New Study Backs Academic Rigor for Preschoolers. Oh, Please; from the Washington Post : A new study finds that preschool classrooms — those in which teachers provide “high doses” of activities “emphasizing language, preliteracy and math concepts” — give “positive” academic benefits to children as measured by standardized tests, and that black students generally get a bigger boost than others. Think flashcards. Nancy Carlsson-Paige, an early-childhood-development expert, recently wrote: We have decades of research in child development and neuroscience that tell us that young children learn actively — they have to move, use their senses, get their hands on things, interact with other kids and teachers, create, invent. But in this twisted time, young children starting public pre-K at the age of 4 are expected to learn through “rigorous instruction.” And never in my wildest dreams could I have imagined that we would have to defend children’s right to play.
