一节课40分钟,可以说分分钟都很珍贵,教师讲课的时间是多少,学生练习的密度有多大,也许很多教师都没有太关注这个数值,但教师能否科学合理的分配时间,节约每一分钟来提高课堂效率,是每一位教师都应该考虑的。在数学课堂上有两件物品对提高讲练密度与效率有极大的促进作用,一是便携式双面小黑板;二是活页习题纸。当然小黑板是针对条件比较落后的乡村学校。一般每节课要准备两块小黑板,在我们
A class of 40 minutes, minutes can be said to be precious, the teacher lectures time, how much the density of student practice, and perhaps many teachers are not too concerned about this value, but teachers can allocate the scientific and rational time savings One minute to improve classroom efficiency, every teacher should consider. There are two items in the math class to improve the density and efficiency of training has a great role in promoting, first, a portable double-sided small blackboard; the second loose-leaf exercise paper. Of course, the small blackboard is for the more backward conditions of rural schools. In general, we should prepare two small blackboards for each lesson
