《初中物理课程标准》指出:在物理教学过程中,要让学生“尝试根据经验和已有的知识对问题的成因提出猜想,对探究的方向和可能出现的实验结果进行推测和假设”。科学探究既是学生的学习目标,又是重要的教学方式之一,而在科学探究的诸多步骤中,猜想这一步骤有着举足轻重的地位。牛顿曾经说过:“没有大胆的猜想,就不可能有伟大的发现。”猜想、推测和假设是根据现有的经验和知识,寻求对问题发生 “Junior Middle School Physics Curriculum Standard” points out that during the process of physics teaching, students should try to make conjecture on the cause of the problem based on experience and existing knowledge, to speculate and make assumptions about the direction of the inquiry and possible experimental results. . Scientific inquiry is not only the learning goal of students, but also one of the important teaching methods. In many steps of scientific inquiry, this step of conjecture plays a decisive role. Newton once said: “Without bold conjecture, there can be no great discovery.” "Conjecture, speculation and assumption are based on existing experience and knowledge, to seek the occurrence of the problem
