当前小学数学教学改革的热点之一是如何优化课堂教学,提高课堂教学效率。教学效率的高低主要看在一堂课内所达到的教学容量和实际效果。所谓教学容量,一是指教师在加强基础知识教学的同时,精心设计和安排训练项目,提高练的密度,达到培养能力和发展智力的目的;二是指教师能根据教学内容的内在联系和学生实际,增加一节课新授内容的输出量,使学生较完整地接受某一类知识,促使他们一开始就要多角度思考同类或类似知识的内涵和外延,训练思维的
One of the hot spots in the current reform of mathematics teaching in primary schools is how to optimize classroom teaching and improve the efficiency of classroom teaching. The level of teaching efficiency mainly depends on the teaching capacity and actual effect achieved in a class. The so-called teaching capacity, one refers to teachers in strengthening the teaching of basic knowledge at the same time, well-designed and arranged training programs to improve the practice of density, to cultivate the ability and development of intelligence purposes; the second is that teachers can be based on the intrinsic content of teaching and students In fact, increasing the amount of output of new lectures in a class enables students to receive a certain type of knowledge more completely, and enables them to think about the connotation and denotation of similar or similar knowledge from the very beginning and to train their thinking
