“…This gap shows up earlier in education (Mullis et al, 2020), and grows later on through adolescence (INVALSI, 2019;OECD, 2019) up to adulthood (Borgonovi et al, 2018). However, the gender disparity is not consistent across countries (Else-Quest et al, 2010), with more egalitarian countries, with equal educational opportunities for women and men, displaying a smaller or nonexistent gender gap (Spelke, 2005;Guiso et al, 2008;Cook, 2018). Some recent research failed to find empirical support for gender differences in basic numerical skills and early mathematical cognition (e.g., number and dot comparison, dot estimation and arithmetic, Hutchison et al, 2018; numerosity perception, counting and elementary school-based math concepts, 1 Official website: https://www.oecd.org/pisa/ 2 Official website: https://www.oecd.org/skills/piaac/ Kersey et al, 2018), suggesting that female and male children and young students enter formal education with the same level of mathematical knowledge.…”
