Video has become an important part of higher education. 一些荟萃分析 显示技术可以促进学习(e).g.Schmid等人.， 2014)，以及多个 studies have shown that video, specifically, can be a highly effective educational 工具(e.g., Kay, 2012; Allen and Smith, 2012; Lloyd and Robertson, 2012; Rackaway, 2012; Hsin and Cigas, 2013).
Here is a quick look at what you will find in the below best practices for instructional 视频:
- Keep the video brief and targeted on learning objectives
- Use audio and visual elements to convey appropriate parts of an explanation; make 它们是互补的，而不是多余的
- Use signaling to highlight important ideas or concepts
- Use conversational, enthusiastic style to enhance engagement
- 在主动学习的环境中嵌入视频
Based on the premise that effective learning experiences minimize extraneous cognitive load, optimize germane cognitive load, and manage intrinsic cognitive load, we promote 三个有效的视频开发实践.
- Signaling, also known as cueing is the use of on screen text or symbols that highlight
重要信息.
- Examples: keywords on the screen, changes in color to emphasize information or relationships
- Segmenting is chunking of information to allow learners to engage with small pieces
of new information as well as give them control over the flow of new information.
- 例如:短视频(7-9分钟或更短)
- Weeding is the elimination of interesting but extraneous information from the video,
that is, the information that does not contribute to the learning goal.
- Examples: eliminating music, eliminate complex backgrounds
One of the most important aspects of creating instructional videos is to include elements 这有助于提高学生的参与度. 如果学生不看视频，他们 不能向他们学习吗.
Research shows that the median engagement time for videos less than six minutes long 接近100% (Guo et al., 2014). 9-12分钟的视频有50%的用户粘性 超过12分钟的视频参与度下降到20%.
提高学生参与度的建议:
- Use conversational style which promotes social partnership with the student
- 语速要快，要有热情
- Make sure the material feels like it is for these students in this class
To help students get the most of an educational video, it’s important we provide the tools to help them process the information and monitor their own understanding.
在你的视频中做到这一点的方法包括:
- 使用引导性问题
- Use interactive features that give students control
- 将问题整合到视频中
