新颁布的《数学课程标准》对学生自主学习提出了很高的要求,尤其要求放手给学生提供自主学习活动的时间和空间,这就要求教师在数学教学中,要善于抓住每一次机会生成课堂资源,创设有趣的情景,引导学生自主开展观察、实验、猜想、推导、讨论、交流等数学学习活动,让学生在活动中自主探索,在小组合作中学会探索和交流,在讨论交流中学会发现问题,总结经验,得出自己的结论,获取数学的能力。一、创设情境激发探究愿望 The newly promulgated “Mathematics Curriculum Standards” put forward very high requirements on students’ autonomous learning, in particular, they are required to give students time and space for independent learning activities, which requires that teachers should be good at grasping every chance generation in mathematics teaching Classroom resources, create interesting scenarios, and guide students to conduct their own mathematics learning activities such as observation, experiment, guess, derivation, discussion and exchange, so that students can explore independently in the activities, learn to explore and exchange in group cooperation, Discover problems, summarize experiences, draw your own conclusions, and acquire math. First, create a situation to stimulate the desire to explore
