the claim

Extra credit improves student learning outcomes.

the verdict
CONTESTED PARTIAL
Recorded sources
2 sources for · 1 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that extra credit improves student learning outcomes?

Partly. One auditing-course survey reports students perceived extra-credit group work incrementally improved their grades, and one physics study found scaled extra credit associated with higher exam scores. A separate study of an optional extra-credit adaptive learning tool found no gains in learning outcomes, so the evidence is mixed and partial.
