Longitudinal Literacy Study

Dr. Stephen Krashen, international linguistics scholar, and his colleagues have completed the third phase of his longitudinal study of significant factors in children’s levels of literacy. Using the PIRLS test, he found that school libraries and their collections were the main contributing factor, and made up for some of the negative effort of poverty. Direct teaching and early literacy did not have a significant effect. Access the paper at Krashenpredictors of PIRLS
