Adobe Acrobat
Something cool: when you copy text from pdf file (not made from pdf maker) to Word, you will have some hard returns. To copy text in a good flow, in Acrobat: Advance menu-->Accessibility-->Add tags to document. It will create tags in PDF file. When you copy and paste again, it works like magic... collaborate: you can reply to somebody else's comments and you can see the thread. We put everybody's file on an internal server. It would be interesting to have students make comments to peer's work in this way. You can also add a streaming video from external url or browse for a flash such as a calculator and make them flow... Word: Acrobat ribbon. Portfolio: put folders, files, and media together and organize them. Use the extended version of Acrobat. More info: http://tinyurl.com/A9inEDUportfolio
