"I have found Hypothesis to be a great way to guide students through online reading, provide additional resources directly through the text, and engage them in online discussions of the text!"

"We love Hypothesis! This handy tool allows us to go deeper than any other platform because we can directly have discussions about a particular word/sentence/paragraph within a text. We even use it for peer reviews, and it works super well. It is such an easy tool to use, too!"

"I’ve found Hypothesis invaluable in engaging students with assigned reading material…The students say very smart things; they engage with each other very civilly and respectfully, and they synthesize their annotations with other class discussions, projects, and readings."

"I noticed that the personality of the students came through...I gain insight into the students beyond what is possible in the classroom. Even after we are back in person, I have enjoyed getting to know students via Hypothesis beyond a typical classroom response."

"Hypothesis is an excellent tool to engage students with the text and with each other. I used it almost weekly this semester."

Nancy Eberhardt, Ph.D.
"Hypothesis gets students talking to each other about the reading outside of the classroom in a way that I have never been able to see happen before. They come to class much more ready to talk about the reading, and I have a sneak preview of the issues they found most compelling, as well as the ones they might have missed"

"With Hypothesis, everyone’s visible to each other and so we really do have a chance at creating a learning community. Students get to know each other’s names. Conversations with Hypothesis feel very warm and collegial. Nobody has to be afraid of raising their hand"
