Some students said they stumbled upon the videos whilesearching for any online resources, while other students reported discovering the resourcethrough word-of-mouth (classmates or instructors). They expressed the need for frequentreminders by faculty that ME Online exists, especially when students are in their early years inthe program. One student noted: “When I first learned about the videos, I think it was, like, the end of my second year or early third year, and I remember looking at all of the videos there.

It begins with students individually identifying problems and drafting needstatements [27] for a problem they would want to work on over the course of the semester. Oncestudents individually identified need statements, students would then pitch their statements as aone-minute elevator pitch to the class and then would be given time to self-create teams of fiveto six individuals per team.

related to the outcomes of fluency and elaboration, but not reflection.IntroductionOne of the most timely and pressing goals of promoting early STEM education is to createeducational experiences that will both broaden enduring participation in the study of STEMtopics [1] and that will establish a long-term learning framework to encourage students to trainfor important STEM careers [2]. In the field of engineering education, this idea is bound up inmetaphors like those of “the pipeline”, “the ecosystem”, and “the pathways” [3,4], all of whichinclude a multitude of diverse trajectories in the course of study and skill development wherebystudents can access their opportunities to become expert engineers [5].There are many ways in which pre-college

Until designpractices are fully integrated into engineering curricula, capstone design programs will bear asubstantial burden to better prepare undergraduates for careers that inevitably emphasize the“practice” of design.At RIT, the infusion of multidisciplinary design into the curriculum represents a strategicimperative for the KGCOE.
