Why words count

Children who enter kindergarten with a small vocabulary don't get taught enough words—particularly, sophisticated academic words—to close the gap, according to the latest in a series of studies by Michigan early-learning experts.

The findings suggest many districts could be at a disadvantage in meeting the increased requirements for vocabulary learning from the Common Core State Standards, said study co-author Susan B. Neuman, a professor in educational studies specializing in early-literacy development at the University of Michigan in Ann Arbor.

"Vocabulary is the tip of the iceberg: Words reflect concepts and content that students need to know," Ms. Neuman said. "This whole common core will fall on its face if kids are not getting the kind of instruction it will require." (Sarah D. Sparks at Education Week)
