Hypothesis is a “social annotation” tool, focused on deeper engagement with course materials, critical reading, and dialogue between students and instructors. Instructors provide reading or video materials to students, who can then annotate and add comments to discuss with one another. Hypothesis is best used to create a discussion centered around a reading or other course resource.
