Informing Early Childhood Teacher Preparation for Sustainability-Oriented STEM Education: Evidence From a Renewable-Energy Program and Teacher Practice Survey

This record provides the full supplementary package for the article “Training Program Based on the Use of Renewable Energy Physics Concepts to Develop Higher-Order Thinking Skills in Kindergarten Children”. It includes de‑identified child‑level scores, teacher item‑level responses (Q1–Q40), computed teacher scales, the SPSS syntax to reproduce all analyses, final summary tables, and documentation **Contents (files):** - `children_for_spss.csv` – Child‑level HOTS (pre/post; n=60; 0–100; de‑identified). - `teachers_items_final.csv` – Teachers’ item‑level responses (Q1–Q40; N=102; 1–3 Likert). - `teachers_scales_for_spss.csv` – USE/HOTS means (1–3) with 0–100 rescaling + experience. - `updated_analysis_outputs.xlsx` – All descriptive/inferential outputs (paired t, g, OLS, CIs). - `build_SPSS_dataset_v2.sps` – End‑to‑end SPSS syntax (import → scoring → tests → regression → saves). - `VARIABLE_DICTIONARY.xlsx` – Variable names, definitions, scales, and coding. - `Results_Tables.docx` – Camera‑ready tables (pre–post, g, teacher scales, regression, flow). - `Data_Availability_Statement_HSSComms.txt` / `Code_Availability_Statement_HSSComms.txt`. - `Teacher_Questionnaire_EN.docx` – English version of the 40‑item questionnaire. -`Supplementary_Package_REP_444ae995_v2.zip` – ZIP including all items above. **Scoring & methods (brief):** Teacher items use a 3‑point Likert scale (1=does not apply; 2=applies somewhat; 3=strongly applies). Two subscales are computed as item means: **USE** (Q1–Q30) and **HOTS Support** (Q31–Q40) with optional 0–100 rescaling via (mean−1)/2×100. Child HOTS are scored 0–100 (pre/post). Analyses include paired‑samples t‑tests (ΔM, SDΔ, Cohen’s d (paired), 95% CIs), normalized gain **g = (post−pre)/(100−pre)** with 95% CIs, and an **OLS** model predicting post from pre and teacher‑level indicators plus experience. **Ethics/Privacy:** Child data are de‑identified; no direct identifiers are included.
