Offering more science, technology, math, and engineering (STEM) courses in high school doesn’t increase the number of students’ interest in those majors in college, according to a new study by the University of Kentucky and University of Missouri.
Interest in STEM begins much earlier–as early as third grade, and emphasizing it those courses high school could miss the critical window of opportunity. From The 74 Million:
The study, conducted by the University of Kentucky’s Rajeev Darolia and the University of Missouri’s Cory Koedel, compared academic records for 140,000 students in Missouri public colleges between 1996 and 2009 with data on course offerings in the roughly 500 Missouri public high schools they graduated from.
Since students who declare a STEM major or graduate with a STEM degree generally enrolled in more STEM courses as teenagers, some have suggested that offering more of those courses in high schools could attract more students and prepare them to succeed in the subjects at the post-secondary level. In schools with high percentages of low-income or minority students, it is hoped that expanding STEM course access could yield pathways for underrepresented students to lucrative careers.
The results from Missouri’s schools don’t support that theory. While the number of STEM majors at Missouri’s 14 public colleges and universities increased modestly over the period Darolia and Koedel studied, the number of STEM courses offered in high schools was about flat — and the number of science courses actually declined.
Overall, students who attended high schools with broader STEM offerings were hardly more likely to major (or attain a college degree) in a STEM subject than those whose high schools offered fewer such courses. The authors estimate that offering one more STEM course per 100 students would increase college STEM enrollment and degree attainment by between .03 and .04 percentage points.
What’s more, increasing access to STEM classes for female and minority students in high school doesn’t help them catch up to white and Asian men later on. It could even make those groups fall further behind.
“The estimates suggest that post-secondary STEM outcomes for female and underrepresented minority students are less affected by access to STEM courses in high school than white male students,” they write. “The implication is that broad, untargeted efforts to expand STEM access in high school may modestly exacerbate current race- and gender-based imbalances in STEM fields.”
Darolia and Koedel conclude by suggesting that improving the pool of STEM teachers, instructional methods, or curricular materials might be better paths to improvement than simply expanding access to existing resources. But it’s also possible that the academic inclination toward math, science, and technology is simply activated earlier in children’s schooling.
In a highly publicized study from late 2017, renowned economist Raj Chetty demonstrated that children who later go on to become inventors were typically already performing well on third-grade math tests. They were also much more likely to come from high-income families, especially when one of their parents was also a patent holder.
If childhood exposure to technological innovation is the most important factor in later-life technical success, offering more STEM classes to high schoolers simply might not make much difference.
