“综合与实践”作为一类以问题为载体、以学生自主参与为主的学习活动,如何实现数学教学的本真境界呢?下面笔者以《奇妙的图形密铺》的教学实践为例,谈几点思考。一、教学设计要真实真实,是对教学内在规律的把握。“综合与实践”是教师通过问题引领、学生全程参与、实践过程相对完整的学习活动,其教学设计既要关注问题的选择与展开过程、活动过程和结果的展示与评价等环节;又应根据不同学段学生的年龄特征和认知水平,根据学段目标,合理设计活动程序和学生 “Integration and Practice ” as a kind of learning activities based on problem-based and students’ independent participation, how to realize the true state of mathematics teaching? Talk about a few ponders. First, the teaching design to be true and true, is to grasp the inherent laws of teaching. “Integration and Practice ” is a learning activity that the teacher leads the question through the question, the student participates in the whole process, the practice process is relatively intact, its teaching design should not only pay attention to the choice and development process of the question, the activity course and the demonstration and evaluation of the result; Students should be based on the age characteristics of different segments and cognitive level, according to the objectives of the section, a reasonable design activity programs and students
