Just a quick note that we’ve updated our site/content Creative Commons license from
Attribution-NonCommercial-ShareAlike 3.0 Unported (CC BY-NC-SA 3.0)
to
Attribution-ShareAlike 4.0 International (CC BY-SA 4.0)
Aside from being newer and more generic, we’ve removed the NC (non-commercial) restriction as it’s essentially superfluous given the ShareAlike conditions, and simply a hindrance in many other respects.
For full information on the licenses, please do click through to the Creative Commons license pages for its awesome documentation and very detailed hints on how to best and properly use CC licensed materials.
For more information on the NC modifier, I recommend Erik Möller’s “reasons not to use a Creative Commons -NC license”.
The activities embedded in the programs make the subjects more engaging for the students as well as the teacher.
