伽利略曾说过:“一切推理都必须从观察与实验得来。”对于小学科学来说,培养学生的想象力尤为关键。根据我个人的教学经历得出一个结论:实验设计事关教学成败。科学的实验设计方案有助于学生积极地学习基础知识、基本方法和基本技能,有利于新课标的实现与完成。但是,深入教学实践中去,我们会发现,有部分实验存在着这样或那样的不足,急须一线教师结合本校实际情况及时改进。在此,根据我多年执教科学的经验,简单谈 Galileo once said: “All reasoning must come from observation and experiment.” For primary science, it is especially crucial to cultivate students’ imagination. Based on my personal teaching experience, I come to the conclusion that the experimental design is about the success or failure of teaching. Scientific experimental design helps students to actively learn the basics, basic methods and basic skills, is conducive to the realization and completion of the new curriculum. However, in-depth teaching practice, we will find that there are some experiments there is such or that lack of urgent first-line teachers combined with the school’s actual situation in a timely manner to improve. Here, based on my years of teaching science experience, a brief talk
