让学生在活动中享受实验——小组合作下的科学课外实验开展的策略初探

Let Students Enjoy Experiments in Activities: A Preliminary Study on Strategies to Carry out Science Extracurricular Experiments Based on Group Cooperation

初中科学学科属于实验学科,所以在教学中要对科学实验引起足够重视。但教师在实际教学中,要在有限的教学时间内提高初中学生的科学实验水平,确实不是件容易的事。近两年杭州市科学中考试卷中对实验内容考核的倾斜就体现了对实验的重视,实验又是农村中学学生的弱项。而小组合作下的课外实验,可以使教师更合理地把握有限的课堂时间,先学后教,以学定教,进而有效地提高初中学生的科学实验水平,丰富科学课堂的内涵。

Junior high school science is an experiment subject, so the teacher should pay sufficient attention to science experiments.But in actual teaching, it is difficult for the teacher to improve junior high school students＇ ability of scientific experiments in the limited teaching time. In recent years, more importance has been attached to experiments in scientific tests for senior high school entrance examinations in Hangzhou City, but rural junior high school students are weak in experiments. Extracurricular experiments based on group cooperation can help the teacher more rationally grasp the limited class time, so as to effectively improve students＇ level of science experiments and enrich the connotation of science class.
