Set up the Cornell three-section page

Divide your page into three sections: a wide main column, a narrow cue column, and a summary section at the bottom.

Why it works

The physical structure of the Cornell page is not merely aesthetic — it encodes a workflow. The large main column is for capturing content during the session. The narrow cue column, filled in during review, forces compression and question formulation — activities that require deeper processing than re-reading. The summary section forces synthesis across the page. Each section corresponds to a distinct cognitive operation, converting page structure into a learning procedure.

How to do it

1. Draw a horizontal line 5–6 cm from the bottom of each page for the summary section.
2. Draw a vertical line about 6 cm from the left to create the cue column.
3. Leave the remaining right portion (roughly 65% of the page) as the main note column.
4. Use the cue column and summary sections only during review, not during the original session.

Evidence

The Cornell format’s three-section structure is a physical encoding of the "study cycle" (record, reduce, recite, reflect, review). The cognitive operations each section prompts — especially self-testing via the cue column — align with retrieval practice principles that are robustly supported in memory research. (mechanistic)

Direct studies on the Cornell format specifically show mixed results; the underlying practices it encodes (retrieval, elaboration) are independently well-supported.

Common mistake

Filling in the cue column during the lecture rather than during review — which converts a powerful retrieval-practice prompt into a simple outline duplication.
