In Simple Words
Think of a child's brain like a muscle that grows stronger each time it lifts a heavy weight rather than a fixed box with a set capacity. When teachers replace static praise ("you are so smart") with effort-focused feedback ("you worked really hard on this problem"), students stop viewing failure as a sign of permanent inadequacy and begin treating setbacks as temporary hurdles that can be cleared with more practice.
Fourth graders in 16 Istanbul schools
- Usual school activities
- Comparison group
- Grit curriculum
- Higher math test scores
Sample B, January 2016: gain of 0.28 standard deviations. The whole autumn curriculum was tested, not each lesson separately.
See source →Research question
Standard educational systems often treat non-cognitive skills like perseverance as fixed traits, leaving children from low socio-economic backgrounds without structured mechanisms to overcome academic setbacks.
Participants
N = 2,900 students across two independent state elementary school samples (Sample A: N = 1,717 students in 64 classrooms across 36 schools; Sample B: N = 1,203 students in 42 classrooms across 16 schools) in Istanbul, Turkey, aged 8–10 years.
Study Design
Randomized Controlled Trial (RCT) evaluated across state elementary schools with baseline and follow-up standardized tests and incentivized real-effort experimental tasks.
Results
Treated students scored 0.28 standard deviations higher in standardized math tests (p = 0.008) and 0.13 standard deviations higher in standardized Turkish tests (p = 0.027) at follow-up, while self-reported belief in skill malleability and perseverance both increased by approximately 0.30 standard deviations (p < 0.01).
Takeaway
Train elementary teachers to deliver effort-focused feedback and animated case studies during extracurricular hours to reframe student setbacks as opportunities for skill accumulation.

- Follow-up
Collecting more information about participants later in a study to see what has happened to them. The term can also mean the length of time researchers keep track of them.
ExampleResearchers interview the same workers three months after a programme ends. That later interview is a follow-up.

The starting measurements in a study. Researchers use these to compare what participants were like at the start with what happens later.
ExampleBefore a training programme starts, researchers measure workers’ earnings. That first measurement is the baseline.
GET-IT glossary · Baseline characteristics ↗Read more about baseline →- Randomized controlled trial
A study that uses chance, like drawing lots, to decide who receives each option being compared. Researchers compare the groups’ outcomes to estimate the effect of those options.
ExampleA lottery assigns volunteers to a training programme or a comparison group. Researchers then compare their outcomes.
