Students create word processing, spreadsheet or presentation artifacts in GoogleDocs. All GoogleDocs files can be shared for collaboration with other students in collaborative projects, or with teachers for feedback.

Documents are the standard word processing files, where students can create online, or upload from an existing Microsoft Word or Open Office word processing file. 

Spreadsheets are the standard spreadsheet applications which can be imported from an exisrting Microsoft Excel or Open Office spreadsheet file.

Presentations are the standard slide show application which can be imported from an existing Microsoft Powerpoint or Open Office presentation file. Other people can be sent the URL for the presentation, and they can view the presentation in real time. 

Here is a short YouTube video about GoogleDocs that discusses the process. Here is a brief description of how to use Google Docs Spreadsheet to facilitate feedback from small group breakout discussions.

Students store their video clips online to link into their Docs or Pages.
