Abstract

Open-ended mathematical problems are a commonly used method for assessing students’ abilities by teachers. In previous automated assessments, natural language processing focusing on students’ textual answers has been the primary approach. However, mathematical questions often involve answers containing images, such as number lines, geometric shapes, and charts. Several existing computer-based learning systems allow students to upload their handwritten answers for grading. Yet, there are limited methods available for automated scoring of these image-based responses, with even fewer multi-modal approaches that can simultaneously handle both texts and images. In addition to scoring, another valuable scaffolding to procedurally and conceptually support students while lacking automation is comments. In this study, we developed a multi-task model to simultaneously output scores and comments using students’ multi-modal artifacts (texts and images) as inputs by extending BLIP, a multi-modal visual reasoning model. Benchmarked with three baselines, we fine-tuned and evaluated our approach on a dataset related to open-ended questions as well as students’ responses. We found that incorporating images with text inputs enhances feedback performance compared to using texts alone. Meanwhile, our model can effectively provide coherent and contextual feedback in mathematical settings.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
