Search the web for some amazing Photoshop tutorials. Try a few out and expand your horizons. After you've tried a few, choose one that you would like to share with the class.
Using that project, create a tutorial of your own making. The idea being that you will use screen captures(see below) and easy to follow instructions to recreate the tutorial that you found online. Of course, you will improve the areas of the tutorial that you had difficulty with. We are also looking for something that can be completed in less than one class. No 5 hour marathon Photoshop sessions.
http://www.tutcast.com/ is a great place to start... as is YouTube. Too bad it's blocked!
Screen Capture - click on the start button -> in the search box type "snipping tool" -> use the snipping tool to take screen captures!
