Hear all about the Saul Zaentz Early Education Initiative at the Harvard Graduate School of Education. The initiative (one of the largest funding of early childhood education initiatives in history) focuses on the knowledge, professional learning and collective action necessary to cultivate optimal early learning environments and experiences. They’ve recently launched a first-of-its-kind study on examining the environments where 3- and 4-year-olds learn best. Yet little is known about the children who are looked after under informal arrangements involving neighbors, relatives, friends, or nannies, even though these cover 40 percent of children in Massachusetts. Harvard Graduate School of Education (HGSE) professors Nonie Lesaux and Stephanie Jones, both developmental psychologists, are launching an ambitious study to follow 5,000 children, ages 3 and 4, for four years. The study will track some students before and after their elementary school years, and perhaps into adulthood. The cohort, recruited from 168 communities, is designed to reflect the changing demographics of children across the state. "We want to understand and unpack the insides of child care environments - not just large centers - homes and elsewhere".
