What if the single greatest predictor of a student's success isn't intelligence or resources, but a spark that can be systematically ignited? A wealth of compelling data reveals how intrinsic motivation, not extrinsic rewards, drives profound engagement and achievement, with a landmark study showing that students' own internal drive accounts for 42% of their long-term academic engagement, while targeted strategies from autonomy-supportive teaching to purpose-driven curricula can dramatically amplify this powerful force.
Key Takeaways
