Digital content and online learning platforms are regularly found to be inaccessible.
“Furthermore, even if digital learning materials are often better than printed ones handed in classrooms (Fichten et al., 2020), digital content and online learning platforms are regularly found to be inaccessible (Alcaraz Martínez et al., 2021;García-González et al., 2021).”
From Exploring the role of generative AI in higher education: Semi-structured interviews with students with disabilities (2025) · cites this paper as Alcaraz Martínez et al., 2021
The Introduction (page unavailable) says accessible statistical charts for visually impaired users remain scarce, and the Validation stage reports multiple accessibility problems in the charts evaluated. This supports the point for a specific type of digital content, but the paper does not establish that digital content generally or online learning platforms are regularly inaccessible.

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.
