This week on “The Learning Curve,” Cara and Gerard are joined by Meghan Cox Gurdon, the Wall Street Journal’s children’s book reviewer and author of The Enchanted Hour: The Miraculous Power of Reading Aloud in the Age of Distraction. Meghan shares what inspired her interest in becoming a children’s book critic, after having been a foreign correspondent. She discusses her ideas about the importance of spending time reading aloud, and the impact of the heavy use of technology on children’s literacy. She delves into the “Goldilocks effect,” a concept from cognitive science and developmental psychology mentioned in her book, and describes the brain research behind the value of reading aloud with young children. They also explore how reading aloud helps close the vocabulary and general-knowledge gap, especially among struggling students, as well as its importance for kids in the middle and high school years. Lastly, she shares her views on how to evaluate the quality of children’s books.
