数学是研究现实世界的空间形式和数量关系以及数学结构和模型的一门科学,它不仅具有逻辑的严密性、系统性、完整性等特点,而且还具有更为突出的纵横交错的互通性。在单元内容结束时,引导学生对单元内容进行系统的整理总结,对学生整体掌握知识、提高学生分析问题的能力及思维水平是非常必要的。因此,单元总结应是站在新的高度挖掘知识的内在联系及数学思想和方法的规律所在,应成为使学生在全面掌握知识的基础上学习和探索的继续。一、单元总结应使学生对本单元知识脉络清晰化理顺单元概念与概念,法则与法则,以及它们相互之间的 Mathematics is a science that studies the real-world spatial form and quantity relations and mathematical structures and models. It not only has the characteristics of logical rigor, systematicness and completeness, but also has more prominent crisscross interoperability. At the end of the unit content, guiding students to systematically organize and summarize the unit contents is very necessary for students to master knowledge and improve students’ ability and level of thinking to analyze problems. Therefore, the unit summary should be a new height to tap the inherent relationship between knowledge and mathematical ideas and methods where the law should be to enable students to fully grasp the basis of knowledge to learn and explore the continuation. First, the unit summary should enable students to clear the unit unit clear and smooth unit concepts and concepts, rules and laws, as well as between them
