Education changes lives in ways that go far beyond economic gains. The data show clearly that children who get better schooling are healthier and happier adults, more civically engaged and less likely to commit crimes. Schools not only teach students academic skills but also noncognitive skills, like grit and teamwork, which are increasingly important for generating social mobility. Even the friendships that students form at school can be life-altering forces for social mobility, because children who grow up in more socially connected communities are much more likely to rise up out of poverty.Conversely, limited social mobility hurts not just these children but all of society. We are leaving a vast amount of untapped talent on the table by investing unequally in our children, and it’s at all of our expense.Researchers have also used big data to uncover many specific education reforms that could lead to huge improvements. For instance, the evidence is clear that teachers are critical; my co-authors and I found that, when better teachers arrive at a school, the students in their classrooms earn around $50,000 more over each of their lifetimes. This adds up to $1.25 million for a class of 25 in just a single year of teaching.Smaller classes and increased tutoring also lead to long-term gains for students. Charter schools have revealed a range of effective approaches as well, often to the benefit of some of society’s most disadvantaged children. Children also benefit from longer school days, greater access to special education and less aggressive cutoffs for holding students back a grade.
This sentence expands the value of education beyond academics, emphasizing that schools shape character and social behavior. It supports the idea that education has broad, lasting impacts on a child’s future, especially for those trying to overcome poverty.
