Bursting the belief in filter bubbles: A single-class activity to enhance critical thinking on algorithmic personalization

<i>This activity is suited for courses on online communication, political communication, media sociology, and concepts/theories in communication. It can be applied at different levels (bachelor, master, continuing education) and in classes of different sizes (from about 15 to several hundred students).</i> <i>After having completed this activity, students will be able to explain the concepts “information intermediaries,” “algorithmic personalization,” and “filter bubble”; synthesize the state of research on filter bubbles; and critically and realistically discuss societal risks and chances associated with these phenomena.</i>
