Comprehensive Content Analysis Dataset of the Iranian Senior High School "History 3" Textbook (Grade 12 - Humanities Track) Based on the William Romey Method

This dataset provides a rigorous, multi-modal, and peer-adjudicated content analysis of Lessons 1 to 12 of the Iranian National High School textbook, "History 3" (Grade 12, Humanities Track), 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 four specialized student-teacher research cohorts: Lessons 1-3 were systematically evaluated by Zahra Khani Vanashi, Seyedeh Fatemeh Hosseini, and Nazanin Zahra Aslani; Lessons 4-6 were audited by Fatemeh Mohammadi and Masoumeh Navabi Moghaddam; Lessons 7-9 were audited by Melika Ghazi Nejad, Mahdieh Moharrami, and Negin Ezzati; Lessons 10-12 were audited by Zahra Ghahremani, Zeinab Taraj, and Atefeh Gharavi. The analytical matrix encompasses a comprehensive evaluation of core curricular dimensions: textual narratives, visual illustrations (historical archival images, portraits, and maps), 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 pre-registered lesson plans; (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 a dedicated volume of the Iranian School Textbook Auditing Repository.
