The program includes
- collaboration on documents
- the ability to create google sites
- interactive calendar
- voice chat & video
- google groups which allow teachers and students to communicate easily
from the website I also found that the program is free, has good security and does not have any advertising.
I know that it was important to check out the actual website, and see if I could find some opinions on the program. From the google site I found some success stories.
I am continuing to try to find some opinions, and I hope I find more information!
