In this activity focused on evaluating sources, students respond to the question "What makes a source 'good'?" by collectively brainstorming a list of characteristics they should look for in evaluating a source, then using their list to evaluate different types of sources on the same topic (e.g., a scholarly article, an op-ed, and a news article). As a class, students discuss whether their source was "good" based on the class's list of characteristics and for which types of information needs or settings their source might be most appropriate.
