Website Growth chart

This is a chart I ran across on the web in my research, showing the growth in the number of websites on the WWW. It's interesting for a couple of reasons:
  1. Because of the logartihmic setup, it looks like the growth in the number of sites is expected to slow in 2007. I think this is misleading, IF you don't pay attention to the left scale.
  2. Just think: 100 million websites online, and the web was only "invented" in the early 1990s. That is a LOT of information to search through. That's why it is IMPERATIVE that computer classes should teach search strategies, especially at the high school level.

Finally! Someone agrees with me re: Teaching Computers

Jakob Nielsen, in his Feb. 26th 2007 Alertbox article, deals with teaching computer skills. I have said for years that we don't need to be teaching buttons in computer classes - we need to be teaching processes. "Schools should teach deep, strategic computer insights that can't be learned from reading a manual." When I taught high school computers, my big frustration with all the texts we looked at was that they ALL were focused on buttons - click here to do this, click there to do that. So what were the kids to do when the user interface changed (as it ALWAYS does!)? Better to teach them how to think, how to learn, and the overall paradigms behind the basic comptuer tasks - word processing, spreadsheets, email, search, presentation design. nielsen adds one I hadn't though of - basic debugging. His point is that spreadsheets have errors, and you need to know how to go about figuring out how to fix them. I agree. The original article is here. Definitely worth reading!
