The document discusses diversity in the classroom and how Universal Design for Learning (UDL) can help address this issue. UDL aims to make instruction accessible to all students by allowing multiple ways for students to engage with and demonstrate their learning. It provides flexibility in how curriculum content is presented, expressed, and engaged with. UDL is based on neuroscience and how the brain learns through multiple pathways. When applied through technology, UDL can introduce flexibility and differentiated instruction to meet individual learner needs and engage every student.
