数学基本活动经验作为新课程标准的“四基”之一,是数学课程内容的重要组成部分,也是数学课程生成和发展的基础。学生基本经验的获得依赖于多种学习活动,在教学中,我们可以通过观察、实践、猜想、建模、论证、应用等方式,“动”出操作经验,“悟”出思维经验,“寻”出探究经验,“用”出综合经验。 As one of the “four bases” of the new curriculum standard, the experience of basic activities of mathematics is an important part of the content of mathematics curriculum and also the basis for the generation and development of mathematics curriculum. The acquisition of students’ basic experience depends on a variety of learning activities. In teaching, we can “operate” out of operational experience through observation, practice, conjecture, modeling, demonstration, application, etc. Experience, “find ” out of the exploration experience, “use ” out of comprehensive experience.
