Project Description

Summary:  View help for Summary Vocabulary is critical to literacy development in early childhood, yet large disparities in vocabulary knowledge persist between children from high-income and low-income backgrounds. In a randomized evaluation, researchers evaluated the Big Word Club, a classroom-based digital learning program designed to increase the vocabulary of young children, to assess the program’s impact on children’s receptive vocabulary. Researchers found that the Big Word Club increased students’ knowledge and retention of words included in the program.
