在一次教学能手比赛中,几位选手上了相同的一课《常见的材料》。三位选手不约而同地设计了一个相同的教学环节:让学生在教室里选择自己感兴趣的材料进行研究、感知。而在三次探究活动中学生又不约而同地对教室里银幕表面的材料产生了兴趣,有许多学生围着银幕议论着:这是用什么材料做的昵?面对这相同的教学环节,三位老师作出了不同的处理。 In a teaching contest, several players took the same lesson “Common Materials.” The three players invariably designed a similar teaching session: let students choose their own interesting materials in the classroom for research, perception. In the three inquiry activities, students spontaneously expressed interest in the material of the screen in the classroom. Many students discussed the screen: What kind of material did they use? In response to this same teaching process, the three teachers made Different treatment.
