“…In different African case studies, Lee and Lockheed (1990), Mbilizi (2010) and Picho and Stephens (2012; as cited in Evans, 2014) have reported the positive effect of single sex (girls) schools on the academic achievement of girls. Besides academic achievement, some researchers have pointed out the positive impact of single sex schools on speaking abilities (Ebrahimi & Yarahmadzehi, 2015), self-esteem (Sullivan, 2009), participation in physical activities and subject selection (Spielhofer, Benton, & Schagen, 2004), and co-educational settings have been considered as a risky environment for girls where girls are marginalised and belittled (Francis, 2000; Jackson, 2010; Jackson & Bisset, 2005; Pahlke, Bigler, & Patterson, 2014). In parallel, there have been studies which highlight the disadvantages associated with single-sex schools.…”
