现行的九年制义务教育教材在初一就开设平面几何课，这一改革无疑分散了初中数学的教学难点，使过去的初二学生学习出现两极分化的现象得到缓解。由于学习几何需要一定的观察能力、思维能力，特别是逻辑思维能力，而初一学生年龄较小，学习几何有较大的困难。要培养他们学习几? The current nine-year compulsory education teaching materials set up plane geometry classes in the first year. This reform has undoubtedly dispersed the teaching difficulties of junior high school mathematics, and eased the phenomenon of polarization in the learning of students in the past. Because learning geometry requires a certain amount of observation ability, thinking ability, especially logical thinking ability, and junior students are younger, learning geometry has greater difficulties. How to train them to study?
