This chapter describes the design and development of a self-paced, online instructional unit that was designed to provide just-in-time support for students enrolled in legal-studies-related courses (interpreted to include justice studies, criminal justice, and business law coursework). The instructional unit provides an orientation to legal terminology, legal research, and legal writing. The instructional unit also serves as an optional, web-accessible, self-paced orientation. Universal design for learning principles guided the design of the instructional unit as well as all supporting materials and exercises. The chapter presents an overview of how universal design for learning informed and influenced the design and development of the instructional unit. Findings from an associated mixed-methods research study are also shared.
