With support from the Improving Undergraduate STEM Education: Hispanic-Serving Institutions (HSI Program), this Implementation and Evaluation Project aims to improve how students learn and stay engaged in mechanical engineering courses at the University of New Mexico. The project introduces the idea of organizational citizenship behavior into the classroom, meaning that it encourages students to go beyond just doing their own work to help each other, much like good teammates in a workplace. Engineering students often gain strong technical skills, but they perform even better when they feel welcome and supported by their classmates. This project will create learning environments where students are encouraged to work together, share ideas, and support one another. Such interactions can improve motivation, build confidence, and strengthen students’ connection to engineering. This project will design activities that promote collaboration and peer support. Through structured learning activities, the project will demonstrate how cooperative behaviors, such as sharing ideas, offering encouragement, or assisting classmates, can lead to improved student learning, greater confidence, and a stronger connection to the engineering field. The expected outcomes of this project are to help all students succeed by creating supportive, collaborative classrooms and developing teaching and learning strategies that can be shared widely to prepare students for their engineering careers.
