在很多研究课、比赛课、展示课中,我们经常看到老师们为了一堂课大动干戈,什么课前谈话、游戏,什么多媒体展示,什么情景创设等等。我们不能一概否定这些,但充斥其中的“多余的谈话”“没有必要的多媒体”“为了精彩而精彩的情境创设”实在是太多了。没有这些我们就不能教数学了吗?没有这些我们就不能讲高效了吗?简单教学,不是一概地舍弃。一方面,学校的教学硬件(特别是农村学校)较差,所谓简单教学就是教学研究部门要考虑现实的教学条件,研究在缺乏硬件环 In many research class, competition class and exhibition class, we often see teachers go for a lesson, talk before class, games, what kind of multimedia display, what scene creation and so on. We can not deny it all, but there is so much “excess talk,” “unnecessary multimedia,” “creating for wonderful and exciting situations.” Without these we can not teach math? Without these we can not speak efficient? Simple teaching, not always give up. On the one hand, the school’s teaching hardware (especially rural schools) is poor, the so-called simple teaching is the teaching and research departments to consider the reality of teaching conditions, the study in the absence of hardware ring
