Inspired by Safiya Umoja Noble’s Algorithms of Oppression, essays and lesson plans in Critical Library Pedagogy (Nicole Pagowsky and Kelly McElroy, eds.), and the ACRL Framework for Information Literacy for Higher Education, this presentation described a critical pedagogy activity that interrogates systems of oppression in library research tools and challenges students to reflect on the emotional aspects of their research experience. We discussed how we have modified the activity for different courses and disciplines, classroom settings, and class session lengths. This activity is suitable for librarians who are beginning to consider how to incorporate critical pedagogy into their teaching.
