牛顿曾经说过:“没有大胆的猜测,就不会有伟大的发现.”爱因斯坦也说过:“想象力比知识更重要,因为知识是有限的,而想象力概括着世界上的一切,推动着科学前进,并且是知识进化的源泉.严格地说,想象力是科学研究中的实在因素.”科学伟人的话对于今天开创事业的人无疑是十分有益的,对于明天改造世界的建设者——今天的中学生更为迫切.因为要想有所发现、有所发明、有所创造、有所进步,敢于走前人没走过的路,敢于做前人没做过的事,就离不开想象.猜想与假设,正是培养中学生想象力的有效途径.在物理教学中,我引导学生大胆猜想,通过“猜想——学习(修正或验证、补充、提高)——总结(知识并网)”的教学过程,收到了良好的效果.
Newton once said: “Without bold speculation, there will be no great discovery.” Einstein also said: “Imagination is more important than knowledge because knowledge is limited, and imagination sums up everything in the world. It promotes the advancement of science and is the source of knowledge evolution. Strictly speaking, imagination is the real factor in scientific research.” The words of the great man of science are undoubtedly very beneficial to those who start a business today, and to the builders who will transform the world tomorrow. —— Today’s middle school students are more urgent because they want to find, invent, create, and make progress. They dare to take the road that their predecessors have not gone through, and dare to do what their predecessors did not do. Imagination, conjecture and hypothesis are the effective ways to cultivate the imagination of middle school students. In physics teaching, I guide students to conjecture and conjecture, through “guessing-learning (correcting or verifying, supplementing, raising)-summarizing (knowledge and The ”net)" teaching process received good results.
