Verified content

• [abstract] Two experiments with a lesson on the Doppler effect: a control group studied normally; others studied expecting to teach, and of those some actually taught (a short video-recorded lecture) and some only prepared.
• [abstract] Experiment 1, immediate comprehension test: both teaching and preparation groups beat the control group (teaching d = 0.82; preparation d = 0.59).
• [abstract] Experiment 2, test after a one-week delay: only the teaching group significantly beat the control group (teaching d = 0.79; preparation d = 0.24).
• [publisher preview of the introduction] The teaching was a recorded lecture "as if" for another student with no prior knowledge; no live interaction.

Limits

• [assessment] Lab study; short paper-based lesson; teaching to a camera, not to a live peer. The immediate and delayed results come from two separate experiments. Participant population not checked in the full text (closed); the earlier note's "college students" is removed as unverified.
