Episode notes
Knowledge In Head Vs Knowledge In World
- Knowledge can live either in the head or in the world, and design choices decide which works best.
- Instructional designers focus on knowledge-in-the-head while UX designers place knowledge in the world to support action.
Match Format To Learner Needs
- Match your format to learner needs: quick how-to for problem solvers, deeper practice for complex skills.
- Let experienced learners skip and self-select; provide indexed short resources for them.
Start By Diagnosing The Real Gap
- Identify the gap first: knowledge, procedure, skill, motivation, habit, or environment.
- Each gap implies different solutions like reference aids, practice, prompts, or environment redesign.
