核心的数学问题,是一堂课的中心问题,它决定着我们研究的方向,提纲挈领。一堂课,核心问题的适时恰当的提出,更能促进学生参与学习研究,从而达到知识目标和能力目标的“共赢”。那么什么是核心问题呢?就是学生在研究的过程中所遇到的障碍和所需要解决的矛盾就是我们教学的核心问题。因此,在教学中,核心问题的设计可从两个方面来考虑:1储备具有弹性的核心数学问题,灵活应用,深度教学。2随机生成核心问题,培养思维的深刻性。在具体实施过程中,灵动而有弹性,因学生的生成而作恰当的调整。
The central problem of mathematics is the central issue of a lesson, which determines the direction of our study and its outline. A class, the core issues properly put forward at the right time, but also to promote students to participate in learning and research, so as to achieve the goal of knowledge and ability of “win-win.” So what is the core problem? Is the barrier encountered by students in the process of research and the contradictions to be solved is the core issue of our teaching. Therefore, in teaching, the design of the core issues can be considered from two aspects: 1 reserve flexible core mathematical problems, flexible application, in-depth teaching. 2 randomly generated core issues, develop the profound nature of thinking. In the specific implementation process, smart and flexible, due to students to make the appropriate adjustments.
