科学家G·波利亚曾说过,在科学研究中,猜想是合理的,是值得尊重的,是负责任的态度。物理猜想能缩短解决问题的时间;能获得物理发现的机会;能锻炼物理思维。因此,在物理教学中,运用猜想可以营造学习氛围,激起学生饱满的热情和积极的思维,培养学生克服困难的坚强意志,自始至终地主动参与物理知识探索的过程。猜想在物理教学中运用是重视科学探究的教育作用,强调过程和方法的学习,是探究学习的重要环节。
Scientist G. Polya once said that in scientific research, conjecture is reasonable, it is worthy of respect, and it is a responsible attitude. Physical guessing can shorten the time for solving problems; gain physical discovery opportunities; and exercise physical thinking. Therefore, in physics teaching, the use of conjecture can create a learning atmosphere, arouse students’ full enthusiasm and positive thinking, cultivate students’ strong will to overcome difficulties, and actively participate in the process of physical knowledge exploration from beginning to end. It is conjectured that the use of physics teaching is an educational function that emphasizes scientific inquiry, and emphasizes the learning of processes and methods. It is an important part of inquiry learning.
