Hypothesis is a collaborative, digital annotation tool, which  allows students to add comments, notes, and highlights to the margins of  a shared digital document, whether it is an article on the web or a  PDF. Annotation types include highlights, comments, notes, and replies  to other students' annotations and notes. Annotations can be made  public, private, or only visible to a group of students. The integration of Hypothesis into Canvas allows the tool to directly link to your Canvas files. Please keep in mind that Hypothesis will not work with materials in the Course Reserves area of your Canvas course.

Hypothesis features include:

• The ability for instructors to embed student discussions directly in digital texts.
• The ability for instructors to create assignments that allows  students to read and respond to their peers' annotations, prompting  reflection and promoting a sense of community.
• The ability to encourage joint student discussions and create active and social learning opportunities.
