This CEM was created to be a tool for pre-service and in-service educators who want to learn about how the Universal Design for Learning framework can be used to make curriculum design and classroom instruction accessible for all students. There are two major sections in this CEM. The first section introduces Universal Design in architecture and product design, and illustrates how these ideas influenced the educational movement that has become Universal Design for Learning (UDL). Learner variability, which is the scientific foundation of UDL, is also introduced in the first section. The first section also includes an interactive journey through the principles and guidelines that make up the UDL framework. The final section provides the participants with an opportunity to integrate the framework into their lessons and classroom practice.
