【摘要】：成本是教学视频创作中必须考虑的因素之一。文章设计了教学内容完全相同、制作成本差异显著的两种教学视频:摄录式和录屏式。前者采用演播室摄录和后期编辑制作而成,后者采用PPT讲解和屏幕捕捉制作而成。40名大学生随机分为两组,自主观看任一类型的教学视频,随后完成保持测验、迁移测验、认知负荷自评以及学习满意度测量。统计结果表明:两组被试在各个观测指标上均无显著差异。事后访谈结果表明:两类教学视频各有优缺点。研究表明:高成本制作并不一定能显著改善教学视频的学习成绩和学习体验,文章据此对教学视频创作提出了一些建设性意见。
[Abstract]:Cost is one of the factors that must be considered in instructional video creation. This paper designs two kinds of teaching videos with the same teaching content and significant difference in production cost: video recording and screen recording. The former was made by studio recording and post editing, while the latter was made by PPT explanation and screen capture. 40 college students were randomly divided into two groups. They watched any kind of teaching video independently, and then completed the retention test and transfer test. Cognitive load self-assessment and learning satisfaction measurement. The statistical results showed that there was no significant difference between the two groups in each observation index. The results of the post-interview show that the two kinds of teaching videos have their own advantages and disadvantages. The research shows that the high cost production can not improve the learning achievement and learning experience of the teaching video significantly. Based on this, the paper puts forward some constructive suggestions to the teaching video creation.
