From ethority, a great graphic, displaying and categorizing tons of popular Web 2.0 tools.
Wish I could have attended the Web 2.0 Smackdown session. Their collection of resourses in LiveBinder are amazing.
Present.me is an online tool where you can upload presentation and record video of you to accompany the presentation. A free account allows 10 recordings a month, each 15 minutes long.
Someone on Twitter shared a link to Kathy Schrock's, Infographics as Creative Assessment webpage. I have been intrigued by the cool infographics been virally spread across the social web and failed to see how getting students to create their own would create an opportunity for authentic learning and take the activity of collecting data to a whole new level.
Teacher's Domain - from their website "free digital media service for educational use from public broadcasting and its partners. You’ll find thousands of media resources, support materials, and tools for classroom lessons, individualized learning programs, and teacher professional learning communities."
And finally, I had email conversations with Doug Caldwell, eMINTS Instructional Specialist, about the awesome presentation he and Glen Westbroek made called When Students Think, They Remember. Their presentation was a model lesson that conference goers were able to participate in to experience an Inquiry-based lesson that utilizes the Intel's Visual Ranking Tool as well as other online resources.
