如何使网络教学有效教学视频

When preparing an online class, videos may be the first thing to come to mind. And, videos can be a great idea. However, you certainly do not want to transform your 50-minute lecture into a 50-minute video.

Instead, think carefully about your learning goals for each class session. And, think about which portions of your lecture class are best suited for video format.

你可以教不需要通过讲义,指定阅读,讨论板,播客和在线活动视频您的学习目标。(您可以检查出我的LMS网站上的部分examples。)

Once you’ve settled on a learning goal you think is well-suited for a short video, the first step is to do an online search to see if someone else has already made an excellent short video on the topic. There’s absolutely no need to reinvent the wheel. If you want to introduce a concept and there is a highly produced, scientifically accurate video freely available online, by all means, use that one.

(例如,我已经创建18 videos for teaching race and racism和you may find some of these useful instead of creating your own video that explains thedifference between race and ethnicity或者是什么racial formation theoryis.)

If, on the other hand, there is nothing available that conveys exactly what you’d like to teach, it’s time to make your own short video.

How to make own videos for teaching

制作视频教学可以很有趣,虽然制作高品质的视频需要大量的时间。我花了一年多,使这些18个视频,我有很多的帮助。这里有几个简单的步骤来使您的视频。

步骤1:福ite a script.
Your script should be between 100 and 500 words. It takes about one minute to read 100 words, so that will keep your videos at an ideal length of 1 to 5 minutes.

Step 2: Decide on the media for each sentence.
Look at each sentence in your script and decide on the best way to convey that sentence. There are at least four possibilities: 1) live-action; 2) still images; 3) slides with words; and 4) pre-recorded videos.

Our brains use two primary channels to take in information – audio and visual. We can use both channels simultaneously but can only take in input on one type of channel at a time. Both listening to and reading words are on the audio channel. So, we can listen to audio and look at an image. But, we can’t listen to audio and read words at the same time. Thus, if you show words on the screen, use the same ones you are speaking, and keep the words minimal.

第3步:创建一个故事板,影片中的每个句子指定介质。

我使用PowerPoint的我的故事板,但你应该使用什么技术是最简单的为您服务。有些人喜欢用Excel表格的故事板,例如。

Step 4: Start with still images.
There are tons of free images available on sites likepexels,unsplashFlickr的。您还可以在wikicommons找到历史图像。试图找到增值你在说什么的图像。如果你正在谈论的情感联系,例如,您可以显示一个母亲和孩子的照片。图像增强了消息。看看每一个句子,并决定是否可以使用图像来传达。

Step 5: Add in one or two pre-recorded videos
Pexels和其他网站也有提供免费的视频,你可以在录制你的声音。采用运动图像而不是静止图像可以保持观众的受理时间较长。也有可能是通过运动捕捉更好,如在水上船只的运动通过海路讨论移民的概念。

步骤6:在添加与滑动单词,短语,或是关键的数字。
您对他们只是幻灯片的话应该是最小的。但是,如果有一个定义,概念,句子或数字的学生需要看,包括与概念的幻灯片。

其包括定义和图像滑动的例子。

步骤7:包含一些真人
Live-action involves you speaking. When students see your face, it creates a human connection. So, having some live-action is useful. It can be a good idea to include some live-action at the beginning or in those places where you can’t find an image that works well.

应当清楚的是,制作好的视频花费了很多心思和时间。所以,只为您的类的影片,如果你已经确定你确实需要它们。否则,使用传达信息的替代方法。
