Changing Scientific Reasoning Ability in College Students Brian A. Pyper Ph.D. Director of Physics Education BYU-Idaho Department of Physics
Abstract Data from several years and several different classes have shown that Lawson test scores do not change much over the course of a single semester, and are strongly correlated with FCI gains. So what does change Lawson scores? We have new data that we think shows that more interaction with materials that demand reasoning (and not just clicker questions and end of chapter Homework problems) improves reasoning ability and subsequently conceptual development.
Reasoning and Conceptual Understanding Reasoning and Understanding strongly correlated
Changing Reasoning Measured by the Lawson Classroom Test of Scientific Reasoning F08 PHS100 No significant changes: using peer instruction and some home-made tutorial-like activities.
+ tutorials Adding one day a week with Tutorials in Introductory Physics (Ph105)
Concept development FCI: F08, W10, F10 HTCE: W11
Notes • Tutorials are research based and dependent on faithful implementation • Workbooks take MUCH longer to complete (time on task) • Students have similar mixed feelings about both
Conclusions • Reasoning Ability matters and can be encouraged by appropriate interventions • But it doesn’t change just because of life experience or even previous math/physics background. It takes explicit attention to reasoning.
