Growth mindset (Dweck, 2006) is the belief that intelligence, skill, and character are developed through effort, good strategies, and support from others — not inherited as fixed traits.
The opposite, fixed mindset, causes people to avoid challenges (to protect their "natural talent" image), give up quickly after setbacks, and interpret errors as evidence of inadequacy rather than learning signals.
The mechanism connecting growth mindset to metacognition: believing your mind is trainable makes metacognitive monitoring and regulation worth doing. If you think your intelligence is fixed, why bother analysing your errors?
Important caveat from Yeager et al. (2019): growth mindset interventions work only when students also have access to high-quality learning strategies. MindFrame is designed to provide both: the mindset framing and the specific metacognitive training protocols.
