Expert Validation Sheet of AI-Based Project-Based Learning (AI-PjBL) Model

The Expert Validation Sheet for the AI-Based Project-Based Learning (AI-PjBL) model is a structured instrument designed to assess the validity and feasibility of the developed learning model from expert judgment. The instrument encompasses five main aspects: conceptual feasibility, pedagogical validity, technological validity, practical feasibility, and overall assessment, each evaluated using a 5-point Likert scale ranging from “not appropriate” to “very appropriate.” It systematically examines the alignment of the model with constructivist and PjBL theories, the clarity of AI integration across learning phases, the suitability of the model for teachers in resource-constrained contexts, and the consistency between objectives, syntax, and expected learning outcomes. Additionally, it evaluates pedagogical coherence, technological adaptability under limited infrastructure conditions, and practical implementation considerations. The validation results, analyzed using Aiken’s V, indicate that most aspects achieved high validity (V ≥ 0.80), particularly in conceptual and pedagogical domains, while several technological and implementation indicators suggest the need for minor improvements. Overall, the instrument confirms that the AI-PjBL model is valid and feasible for implementation with slight revisions, providing strong evidence for its applicability in enhancing teachers’ digital literacy and AI readiness in educational settings
