Episode notes
CTA Videos Boost Learning And Retention
- CTA-based training reliably outperforms non-CTA training on learning and performance outcomes.
- A double-blind randomized study with >1,000 biology students showed CTA videos improved lab report interpretation and reduced dropout, especially for women.
Fill Experts' Omitted Steps With Procedural Scripts
- CTA scripts shifted the instructor from storytelling and high-level concepts to explicit procedural how-to steps.
- Feldon converted expert decision rules into scripted procedural narratives that filled experts' omitted gaps and improved novices' ability to perform.
Procedures Beat Concepts For Novice Performance
- For novice training prioritize proceduralized decision trees over abstract concepts.
- Feldon: if trainees can follow the CTA procedure without understanding underlying concepts, training is high quality because converting principles to practice is cognitively costly in the moment.
