A secondary school in England carries out a hypothetical replication of Blackwell et al.'s (2007) intervention with 120 pupils. The pupils are randomly allocated to two eight-week workshops. The intervention group is taught that learning changes the brain, while the control group is taught about memory.
The pupils complete a growth-mindset questionnaire and a maths test before and after the workshops. Their maths teachers also rate their motivation without knowing which workshop each pupil attended. Higher scores indicate a stronger growth mindset, better maths performance or greater motivation.
| Measure | Intervention group before | Intervention group after | Control group before | Control group after |
|---|---|---|---|---|
| Growth-mindset score, out of 40 | 24.0 | 30.0 | 24.5 | 24.0 |
| Maths score, out of 100 | 61 | 68 | 62 | 60 |
| Teacher motivation rating, out of 5 | 3.1 | 3.9 | 3.2 | 3.0 |
