"I'm just not a math person." Every teacher has heard some version of it by second grade. Growth mindset is the belief that abilities can be developed through effort, good strategies and help from others, and it is one of the most popular ideas in schools. It is also one of the most misunderstood.
Where the idea comes from
Stanford psychologist Carol Dweck and colleagues spent decades studying how students explain success and failure. Students who see ability as fixed tend to avoid challenges and give up after setbacks; students who see ability as something that grows tend to try new strategies and persist. Dweck's 2006 book Mindset brought the idea to millions of teachers and parents.
What later research found
Large studies have refined the picture. A national experiment in the United States, published in Nature in 2019, found that a short online growth mindset programme modestly improved grades for lower-achieving high school students, especially in schools whose culture supported challenge. Meta-analyses have found that average effects across all students are small. The take-away for elementary teachers is not that growth mindset is useless, but that posters and slogans are not enough. What matters is how the classroom treats mistakes, effort and strategy every day.
Avoid "false growth mindset"
Dweck herself has warned against a false growth mindset: praising effort alone ("You tried so hard!") even when a child is stuck, or telling students "anyone can do anything". Effort without a better strategy just leads to frustration. Effective growth mindset feedback connects effort, strategy and progress.
| Instead of... | Try... |
|---|---|
| "You're so smart!" | "You checked your work and found the mistake. That strategy paid off." |
| "Good effort." | "You've been working hard. Let's look at another way to try it." |
| "Don't worry, math isn't your thing." | "This is hard right now. What could help: a drawing, a number line or a partner?" |
| "It's easy!" | "This one might feel tricky. Tricky means your brain is learning." |
| "Wrong." | "Not yet. What did you notice about where it went off track?" |
Classroom routines that build it
- The power of yet. When a student says "I can't do it", add "yet" and ask what the next step is.
- Favourite mistake. Once a week, share a mistake (yours or, with permission, a student's) that taught the class something. Normalising mistakes is the core of the idea.
- Before and after. Keep early work samples and compare them with later ones. Seeing their own progress is more convincing than any slogan.
- Strategy menus. Post "What to do when I'm stuck": reread, draw it, try a smaller number, ask a friend, ask the teacher.
- Brain growth talk. Explain simply that practising something hard helps the brain build stronger connections, the way exercise builds muscles. Keep it a metaphor, not a neuroscience lecture.
A five-minute growth mindset activity
Read a short scenario: "Maya tried to ride her bike without training wheels and fell three times." Ask: What might Maya say to herself if she thinks she can't learn? What might she say if she thinks she can? What could she try differently? Then ask students to share one thing they could not do last year that they can do now.
Connect it to goals: growth mindset is most powerful when students set a small goal and plan for obstacles. See goal setting and time management for kids.
