 Hi, I'm Keon, a member of the wire team and a co-author of Wheel of Sources. Wheel of Sources is the result of a long process of making prototypes and receiving feedback. We began this process by doing a four-paths to rapid brainstorming activity with stakeholders. In four minutes, each of us came up with four different approaches to helping students with the learning outcome. Our ideas ranged from animated videos to handouts to infographics to board games. After some discussion, we decided to make both a handout and an online interactive game. We made our first prototype using MIT's Scratch, a programming language designed primarily for kids. This initial prototype helped us clarify the layout of the game without getting bogged down by coding challenges. We created the second prototype by drawing out the entire game on index cards. This allowed us to focus on the content of the game without wrestling with technology. Prototyping on paper is something we do all the time. It helps us narrow our focus on content and not let technological limitations get in the way of student learning. However, we also try to keep our paper prototypes within the scope of the software we have available to us. After another round of feedback, we reworked all the examples and wrote the script for the game show. Now that the layout and content of the video were finalized, we could finally begin designing on the computer. This process allowed us to minimize the hassle of making edits to a polished product since most of the important edits were already made in earlier rounds of feedback. We hope this helps!
