| Abstract Title: | Converting an open-ended assessment for upper-division quantum physics to multiple-choice format |
|---|---|
| Abstract: | As part of an ongoing investigation of students' learning in upper-division quantum mechanics, we need a high-quality conceptually focused assessment instrument. Such instruments can also be useful for comparing outcomes of different curricular approaches. We started by building upon an existing 14 item open-ended Quantum Mechanics Assessment Test (QMAT). However, open-ended tests require complex scoring rubrics, are difficult to score consistently, and demand substantial investment of faculty time to grade. By converting QMAT to multiple-choice format, we have begun the process of constructing a 30 item concept inventory for upper division quantum topics. Here, we present elements of the development process, including analysis from a preliminary study conducted at Cal Poly Pomona and CU-Boulder. We are investigating test reliability using classical test theory, as well as using student interviews to further establish validity of the multiple-choice format. |
