This reference for designing a course aims for a more inclusive learning environment.

"Universal design for learning (UDL) is a teaching approach that works to accommodate the needs and abilities of all learners and eliminates unnecessary hurdles in the learning process. This means developing a flexible learning environment in which information is presented in multiple ways, students engage in learning in a variety of ways, and students are provided options when demonstrating their learning. 

UDL is similar to universal instructional design and universal design for instruction. All three advocate for accessible and inclusive instructional approaches that meet the needs and abilities of all learners. "
