Google

Learning aid support tools that are available to learn productivity software are: video tutorials, web quests, websites, and audiotapes

The productivity software I am going to focus on is Google Drive. Google has a large selection of applications for educators. The ones I use most are Google Docs, Google presentation, and Google spreadsheet.

The third link (to the Google in education link) is the one I found most helpful. It was right on the Google site and it has links and tutorials for all other Google apps
