Incorporating digital technologies is essential in blended learning contexts to enhance conventional instructional approaches. This study aims to develop a Web-based Inquiry Physics Problem (WIPPer) as an interactive learning medium in a blended environment for the physics learning process. This study employs research and development approaches, applying the ADDIE approach to the development stage. The initial research step analyzes the physics learning demands of the web using literature and field investigations. The last phase of the development process involves producing a WIPPer product prepared for evaluation by materials, media, and instructional design experts, together with two high school physics teachers who will act as practitioners. Expert and practitioner assessments employ tools that evaluate material, media, and learning design. Expert and practitioner evaluation data were analyzed using the Aiken V algorithm. WIPPer had an Aiken V score of 0.867 from material and learning design experts and 0.805 from experts in media, indicating that experts deemed it highly valid. The results emphasize the potential of WIPPer as a beneficial tool for instructors who want to enhance physics training in blended learning contexts. It promotes more profound knowledge and active engagement among students.
