Law professor Diana Donahoe turned to CNDLS to help her design and create an online legal writing textbook. She envisioned an immersive environment that would simulate the activities of a junior partner in a law firm. By interacting with legal texts through the application (dissecting their parts, restating their arguments, and reviewing their structures), students would develop their legal writing skills.

Ultimately, the CNDLS web development team and Donahoe produced an online textbook that covers all the materials a legal writing class utilizes. The interactive resources not only provide students with tools to improve their legal writing—including case studies, exercises, and streaming video testimonials from fellow law students and lawyers on effective research strategies—but also present faculty with new ways to teach it. The online textbook, known as "TeachingLaw," allows faculty to manage their entire through the interface. Instructors may upload new content, tailored for their specific class. Additionally, faculty can create their own interactive content on the site, employing all the interactive features of the existing assignments.

The program also allows students to: upload their assignments and receive commented responses; automatically report of the results of their self-assessment exercises in individual and cumulative scores; take online quizzes to clarify their understanding of particular grammar rules.

"TeachingLaw" was piloted in Diana's writing law classes and has since been sold to textbook publisher Aspen Law.
