-Description & Dimension: Many online learning platforms rely heavily on videos without accurate closed captions or audio descriptions, and interactive diagrams that are incompatible with screen readers. This impacts the disability dimension (specifically visually and hearing-impaired students).
-Why it is Exclusionary: It creates an uneven learning environment where students with disabilities are unable to access core educational content independently or accurately.
-Teacher's Response: A practical step is to audit all digital resources before assigning them, ensuring closed captioning is enabled, text-to-speech compatibility is verified, and alternative text-based summaries are provided for visual content
