“细节决定成败。”教师所从事的课堂教学是一个动态生成的过程。许多教师过多地把精力集中在教学过程的预设、教学方法的选用和现代化教学媒体的使用上,而忽视了教学中的实效性这样使整个教学活动显得极不协调。下面就出现在数学课堂合作学习的实效性谈一谈自己的看法。“案例一”在小学数学“角的度量”的课堂教学中:教师要求每一个学生把课前准备好的两根硬纸条重合起来,并用钉子把他们的一端钉起来,然后旋转其中的一根形成大小不同的角。在这个
“The details determine the success or failure. ” Teachers in the classroom teaching is a dynamically generated process. Many teachers focus too much on the preconditions of the teaching process, the selection of teaching methods and the use of modern teaching media, while ignoring the effectiveness of teaching so that the entire teaching activities seem extremely uncoordinated. The following appears in the mathematics classroom cooperative learning effectiveness talk about their own views. Case Study 1 In primary school mathematics, “Measurement of the Angle” classroom instruction: the teacher asks each student to coincide the two strips of paper that are prepared beforehand and nail them to one end and then Rotate one of them to form a corner of a different size. at this
