Why would you integrate Web 2.0 tools in your classroom?
Make units, lessons, or assessments that you do in class better
Increase student engagement
Model responsible and ethical behaviors using technology
Increase the resources available to you
One more tool to add to the toolbox
Should I completely redo everything I do to add Web 2.0 in my classroom? NO, don't view technology or Web 2.0 as a replacement for what you do. The technology fit should make sense. Students can see when something is forced and unnatural. Start with something small with a lesson or unit that you know can be made better.
