Video-Based Learning

The use of pre-recorded or streaming video as a primary medium for teaching skills, procedures, or concepts, ranging from YouTube how-to tutorials and MOOCs to specialised instructional content like safety training and vocational education. Video-based learning offers self-paced viewing, replay, and dual-channel (visual + auditory) presentation that can reduce cognitive load for some learners, but creates accessibility barriers for others when pacing is too fast, information density is high, or critical content is delivered through only one modality. For users with cognitive differences, the lack of explicit scaffolding, interactive clarification, and progress feedback often turns video's theoretical flexibility into practical inaccessibility.
