Beyond pipeline and pathways: Ecosystem metrics

Abstract

Abstract Background Pipeline and pathways models influence persistence metrics used to study how students navigate engineering education. Purpose This study presents pipeline, pathways, and ecosystem models and their associated metrics, compares and contrasts these models using an intersectional approach to explore persistence, and advocates for use of an ecosystem model. Design/Method This study presents a quantitative perspective of engineering student outcomes disaggregated by discipline, race/ethnicity, and sex. It includes 111,925 engineering students from 11 U.S. universities, including first‐time‐in‐college and transfer students who ever majored in the most common engineering disciplines: chemical, civil, electrical, industrial, and mechanical engineering. Contemporary data visualization methods are used to display quantitative data and clarify their complexity. Results This work captures the intersectionality of race/ethnicity, sex, and discipline with metrics that are new or little used, such as stickiness (retention by a discipline), migrator graduation rate, and migration yield (attraction of a discipline). Using these metrics, we uncover information about the success of students who migrate between and among the top five engineering disciplines. Conclusions Stickiness, migrator graduation rates, and migration yield metrics coupled with contemporary data visualization methods provide insights into the student experience not afforded by the conventional pipeline and pathways models. Considering engineering education as an ecosystem tells stories of complexity and nuance, opening possibilities for new research.
