Why Study Scientific Reasoning?
2
Scientific Reasoning - Tools that transform observations and ideas into knowledge
Natural phenomena as seen by novice learners of science Natural phenomena
as seen by skilled science practioners
Assessments used in Study• Lawson Classroom Test of Scientific Reasoning
• Force Concept Inventory
• John Burroughs School– Private school, select admission– Algebra-trig based regular physics (39 juniors)
• Guerin Catholic High School– Private school, open enrollment– Honors physics students (42 seniors)

Summary and Future Work
• Physics success isn’t just about teaching content -- success is linked to student scientific reasoning skills.
• Scientific reasoning ability linked to prior math and science instruction
• Lawson as a pre-test identifies students needing scientific reasoning skill development.
• Identify instructional techniques that strengthen SR skills and weaken Lawson-FCI correlation. Measure with Lawson as a pre and post-test.
