Abstract
Postsecondary institutions are currently developing and applying innovative curricula to meet the future demand for land managers and planners with a solid knowledge of soil science. The objective of this study was to describe and evaluate the University of British Columbia (UBC) Farm problem-based learning (PBL) case study within the upper level, undergraduate/graduate Sustainable Soil Management course. The UBC Farm case led to compilation of a student-generated data set that dates back to 2004 and allowed students to work in collaboration with the UBC Farm managers and staff. Preliminary student feedback indicated that the UBC Farm case was effective at presenting the impacts of agricultural management practices on soil chemical properties and overall soil quality concepts. In addition, students found the hands-on activities of soil sampling, data interpretation, and working in collaboration with the farm staff to be stimulating. Having the opportunity to involve students in data collection each year allows instructors to build depth into the case, to ask more complex questions, and to cooperate with the farm manager in focusing on specific issues of relevance to the farm that change over time. This educational approach could serve as a framework for using PBL within postsecondary soil science curriculum in ways that support both student learning and natural resource management.

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 it
