新教材《数学》中的几何教学,与传统《数学》中的几何相比,虽然从演义推理转向了合理推理,淡化繁难的证明过程,但是,学习几何的目的还是没有改变,如发展学生的空间观念,训练学生的抽象思维、逻辑关系,以及条理表达等。由于诸多客观原因,致使我们的许多农村中学生在几何学习上感到一看就懂,一听就会,但唯独让他们运用起来就碰到困难, The geometry teaching in the new textbook “Mathematics” is compared with the geometry in the traditional “Mathematics”. Although the reasoning from reason to reason has been turned to reasonable reasoning and the tedious proof process has been diluted, the purpose of learning geometry has not changed, such as the development of students’ Concept of space, training students’ abstract thinking, logical relations, and expressions. Due to a number of objective reasons, many of our rural middle school students are able to understand and understand the geometry of learning. Once they hear it, they will find it difficult to use it alone.
