SPRUCE for Researchers

We are currently developing a new research-based assessment instrument called the Survey of Physics Reasoning on Uncertainty Concepts in Experiments (SPRUCE). We are doing this in partnership with Prof. Rachel Henderson and Prof. Marcos D. Caballero at Michigan State University (see here). SPRUCE will measure student learning connected to measurement uncertainty at the intro undergraduate level in the context of experimental physics.   

Our process for developing SPRUCE is based on Evidence-Centered Design (ECD). We started by interviewing intro physics lab instructors at a range of institutions across the United States, asking them about the concepts, practices, and activities connected to measurement uncertainty. This Domain Analysis process serves as the foundation for Domain Modeling, which in turn supports the Conceptual Assessment Framework and the Assessment Implementation and Delivery.
