This blog has been updating you in the last two years about the most recent participatory learning methodologies that you can use in a learning context. One question always remained a little bit in the background, and that’s the old simple technique of asking a powerful question. Something you need almost always in the application of every facilitation technique whether it’s a  panel expert discussion or a  world café. To answer on what is the art and the architecture of a powerful question we have collected a series of interesting short publications on the topic? Do you have any other interesting resources to add?
