The Invention Toolkit is a framework created by Oregon MESA and constructed to facilitate invention creation through project-based learning. This tool was made by in-school and out-of-school educators as a resource for all educators. In the Invention Toolkit, the teacher is viewed as a facilitator of learning to help students work through developing empathy for a client, defining the problem through the clients’ lens, ideating and evaluating possible solutions, building and testing a prototype which meets a set of criteria and constraints, and presenting their process with a focus on identifying challenges and describing how those were overcome to create their working prototype.
