基于“视觉局限补偿”机理的 微视频设计模型——以初中物理“光现象”单元的学习为例

Micro-Video Resources Design Model Based on “Compensation for Visual Limitations” —A Case Study on the “Optics Phenomenon” Unit of Secondary School Physics

Two-tier diagnostic test regarding the Secondary School Physics topic of Optics Phenomenon was conducted on Grade 8 students. Results showed that learners’ visual limitations， especially the limitations on contrast sensitivity， time resolution and spatial resolution could lead them to obtain inaccurate or incomplete information. In order to change learners’ misconception from the source， this paper proposed a Micro-Video Resources Design Model Based on “Compensation for Visual Limitations”. Using this model， this study developed a series of micro-video resources regarding Optics Phenomenon. Quasi experimental study was conducted to test the model and the resources. The results confirmed significant improvements in the conceptual change of the experimental group compared to the control group.
