This PS: Political Science & Politics Teacher Symposium, "Wikipedia and Political Science: Addressing Systemic Biases in the Classroom" first appeared in the journal's April 2022 issue. Together theses essays discuss "systematic knowledge gaps in political science and politics on Wikipedia and the efforts by political scientists to ameliorate these gaps through student initiatives in higher education." (Michelitch & Ackerly). Below we have gathered the entire collection of essays, their supplemental work and associated teaching resources. We thank Cambridge University Press for making the articles available without charge through August 2022. You may view all of PS: Political Science & Politics special symposium collections here.
