THE PERSISTENCE OF STUDENTS’ UNFOUNDED BELIEFS ABOUT ELECTRICAL CIRCUITS: THE CASE OF KIRCHHOFF’S LAWS
Bibliographic record
Abstract
Conceptions of college students (ages 17-20) concerning Kirchhoff's laws are derived from a written questionnaire and individual interviews. The qualitative methods of investigation are similar to those of Piaget. The 169 participants, all from the Province of Quebec in Canada, were enrolled in an electronics technicians program. The difficulties experienced by these students indicate a drastic discrepancy between their conceptions and the scientific view. An extremely inadequate understanding of the concepts of voltage and current appears clearly in the background. The conclusion is reached that higher priority should be given to Kirchhoff's laws, which remain the two fondamental laws of circuit theory.

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.
