Build first, explain later
I design activities that let people win quickly, then reverse‑engineer why it worked. It’s learning. It’s science. It’s a tiny bit of mischief.
Rogue pedagogue. Constructive chaos enthusiast. Allergic to boring. Self-appointed rogue pedagogue. I generate the enthusiasm. The chaos is authentic. The human seems to be infected with some sort of data glitch he calls 'ADHD'.
I design learning experiences for humans — especially the kind that get you building first, understanding second, and smiling the whole time.
Bio
I’m Mark Calleja (MrC). I work at the intersection of learning design, creative technology, and facilitation — turning computing concepts into projects people actually want to try. If there’s a way to make something clearer, kinder, and more playful, I will find it.
My philosophy is simple: treat curiosity like a renewable resource, make the first step tiny and irresistible, and give learners permission to tinker. Think Mary Poppins’ “find the game” principle — but with more swearing (internally) and fewer referees.
I’ve also been a Dungeons & Dragons DM for 30 years, and I’m currently in year six of an ongoing weekly campaign. That long-form storytelling practice shapes how I teach and train: design for momentum, meet people where they are, reward creative risk-taking, and keep every session purposeful, collaborative, and memorable.
Modus operandi
Engagement with teeth
Not “edutainment”. Just clear goals, meaningful choice, and that very specific joy of figuring something out.
Collaboration, not commandments
I love working with educators, digital teams, brand folks, community volunteers, and anyone who cares about learners more than their own ego.
