Exploring Additional Personalized Support While Attempting Exercise Problems in Online Learning Platforms
Bibliographic record
Abstract
In online asynchronous learning environments, students are assigned exercises, but it is not clear how to incorporate the kinds of actions an in-person tutor might take such as explaining, providing more practice, prompting for reflection, and motivating. We explore approaches to adding "Drop-Downs'' that appear after a student submits an answer and that contain additional information to support learning. We conducted randomized A/B experiments exploring the impact of these Drop-Downs on student learning in the online portion of a flipped CS1 course. The deployed Drop-Downs in this course provided explanations, reflective prompts, additional problems, and motivational messages. The results suggest that students benefit from various Drop-Downs in different contexts, indicating the possibility of personalizing content based on the student's state. We discuss the resulting design implications of Drop-Downs in online learning systems.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
