在整个科学课堂教学过程中,一些表面看似微小、实质却重要的细节很容易被教师所忽视。然而,就是这些细节,不仅影响了科学探究的应有效果,而且妨碍了学生科学知识的获得和科学思维的发展,制约了学生科学素养的全面提高。一、钻研教材不透彻,字词偏差致失误在“空气占据一定空间”一课“杯底的纸不湿”教学环节中有如下片断:师:把一团纸巾塞入一个杯子里,然后将杯子倒着插入水槽内的水中,你们认为纸巾会被浸湿吗?
In the entire process of teaching science, some seemingly minor, real but important details can easily be overlooked by teachers. However, these details not only affect the due effect of scientific inquiry, but also hinder the students ’access to scientific knowledge and the development of scientific thinking, which restrict the overall improvement of students’ scientific literacy. First, studying the text is not thorough, the word error caused errors in the “air occupy a certain space ” a lesson “the bottom of the paper is not wet ” teaching section has the following pieces: Teacher: a group of tissue into a cup , Then pour the cup back into the water in the sink, do you think the tissue will be wet?
