Adding math talk to story time at home is a winning factor for children's math
achievement, according to a new research from a university. The study from psychologists
Sian Beilock and Susan Levine shows a marked increase in math achievement among
children whose families used Bedtime Math, an iPad app that delivers engaging math story
problems for parents and children to solve together.
Even children who used the app with their parents as little as once a week saw gains in
math achievement by the end of the school year. The app's effect was especially strong for
children whose parents tend to be anxious or uncomfortable with math.
Previous research from this group has demonstrated the importance of adults' attitudes
about math for children's math success. For example, a recent study found that
math-anxious parents who help their children with math homework actually weaken their
children's math achievement.
The new findings demonstrate that structured, positive interactions around math at
home can cut the link between parents' uneasiness about math and children's low math
achievement.
"Many people experience high levels of anxiety when they have to solve a math
problem, with a majority of adults feeling at least some worries about math," said Beilock,
professor in Psychology and author of Choke, a book about stress and performance. "These
math-anxious parents are probably less likely to talk about math at home, which affects
how competent their children are in math. Bedtime Math encourages a dialogue between
parents and kids about math, and offers a way to engage in high-quality math interactions in
a low-effort, high-impact way."
Study participants included 587 first-grade students and their parents. Families were
given an iPad installed with a version of the Bedtime Math app, with which parents and
their children read stories and answer questions involving math, including topics like
counting, shapes and problem-solving. A control group received a reading app that had
similar stories without the math content and questions related to reading comprehension
instead. Children's math achievement was assessed at the beginning and end of the school
year. Parents completed a questionnaire about their nervousness with math.
The more times parents and children in the math group used the app, the higher
children's achievement on a math assessment at the end of the school year. Indeed, children
who frequently used the math app with their parents outperformed similar students in the
reading group by almost three months in math achievement at year's end.
