<![CDATA[This study aims to design and validate an inquiry based instructional design for Basic Physics laboratories integrated with local context at the higher education level. The research employed a Research and Development (R&D) approach using the ADDIE model, limited to the stages of analysis, design, development, and expert validation. The developed products consisted of a student laboratory manual and a lecturer guide structured into pre-laboratory, in-laboratory, and post-laboratory inquiry phases, with local context positioned as a source of authentic physical phenomena and problem situations. Expert validation was conducted by instructional design experts, physics content experts, and learning media experts using a Likert scale based validation instrument analyzed with Aiken’s V coefficient. The validation results indicate that the instructional design demonstrates a high level of validity and feasibility across conceptual, material, and media aspects, confirming its suitability for use in Basic Physics laboratory learning. This study contributes a systematically validated instructional design framework for inquiry based physics laboratories that integrates local context as a core component of laboratory activities, providing a theoretically grounded and practically feasible design for future implementation and effectiveness studies]]>
