Zooming to Class? Experimental Evidence on College Students’ Online Learning during COVID-19
Open accessAbstract
One persistent question in higher education is the efficacy of online education. In the fall of 2020, we randomized 551 West Point students in a required introductory economics course across 12 instructors to either an online or in-person class as a response to the COVID-19 pandemic. Final grades for online students dropped by 0.215 standard deviations, a result apparent in both assignments and exams and largest for academically at-risk students. A postcourse survey finds that online students struggled to concentrate in class and felt less connected to their instructors and peers. Our results show detrimental effects for online learning.

The cited source says what the claim attributes to it.
In the citing paper
“Some of the best evidence on synchronous course use comes from a randomized controlled study at West Point during the pandemic, which found that students randomly assigned to synchronous online versions of courses had lower course grades than those assigned to face-to-face sections (Kofoed et al., 2024).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
