New Research on Kids’ Poor Math Achievement
If the thought of a math test makes you break out in a cold sweat, Mom or Dad may be partly to blame, according to the new research published in Psychological Science.
A team of researchers found that children of math-anxious parents learned less math over the school year and were more likely to be math-anxious themselves—but only when these parents provided frequent help on the child’s math homework.
Previous research from this group has established that when teachers are anxious about math, their students learn less math during the school year. The current study is novel in that it establishes a link between parents’ and children’s math anxiety. These findings suggest that adults’ attitudes toward math can play an important role in children’s math achievement.
“We often don’t think about how important parents’ own attitudes are in determining their children’s academic achievement. But our work suggests that if a parent is walking around saying ‘Oh, I don’t like math’ or ‘this stuff makes me nervous,’ kids pick up on this messaging and it affects their success,” explained Beilock, professor in psychology.
“Math-anxious parents may be less effective in explaining math concepts to children, and may not respond well when children make a mistake or solve a problem in a novel way,” added Levine, Beilock’s colleague.
438 first- and second-grade students and their primary caregivers participated in the study. Children were assessed in math achievement and math anxiety at both the beginning and end of the school year. As a control, the team also assessed reading achievement, which they found was not related to parents’ math anxiety. Parents completed a questionnaire about their own nervousness and anxiety around math and how often they helped their children with math homework.
The researchers believe the link between parents’ math anxiety and children’s math performance stems more from math attitudes than genetics.
