This article reports findings from the largest-ever randomized controlled trial of a growth mindset program in the United States in K-12 settings. The study combined a test for cause-and-effect (a randomized experiment) with a sample that enables claims about an entire population (a nationally representative probability sample). The study found that a short (less than one hour), online growth mindset intervention—which teaches that intellectual abilities can be developed—improved grades among lower-achieving students and increased enrollment in advanced mathematics courses among both higher- and lower-achieving students in a nationally representative sample of regular public high schools in the United States. Notably, the study identified school contexts that moderated the effects of the growth mindset intervention: the intervention had a stronger effect on grades when peer norms aligned with the messages of the intervention. In addition to its rigorous design, the study also featured independent data collection and processing, pre-registration of analyses, and corroboration of results by a blinded Bayesian analysis.

In this study the research team uses a nationwide sample of high school students from Chile to investigate how these factors interact on a systemic level. Confirming prior research, they find that family income is a strong predictor of achievement. Extending prior research, they find that a growth mindset (the belief that intelligence is not fixed and can be developed) is a comparably strong predictor of achievement and that it exhibits a positive relationship with achievement across all of the socioeconomic strata in the country. Furthermore, they find that students from lower-income families were less likely to hold a growth mindset than their wealthier peers, but those who did hold a growth mindset were appreciably buffered against the deleterious effects of poverty on achievement. These results suggest that students’ mindsets may temper or exacerbate the effects of economic disadvantage on a systemic level.

Previous experiments have shown that college students benefit when they understand that challenges in the transition to college are common and improvable and, thus, that early struggles need not portend a permanent lack of belonging or potential. Could such an approach—called a lay theory intervention—be effective before college matriculation? The lay theory interventions raised first-year full-time college enrollment among students from socially and economically disadvantaged backgrounds exiting a high-performing charter high school network or entering a public flagship university (experiments 1 and 2) and, at a selective private university, raised disadvantaged students’ cumulative first-year grade point average (experiment 3). These gains correspond to 31–40% reductions of the raw (unadjusted) institutional achievement gaps between students from disadvantaged and nondisadvantaged backgrounds at those institutions. Further, follow-up surveys suggest that the interventions improved disadvantaged students’ overall college experiences, promoting use of student support services and the development of friendship networks and mentor relationships.

Growing suspension rates predict major negative life outcomes, including adult incarceration and unemployment. The first experiment tested whether teachers could be encouraged to adopt an empathic rather than punitive mindset about discipline—to value students’ perspectives and sustain positive relationships while encouraging better behavior. The second tested whether an empathic response to misbehavior would sustain students’ respect for teachers and motivation to behave well in class. These hypotheses were confirmed. Finally, a randomized field experiment tested a brief, online intervention to encourage teachers to adopt an empathic mindset about discipline. Evaluated at five middle schools in three districts, this intervention halved year-long student suspension rates and bolstered respect the most at-risk students, previously suspended students, perceived from teachers. Teachers’ mindsets about discipline directly affect the quality of teacher– student relationships and student suspensions and, moreover, can be changed through scalable intervention.

There are many promising psychological interventions on the horizon, but there is no clear methodology for preparing them to be scaled up. Drawing on design thinking, the present research formalizes a methodology for redesigning and tailoring initial interventions. The researchers test the methodology using the case of fixed versus growth mindsets during the transition to high school. The current research provides a model for how to improve and scale interventions that begin to address pressing educational problems. It also provides insight into how to teach a growth mindset more effectively.

This paper was prepared for a White House meeting on academic mindsets in May 2013. The authors review recent research findings and put forth an R&D agenda focused on principles (understanding how to maximize the effects of mindset interventions); practices (expanding the toolkit of day-to-day practices that instill adaptive mindsets; and assessments (developing measures that allow for more rapid learning from practice).

The first study revealed that students with more of a pro-social, self-transcendent purpose for learning persisted longer on a boring task and were less likely to drop out of college. A second study showed that a brief intervention promoting a self-transcendent purpose for learning improved high school GPA. Two other studies showed that promoting a self-transcendent purpose increased deeper learning behavior on tedious test review materials and sustained self-regulation over the course of an increasingly boring task. More self-oriented motives for learning—such as the desire to have an interesting or enjoyable career—did not, on their own, consistently produce these benefits.

The authors delivered brief growth mindset and sense of purpose interventions through online modules to 1,594 high school students. Among students at risk of dropping out of high school, both of the interventions raised students' semester GPAs in core academic courses and increased the rate at which students passed their courses.
