“…MIDFIELD is an excellent database for conducting longitudinally-designed studies on trends in engineering education, as the database contains a sample of 1,014,887 undergraduate students from 11 different participating institutions (Ohland & Long, 2016). This database has been used to explore such topics as nontraditional student pathways to the engineering degree (McNeil & Ohland, 2015), age differences (McNeil, Long, & Ohland, 2014), and student socioeconomic status (Orr, Ramirez, & Ohland, 2011;McNeil & Ohland, 2015), to name a few. The MIDFIELD database comprises approximately 10 percent of all engineering graduates from U.S. institutions that attended between 1988 and 2009.…”
