Here is a Google Doc with a suggested format for running a Fail Club. Please read and add feedback. Then try it out with some colleagues and add feedback. Feedback from having tried this prototype will be massively helpful in evolving this idea!
Update: 24th August (in NZ)
I have recently created my own Fail Club with a small group of people working in education. We live in different cities so have decided to have monthly Google Hangouts to share our failures. The group was purposefully set up small amongst a group of 4, this allows us to trial how it works over GHO and allows for trust to build as well. We also all work for different organisations so that it mirrors the no hierarchy from the original post.
I came across this idea a few weeks ago at the Design for Social Innovation Symposium in Auckland, New Zealand. Fail Club is a group of 6 people (who coincidentally met doing an IDEO course) that meet monthly to share their recent failures. They all work for different organisations so there is no hierarchy, just a group of trusted people who they can share honestly with. See this blog post for more detail.
I can see huge potential for this in education. Having a group of trusted people outside my school to help deconstruct a failure would definitely encourage me to keep pushing forward. Haven't failed lately and meeting the group soon? Better try that that slightly scary idea, if it fails I will have something to share next week. Being people from different schools would also mean the shared lessons from the failures would spread to different schools so it could have a systemic change effect too.
