Since starting to teach LINC online, I have been introduced to a wonderful tool -- Screencast-o-matic. This amazing bit of technology is free, easy to use - and it does not require you to create an account. These are a few of my favourite things.
You begin by clicking the blue button "Start recording for free".
Next, you click the orange button "Launch free recorder" and wait for the recorder, consisting of a frame of dotted lines and a control panel, to appear.
You can move the frame around and resize it to capture the part of your screen you want to include in your screencast.
Once you have this in place, you just click the little red Record button, wait for the countdown, and begin speaking.
This handy tool is useful for making How-to videos for students. They can watch the video as many times as they want, pausing, rewinding, or fast forwarding if needed.
I have used this in combination with PowerPoint to create How-to videos for using VoiceThread, performing various operations in Google Drive, and for giving instructions on writing a paragraph.
It can also be used to show students how to use a website -- for example, how to create a student account on the ESL Library site.
With students who are quite tech-savvy, you could even assign a task of making their own screencast. My own students are not there yet, but maybe someday this will be a possibility for them
There is an optional upgrade, which some of my colleagues subscribe to. It is not expensive and allows you to make longer videos, as well as edit videos. In the free version, if you make a mistake, you need to start over, but if you have the paid version, you can edit your creations. So far I have not felt the need for the paid version, but perhaps in the future I will consider it.
If you haven't tried Screencast-o-matic, I recommend you visit the site and start creating.
