Hi everyone, as it is stated in the article of Carroll (2000), instead of being a solo teacher and teaching in isolation from the rest of the other colleagues and the other students, collaboration and information sharing can create tremendous effect on education.
In our country, as far as I observe, EBA does so significant works in terms of collaboration issue of teachers. In the following link, there is a free, content development tool called XERTE. This gives output with HTML5. It means the product can be embeded in tablets or smart phones easily. You can examine the demo at http://xerte.eba.gov.tr/ address.
Enjoy it =)
