Beyond Representations: How Teachers’ Epistemologies of Models Shapes Students’ Engagement with Scientific Modeling
Bibliographic record
Abstract
Modeling is an important part of science education, with an “epistemology of models” underpinning modeling practices. While teacher professional development may emphasize the representational aspects of models, it may also overlook teachers’ epistemological understandings of models and its impact on teaching modeling as a practice. This study investigated how teachers’ epistemologies influence students’ development of models. We examined three science teachers’ epistemological perspectives on models, focusing on dimensions such as their understanding of the nature and purpose of the models, model multiplicity, evaluation, and changeability. Data from teachers’ interviews and classroom observations of teachers were analyzed using cross-case analysis. The results revealed that teachers’ epistemologies of models appeared to be manifested through two apparent paradigmatic lenses, primarily positivism and constructivism. Teachers operating with mainly constructivist perspectives encouraged students to build, evaluate, and revise models based on empirical evidence and scientific consensus. Conversely, those with mainly positivistic perspectives engaged students in model creation, primarily for verification or confirmation. Our findings indicate that two teachers sought evidence to support models, explored multiple models, and encouraged interpretive explanations, whereas one converged on existing “single-form” models. This study contributes to current understandings of the role of teachers’ epistemologies as part of their professional knowledge, highlighting its importance in shaping effective science education and model-based teaching.

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.
