平面几何这门学科在中学数学教学中占有重要的地位。学习它,对培养学生严密的逻辑推理能力,发展智力,提高分析问题和解决问题的能力,并带动其它学科的学习,有重要作用。 万事开头难,对平面几何来说,它在中学所有学科当中尤为突出。平面几何入门难,学生难学,老师难教,教学效果相对较差,这是众多教师、学生的共同感受。 Plane geometry This discipline occupies an important position in the teaching of mathematics in high school. Studying it plays an important role in cultivating students’ logical reasoning ability, developing intelligence, improving the ability of analyzing and solving problems, and bringing along the learning of other disciplines. Everything is hard at first, and for plane geometry it is particularly prominent in all secondary schools. Difficult to get into the plane geometry, students difficult to learn, teachers difficult to teach, teaching results are relatively poor, which is the common feeling of many teachers, students.
