Data from Antarctica in the Chilean national curriculum

This dataset includes the data, scripts, and results of our study on Antarctica within the Chilean national curriculum, ensuring methodological transparency and full reproducibility of the analyses. It also includes documentation of coding quality and recoding checks, including a double-coded subsample of learning objectives, the R script used to quantify inter-coder agreement, and the corresponding reliability outputs. 1) Data (coding matrices) Table S1Full learning-objective-level coding matrix used in the study, including subject, grade, thematic categories, explicit mentions, coding scores, Polar Literacy links, and candidate legal-policy anchors. File S2Definitions of variables, coding scales, decision rules, Polar Literacy mappings, and legal-policy anchor criteria used in the coding process. File S3Inter-coder reliability results, including agreement metrics and brief explanatory notes for each variable type. File S4Summary tables underlying the main figures, including aggregated IOA values and Polar Literacy counts by subject and educational level. 2) Scripts (R) - run_all.RR script that reproduces the full workflow reported in the manuscript: data import, IOA computation (following the Methods definition), generation of all figures, and export of supplementary tables. - reliability_script.RR script used in reliability analyses. 3) Documentation - README.txtQuick-start guide describing the folder structure, required inputs, expected column names, and step-by-step instructions to run run_all.R.
