Suplementary file of Research "Design and Evaluation of Socratic AI-Based Adaptive Scaffolding to Foster Critical Thinking in Secondary Physics Education in Indonesia '

It contains expert ratings from two validators across 20 validation items, together with the corresponding item-level Aiken’s V classifications and an overall validity coefficient of 0.90. The file also provides anonymized individual pretest and posttest critical-thinking scores for 135 Grade XI students, comprising 69 students in the experimental group and 66 students in the control group.

These data support transparency, reproducibility, and independent verification of the system-validation and intervention-effectiveness analyses reported in the manuscript.
