Boys and girls first come to school with comparable maths ability but a gender gap appears during their first year, according to French research. The team studied maths performance for over 2.5 million children aged 5-7 in France. They say while there was no difference in average maths performance between boys and girls when they started school, when the children were tested again after four months, boys were on average outperforming girls and this gap widened by the time they started second grade. The researchers say this shows whatever is causing a gap in maths performance between genders is likely happening in early school, and his needs to be addressed.

Social sciences: Early childhood gender gap in mathematics performance

A maths-performance gender gap in favour of boys is apparent after four months of schooling, according to an analysis of nearly three million first and second grade students in France. The findings are published in a paper in Nature.

Previous research has illustrated a gap between male and female children in mathematical performance beginning in early education, as observed in American and French cohorts. Although these studies have sought to understand why this gap emerges, whether it be the attitude of parents and teachers (such as gender stereotypes) or maths anxiety (which is more common in girls), these results are dated.

Pauline Martinot and colleagues analysed data from 2,653,082 first and second grade children (aged 5 to 7 years old) in France from a national evaluation program administered from 2018 to 2022. The researchers found that there was virtually no difference in average maths performance between male and female students upon the beginning of school, but after only four months, a notable gap between the two genders appeared, in favour of boys. This gap had quadrupled in size at the beginning of 2nd grade. Martinot and colleagues found that the variation in student scores was observed across the entirety of France and was independent of socioeconomic status, the type of maths test administered, and whether the school was public or private.

The authors note that a key limitation of their study is that they only observed data taken at three points in time: the beginning of the school year, four months later, and one year later. As such, granular details cannot be obtained on how the maths gender gap changes with time, which limits the possibility to generate specific mechanisms that cause the gap. Martinot and colleagues suggest that policymakers should consider addressing this gap as early in a student’s education as possible, such as kindergarten

Professor Jodie Hunter, Institute of Education, Massey University, comments:

This study supports what earlier research has shown about something called ‘brilliance bias’, the idea that doing well in subjects like mathematics, physics and other sciences is about having natural talent or being innately brilliant. What is interesting is that younger children often believe their own gender or group is the smartest at these subjects, but as they get older and move through schooling this begins to change. They begin to associate success in mathematics and science subjects with certain groups, unfortunately, those groups often don’t include girls or students from marginalised communities.

"This research is highly relevant for us here in Aotearoa and across the Pacific given that we see ongoing disparities in achievement, particularly for Māori and Pacific students. Research suggests that part of the problem is a lack of recognition for the strengths and knowledge that these students being into the classroom. It would be beneficial to see further research that looks at how we can support teachers and students to see everyone as capable of doing mathematics.
