As most teachers will be able to tell you, there are an amazing number of web-based resources available online.
Many teachers think a significant challenge to making use of different software is learning how to use them. I disagree that is our biggest challenge. Through experience I have found many similarities among software applications, and most students intuitively learn their way around web-based software quite quickly. I think all we need to do as teachers is help (most) students find the medium, and they will be able to figure out how to use it to communicate with us!
The bigger challenge, I have always felt, is staying up to date with what applications are out there. It seems like every week I read about a new tool, or someone shares one with me. I frequently find myself thinking/worrying that I might be missing something important...UNTIL NOW.
Today, I happened across what appears to be a very comprehensive collection of web 2.0 tools for teachers, all in one place. Thanks to Jesper Isakkson for putting this together! I've added it to my delicious bookmarks, and I hope it comes in handy for some of you too! A screenshot showing the list of categories is at the beginning of this post.
As comprehensive as this map is, I have not seem some of my favorites on the list. One that is missing is www.dipity.com. If you have students create timelines in your classes, perhaps some may find the option of making their timeline online appealing? Here is a link to my favorite 11 year old blogger's most recent assignment in social studies, created using dipity: http://www.dipity.com/SuperMrgolf12009
