I used CaptureSpace to record an instructional video on how to graph inequalities with Desmos graphing calculator. I thought using CaptureSpace was a fairly straightforward process, which isn’t how I normally feel after using a program for the first time. I was easily able to record my video and upload it to the UP media page. In the future, I could see myself using a screencast to explain to students how to use technology, such as the Desmos graphing calculator or even certain functions on a Texas Instruments calculator. I could also use it show mathematical proofs for things that I don’t have time to prove in class. For example, if I want my students to know that the derivative of *sin(u)* is *cos(u)*, but I don’t have time to show a formal proof in class, I could give them access to a screencast of me proving it.

One thing I don’t like about screencasting is how difficult it can be to fix mistakes. For example, when I re-watched the embedded video, I realized that I made a mistake at the 1:33 mark – I said the circle had radius 4 when I meant to say that it had radius 2. This was a small mistake, so I just let it slide for the purposes of this assignment. However, if I was sharing a video with my students, I would not want them to be confused by a mistake on my part. Therefore, I would probably have to go back and re-shoot the entire video just to fix one mistake. And then if I noticed I made a mistake in the re-shoot, I might have to record yet again!
