创新实验教学 培育学生探究能力——以透镜成像实验为例

Innovative Experimental Teaching, Cultivating Students’ Inquiry Abilities—Taking the Lens Imaging Experiment as an Example

摘要: “探究凸透镜的成像规律”是经典的光学实验，也是中学物理教学内容中的重点和难点。文章针对传统透镜成像实验演示过程中存在的问题以及学生对知识理解的偏差，对实验教具进行创新性的设计和改造。新型教具突破传统只能以静态图像呈现的效果，改为利用动态光源来演示透镜成像动态变化过程，能够更好地激发学生们的好奇心和学习兴趣，提供更直观、生动的学习体验，且为培育学生的科学探究能力提供了一种有效的工具和途径。

Abstract: “Exploring the Imaging Laws of Convex Lenses” was a classic optical experiment, and it was also a key and difficult point in middle school physics teaching content. Aiming at the problems existing in the demonstration process of traditional lens imaging experiments and students’ deviations in understanding knowledge, this paper carried out an innovative design and transformation of experimental teaching aids. The new teaching aid broke through the limitation that traditional teaching aids could only present static images. Instead, it used dynamic light sources to demonstrate the dynamic change process of lens imaging. This can better stimulate students’ curiosity and learning interest, provide a more intuitive and vivid learning experience, and also offer an effective tool and approach for cultivating students’ scientific inquiry abilities.
