Comprehensive Content Analysis Dataset of the Iranian High School "History 2: From the Mission of the Prophet of Islam to the End of the Safavid Era" Textbook: A Multi-Agent Adjudicated Protocol (CAP) Based on the William Romey Method

This dataset provides a rigorous, multi-modal, and peer-adjudicated content analysis of Chapters 1 to 7 of the Iranian National High School textbook, "History 2: From the Mission of the Prophet of Islam to the End of the Safavid Era" (Grade 11, Humanities), using the William Romey Method. Developed as an empirical open-data initiative at Farhangian University (Nasiabeh Campus, Tehran), this project aims to enhance teacher agency by transforming pre-service teachers into Intelligent Supervisors of national curricula. The repository is structured chronologically across two specialized student-teacher research cohorts: Chapters 1-4 were systematically evaluated by Fatemeh Bazgir, Negin Heydari Aliabadi, and Masoumeh Shirali; Chapters 5-7 were audited by Seyedeh Fatemeh Zarei, Seyedeh Zeynab Sadati, and Faezeh Jamal Livani. The analytical matrix encompasses a comprehensive evaluation of four core curricular dimensions: textual narratives, visual illustrations (historical art, maps, and artifacts), integrated classroom activities, and sample evaluation questions. To ensure structural validity and eliminate individual or AI-generated systemic biases, the dataset was generated via the 4-stage Collaborative Adjudication Protocol (CAP): (1) Methodological training based on open-access lesson plans (DOI: 10.5281/zenodo.20568759); (2) Baseline AI-assisted auditing; (3) Peer human-AI cross-auditing utilizing four distinct operational roles (First Auditor, Second Auditor, Prompt Engineer, and Documentation Manager); and (4) Final CAP reconciliation and multi-agent text adjudication. This dataset serves as Volume 2 of the Iranian School Textbook Auditing Repository.
