延展性问题就是指通过具体的问题和教学活动使学生在已有知识基础上,依据性质和程度的不同体验变化结果。数学教学必须依据学生的不同需求而进行,让学生适应问题的现实性、开放性,获得多种答案或多种解法,推广、扩充或迁移知识。数学学习过程中注重问题设计,把原问题进行延伸拓展,转化新知识、拓宽解题思路、培养和发展创新能力,为其学习的持续发展提供保证。
The problem of ductility refers to the fact that students can experience the changes based on the existing knowledge and on the basis of their differences in nature and extent through specific problems and teaching activities. Mathematics teaching must be based on the different needs of students, so that students adapt to the reality of the problem, open, access to multiple answers or multiple solutions, promotion, expansion or migration of knowledge. In the course of mathematics learning, we pay attention to problem design, extend and expand the original problems, transform new knowledge, broaden the way of solving problems, cultivate and develop innovative ability, and provide guarantee for the sustainable development of learning.
