Abstract

fetched live from OpenAlex

In programming courses, test-based automated feedback systems often face a limitation: instructors cannot effectively enhance feedback during ongoing assignments. While a passing test case may adequately indicate that certain rubric criteria have been met by a student's program, failure can arise from many reasons. When a test case fails due to reasons not previously coded for, it can create confusion. This tends to divert a student's focus from genuine learning towards guessing the test. A more effective approach would be for the system to notify instructors when a test fails, rather than automatically returning a "test case failed'' message. Instructors could then diagnose the cause to provide an initial ''human-in-the-loop'' feedback. Subsequently, this feedback can be coded into the test suite. This method enables the improvement of feedback during an on-going assignment. In this poster, we propose an approach to achieve this objective and introduce a supporting tool.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
