Is punk dead (in education)? What does EDUPUNK mean in 2026?

What Wikipedia says: “Edupunk is a do it yourself (DIY) attitude to teaching and learning practices [...] described [...] as ‘an approach to teaching that avoids mainstream tools [...], and instead aims to bring the rebellious attitude and DIY ethos of ’70s bands like The Clash to the classroom.’ [...] The term was first used on May 25, 2008, by Jim Groom in his blog, and covered less than a week later in the Chronicle of Higher Education. Stephen Downes [...] noted that ‘the concept of edupunk has totally caught wind, spreading through the blogosphere like wildfire’.” Next to this text, Wikipedia displays a photo of Jim Groom, captioned ‘Jim Groom as ‘poster boy’ for edupunk’.”
That was 18 years ago. Has Edupunk grown up? Maybe it's lost its rebellious nature? Is Edupunk no longer around? And what is his relationship to OER and open education? We can ask the person who invented it. Jim Groom will be in Hamburg and share his experiences, his insights and foresights.
