Overview

Logo with tagline: Perusall - Every student prepared for every class

Perusall is a free “social annotation” tool that helps students engage with course material in class groups. When integrated with HuskyCT, instructors can create reading or viewing assignments in which students create & share their own annotations and respond to each other’s comments and questions. Perusall informs instructors of the concepts that generate the most student questions & discussion, and Perusall can assist instructors score assignments quickly and efficiently. Perusall also reminds students of incomplete assignments, prompting higher rates of completion and preparedness.

Why Use Perusall?

If instructors are concerned that their students are not getting the most out of their reading assignments, Perusall can help. Below is a snapshot of the impact of Perusall on student reading engagement:

  • 90–95% of students completed all but a few of the reading assignments before class” (*Miller et al., 2018)
    • Compared to 20-40% otherwise; most of the literature reports that 60–80% of students do not read the textbook before coming to class (Cummings et al., 2002; Clump et al., 2004; Podolefsky and Finkelstein, 2006; Stelzer et al., 2009).
  • 80% of students complete 100% of the reading assignment before class” (*Miller et al., 2018)
    • Compared to the average: 28% of the assigned reading completed before class. (Clump et al., 2004)
  • Students read for a longer period of time (measured by Perusall) than what the research indicates as the average student reading time (student-reported) (*Miller et al., 2018)
  • “Students using Perusall perform significantly better on in-class exams” compared to students using a different annotation tool (*Miller et al., 2018)
  • “Perusall contributes to deep learning and … students who perform the annotation assignments as required obtain significantly higher examination marks” than their “average mark” in other courses. (Suhre et al., 2019)
