One way people learn new words is through reading books and stories. Little kids love hearing their favorite stories over and over and are also very good at learning new words. We wondered if reading the same stories could be helping preschool kids learn new words. Our research tested if it was better to read the same stories over and over or to read a few different stories. Here, we tell you about three studies that show preschool kids learn more words from reading the same stories over and over. Our research suggests that it is easier to learn new words from stories when you have heard the story before and know what is going to happen.
