Free, self-contained classroom activities — built to run entirely in a student's browser, in seven languages, with no logins and no data collected.
The Learning Activities Hub is a growing home for free classroom activities — reasoning breakouts, literature rooms, science investigations, lab-safety modules, and more. Everything runs entirely in a student's browser, in seven languages, with no logins, no accounts, and no data collected.
Miguel Guhlin conceived and directs the Learning Activities Hub — selecting the topics, setting the design and pedagogy, establishing the privacy-first and standards guardrails, and curating, editing, and reviewing every activity.
The content, code, artwork, and seven-language translations are produced with the help of generative-AI tools and refined under his direction and editorial review; a human stays in the loop on every decision. Each activity is built to be privacy-first and classroom-ready: it collects nothing, sends nothing, and works on any modern device.
Miguel Guhlin is a longtime educator and educational-technology writer focused on teaching, learning, and equitable access to technology.
