Instructors conducted a lesson study in which they designed, taught, observed, analyzed and refined a lesson on bystander intervention in a college introductory psychology class.
Learning Goals. The academic learning goal of the lesson was to develop students' ability to explain the "bystander effect" and how the presence of other people can affect individual behavior. A broader goal of the lesson was to develop students' ability to explain human behavior in terms of multiple factors or variables, which is an important facet of social science reasoning. This latter goal is important because students often resist the complexity of multiple factors and tend to rely on a single factor to explain behavior--something we call "The One Factor Theory."
Lesson Design. The lesson involved students in developing ideas about why bystanders help or do not help people in need. Prior to the lesson students did a homework assignment (pre-test) in which they read "bystander scenarios" that depict people in need of help. For each scenario they predicted whether the onlooker would help the person in need and then gave reasons why an onlooker would or would not help in the specific situation. In class students compared their answers on the pre-test and compiled a set of factors that influence people in bystander situations. The instructor then introduced a research-based model of bystander intervention, and led a discussion comparing students' ideas to the model. At the end of class each student wrote an individual analysis explaining the similarities and differences between the model and his or her group's ideas of bystander behavior. As a homework assignment, students analyzed another set of bystander scenarios (post-test exercise).
Major findings about student learning. On the pre-test students tended to explain helping behavior in terms of the bystander's character and personality (e.g., compassionate people help others). On post-test exercise personality-based explanations decreased and social psychological explanations (i.e., situational factors) increased. During the lesson students generated a wide range of factors involved in bystander intervention and developed plausible explanations for them. In general, they were able to think in terms of multiple factors on the bystander scenarios. Although the lesson evoked the kind of thinking we hoped for, we do not know whether this single lesson changed students' beliefs about the importance of situational variables as determinants of social behavior. For example, during the group discussion some students maintained that character and "upbringing" are primary determinants of bystander actions. The lesson may have uncovered a belief about human nature that influences students' willingness to accept social psychological explanations of behavior.
