Universal Design for Learning (UDL) is a framework to drive inclusion in learning. It takes three factors into consideration to promote access and ability to learn by anyone despite barriers, challenges, and circumstances. They are; (1) Engagement - stimulating the interest and motivation by considering the audience, (2) Representation - multi modal presentation of material, and (3) Expression - enable learners to express what they learned in different ways.
Use these guidelines in your next learning program design and development.
