Comparative Analysis of Instructions of Representative Values in Mathematics Textbooks from South Korea and Ontario, Canada
Bibliographic record
Abstract
Representative values, which represent the central tendency of the data, are the most commonly encountered by students in statistical data. It is important to understand what representative values to use and how to interpret the representative values according to the characteristics and context of the data. This study attempted to compare and analyze how representative values were structured in the curriculum and how they were dealt with in textbooks, focusing on Korea and Ontario, Canada and to find educational implications for teaching future representative value. The research results are as follows. First, there is a big difference in relation to the timing of teaching the representative values, and the representative values can be introduced from the lower grades of elementary school. Second, it is more appropriate to introduce the mode first in guiding the representative values. Third, it is required to organize a curriculum and textbooks that considers the connection between other learning contents and representative values in the area of data and possibility.

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.
