LEARNER SELF-ASSESSMENT AND REFLECTION IN A PHYSICAL-GEOLOGY LABORATORY
To address reinforcement and feedback limitations, a new laboratory course includes significant in-lab time for student discussion and reflection. By reducing the material covered and setting aside 25% of the lab period at the end of class, groups may compare their work to determine why their answers are inconsistent, or collaborate to answer a question more complex than any single group could complete. Learners are more likely to ask for clarification in a discussion setting that encourages or requires questioning the instructor. The time also allows for self or paired assessment during lab, improving reinforcement and lessening the burden on graders. After completing an exercise, scholars are assigned a six-sentence, guided reflection that allows them to share a summary, their experiences, and any questions that remain unclear. Reflections are scored with a rubric to assess individual levels of engagement. Preliminary implementations during online instruction in Summer 2021 led to mild improvements to evaluation scores and markedly positive student comments compared to prior semesters. In-person labs utilizing the new approach are in progress, with weekly surveys that gauge learner interest.
