This document discusses Universal Design for Learning (UDL) with a focus on cognition and learning. It introduces the "myth of average" and explains that students differ widely in their cognitive processing skills. It then outlines four areas of cognition: input, integration, memory, and output. For each area, it provides examples of cognitive processes and instructional scaffolds to support students. It emphasizes integrating different scaffolds and adjusting levels of complexity based on individual student needs. The overall goal is to understand how cognition impacts learning and to apply UDL principles to support diverse learners.
