After being in urban education for numerous years, educators are always trying to find out what works best. So often you look to how you were educated as a child and mimic how you learned information. We now know that yes that works but it doesn't work best!! When Hattie updated his meta-analysis studies it gave all educators who use the material a level playing field. If you inherited students who were behind on their studies you can apply an evidence-based strategy to reduce that deficiency. Thanks to Hattie for compiling these amazing studies.
