This paper discusses an optics assessment designed to measure problem-solving decisions in the context of optical engineering. It is part of a larger, cross-disciplinary collaboration to identify important problem-solving decisions across science, engineering, and medicine and create assessments that measure these decisions within the context of a given field. We describe the structure of the assessment, the problem-solving decisions it assesses, and our qualitative analysis for the refinement and preliminary evaluation of the assessment. We used think-aloud interviews to observe students’ problem-solving processes as they worked on this assessment. Students struggled with creating predictive frameworks, constraining the solution space, and reflecting on solutions. From the results of this analysis, we are creating a shorter, computer-based version of the assessment that still captures the most difficult problem-solving decisions, but allows for easier analysis and testing on a larger sample size.
