科学课堂中,不论是猜想假设环节还是实验探究环节,都离不开交流。讨论交流也是科学教师喜欢采用的一种教学方式。在有些时候,从表面上看学生交流得很热烈,课堂气氛很活跃,仔细观察会发现,大家都在各说各的,没有对所讨论的问题达成共识。有的看似在交流,实际上他们的交流更像是在聊天,没有解决实际问题。下面我就从以下几个细节谈谈如何提高科学课堂交流的实效性。一、合理分工,有序交流首先,要根据学生实际情况进行分组,基本做到各组实力相 In the science classroom, both the hypothetical hypothetical link and the experimental link are inseparable from communication. Discussions and exchanges are also a teaching method that science teachers like to adopt. On some occasions, on the surface, the students exchanged warmly and the classroom atmosphere was very active. Careful observation revealed that everyone was speaking different and did not reach consensus on the issues discussed. Some seemingly communicate, in fact, their exchange is more like chatting, did not solve practical problems. Here I will talk about how to improve the effectiveness of science exchange in the following details. First, a reasonable division of labor, orderly exchange First of all, according to the actual situation of students grouping, basically the strength of each group phase
