INTRODUCTION

English translation pending.

CORE DEFINITION

From the Analects: review the old to know the new. It means gaining new understanding by reexamining old knowledge and experience. Innovation rarely appears from nothing; it is mostly a new combination of old elements. Reviewing a past project is not for writing a report but for mining the insight that was missed the first time.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Mine the old project: review it for missed insight, not for a report. - Recombine old elements: treat innovation as new arrangements of existing pieces. - Teach to force new readings: explaining old material surfaces what you had not noticed.

anchor

Anchor fast decisions

Old material is already stored, so re-examining it costs little and supplies stable raw material for recombination. New contexts act as new lenses on that material, revealing relations that were invisible when it was first learned, so review becomes reconstruction rather than repetition.
