This workshop is designed to help participants choose and use a variety of tools and techniques for assessing student learning in STEM courses that can help us better understand our students’ performance in the classroom, and also contribute to assessment needed for specialized accreditation such as ABET or NAAB. We will discuss important concepts underpinning successful classroom assessment of student learning, describe a variety of tools and techniques for STEM courses, and note connections to helpful literature. During the session each participant will have an opportunity to select several potential new assessment tools or techniques for their own course, and plan for potential initial implementation for one or two of those tools and techniques.
