单元复习课是小学数学重要的课型,做好教学研究很重要。经实践,我们提出了单元复习课教学研究的路径模型:制定单元双向细目—整理知识要点示例—组卷与前测—设计教学活动。四大环节,环环相扣,首尾相连,互为因果,动态展开。下面以北师大版教材三年级上册第五单元的“周长”单元为例,阐述如下。 Unit review class is an important lesson in elementary mathematics, teaching and research is very important. In practice, we propose a path model for unit-based refresher teaching research: develop a two-way unit of cells-an example of tidying up knowledge points-test paper and pretest-design of teaching activities. Four major links, interlocking, end to end, mutual causation, dynamic start. The following to the Northern Normal University textbook third grade fifth unit “perimeter ” unit, for example, described below.
