"Making" has been used to describe an internally motivated iterative design process that embodies notions of playful building and tinkering. Recently, interest in applying making to PK-12 education has increased. As schools add facilities dedicated to making, there is a need to support teachers in effectively utilizing these makerspaces. UTeach Maker is a microcredentialing program that supports preservice teachers interested in bringing making into STEM (science, technology, engineering, and mathematics) classrooms and PK-12 makerspace environments. This article describes UTeach Maker and articulates success factors. These factors include a Maker Showcase framework, community support, and the public review and presentation of work in both digital and face-to-face formats. Challenges encountered in the program's first year and future steps are also discussed.
