MinimalDataset_Instruments_Pygmalion_UTN

This repository contains the minimal dataset and reproducibility materials required to verify the principal findings reported in the article:“Perceptions and Expectations in the Classroom from the Perspective of the Pygmalion Effect.”Two language versions of the documentation are included:MinimalDataset_Pygmalion_UTN_EN/ → English-translated documentationMinimalDataset_Pygmalion_UTN_ES/ → Original documentation in Spanish1. DATAAnonymized datasets in .xlsx format.Data are separated by participant group:StudentsTeachersIncludes Likert-scale responses used in the Confirmatory Factor Analysis (CFA).All datasets were cleaned and processed to remove personal, sensitive, or identifiable information.2. ANALYSISR scripts used to perform Confirmatory Factor Analysis (CFA) using the lavaan package..RData and .Rhistory files preserving the complete RStudio working environment.Intermediate outputs generated during the analytical process.Scripts are structured to allow full replication of reported results.3. FIGURESVisual structural models developed in Microsoft Visio.Figures are based directly on CFA results obtained in R.Models correspond to the factor structures reported in the article.4. INFORMED CONSENT AND ETHICSInformed consent forms used during data collection.Ethical approval documentation (if required by institutional review board).Full anonymization procedures were implemented.The study complies with institutional ethical standards and international research integrity guidelines.5. INSTRUMENTSThis folder includes the original questionnaires used in the study, together with validation and reliability documentation.Applied InstrumentsCCS – Classroom Climate ScaleITIS – Implicit Theories of Intelligence ScaleSPED – Student Perception of Educational DevelopmentSPPS – Student Perceived Psychological SafetyTEQ – Teacher Expectation QuestionnaireIncluded DocumentationStructured Likert-scale questionnairesDelphi-method validation checklistsTechnical reports on reliability and internal consistencyExpert judgment documentationFactor structure validation reportsAll instruments were administered to both students and teachers and were validated prior to implementation to ensure methodological rigor.6. REPRODUCIBILITY STATEMENTAll analyses can be replicated using the included R scripts and datasets.The provided materials allow verification of:Factor structure estimationReliability indicesStructural model estimationReported statistical outputs7.
