有效讲座视频的六个技巧

Looking for ways to create effective lecture videos? 这里有六个有用的建议:

• 技巧1:编写脚本    

  • Research shows that the time spent in synchronous online or in-person class sessions is best used to discuss, clarify, analyze or expand upon the lecture's content. Creating lecture videos for asynchronous homework assignments opens up that valuable live class session time.

• 技巧2:保持视频简短

  • Research shows short (3-5 minute) videos are best as they lessen cognitive overload 而且更容易被消化. Plus, many students learn-on-the-go and these micro-lesson videos can be viewed in between activities, work commitments, or family duties.

    In the article, 有效的教育视频 you'll find an overview of Cognitive Load Theory, The Cognitive Theory of Multimedia 学习和建议.

    The second half of the article, starting with "Student Engagement" outlines concise, research based tips for creating interactive videos that engage students (5 min read, begin half way down page on “Student Engagement”).

• Tip #3: Speak like you're having a Conversation  

  • Keep your tone similar to the tone you use in front of the class.

    Look straight into the camera to mimic eye contact. 这将有助于建立联系 你和你的观众之间.

    在整个视频中提问. You can build these questions into your script and pause briefly for students to think about them. 或者在录制完视频之后， you can add questions that pop up on the screen using Canvas Studio注解.

    您还可以考虑创建一个 帆布工作室视频测验 for a low-stakes self-check or small homework assignment.

• 技巧4:计划重复使用视频

  • If you plan to use the video again, avoid saying the date/semester/year.

    It may seem simple, but it's not always easy to remember. 要避免“slip-up”，请使用 一份计划你要说什么的稿子. 

    Also, avoid referring to current events, too. 

• 提示5:总是添加标题

  • Including edited/corrected captions in all videos you share is one way to adhere to 可访问性标准. It is an essential step as it aligns with 联邦和州法律以及犯罪现场调查组的政策.

    It is highly recommended to request captions using Canvas Studio. 在Canvas Studio上创建标题 (3 minutes).

    You can also use YouTube的自动字幕 feature but the captions aren't as correct as Canvas Studio's, so it is more time 消费更正标题.

    All captions must be edited (corrected) to adhere to 可访问性标准.

• Tip #6: Provide Transcripts and Options to Listen to Audio Only

  • Think of the variety of ways students view course content whether it be while commuting on a noisy bus, while washing dishes, running on the treadmill or studying in a location 与低带宽. Giving them options to access the content is essential.

    创建记录: 

    A transcript can be used to quickly search for specific points in the lecture and supports those who benefit from reading the content.

    If you create a script for your videos, share it as a transcript using a Google Doc, Word, or PDF file. 

    If you don't have a script and you used Canvas Studio, you can download the Canvas Studio captions file as a text-only version of your video.

    

    If using Zoom to record, you can share the Zoom transcript with your recording. 

    

    提供音频文件:

    If you use Camtasia, you can create audio files. Here's how: Export the video file as audio only (M4A).
