Harness potential of low-income students by valuing what they already know

“A popular theory of social science says that children of highly educated, professional parents hear about 30 million more words by age 4 than do the children of low-income parents with less formal education.

Children enter school with very different levels of language ability, which affects everything from their placement in classroom learning groups to their performance on standardized tests and, eventually, their ability to access college or white-collar jobs.”
