Chunkit.com by Tiger Logic is an interesting tool: it opens two windows side by side and offers annotations on search results with the intent of cutting down on the use of commerical web sites for research. It does require a download, but visit the web site and watch the tutorial video for more information.
Splashup.com (formerly known as fauxto) is online freeware for the person who needs photoshop on the fly. It’s a robust program for free.
We discussed alternatives to Powerpoint such as Slide.com (blocked by DPS filters) Moblyng.com Comiqs.com to make visual presentations more interesting. Of course Voicethread was an option as were animoto and Google Presentations. (See examples of TJ’s voicethreads and animoto videos on the Tj web site)
Google Apps have proven to be a popular and easy tool for classroom teaching and collaborating.
