As more states consider universal preschool programs, a new study led by a Michigan State University scholar suggests that two years of pre-K is beneficial although more time should be spent on teaching certain skills.
In the current issue of the Early Childhood Research Quarterly, Lori Skibbe and colleagues argue that pre-K programs generally do a good job of teaching literacy and that two years of preschool is better than one.
However, the researchers also recommend that preschool teachers focus more on vocabulary instruction and exercises that build self-control as part of a broader curriculum.
"In terms of kindergarten preparation, I believe preschool does a very good job in certain areas in promoting children's skill sets," said Skibbe, MSU assistant professor of child development. "But it might do a better job if there was also explicit attention directed at building children's self-regulation and vocabulary skills."
The researchers assessed the skills of a cohort of Michigan children attending the first and second years of preschool (generally, 3- and 4-year-olds). The study was one of the first to directly assess self-regulation in this age group.
The findings come amidst a brewing controversy over preschool. Many states are debating whether to offer preschool to all families and how many years children should attend an important policy question in a time of tight budgets.
Some researchers argue that pre-K programs such as Head Start, a federally funded program for low-income families, offer no long-term benefits for children.
Skibbe disagrees. The study found that attending preschool was associated with gains in literacy skills specifically, learning the letters of the alphabet and comprehending how they go together to form words.
Skibbe said she supports a preschool curriculum that combines a focused, "holistic approach" to all three elements literacy, vocabulary and self-control.
"Children should be spending more time in preschool, not less, because the results appear to be cumulative," she said. "Children who spent two years in preschool, for example, did better in literacy."
