Can Recess Be More Important Than Class?

Danish researchers analyzed over two million test records and discovered that a twenty-minute break carries the cognitive weight of nineteen school days. For every hour the day advances, student scores drop by 0.9 percent of a standard deviation; a break before testing reverses this, adding 1.7 percent. Ariga and Lleras's experiment revealed the mechanism: attention isn't a depleting fuel tank but a goal that goes stale. Two seconds of task-switching prevented an hour's decline. The break isn't rest. It's a reset.

You'll learn:

- Why students in the lower performance tier lose most when breaks vanish

- The 20-minute threshold below which micro-breaks fail to boost performance

- How natural settings outperform concrete environments for sustained attention
