王老师的这一节数学探索活动课,我认为有如下几个优点:一是由于充分发动了学生,发挥了合作交流在课堂探索活动中的大优势.利用了全班的合作交流,把标有“左”“右”“上”“下”“前”“后”的正方体纸盒的各种不同的展开图(以及后来的无盖正方体纸盒只有5个面的不同形状的展开图),一一展示了出来.也正是这一较全面的感性展示,为后面的教学奠定了良好的基础.二是关于正方体模型展开的5个研究性问题,充分显示了教师的充分准备、良苦用心与良好的业务水平.
In this section of the mathematics exploration activity of Teacher Wang, I think that there are several advantages: First, due to the full mobilization of students, they have played a major advantage in the cooperation in the classroom exploration activities. The use of the entire class of cooperation and exchange, the standard There are various unfolded drawings of the cube carton (as well as the following capless cube paper) with “left”“right”“”“”“before”“after” The box has only 5 sides of the different shapes of the unfolded map), which is displayed one by one. It is also this more comprehensive emotional display, which laid a good foundation for the later teaching. The second is the five studies on the development of the cube model. The question of sex fully shows the teacher’s full preparation, good intentions and good business level.
