Looking for ways to evaluate or transform your physics lab course? We have developed multiple assessment tools including Colorado Learning Attitudes About Science Survey for Experimental Physics (E-CLASS), the Modeling Assessment for Physics Laboratory Experiments (MAPLE), and Survey of Physics Reasoning on Uncertainty Concepts in Experiments (SPRUCE) to help evaluate undergraduate physics lab courses. In addition, we have worked to transform multiple classroom experiences from a large, introductory level course to a junior level lab that focuses on modeling to a completely online course-based undergraduate research experience. In the topics listed below, we provide detailed information about the assessment tools, the course transformation processes, and linked course materials.
