This paper introduces Educational Conceptual Model Design a new research methodology to develop conceptual models in the field of educational technology. It is based on principles from Conceptual Design Methodology, Conceptual Modeling Methodology, Design-Based Research, and Design Science Research. It is a systematic methodology structured in four phases: problem definition, conceptual foundation, model development, and knowledge contribution. This methodology is designed to be streamlined and grounded in theory, focusing on consistency, replicability, and alignment with theoretical rigor. The methodology is particularly suited to respond to rapid advancements in technology and continuously evolving educational challenges, including the integration of emerging tools such as Artificial Intelligence in Education. Its main characteristic is that it offers a transition from problem identification to practical models with a special emphasis on the design process. This approach reduces the complexity of developing a model while maintaining its applicability across different educational technology areas, which can range from adaptive learning systems to data-driven learning analytics. The paper concludes by discussing the methodology’s contributions to theory and practice, its limitations, and potential future directions, including scalability, cross-disciplinary integration, and the incorporation of disruptive technologies. This methodology serves as a foundational framework for researchers and practitioners aiming to design innovative forward-thinking solutions that meet the dynamic needs of modern education.
