Classroom outdoor tracker
The Taiwan insight, sized for a corkboard: what gets tracked gets protected. A class marks its outdoor minutes daily for four weeks, then looks at the chart together.

Write outdoor minutes in each box (recess + outdoor lessons + walks). Cloudy days count — outdoor light beats indoor light even under grey sky. Four-week class record: minutes.
Why we track: outdoor daylight is the one nearsightedness prevention shown to work in randomized school trials (He 2015, JAMA; Wu 2013, Ophthalmology). Details for parents & teachers: lesspix.com/school/
Running it
- Let students keep the chart. A rotating "light keeper" who fills in the day's minutes turns policy into a game.
- Don't chase perfection. The chart's job is visibility; even a low-number month starts the right conversation at the next staff meeting.
- Close the loop: after four weeks, send the totals to the PTO with the one-page handout.
The home version of this habit is the outdoor line in the family screen agreement.
