How you can be good at math, and other surprising facts about learning | Jo Boaler | TEDxStanford

Jo Boaler highlights the pervasive and dangerous myth that some people are inherently 'math people' and others are not. She contrasts this belief with other subjects where learning is understood to be acquired, not innate. This fixed mindset leads to widespread underachievement in mathematics, affecting students, teachers, and parents alike.

Research by Carol Dweck on mindset demonstrates that believing in one's unlimited potential leads to higher achievement. A study by Jason Moser using MRI scans shows that the brain actively grows when making mistakes in math, with more synapses firing. Crucially, individuals with a growth mindset show even greater brain growth when making errors, illustrating the link between cognition, beliefs, and feelings.

Boaler argues that traditional math classrooms with short, closed questions reinforce a fixed mindset. She proposes opening up math problems to create space for learning. She illustrates this with a visual square growth problem, demonstrating how different individuals perceive the growth in unique, creative ways, leading to deeper mathematical understanding beyond just counting or algebraic formulas.

A surprising fact from neuroscience reveals that when adults calculate, the brain area associated with seeing fingers lights up, even if they aren't using them. Finger perception is a strong predictor of calculation scores and math achievement in early grades, even more so than test scores. Despite this, students are often discouraged from using their fingers, which can hinder their numerical development.

Boaler describes a study where 81 students were taught with growth mindset principles, creative, and visual math methods over 18 lessons. These students, many of whom initially declared themselves 'not math people,' improved their standardized test scores by an average of 50%. The video includes a clip of students expressing their newfound confidence and enthusiasm for math through a song.

The speaker emphasizes the critical need to disseminate research on math teaching and learning to educators. She shares a middle school student's reflection on shifting from 'boxed-in' worksheet math to collaborative, open-ended approaches, highlighting the profound impact on their belief in their own potential. The core message is that focusing on students' beliefs about their potential is paramount to unlocking success in mathematics.
