Preschool for 4-year-olds

 An important effort that I hope works and is expanded:

Amid a political push for government-funded preschool for 4-year-olds, a growing number of experts fear that such programs actually start too late for the children most at risk. That is why Deisy Ixcuna-González, the 16-month-old daughter of Guatemalan immigrants, is wearing a tiny recorder that captures every word she hears and utters inside her family's cramped apartment one day a week.

Recent research shows that brain development is buoyed by continuous interaction with parents and caregivers from birth, and that even before age 2, the children of the wealthy know more words than do those of the poor. So the recorder acts as a tool for instructing Deisy's parents on how to turn even a visit to the kitchen into a language lesson. It is part of an ambitious campaign, known as Providence Talks, aimed at the city's poorest residents to reduce the knowledge gap long before school starts. It is among a number of such efforts being undertaken throughout the country.
