Introducing secondary school students to big data and its social impact: a study within an innovative learning environment
Bibliographic record
Abstract
In this paper we report on a study of an innovative curriculum unit in which secondary school students learned about Big Data using real multivariate data with local and global contexts. The unit was designed to promote students’ covariational reasoning and engagement with big data concepts, while experiencing how statistical tools can be used to investigate trends and relationships to make decisions that can positively impact society. Inspired by notions of Classroom of the Future, the program used Interactive Orchestrated Learning Space (IOLS) and knowledge community approaches to create a multi-disciplinary learning environment. Students’ learning was investigated with mixed methods research tools. Findings from this study, including knowledge gains, are presented together with examples of students’ use of covariational reasoning to create arguments for change in a large city.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
