Following the fantastic reaction to our interactive learning experiments, we’ve decided to create an open source skill for anyone to build their own 💪🏗️ It's called the Marble-Builder. You tell it your child’s age and what they’re curious about and it builds a playable experiment for them. What’s built into the skill: - 1,837 concepts kids learn through primary school, and the 3,853 links between them - 1,049 teaching research records on how kids learn best - It agrees a plan with you, then builds, tests and fixes the experiment itself You stay in control and can adjust everything. AI is a tool with huge potential to make teaching even better for both parents and teachers. We want anyone with something to teach to be able to bring it to life in an interactive, personalized way. It’s a first prototype so there is a lot to improve. One big next step is to make the experiments more beautiful visually. Parents, teachers, homeschoolers: show us what you make. We’ll gather the best experiences into the first open, interactive encyclopedia for kids. Incredibly exciting times for kids education. Links to try it below 👇

In July we open-sourced a dynamic graph of everything a child learns in primary school. 1,590 concepts, 3,221 dependencies. Now we’re turning every concept into interactive experiments kids can play and learn from. First one, age 7: heat and water. Everything that used to be a boring textbook can now be an engaging experience, potentially tailored to every child. Kids education just got a massive upgrade.

Introducing the @withmarbleapp index: a simple a robust way to score kids entertainment. As a parent you can find age ratings but nobody tells you whether a title actually helps a child grow. So we built a way to measure it. You paste a link, we analyse, you get a score. Core principles are: -> 5 criteria: Curiosity & Creativity, Learning & Development, Respect for Attention, Online Safety, Physical & Sexual Safety -> Grounded in the research: Hirsh-Pasek et al.'s four pillars of learning, the LEGO Foundation on learning through play, Radesky et al. on manipulative design in kids' apps, the UK Children's Code, UNICEF's guidance on AI, the @korabench on AI safety for children, and Common Sense Media's rating criteria -> Every title comes with a parent guide: who it's for, watch together or alone, what to talk about afterwards -> The grid is versioned and has a test suite: a reference set of 200 titles (and growing) with expected score ranges per criterion -> Every score gets a confidence measure, by scoring each title several times and showing how much the runs agree -> Scores are continuously calibrated against child-development experts and existing ratings -> Every disagreement a parent sends becomes a candidate test case, so the reference set grows with use and each new version of the grid has to pass more cases than the last Let me know what you think.

Are they talking about me? 👀

48h. @withmarbleapp 👀

We just launched a generative craft system inside @withmarbleapp. Kids can now create anything and turn it into a 3D object on their map. It's designed to be realistic, so kids have to use their brain to make things happen. It works like this: 1) You describe or sketch what you want to build 2) Marble creates a blueprint you can iterate on 3) You pick the resources and tools you think you need to make it (if you have them) 4) Marble crafts the object. If the build is successful and you can drop it on your map! Since you can create your own tools, there is no limit to what you can build with this system. So excited to see what kids make with it!
