INTRODUCTION

English translation pending.

CORE DEFINITION

Spaced practice, tied to the spacing effect, distributes learning over several separated sessions instead of concentrating it in one massed block. The mechanism is that each session's retrieval becomes slightly harder, which is a desirable difficulty that deepens encoding, and reviewing near the point of forgetting strengthens the trace, so the same total study time yields retention that lasts far longer.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Space it out: split content into short sessions separated by gaps rather than one block. - Review at the edge: schedule each revisit just before the material fades. - Keep it short: prefer many brief high-frequency sessions over one long cram.

anchor

Anchor fast decisions

Memory decays on a curve, and a retrieval that occurs while the trace is weak strengthens it more than an easy retrieval does. Spacing forces these difficult retrievals, and that difficulty is what deepens encoding, whereas massed practice produces fluent familiarity that fades quickly.
