In order for students to perceive themselves as future STEM professionals and persevere in rigorous STEM courses, they must develop a STEM identity. MCESA in collaboration with multiple Arizona 100kin10 partners is supporting science educators in redesigning classroom experiences to address factors identified by research that contribute to STEM identity development. The Engineering STEM Identity (ESI) program utilizes video-conference interactions with STEM Professionals who become STEM Role Models for middle school classrooms and engages students in STEM authentic project-based learning using the Engineering Design Process. The STEM Professionals act as consultants and support both students and teachers in solving a school or community need. Research factors support the model in developing STEM Identity for middle school students.
