【课例背景】《校园中的测量》“是新世纪小学数学三年级上册”数学好玩“版块中”综合实践“的内容。教材在设计上突出了”综合与实践“领域的典型特点:重问题、重过程、重综合,鼓励学生”从头到尾“地思考问题,活动最后还要”自我评价“。本节课我们主要设计四个活动环节:选择合适的测量工具;回顾测量方法;组织实地测量;反馈交流提升。下面以”选择合适的测量工具“和”反馈交流提升“为例谈谈在开展数学综合实践活动中如何凸显体验性与反思性。 【Case Background】 ”Measurement in Campus“ is the content of ”Comprehensive Practice“ in the third grade of elementary mathematics in the new century.Textbook is designed with ”Integrated and Practical“ ”The typical characteristics of the field: heavy problems, heavy process, re-synthesis, to encourage students to think about the problem from beginning to end, the event also Select the appropriate measurement tools; Review of measurement methods; Organize the field measurement; Feedback exchange to enhance. Below to “Select the appropriate measurement tools ” and “Feedback exchange to enhance ” as an example to talk about how to highlight the practice of mathematics Experiential and reflective.
