Anonymized Rubric Data and Reproducibility Materials for Technology-Enhanced X-Ray Diffraction Assessment in STEM Education

This dataset and reproducibility package supports a retrospective mixed-methods
study of technology-enhanced assessment in STEM education using X-ray
diffraction interpretation as the disciplinary context.

Supplementary Data S1 contains anonymized report-level rubric scores for 11
group laboratory reports, including scores assigned by the principal and
external evaluators, variable definitions, statistical summaries, datasets used
for figure generation, and validation checks.

Supplementary File S2 contains the complete R script, reproducibility
instructions, session information, validation results, machine-readable
statistical outputs, and reproducible versions of Figures 4–6. A copy of
Supplementary Data S1 is included within the reproducibility package to allow
standalone execution of the R workflow.

The deposited materials contain only anonymized group-level report identifiers
(E1–E11). They do not include student names, institutional identifiers,
individual grades, or original laboratory reports.

The materials are associated with a manuscript examining the distinction
between operational use of professional analytical software and critical
evaluation of software-generated outputs in STEM education.
