In A Nutshell
- About half of students surveyed in introductory college physics reported feeling psychologically threatened by the course, with students from systemically excluded groups hit hardest.
- A five-day mindfulness audio program taught students to recognize and step back from stress without suppressing it, using a technique called R.A.I.N.
- Students who completed the training reported less psychological threat, lower anxiety, greater confidence, and a stronger sense of belonging in physics compared to a control group.
- Reduced threat levels were still measurable three months after the training ended, and the benefits held regardless of students’ race, gender, or identity group.
Introductory physics courses don’t just test students on equations and exams. For about half of the students surveyed in a new study, these classes also trigger a deep sense of self-doubt, a gnawing worry that they simply aren’t cut out for the material. Researchers now report that a brief round of mindfulness training, just five days of 20-minute audio lessons, can reduce that emotional burden and improve some signs of engagement, including confidence, anxiety, and belonging. Some effects, including reduced psychological threat, were still visible three months later.
Published in the Proceedings of the National Academy of Sciences, the work was led by researchers at the University of Pittsburgh and the University of Illinois Urbana-Champaign. It points to a surprisingly simple tool for addressing one of the biggest, and most overlooked, barriers in introductory science courses: the emotional toll they take on students, particularly those from groups historically underrepresented in physics.
Half of Surveyed Physics Students Report Feeling Psychologically Threatened
Researchers started with a basic question. How do students experience stress in introductory physics? Using a well-established framework from psychology, when people face a stressful situation, they weigh how demanding it feels against how well they think they can cope. When demands feel overwhelming and a student doesn’t believe they have the tools to handle them, researchers call that “psychological threat.” When a student feels stressed but confident they can rise to the occasion, that’s a healthier state tied to motivation and better performance.
To measure how widespread threat was, the team surveyed 954 students enrolled in 11 sections of calculus-based introductory physics at a large public university in the Mid-Atlantic region. About half reported feeling psychologically threatened by the course.
Students the study described as belonging to systemically excluded groups in physics, meaning students of color across gender identities as well as white women and nonbinary students, were more likely to report threat. About 59% of those students felt threatened, compared to roughly 39% of white men. These gaps echo longstanding research showing that stereotypes and competitive classroom cultures can worsen self-doubt among underrepresented students in STEM.
Five Days of Mindfulness Training Changed How Stressed Physics Students Coped
With that data in hand, researchers recruited 149 students who had screened as psychologically threatened for an experiment. Participants were randomly split into two groups, one receiving mindfulness training and the other listening to audiobooks, so the researchers could compare effects head to head.
Mindfulness participants listened to five 20-minute audio lessons over a single Monday-to-Friday week. Lessons walked students through a practice called R.A.I.N., short for Recognize, Accept, Investigate, and Non-Identify. Students were guided to recall a difficult physics experience, say, bombing a test or feeling lost during a lecture, notice the emotions it stirred up, accept those feelings without judgment, and then step back from them, recognizing they were temporary and didn’t define who the student was. Before building the training, the research team conducted hour-long interviews with students to identify their specific concerns. Common worries included social comparison with classmates, exam anxiety, and frustration over not understanding the material, and lessons were built around those real-world stressors.
The comparison group listened to two 20-minute short stories. During the middle three days, all participants completed brief surveys twice daily measuring psychological threat. Both groups also completed longer surveys at the start of the training week, at the end of it, two weeks later, and three months later.
Mindfulness Boosted Physics Students’ Belief That They Could Handle the Course
Students who received mindfulness training reported lower psychological threat during the training week compared to the audiobook group. More telling, those reductions didn’t fade quickly. At the two-week follow-up and even three months later, mindfulness participants still reported less threat.
When researchers examined what drove the change, they found something worth noting. Mindfulness didn’t reduce how demanding students perceived physics to be. The course was still hard, and participants knew it. Instead, training boosted students’ sense of their own ability to cope. It helped students believe they were better equipped to handle the material.
Students in the mindfulness group also reported greater confidence, lower anxiety, and a stronger sense of belonging in physics. Further analysis confirmed these gains were partially driven by the reductions in threat itself. Other measures, such as interest in physics or study habits, were largely unchanged, consistent with the team’s predictions.
A Physics Equity Approach That Targets Stress, Not Identity
Rather than targeting students based on race or gender, researchers targeted a psychological process: the experience of threat. Because students from systemically excluded groups were more likely to feel threatened, they naturally made up a larger share of the experiment, about 72% of participants. But the training was designed for anyone struggling with the emotional weight of physics, and social identity did not change how effective it was.
Introductory physics is a gatekeeper course. Passing it is required to declare majors in engineering and the physical sciences. When students pull back because the emotional toll feels too high, it can quietly redirect entire academic paths. A brief, accessible intervention that helps students stay engaged may offer something worth building on, echoing the Winnie the Pooh line quoted by the researchers, that students can be “braver than they believe, stronger than they seem, and smarter than they think.”
Paper Notes
Limitations
Conducted at a single large public R1 university in the Mid-Atlantic region, the study’s findings may not transfer to other types of institutions or to non-Western student populations. Researchers noted that physics faculty at the study site were particularly open to curriculum innovation and research engagement, conditions that may have been unusually favorable to the intervention. Because participants were specifically screened for psychological threat, the findings don’t speak to how mindfulness training might affect students who already feel equipped to handle their coursework. Additionally, the audiobook comparison was passive, meaning the study cannot rule out all alternative explanations, such as increased relaxation from simply listening to audio content, though prior evidence suggests that audiobook and reading experiences can also reduce stress. Participants were also motivated enough to enroll in an intensive research study, which may not reflect the broader introductory physics population. Replication in other STEM courses and at other institutions remains an important next step.
