Presentations are much more effective when one can see the face of the presenter and this software allows the presenter to do this digitally.  With present.me, simply upload your slideshow, click record, present into your webcam and then publish instantly to display in your Moodle course, blog or website.  Get 90 minutes of recording time with the free account.

If you assign group projects that utilize Microsoft Word, PowerPoint or Excel - consider the option of "collaborative software."  With collaborative software, all group members can access and edit their project at any time from any computer with an Internet connection.  

Collaborative Software through Gaggle

Students currently have access to Zoho software through their Gaggle accounts.  There is no set-up required and students can be given instructions on how to open a collaborative project in about 10 minutes of class time (see right).  I did this in two classes last week and students launched into using the software as it is quite straightforward and easy to use.  

Also, Gaggle provides great video tutorials and has an informative help section.  See the following:

280 Slides is a presentation tool available on the Internet – no software download is required. It is very similar to PowerPoint, but much more straightforward and easy to use (options include adding images, videos, text and shapes). All work is saved online so students can access their work anywhere with an internet connection. When students are ready to turn the assignment in, they can share the link with you or export it into PowerPoint and save it to your class dropbox.
