《普通高中物理新课程标准》指出:“通过多样化的教学方式,帮助学生学习物理知识与技能,培养其科学探究能力,使其逐步形成科学态度与科学精神”。通常探究式物理会以如下结构来实现这个理念:设置问题→提出假设→进行实验→观察现象→分析研究→抽出本质(规律)→得出结论。物理课要真正有效地开展探究,需要重视猜想和论证。所谓猜想就是 “Ordinary high school physics curriculum standards” pointed out: “through a variety of teaching methods to help students learn physics knowledge and skills, to develop their scientific inquiry capabilities, so that they gradually form a scientific attitude and scientific spirit ”. Usually the inquiry physics will realize this idea with the following structure: setting questions → making hypotheses → conducting experiments → observing phenomena → analyzing research → extracting essence (law) → drawing conclusions. Physics lessons need to focus on conjecture and argumentation in order to truly conduct inquiry. The so-called guess is
