摘要/Abstract

摘要： 为探究教学微视频播放速度对学习效果和学习满意度的影响，实验1采用行为测试和眼动追踪技术测查了62名大学生在正常播放、1.5倍和2倍播放条件下的学习效果和视觉注意过程。结果表明随着播放速度加快（1）学习者的学习效果和学习满意度会降低；（2）对图片区的注视时间及图文转换次数减少。加速播放视频不利于学习，可能是因为学习时长不同。从现实情境和理论研究两方面考虑，实验2控制了相等的视频学习时长后发现：（1）与正常速度相比1.5倍播放不会抑制学习，2倍播放的学习效果高于1.5倍；（2）但不同速度的学习满意度和眼动结果无显著差异。该研究为短视频播放速度的相关研究提供了新的研究视角，并对教学微视频设计提供了参照。

Abstract: In order to explore the effects of accelerating the playback of micro teaching video on learning performance and learning satisfaction, in Experiment 1, we used the retention test, transfer test and the eye movement tracking technique to measure the learning performance and the visual attention process. 62 college students were randomly distributed into normal play, 1.5 times of playing and 2 times of playing. The results showed that:(1) Accelerating playing micro teaching video hindersed learning performance and learning satisfaction; (2) With the acceleration of the playing speed, the fixation time of the picture AOI (Area of Interest) and the attention switches between text AOI and picture AOI were reduced. The reason why accelerating video playback was not conducive to learning might be that the length of learning was inconsistent. Considering the realistic situation and theoretical research, in Experiment 2 we controlled the learning length and found that:(1) Compared with normal speed, 1.5 times speed did not inhibit learning effect, the learning effect of 2 times speed playing was higher than 1.5 times speed; (2) There was no significant difference between the learning satisfaction and the eye movement among three different video playing speeds. This research has implications for the researches of the video playing speed, online learning and micro-video design.

Key words: micro teaching video, learning performance, learning satisfaction, time-compression, eye movement
