The saying that sooner or later the online world will replace teachers just might become true....nah, not really. But Virtual Nerd might just be the closest thing to the end of teachers...at least Math and Science. Virtual Nerd is a site that students and teachers can use to help teach content in math and science. Currently there are only tutorials for Algebra I, but they are working at adding some more.
You can get a basic account (Free) and have access to a dozen or so tutorials. Or you can get a premium account (paid - $49 a month) and have access to all the tutorials. They advertise in their opening video that tutors can be expensive, true, but a great teacher will be a virtual nerd for free. Besides, 600 a year is a lot of money considering most people who need such help probably can't afford it.
The tutorials are rather neat and they do allow for a lot of interaction and hands on help. If you know most of the steps you can easily skip to the one you need help with. It also organizes the tutorials in a neat fashion. To get a better idea of the software, just visit Virtual Nerd and watch the video intro to see some of the features. You can find the Algebra topics that are covered here
