INTRODUCTION

English translation pending.

CORE DEFINITION

OK4R is a study reading method built around multiple passes rather than a single linear read. Overview surveys the structure of the material through headings, summaries, and organization. Key ideas identifies the core concepts and arguments. The first R is close reading, working through the text in detail. The second R is recall, reproducing the main points from memory without looking. The third R is reflection, connecting the material to existing knowledge. The fourth R is review, revisiting the material at intervals. The method assumes passive reading produces weak retention and that retrieval plus spacing move material into long-term memory.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Use structural overview: survey headings, summaries, and organization before reading any detail. - Use closed-book recall: reproduce the main points from memory rather than rereading the passage. - Use spaced review: schedule return visits instead of finishing the chapter once.

Anchor fast decisions

A single pass through unfamiliar text produces recognition without retrieval practice, and recognition fades quickly. Separating the overview from the close read gives the reader a structure to attach details to, which improves encoding. The recall step forces retrieval, which strengthens the memory trace far more than rereading, and it also exposes gaps that reading over them would conceal. Reflection links the new material to existing knowledge, and spaced review counters forgetting by returning to the material after the trace has begun to decay.
