The curricular context for the study is the commercially available Project-Based Inquiry Science (PBIS), a middle school science curriculum that focuses on standards-based content and uses project-based inquiry units to help students learn. In PBIS classrooms, students investigate as scientists would—through observations, designing and carrying out experiments, building and using models, reading about the science they are investigating, constructing explanations, and so forth—but in ways that are appropriate and meaningful for students and with carefully structured support.
