数学是研究模式和规律的科学。小学数学中探索规律的内容,主要是引领学生从身边事物之间的关系及变化入手,通过观察、思考、猜想、验证主动提出问题、发现规律。比较而言,探索规律的教学,学生的主体地位更加突出,自主性更加明显,个性化更加突出。扬州市育才小学东区校的于蓉老师、宝应县实验小学集团东校区李步良老师“多边形的内角和”一课的同课异构教学,在基于儿童的认知特点,构建互动生成平台,拓展数学思维空间,渗透数学思想方法的同时,又能创造性地使用教材,各有精妙构思,各取最佳
Mathematics is a science that studies patterns and laws. Primary mathematics to explore the contents of the law, mainly to lead the students from the relationship between things and changes in the start, through the observation, thinking, guess, verify the initiative to ask questions and discover the law. In comparison, to explore the law of teaching, the student’s subject status is more prominent, the autonomy is more obvious and the individualization is more outstanding. Yu Rong, an educator from East China School of Yucai Elementary School in Yangzhou City, Li Bu Liang from East Campus of Baoying Experimental Primary School Group, and Heterogeneous Teaching in the Same Class of Polygonal Inner Corner and Class, built an interactive platform based on children’s cognitive characteristics, Expand mathematical thinking space, infiltration of mathematical thinking methods, but also creative use of textbooks, each with its own exquisite ideas, each taking the best
