In this workshop, Oregon State Ecampus instructor Dr. Ciara Kidder shares ways that Perusall--a free, online social annotation tool integrated into Canvas--can be used to get students reading, thinking, and writing critically about course texts and materials. Dr. Kidder first introduces Perusall as a tool that allows students to provide direct commentary on text-based and multimedia course materials, including PDF documents, YouTube videos, podcast recordings, and more. She describes the different forms of low-stakes writing that Perusall can be used for, including sumarrization, critical question asking, and more. She then describes how Perusall's integrated grading system functions, as well as how faculty can customize it to the needs of their course or to reward multiple forms of textual engagement. She also shares examples of how she has integrated Perusall into lower-, mid-, and high-level courses to target different skill and knowledge levels at various stages of the degree program. To close, Dr. Kidder engages in a question and answer session with attendees.
