But evidence is weak that there is such a thing as “girls’ learning,” online or offline, if what is meant by that is that each gender has cognitive differences that should be accommodated by different instructional methods. Neuroscientist Lise Eliot has argued persuasively that, while small inherent differences in aptitude between males and females do exist (even as infants, for example, boys seem to have an edge in spatial cognition), society takes these small differences and makes them much bigger—by supporting boys in math and science, and by discouraging girls who study these subjects.
