John Hattie on Effect Size

This school year my literacy coach has been going on and on about the research of John Hattie.  Hattie has been studying the various things that have an impact on a students education.  In his research he ranks these things based on their effect size on a students education.  It is very eye opening to see the small things and how they impact students and the larger things that we sometimes think have more of an impact or less.  His research paints a picture of what students need and how students learn in various environments.
