高中数学课型构建与实例分析——以《直线与圆的位置关系》为例

Course Type Construction and Example Analysis:Take Positional Relation between Straight Line and Circle as an Example

目前高中课堂中的数学课型有概念课、评讲课、知识型课、习题课;选取知识型课为研究对象,从创设情境、引入新知,精选例题、巩固知识,变式迁移、拓展知识,总结方法、归纳知识,课后思考、升华知识这5个方面进行数学课型构建,打造高效的高中数学知识型课堂教学;通过高效的高中数学知识型课堂教学,提高数学课堂教学的效率,完成数学课堂教学目标。

With the promotion of a new round of curriculum reform and proposal of mathematics core attainment,how to construct highly-efficient classroom to boost all-round development of mathematical quality and capacity for high school students becomes very important.Currently,there are concept class,comment class,knowledge class,and excise class in mathematics class type for high school students.Mathematical course types are built in such five aspects as creating situation to introduce new knowledge,selecting examples to consolidate knowledge,variant transfer to expand knowledge,method summarization to generalize knowledge,and thinking after class to sublime knowledge so as to construct highly-efficient mathematics knowledge type classroom teaching for high school students.Mathematical classroom teaching efficiency is raised and mathematical classroom teaching goal is attained by highly-efficient knowledge type classroom teaching for the mathematics of high schools.
