Suppose you aren’t too happy with your previous assessment grades. Guess what? You can change them. All you have to do is show me you understand the material at a better level and I will change your grade.
How do you show this? The best way is to make a screen cast. This is essentially a recording of your computer screen. Here is an example.
You can use the screen cast with a worked out problem or a vpython program or something like that. How do you make a screen cast? I recommend using something free. There is of course Jing (http://www.techsmith.com/jing/). This is a program you download to run and make your screencast. You can then upload it and share it.
Another option is to use Screencast-O-Matic (http://www.screencast-o-matic.com/). This is another free screencast recorder, but it runs as a java applet. For the screencast-O-matic option, you would need to also upload your video to youtube. To do that, you will need to create a youtube account (free). When you upload it, you are welcome to set the viewing options to private or better yet “unlisted”.
If you set the video to unlisted, no one will be able to find it unless they have the address. Personally, I would just put it up there as public, but I know how some people are about putting up stuff.
After you upload a video, you need to have another student look at it and give the “thumbs up” to say it is ok. Then send me the link to the video and the name of the student that said it was ok.
Oh. There are other screen cast options out there. You are welcome to use what you like.
