Study: diverse college classrooms linked to better STEM learning outcomes for all students

Underrepresented racial minorities and first-generation students show the most improvement

2023-12-06

(Press-News.org) Washington, December 6, 2023—Students achieve better grades in college science, technology, engineering, and math (STEM) courses when those classrooms have higher numbers of underrepresented racial-minority and first-generation college students, according to new research released today. The findings were published in AERA Open, a peer-reviewed journal of the American Educational Research Association.

While this link holds true for all students, it is even stronger for students who are underrepresented racial minorities (URMs) and the first in their family to attend college. The authors found that in STEM courses with higher URM representation, the gap in grades between URM and non-URM students dropped by 27 percent. More impressive, the grade disparity between first-generation and continuing-generation students dropped by 56 percent in STEM courses with high first-generation representation.

Racial and socioeconomic disparities in college grades and graduation rates have been long-standing concerns in STEM programs, especially given the nation’s pressing need to grow its STEM workforce and the higher salaries that these graduates earn. In addition, the authors emphasize that all students benefit from the presence of URMs and first-generation students in the classroom.

“It’s really notable that improving racial and socioeconomic representation leads to benefits for everyone and reduces inequities at the same time,” said study coauthor Nicholas Bowman, a professor of educational policy and leadership studies at the University of Iowa. “It is not a zero-sum game.”

Bowman conducted the study with Christine Logel (Renison University College), Jennifer LaCosse (University of Michigan–Flint), Elizabeth A. Canning (Washington State University), Katherine T. U. Emerson (Indiana University), and Mary C. Murphy (Indiana University). Their study analyzed data collected by the College Transition Collaborative, covering 11,868 undergraduates in 8,468 STEM courses at 20 U.S. colleges and universities from fall 2015 to summer 2017.

With the Supreme Court eliminating the use of race-conscious college admissions last June, the authors note their findings make clear what is at stake for students as institutions of higher education look to alternative ways to increase racial and socioeconomic representation.

“It is critical that colleges and universities redouble their efforts to create learning environments that have substantial diversity,” said Bowman. “This is especially true in the STEM fields, where there are long-existing equity gaps.”

Bowman noted the study is the first on this topic to use such a large, multi-institutional data set. It is also one of the first to examine the role of classroom representation of first-generation students. In addition, the authors accounted for potential student self-selection into certain types of courses or into classes with demographically similar peers and other possible explanations.

“The consistency of results across student and course characteristics drives home the importance of our results,” said Bowman. “Despite the presence of long-standing systemic inequities, policies that promote college access for URM and first-generation students can make a difference when it comes to improving learning outcomes.”

Repeated blast exposures may harm the brain health of military personnel

2023-12-06

The brains of special warfare community personnel repeatedly exposed to blasts show increased inflammation and structural changes compared with a control group, potentially increasing the risk of long-term, brain-related disease, according to a new study. Researchers from the University of Virginia School of Medicine and Naval Medical Research Command (NMRC) led the study, which compared the brains of nine special operations personnel exposed to blasts with a control group of nine military service members with only minimal exposures to blasts. Participants’ brains were analyzed using sophisticated imaging techniques, combined with surveys ...

New findings reveal important insights into age-related nonresolving inflammation

2023-12-06

Philadelphia, December 6, 2023 – Aging is associated with chronic, nonresolving inflammation, or “inflammaging,” that can lead to tissue dysfunction. New findings reported in The American Journal of Pathology, published by Elsevier, reveal insights into the cellular programs and factors that promote the resolution of inflammation during aging. These findings may lead to the development of new strategies to limit age-related organ decline. The resolution of inflammation is an active process that is governed by numerous factors, such as specialized ...

Model uses sociodemographic factors to predict aromatase inhibitor non-adherence risk

2023-12-06

A new risk model uses baseline sociodemographic and financial measures to predict which patients prescribed long-term therapy with aromatase inhibitors for breast cancer are at significantly higher risk of stopping that therapy early (non-adherence). The work will be presented in a poster spotlight discussion session at the 2023 San Antonio Breast Cancer Symposium (SABCS) on Wednesday, December 6th. The authors analyzed data from the SWOG S1105 clinical trial, including measures of patient adherence to aromatase inhibitor (AI) therapy for hormone-sensitive breast cancer. They created a model ...

NIH awards $9 million for Indigenous-led Tribal Data Repository to improve community health in response to COVID-19 pandemic

2023-12-06

In an effort to improve the health of Tribal communities and Indigenous people, the National Institutes of Health (NIH) has awarded $9 million in funding for Native scientists at Arizona State University and elsewhere to create the first Indigenous-led Tribal Data Repository. Since the SARS-CoV-2 worldwide pandemic began, global Indigenous communities have been particularly hard hit, with health disparities including lack of access to health care and undue burden of infections leading to increased hospitalizations and higher death rates. In response, Indigenous researchers and scientists have been working to secure and fund efforts to better understand the impact of COVID-19 and ...

Fascicle gearing dynamics: Unveiling 3D rotation effects in muscle elongation

2023-12-06

Detailed insights into muscle and tendon movement mechanisms during stretching are essential to improve our overall mobility and flexibility. It is not only important for optimum athletic performance, but also crucial for preventing musculoskeletal injuries. When an individual stretches, 50% to 70% of the elongation is absorbed into the muscle belly, i.e., the fleshy part of the muscle containing most fibers. However, in skeletal muscles with fascicles, the muscle fibers are shorter than the muscle belly and attach to the tendon at an angle. This angle between the fascicles and the tendon changes in response to the length of the muscle belly ...

Greenhouse gases in oceans are altered by climate change impact on microbes – an Incheon National University study

2023-12-06

The ocean is a critical life-support system for our planet through its role in global climate regulation. It absorbs most of the carbon emissions and heat trapped in the atmosphere which are a result of human activities. Over the years, this has led to ocean warming (OW), ocean acidification (OA), and ocean deoxygenation (OD). Moreover, increased anthropogenic‑nitrogen-deposition (AND) has largely influenced marine environments. As part of these consequences, the gases nitrous oxide (N2O) and methane (CH4) are largely controlled by 'prokaryotes’ or microbial organisms living in the ocean. While several studies have analyzed ...

New study finds many couples around the world may share high blood pressure

2023-12-06

Research Highlights: A study of married or partnered, middle-aged and older heterosexual couples in the U.S., England, China and India found that in 20% to 47% of the couples, both spouses/partners had high blood pressure. The prevalence of both spouses/partners having high blood pressure was highest in England and the U.S., however, spouses/partners whose spouses/partners had high blood pressure were more likely to also have high blood pressure in China and India. Researchers suggest couple-based interventions to improve high blood pressure diagnosis and management, such as couple-based screening, skills training or joint ...
