小学科学是以实验为基础的学科。精心设计实验,让学生通过亲自参加实验获得知识是搞好小学科学教学的关键。但是怎样才能让学生们在实验中有所启迪和收获呢?我认为首先要让学生懂得观察。伟大的生物学家达尔文曾说过:“我既没有突出的理解力,也没有过人的机智,只是在觉察那些稍纵即逝的事物并对其进行精细观察的能力上,我可能在众人之上。” Primary science is based on the experimental discipline. Careful design experiments, so that students get involved in the experiment to obtain knowledge is the key to improving primary science teaching. But how can we make students enlighten and reap the experiment? I think we should let the students understand the observation first. Darwin, the great biologist, once said: “I have neither prominent comprehension nor wittyness, but rather the ability to perceive and fleetly observe those fleeting things Above all. ”
