From food production to processing to distribution, food systems are an integral part of the local, regional, and national economy. These systems also drive STEM innovation and require interdisciplinary actions from across STEM fields. The need for STEM-related food system jobs shows the importance of high school youth exploring related STEM careers and developing skills to solve complex food system problems. At the same time, technology in K-12 education often centers on the use of technology, rather than understanding the role of technology in complex STEM systems. The Internet of Things, such as smartphones, sensors, and remote-control systems, includes digital technologies that can help students learn how to use technology to collect and manage digital data and actively use data to make decisions. Building on the outputs and outcomes of previous USDA investments, this project will design and study professional development and curricula that (1) advance urban high school STEM teachers' enactment of learner centered teaching; (2) support urban high school students' design thinking using the Internet of Things to solve incubation design challenges; and (3) develop students' connections to local STEM workforce opportunities through community and scientist partnerships. This project will directly impact 11 urban high school teachers and 2,020 students attending 5 urban high schools by supporting students' STEM knowledge, problem-solving skills, design thinking with the Int
