中学物理教学,不仅仅是把物理知识传授给学生,更重要的是要培养学生的学习物理的能力,使他们拥有敏捷的物理智慧,猜想和假设是物理智慧中最活跃的成分,对学生猜想能力的培养,是物理科学探究过程中的一个重要环节,也往往是教学过程中较难把握的难点。 Middle school physics teaching, not only to pass on the physical knowledge to students, more importantly, to develop students’ ability to learn physics, so that they have agile physical wisdom, conjecture and hypothesis is the most active component of physical intelligence, students guess The cultivation of abilities is an important link in the process of inquiry into physics science, and it is also often a difficult point in the teaching process.
