Hypothesis is a social annotation tool that allows students to read and comment on a text together. They can highlight and annotate readings online and to respond to one another’s annotations. 

This Hypothesis video provides a one-minute overview.

  • Students annotate together, reacting to each other’s ideas and collectively building knowledge and understanding.
  • Annotations offer instructors direct evidence of how students are reacting and engaging with the material.
  • Works with a range of content, such as articles, web pages, images, and YouTube video transcripts
  • Can be used across disciplines: annotate historical documents with context, analyze literary texts, define scientific terms in research articles, debate philosophical arguments, critique media transcripts, or connect environmental studies readings to real-world examples, etc.
  • For some students who are less likely to participate verbally in class discussions, annotating text can be more comfortable and give them a safer opportunity for engaging in text-based conversations.
  • With their own guiding annotations, instructors can demonstrate critical thinking, raise important questions or considerations when reading articles, or showcase strategies for critically analyzing particularly dense articles.
  • Hypothesis is integrated with Canvas, and student annotations and their replies are viewable in SpeedGrader. Also supports small groups and automated grading.
