[Medical Education Development 2012; 2:e5] [page 17] The Virtual Anatomy Lab:an eDemonstrator pedagogicalagent can simulatestudent-faculty interaction andpromote student engagement
Bibliographic record
Abstract
As medical curricula evolve, many universi-ties have adopted a clinical case-centered med-ical curriculum with a strong focus on small group learning and reduction of traditional lec-tures such that anatomy has become a self-taught subject supported by e-learning mod-ules. One caveat of this approach is decreased student-faculty interaction and reduced stu-dent engagement. Thus use of e-learning must be balanced with the need for continued stu-dent-faculty interaction to promote healthy student engagement. To both support self-directed learning of anatomy and to simulate student-faculty interaction, we created the Virtual Anatomy Lab (VAL) that features a human pedagogical agent, called the eDemonstrator, who guides student navigation through the available learning resources. The VAL was evaluated using a mixed methods approach (usage statistics and focus groups) by two medical student populations at the University of Ottawa: first year medical stu-dents in a revised curriculum where anatomy lectures were abolished and laboratory ses-sions were self-taught, and second year med-ical students in the former curriculum in which anatomy lectures were given in advance of each laboratory session. We conclude that online modules such as the VAL, well designed with a human pedagogical agent, can be used within the curriculum without negatively impacting student engagement. Ethical Approval for this study was obtained from the

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
