Reliable Rubric-Based Assessment of Physics Lab Reports: Data for Machine Learning

This dataset documents an assessment of de-identified lab reports written by students in a large-enrollment, inquiry-oriented introductory physics class. Students are asked to write four lab reports during the one-semester course. We conducted a post-hoc reliability study of the grades on two of the lab reports from several semesters. To achieve reliable assessments, we created assessment rubrics that are similar to but much more detailed than the rubrics that define the expectations to students. The dataset consists of plain text versions of the dicussion and concusion sections of the submitted reports, the grades assigned by TAs, and the assessment scores provided by the reliable raters.
