Measurement Uncertainty
Measurement uncertainty is a common learning goal in physics lab courses, especially at the introductory level. It acts as a fundamental aspect of many important laboratory skills, including designing and making measurements, analyzing and visualizing data, and experimental modeling.Ìý
To study learning about measurement uncertainty, we have used theÌýPhysics Measurement Questionnaire (PMQ),Ìýan established research-based assessment instrument. We are also developing a new such instrument for measuring learning about measurement uncertainty, the SurveyÌýofÌýPhysicsÌýReasoningÌýon Uncertainty Concepts in Experiments (SPRUCE).
