随着现代教育技术的广泛应用,课堂教学模式发生了质的变化,多媒体课件已经成为课堂的主流形态。诚然,多媒体课件的恰当运用,不仅活跃了课堂气氛,有时也大大提高了教学效率。但当我们倾心多媒体教学时,也不应对传统的教学模式嗤之以鼻。其实,在有些情况下,返璞归真,一支粉笔进课堂,充分利用好班级资源,同样也能创造精彩。现将笔者教学中一节“裸课”《素数与合数》(苏教版四年级数学下册)的教学流程辑录如下,与大家共同分享。一、导入师:同学们,前面我们学习了“因数和倍数”。大家还记得我们用什么方法研究和学习的吗? With the wide application of modern educational technology, the classroom teaching mode has undergone a qualitative change, and multimedia courseware has become the mainstream form of the classroom. Indeed, the proper use of multimedia courseware, not only active in the classroom atmosphere, and sometimes greatly improve teaching efficiency. However, we should not scoff at the traditional teaching mode when we focus on multimedia teaching. In fact, in some cases, back to nature, a chalk into the classroom, make full use of good class resources, the same can create wonderful. Now teaching a section “naked class ” “prime number and amalgam ” (Sujiao version of the fourth grade mathematics volume) teaching process is compiled as follows, to share with you. First, the import division: students, in front of us to learn “factor and multiple ”. We still remember what method we used to study and learn it?
