课堂导入,作为一堂课的首要环节,如能让学生印象深刻,无疑是迈开了成功的第一步。作为一名小学数学教师,笔者以为,我们应在较短的时间内使学生迅速地集中注意力,激发求知欲和思维活动,笔者经过多年的实践,有以下几点体会:一、直接导入直接导入是指教师直接将课题点出,从而引入新课的方式。如笔者教学《圆的周长》一课时,一上课,笔者便用简洁的语言说:“同学们,圆的半径、直径,你们已经认识了,那么圆的周长又是指什么呢?”有学生回答“:圆一周的长。”笔者接着让学生们请闭上眼睛进行想象,圆的 The introduction of the classroom, as the first part of a class, if impressed by the students, is undoubtedly the first step towards success. As a primary school mathematics teacher, I think, we should in a relatively short period of time so that students can quickly concentrate to stimulate curiosity and thinking activities, the author after many years of practice, the following experience: First, the direct import direct Import is the teacher points out the subject directly, thus introducing a new lesson. As the author teaching “circle circumference” a class, a class, the author will use simple language to say: “classmates, the radius of the circle, diameter, you already know, then what is the circle of perimeter? ”Some students answer “: Long week long. ”The author then let students close your eyes to imagine, round
