“…In Stoet and Geary's (2015) work, they analyzed academic achievement data from four PISA assessments, representing 1.5 million learners, and found that girls outperformed boys in math, reading, and science. Most scholars (e.g., Adamuti-Trache et al, 2013;Etim et al, 2016;Legewie & DiPrete, 2012;Lörz et al, 2011) consider this as a significant change from the past that saw the prominence of the male advantage and, at the same time, a different version of disparity in the access to education. Such is still a problem that invites further research, since this gap will eventually have large-scale impact in various social, political, and economic structures (Berggren, 2011;Klasen & Lamanna, 2009;Seguino, 2000).…”
