一、问题思考的起点在《普通高中数学新课程标准(实验)》中,总共有两次提到螺旋上升.第一次是在分析必修1时提出的:像函数这样的核心概念需要多次接触、反复体会、螺旋上升,逐步加深理解,才能真正掌握,灵活应用.第二次提到则是在讲到各部分内容关系时说的:…还要注意明确相关内容在不同模块中的要求及其前后联系,注意使学生在已有知识的基础上螺旋上
First, the starting point for problem-solving In the “general high school mathematics new curriculum standards (experiment),” a total of two times referred to the spiral rise.First time in the analysis of compulsory 1 proposed: the core concepts like functions need multiple Contact, repeated experience, the spiral rise, and gradually deepen understanding, in order to truly grasp and flexible application of the second reference is talking about the relationship between the various parts of the content: ... but also pay attention to clear the relevant content in different modules And before and after the link, pay attention to make students on the basis of existing knowledge spiral
