This sample is a very quick 3 slide presentation that I made up to demonstrate some of the features. It is very easy to work with and a straight forward platform. A couple of nice features is the availability to keep it on the Google Drive website for as long as you would like. Like much software these days, it runs on a "cloud" like storage -- where you are able to access this at all times, everywhere. It even looks good on a mobile device. The second feature that is nice is that you can embed this into a blog -- as shown above. You have the ability to share the document with only yourself or publiclly. I think that this type of document software would be useful in the classroom, not only for the teacher, but the student. Student's can now do work, forming and creating ideas and place them in a cognitive order that supplies a place for them to store their work to come back to. Educators can always set up these documents in order that they may monitor and grade their student's work. Again, it is another great tool to place in a child's hand so that they master the subject at hand!
