在新课改的实践中,科学探究是物理教学中的一个重要组成部分,在科学探究中如何进行猜想与假设对设计实验`进行实验起着导向作用.没有一个合理或着较为合理的猜想,势必使实验偏离正确的方向,得不出结论甚至得出错误结论 .因此在科学探究中有必要对如何进行猜想与假设进行一些探讨.一、猜想与假设在物理教学中的意义著名的物理学家爱因斯坦说过:“想象力比知识重要,因为知识是有限的,而想象力概括世界上的一切,推动着世界进步, In the practice of new curriculum reform, scientific inquiry is an important part of physics teaching, and it plays a guiding role in how to carry out experiments and experiments in scientific inquiry.Without a reasonable or reasonable conjecture, It is bound to make the experiment deviate from the correct direction, can not draw conclusions or even come to an erroneous conclusion.Therefore, in the scientific inquiry, it is necessary to make some discussion on how to make the conjecture and hypothesis.First, the conjecture and hypothesis in physics teachingThe famous physics Einstein said: ”Imagination is more important than knowledge because knowledge is limited, and imagination summarizes everything in the world and advances the world,
