教师对学生的观察、实验指导要适度,如果指导得过于具体,先观察什么,后观察什么,一切规定死,结论虽不会错,但学生收获了什么就很难讲了。我决心改变这种状况。在教《种子里面有什么》一课时,我要求学生自选种子,自己设计条件,做种子萌发的实验,同时做好观察记录。 Teachers observe the students, the experimental guidance should be moderate, if the guidance is too specific, what to observe first, what to observe, all the provisions die, although the conclusion is not wrong, but what the students harvested it is difficult to say. I am determined to change this situation. In teaching “What’s in the seeds?”, I asked the students to choose their own seeds, design their own conditions, and experiment on germination of seeds. At the same time, they should keep a good record of observation.
