“创设情境”是小学数学教学中常用的一种策略,它有利于解决数学中高度抽象性和小学生思维的具体形象性之间的矛盾,也是促使学生开展有效学习的有力手段。实施新课程以来,情境的创设和呈现,如同争奇斗艳的繁花,成为数学课堂中一道亮丽的风景线。但我们也会发现有些课堂看似热闹却少了数学味,学生沉醉在游 “Creating situation ” is a commonly used method in elementary mathematics teaching. It helps to solve the contradiction between the highly abstract mathematics and the concrete image of primary school students ’thinking. It is also a powerful means to promote students’ effective learning. Since the implementation of the new curriculum, the creation and presentation of the situation has become a beautiful landscape in mathematics classrooms. However, we also find that some classes are lively but less math-like, and students are immersed in the game
