A teacher types in any topic they're teaching, and an interactive learning simulation gets built on the spot. That's the experiment Google Research is running. Title: The future of practice: Enabling teachers to create learning interactives with generative UI URL: Interactive simulations have always been expensive to build and limited in number, so here are three things that stood out to me. 🧩 On-demand creation via generative UI By combining LearnLM, a model family tuned for education, with generative UI (GenUI) technology, the system builds simulations on the fly for any topic, structured as levels with gradually increasing difficulty. It automatically generates the kind of scaffolding a teacher gives one-on-one: an intro to prime prior knowledge, a toolbox of formulas, tiered hints, and tailored feedback. 🤖 An agentic quality-assurance loop Generated simulations get self-corrected against three criteria: pedagogical (do the levels cover the learning goals), mechanical (do the buttons work, is it solvable), and visual (no unnecessary clutter). What's notably "agentic" here is that it actually opens a Chrome instance to click through and test the simulation. 📊 Strong ratings from real teachers In the UK, 40 STEM learning interactives were rated "good or excellent" overall. In the US, 12 teachers rated their custom-generated interactives an average of 8 out of 10. Over 30 STEM interactives spanning physics, chemistry, biology, and math are already live in the public library. It feels like a genuine attempt to scale the principle that "learning is not a spectator sport" using generative AI. #GenerativeAI# #EdTech#
