物理是以实验为基础的科学,物理教学必须以实验为基础,以思维为中心.课标指出:初中物理实验“旨在让学生经历科学工作者进行的相似的探究过程,主动获取物理知识,领悟科学探究方法,发展科学探究能力,体验科学探究的乐趣,养成实事求是的科学态度和勇于创新的科学精神”.波利亚(美籍匈牙利数学家)说过,“在教一个科学的分支(或一个理论.一个概念)时,我们应该让孩子重蹈人类思想发展中的那种最关键的步子,当然我们不应该让他们重蹈过去的 Physics is experiment-based science, and physics teaching must be experiment-based and mind-centered.Coursebook states that ”junior high school physics experiment “ aims to enable students to go through the similar inquiry process conducted by scientists and take the initiative to acquire physical knowledge , Comprehend the methods of scientific inquiry, develop the ability of scientific inquiry, experience the pleasure of scientific inquiry, develop a scientific attitude of seeking truth from facts and a scientific spirit of innovation, ”said Polyglia (Hungarian mathematician of the United States)," teaching one The branch of science (or a theory, a concept), we should let the children follow the most crucial step in the development of human thought, of course, we should not let them repeat the past
