"The UDL Curriculum Toolkit is an open-source web application designed to support the creation of interactive, multimedia curricula according to the principles of Universal Design for Learning (UDL). Technically, the UDL Toolkit is a configurable application with resources to create UDL content on the web — a collection of Java packages and resources such as style sheets, graphic design assets, and documentation. The feature set includes a system of supports and scaffolds based explicitly on the UDL Guidelines (CAST, 2011) that can be customized to any curricular context."
"In essence, the UDL Toolkit provides a frame for curriculum development with features that facilitate comprehension (e.g., highlighting, accessible text, vocabulary support), that encourage action and expression (e.g., notetaking, prompts for writing, drawing, and audio recording), and that recruit and sustain engagement (e.g., video, teacher feedback, collaborative whiteboard). Teachers can use the application to track students' progress; see and compare their responses, highlighting, and notes; and provide individual or group feedback. For research purposes, the application includes detailed logging of students’ actions, and the ability to turn on or off program features."
