UDL is a framework that provides equal opportunities for all students to learn by removing barriers through flexible methods, materials and assessments. It involves presenting information through multiple formats like visual, auditory and kinesthetic. Teachers should provide varied tools and ways for students to interact with content and demonstrate knowledge, regardless of abilities. The goal is a supportive classroom environment that engages students through relevant, interest-based activities incorporating cultural and ability considerations. UDL aims to activate all parts of the brain for learning through recognition, strategic, affective and top-down/bottom-up processing.
