I will be teaching Computer Applications next school year and will be using a relatively ancient computer lab. I believe most of the computers are G3 iMac and Powermac 5000-series. Also, there will be a small number (maybe 3 or 4) new Dells (but, I will be trying to trade those for G4s). My question is: What can I use these things for? Bear in mind that there is a 100% chance that they probably have only about 64 MB of RAM (if that!). Basically, I am free to teach whatever the heck I want. I was thinking about a simple online typing program, which I can monitor in real-time (http://www.learn2type.com/) and maybe some website that allows me to teach simple HTML and have the students create a webpage or website. Also, registering them through blogger.com to create an online journal is another idea. I am very chummy with the school's CNS (Computer Network Specialist), so I can ask favors.
