The document discusses diversity in the classroom and potential solutions using Universal Design for Learning (UDL). UDL aims to make instruction more accessible and flexible for all students by presenting curriculum in multiple ways and allowing multiple means for students to demonstrate learning. It does this through three principles: providing flexible ways to present content, different expressions of learning, and multiple options to engage students. UDL uses technology and assessments of student differences to customize instruction according to individual learner needs and strengths in order to engage every student.
