可视化教学手段在物理实验教学中应用

Application of Visualization in Physics Experiment Teaching

根据脑科学的“双重编码”理论,可视化是一种发挥大脑视觉认知能力与空间计算能力的思维系统。在物理实验教学中应用物理演示实验、摄像同步教学的可视化教学手段,探讨可视化在物理实验教学中的效果。在教学实践中以声速测量实验为例开展研究,对周四上课学生采用演示实验和摄像同步教学,利用问题前测后测的方式反馈实验效果,并在实验后进行问卷调查;对周一上课学生未采用可视化教学手段,按照常规上课。从前测与后测问题反馈情况和学生调查问卷统计情况以及对照组实验最终成绩差异可以看出,合理使用可视化教学手段能促进物理实验教学效果,并得到学生普遍认可,表明这种可视化教学手段具有推广意义。

Based on the“double coding”theory of brain science,visualization is a thinking system that gives play to the visual cognitive ability and spatial computing ability of the brain.This paper discusses the effect of visualization in physical experiment teaching by applying visual teaching means such as demonstration experiment and video synchronous teaching in physical experiment teaching.In the teaching practice,the sound velocity measurement experiment is taken as an example to carry out the research.On Thursday,demonstration experiment and video synchronous teaching are used for students.The experiment effect is fed back by the way of pre-test and post-test questions,and a questionnaire survey is conducted after the experiment.On Monday,visual teaching means is not used for students,and the regular class is followed.It can be seen from the feedback of pre-test and post test questions,the statistics of questionnaires and the the final scores of the control group’s experiments that the proper use of visual teaching means can promote the teaching effect of physical experiments,which is widely recognized by students,and that this visual teaching means is worth promoting.
