This video is about accessibility design principles and assistive tools for creating and using digital materials for teaching and learning. Examples related to three situations are covered: 1) adjusting the presentation of content; 2) preparing and using alternative formats for perceiving content through different senses; and 3) navigating and interacting with the materials.

This video is one in the IDEALeaders Self-Learning Series on the Co-Creation of Virtual Learning Accessibility. It is one of the deliverables of the Project entitled “Promoting accessibility of virtual teaching and learning through a train-the-trainer approach” funded by the UGC Special Grant for Strategic Development of Virtual Teaching and Learning in 2021-2023.

English captions are available.
