In 2005, Mael et al. (see reference below) published a systematic review on the single-sex vs. coeducational schooling topic. They found a little advantage for single-sex schools. However, in 2014, Pahlke et al. contradicted their results through a meta-analysis. Also, Signorella et al. published a study specifically describing the weaknesses of the Mael et al. publication. Does someone know if the 2005 authors had answered any of them?
