The document discusses Universal Design for Learning (UDL) which aims to make education accessible to all students regardless of ability. UDL has three main principles: 1) provide multiple means of representation, 2) provide multiple means of action and expression, and 3) provide multiple means of engagement. The Center for Applied Special Technology works to expand learning opportunities for all through research and development of UDL resources and strategies. UDL guidelines include equitable use, flexibility in use, simple and intuitive use, perceptible information, tolerance for error, low physical effort, and appropriate sizing and space regardless of user abilities. The document advocates for teachers to follow UDL principles and for buildings and technology to accommodate all students to make learning more accessible and
