In some ways, DeLean Tolbert鈥檚 life at 萝莉社-Dearborn looks a lot different today than it did when she was an undergraduate here. For starters, there鈥檚 the obvious: Thirteen years ago, she was a student in an intro to engineering course; this semester, she鈥檚 teaching it 鈥 an experience the second-year industrial and manufacturing systems engineering assistant professor candidly admits still feels 鈥渁 little crazy.鈥
But there鈥檚 also plenty of continuity to read between those two chapters of her 萝莉社-Dearborn story. In fact, the complex research questions Tolbert is wrestling with now 鈥 which center on race, engineering skill development and access to higher education 鈥 are things she started wondering about when she was a student. The spark came during her senior year, while deep into an independent study with Electrical Engineering Professor Paul Watta. Officially, the project focused on exploring new learning tools for the intro to engineering course; but in the process, she also bumped into some interesting trends and questions about her fellow engineering students.
鈥淏ack then I noticed if, say, 10 African-American or underrepresented minority students started freshman engineering with me, just a handful of us would still be around by senior year,鈥 Tolbert says.
And when she pushed a little deeper into university data, she discovered the retention challenges were larger for African-American students. 鈥淚t, of course, gets you wondering why that is, and if there were things you could do to better support students at key points in their careers, maybe the outcomes would be better.鈥
She鈥檚 still deep down that rabbit hole of inquiry; though today, the platform for investigation is more robust. Tolbert occupies a unique place in the College of Engineering and Computer Science 鈥 an engineer who is, by training and curiosity, just as much a social scientist. A case in point is her current research study, which involves identifying the pathways by which students from demographic groups who are underrepresented in engineering disciplines end up studying engineering at the university level.
鈥淔or example, one question we鈥檙e interested in is the relationship between the students we recruit and the zip codes they come from in terms of technology usage,鈥 Tolbert says. 鈥淒etroit is a place where there is very uneven internet access, so we鈥檙e interested to see if that could be a factor in whether those students go on to college.鈥
Mapping such trend lines could lead to new ideas for how to better support students from under-resourced communities. One example Tolbert has been inspired by lately are neighborhood 鈥渕aker spaces鈥 鈥 creative hubs where kids can 鈥渢inker, build, fix and break things.鈥 Having more opportunities like that, she said, could help ignite students鈥 interest in engineering early on.
Such ideas almost prompt provocative conversations about what 鈥渃ounts鈥 as an early engineering experience. Traditionally defined, that might include things like participation in a robotics program, activities that are common among students from better-resourced communities.
鈥淏ut what if you鈥檙e fixing the lawnmower with your grandfather? Or helping your mom pay the bills? That requires a lot of math and critical thinking,鈥 Tolbert says. 鈥淭hose are valid experiences too, but we need to encourage students to see them that way.鈥 On the institutional side, she said, that could also mean exploring reforms to admissions policies at engineering schools, so that they鈥檙e more inclusive of different types of experiences.
Tolbert knows those are larger college-level, even institutional-level, conversations. But her deep dive into these questions fits right into the current push to make the College of Engineering and Computer Science a more inclusive space. In the past six years, under the leadership of Dean Tony England, the percentage of women students enrolled in the college has climbed from 11 percent to 19 percent, while the number of women faculty shot up from just two to 11. And the college鈥檚 near peer mentoring program is connecting 萝莉社-Dearborn engineering undergrads with middle and high school students in under-resourced metro Detroit schools. It鈥檚 a big part of the reason CECS took home the University of Michigan鈥檚 Rhetaugh G. Dumas Progress in Diversifying Award last year.
As Tolbert contributes to those larger efforts to reshape the college, she鈥檚 also doing what she can now in the classroom. One of her first-week exercises for students in her intro to engineering course is filling out a personal questionnaire, which helps her build more diverse student teams. Then, she chases that with a lecture about how cultural bias can influence engineering and design on a very basic level.
鈥淚 share with them the example of bathroom soap dispensers that had sensors that wouldn鈥檛 activate with darker skin on the backs of people鈥檚 hands, but would when they flipped their hands over to expose the lighter-colored palms. Or the Ford Windstar, which didn鈥檛 sell well until it was redesigned by a team of women engineers to meet women鈥檚 needs that were ignored in the previous design. That鈥檚 intended to show the students that this is not just a justice or an equity issue. It demonstrates that we do engineering poorly when we don鈥檛 have many voices at the table.鈥
