In May 2010 I set out to create this poster size guide for teachers, allowing them to compare the functionality and pedagogical advantages of some standard Moodle tools, adding a column to indicate how tricky the tool is to set up.
After I posted it on my blog with a Creative Commons license, it spread across the Moodle Community. Many education technologists and organisations have since adapted the guide for their own purpose.
For all of the versions and translations, please refer to my blog page http://www.cats-pyjamas.net/moodletoolguide
I decided to repost it here on Slideshare, to make it more findable.
