、定理及表达方式等,还要能够根据给定的已知条件,掌握探索证明结论的过程方法与思维习惯。因此,教师在教学过程中要坚持注重对平面几何证明思维方法的培养和严格训练,促进学生养成良好的思维习惯,从而提高平面几何证明教学效果与质量。
Beginning plane geometry, geometric plane related to proof, I do not know where to start is a fundamental two-dimensional plane geometry reflects the more prominent issue of universal, junior high school mathematics teaching is a major difficulty. The proof of plane geometry not only requires students to fully grasp the definitions, axioms, theorems and expressions they have learned, but also be able to master the process and thinking habit of exploring and proving the conclusion according to given known conditions. Therefore, in the process of teaching, teachers should insist on focusing on the training and rigorous training on the method of thinking of plane geometry to promote students to develop good habits of thinking so as to improve the teaching effect and quality of plane geometry proof.
