q2 i? A subset of responses articulating issues with caption formatting or excessive slide data suggest the coherence principle is important to prevent wasting cognitive effort on distracting design choices. → Gehret 2025

Evidence¶

Gehret 2025¶

Gehret, A. U., & Elliot, L. B. (2025). Perceptions of e-learning by deaf and hard of hearing students using asynchronous multimedia tutorials. Education Tech Research Dev. https://doi.org/10.1007/s11423-025-10476-z

q2 · i? · qualitative · r2

A subset of responses articulating issues with caption formatting or excessive slide data suggest the coherence principle is important because DHH students are wasting cognitive effort focusing on or getting distracted by these design choices.

"In both cases, the comments are suggesting that coherence might be an important principle to consider because DHH students are wasting cognitive effort either focusing on, or getting distracted by, these design choices."
