From the report: "In this report, we explore another dimension of achievement growth differences during the pandemic that has received little attention: student gender. There is emerging evidence of differences in achievement growth for male and female students during the pandemic (Sass & Goldring, 2021), yet there has been little to no work to understand the causes of such gender differences and the implications for education policies. We focus on two potential mechanisms associated with the switch from in-person to remote learning: changes in the nature of peer interactions and differences in the level of self-control required to learn in a remote environment."
