一、拓展时空,提供自主探索的机会在数学知识的学习过程中,教师要给学生足够的探索时间和空间,为学生提供自主探索的机会,做到“学生能自己解决的,教师不提示;学生能自己思考的,教师不暗示;学生能自己评价的,教师不先表示”。例如,一位老师在教学“亿以内数的读写整理和复习”时,让学生自主整理这个单元所学的知识,先在小组内交流,各小组确定一个中心发言人,在全班作汇报交流,然后组织了一场答辩会,让学生自主提出问题,由中心发言人回答学生
First, to expand space and time to provide opportunities for independent exploration In the process of learning mathematical knowledge, teachers should give students enough time and space to explore, to provide students with opportunities for independent exploration, so that “students can solve their own, teachers do not prompt ; Students can think for themselves, the teacher does not imply; students can evaluate their own, teachers do not first said ”. For example, a teacher may ask students to organize their own knowledge of this unit while teaching “100% of reading, writing and reviewing.” Each group should first communicate within a group. Each group should identify a central spokesperson, For the exchange of reports, and then organized a reply to allow students to ask questions autonomously, the center spokesman answered students
