This project team will develop and test a prototype an online platform to facilitate engineering project challenges within K–12 classrooms across many schools. The prototype will include a content management platform to enable a high volume of challenges for students to conduct projects on a broad range of STEM topics, such as computer coding, digital modeling, or producing simulations. In a pilot study with one school, the researchers will examine whether the prototype functions as planned, whether teachers are able to incorporate challenges within instruction practice, and if multiple classrooms are able to participate in a challenge and produce a product that in response to a challenge.
