一堂课上得好与不好,一条较重要的标准是是否达到了教学目的.如果教师对一堂课的目的,原来就不甚明确,那么,这堂课就将全部或部分地遭到失败.小数除法课例一位教师教学七册“小数除以整数”时,先复习旧课:①要学生背诵整数除法法则;②要学生板演2145÷15,并说出每步计算过程(怎样试商;怎样乘,怎样减……).然后新授,讲解48面上的例1.简要过程如下:(1)分辩.师问:这是什么除法?(包含除?等分除?)为什么?
A lesson is good and not good, a more important criterion is whether to achieve the purpose of teaching.If the teacher for the purpose of a lesson, the original is not very clear, then, this lesson will be in full or in part failed. Fractional division example A teacher teaching seven “decimal divided by the integer ”, review the old lesson: ① students to recite the law of integer division; ② students to board 2145 ÷ 15, and say each step of the calculation process How to multiply, how to reduce ...). And then the new grant to explain 48 examples on the face 1. Brief process is as follows: (1) to distinguish. Division Q: What is this division? )why?
