物理学是一门以实验为基础的科学,很多理论建立在实验的基础之上.“观察现象,进行演示和学生实验,能够使学生对物理事实获得具体、明确的认识,这是理解概念和规律的必要的基础.观察和实验对培养学生的观察和实验技能,培养实事求是的科学态度,引起学习兴趣,具有不可代替的重要作用.”对描绘简谐运动图像演示实验的改进,本文将从以下几方面说明.1该实验存在的不足现行教材中采用沙摆来描绘简谐运动的图像,
Physics is an experiment-based science. Many theories are based on experiments.“ Observing phenomena, demonstrating and student experiments can enable students to get a concrete and clear understanding of physical facts. This is the concept of understanding. The necessary foundation of laws and observations. Observations and experiments have an irreplaceable role in cultivating students’ observational and experimental skills, cultivating a scientific attitude of seeking truth from facts, and stimulating interest in learning.”Improvements in demonstrating simple harmonic image demonstration experiments, It will be explained from the following aspects.1 The deficiencies in the experiment The current textbook uses sand pendulums to depict images of harmonic motions.
