I do wonder if people think that wordpress is just a blogging tool and do not realise the power that it has over developing and maintaining content. I for one have used it for portal pages, so it is easy for people to put up content, inform about house points, develop specific pages on teaching and learning. Looking at the showcase on wordpress gives students a idea on what the power of this platform has available.
A number of years ago I attended a presentation on silverstripe and saw the development of the platform. One thing I think is people install it and see just a basic page, its not until you start working through the themes that you start seeing what can be done. I would love to find a resource on developing wordpress for high school students.
Doing some research tonight, I found http://www.wpyogi.com/ which looks to have some good tutorials on it, free to download. It is in a git hub format, which is awesome, simple to download and get working.
Now moving into server environment at school, ready to download and see whats available
I found this thread on developing wordpress in schools, some good ideas http://wordpress.org/support/topic/teaching-wordpress-in-highschool
There is this curriculum pack for wordpress http://highschoolwebdesign.com/introduction-to-wordpress-course/
An interesting discussion on presenting wordpress to students http://tommcfarlin.com/wordpress-in-high-school/
But then is it worth going down the wordpress line, I realise that there are other CMS systems and that they should be explored for there advantages and disadvantages.
