Highlighting Prosocial Affordances of Science in Textbooks to Promote Science Interest

摘要

The prevalent stereotype that scientific fields do not afford opportunities to fulfill goals of helping others deters student interest and participation in science. We investigated whether introductory college science textbooks that highlight the prosocial utility value of science can be used to change beliefs about the affordances of scientific work. In study 1, undergraduate students who were randomly assigned to read a science textbook chapter with added prosocial utility value expressed greater beliefs that the science topic afforded prosocial goals and increased interest in the scientific topic, compared with two control conditions. Mediation analysis demonstrated that interest was enhanced through increased beliefs that the topic afforded prosocial opportunities. Multiple group comparison tests indicated that underrepresented minority students (i.e., African Americans, Latinos, and Native Americans) might benefit the most from efforts to strengthen prosocial affordance beliefs. In study 2, we conducted a brief landscape analysis of science textbooks and found that texts are missing opportunities to emphasize the prosocial utility value of science. We discuss recommendations for science educators, curriculum designers, and researchers who want to increase and broaden science participation.
