Subclaims¶

q3 i? In a nationally representative double-blind clinical trial with 8,775 9th-graders and 223 math teachers, the growth mindset intervention lowered fixed-mindset beliefs for all intervention students, but only students taught by growth-mindset teachers showed significant math-grade improvements. → Fitz 2025 q2 i? Meta-analyses find economically disadvantaged and academically high-risk students benefit from growth mindset interventions even though effects on the overall population are weaker and debated. → Fitz 2025 (2)

q3 · i? · review · r2

David Yeager and colleagues' nationally representative double-blind clinical trial of 8,775 9th-graders and 223 math teachers: only intervention students with growth-mindset teachers showed significant math-grade gains; no differences for fixed-mindset teachers' students.

"however, when their math grades were examined later in the year, only the intervention students who were taught by a math teacher who espoused a growth mindset exhibited significant improvements to their math grades. The study found no differences between intervention and control group students whose teachers espoused a fixed mindset."

q3 · i? · review · r2

The review reports that meta-analyses find benefits concentrated among "economically disadvantaged and academically high-risk students," with weaker overall-population effects and continuing debate about intervention strength.

"While the strength of the relationship between growth mindset interventions and academic achievement continues to be debated,91 meta-analyses find evidence that economically disadvantaged and academically high-risk students tend to benefit from these interventions, even if the effects on the overall student population are weaker."

Discussion¶

Learner Variables¶

• Socioeconomic Status — moderator: an instructional effect differs by group
• Mindset — moderator: an instructional effect differs with it

Related Claims¶

• Effects were larger in intervention schools with a higher percentage of economically disadvantaged students or a lower percentage of White students — the general claim this finding bears on, with the studies behind it
• Growth-mindset interventions have weak average effects on achievement, including a negligible GPA gain (d = 0.11) for lower-achieving US ninth-graders in one preregistered national trial — related
• Aronson et al. (2002) pen-pal growth mindset intervention produced a statistically significant positive effect on quarter GPA (effect size 0.85) — related
• Teachers who are effective at improving academic behaviors and mindsets are often not the same teachers who raise math test scores — related
• The growth mindset intervention increased tenth-grade advanced mathematics course enrolment overall, with larger gains in the highest-achieving schools — related
• A short online growth mindset intervention improved ninth-grade core-course GPAs among lower-achieving students in a nationally representative US sample — related
• Mind-set interventions show weak overall effects on achievement, with some support that low-SES or academically at-risk students might benefit — related
• Growth math mindset positively predicts academic grit in primary students — related
• Brief online growth-mindset interventions produce modest academic gains concentrated among students at risk of underperformance — related
• Fixed mindset correlates negatively with GPA among U.S. 9th-grade students (average r = −.22) in a nationally representative sample — related
• In Study 1, the revised growth mindset intervention reduced choosing easy over hard math problems more than the original intervention (d=.19) — a narrower finding that bears on this claim
• The growth mindset intervention successfully fostered mindset beliefs but this did not transfer to learning outcomes — related
• When delivered by master's students, the intervention additionally improved growth mindsets and standardized math achievement — related
