📚 Research Digests & Reference

Evidence gradings, annotated bibliographies, glossary, and benchmarks — the shelf the other pillars stand on.

• Bibliography: the digital-skills evidence base
  The annotated source list for the teaching-digital-skills pillar — typing and HCI, search and evaluation, programming education, writing technology — each with why it matters and where the library uses it.
• Bibliography: the learning science this library stands on
  The annotated source list for the science-of-learning pillar — the meta-analyses, classic experiments and honest correctives we cite, each with one line on why it matters and where we use it.
• Bibliography: the online-safety and wellbeing evidence base
  The annotated source list for the safety pillar — the screen-time correctives, the bullying and bystander trials, the safeguarding literature, gaming and monetization research — with where the library uses each.
• Effect sizes for teachers: what d actually means
  The five-minute working knowledge — what an effect size is, why 'small' effects can matter enormously, why the famous 0.4 hinge is wrong, and the realistic benchmarks (Kraft) for judging classroom claims.
• How we grade evidence (and why every article carries a grade)
  The STRONG / PROMISING / MIXED / THIN scale used across the Learn library — what each grade requires, why we grade against our own interests, and how the replication crisis shaped the rules.
• Glossary: the terms this library uses
  Working definitions for the learning-science, digital-skills, and privacy terms used across the Wiz Kids Learn Library — each with a pointer to the page that treats it properly.
• Reading education research critically: a teacher's field guide
  The seven questions that sort strong claims from marketing — study design, samples, outcome measures, effect sizes, conflicts of interest, replication, and the grey-literature trap — with worked examples from this library's own sources.
• Typing speed norms: what the data actually supports
  The honest reference on WPM expectations — what large-scale studies established for adults, how thin the children's norm data really is, the practitioner heuristics and their status, and how to use any of it responsibly.
