Adaptation of Digital Teaching Content

4. Applying Accessibility Principles (WCAG)

Digital content should be accessible to everyone, including students with disabilities. Follow the basic principles of the WCAG guidelines (CAST, 2024; W3C, 2024):

• use high-contrast colours for text and background;

• add captions or transcripts for video and audio content;

• write in clear and simple language (W3C, 2024);

• enable keyboard navigation;

• use alt text for images (W3C, 2018; Ally, 2019).

Tip: 

Test your materials using accessibility checking tools (e.g., WAVE, axe Accessibility) (W3C, 2018).
