Prior to initiating the design phase, I interviewed three middle and high school teachers with expertise in physics, humanities, and Maker education. A prevailing theme emerged among subject teachers, revealing their time constraints and perceived challenges in designing interdisciplinary lessons. The Maker educator expressed the need for a more structured introduction for new teachers entering the realm of interdisciplinary learning. Subsequently, after completing the initial draft of the online module and teacher guide, I conducted user testing with four teachers. I made revisions based on their behavior, questions asked, and feedback as they navigated through the module and the guide. The module now features optional sections, the guide is more concise, and additional clarifications are incorporated based on user behavior and input, ensuring the resources align effectively with educators' needs.
