Retrieval practice
The testing effect — Roediger & Karpicke (2006). The act of recalling information from memory strengthens it more than re-studying.
Spaced repetition
The spacing effect — Ebbinghaus (1885), Cepeda et al. (2006). Distributing practice over time dramatically outperforms massed practice for long-term retention.
Interleaving
The interleaving effect — Kornell & Bjork (2008). Mixing problem types or topics within a session improves discrimination and transfer, even when it feels more difficult during practice.
Elaboration
Pressley et al. (1992). Prompting learners to ask «why» builds richer semantic networks with more retrieval paths.
Self-explanation
Chi et al. (1989, 1994). Narrating your own reasoning surfaces gaps in understanding and integrates steps into a coherent mental model.
Deliberate practice
Ericsson et al. (1993). Focused effort at the edge of ability, with feedback, is the mechanism of expertise development across domains.
Metacognitive reflection
Zimmerman (2000). Learners who plan, monitor, and reflect on their own process (self-regulated learning) consistently outperform those who don't — and develop transferable learning skills.
Motivation and identity
Nasir & Cooks (2009), Dawes & Larson (2011). Developing a sense of identity within a domain — and feeling a sense of purpose and capability — produces more durable motivation than external rewards or gamification.
