There was an interesting article in the NY Times this morning under the SchoolBook column, 'Nonfiction Curriculum Enhanced Reading Skills, Study Says.'
Ten pilot schools were given reading curriculum which focused on nonfiction titles, and when tested after three years, their scores were higher than other schools. Some big names in education chimed in for this article.
E.D. Hirsch and Lucy Calkins were both quoted and the article is worth a read!
