METHODThisstudyisnotarandomizedcontroltrialstudy(i.e.,studentswerenotrandomlyassignedtoconditions).Becauseofmanythreatstointernalvalidityunderthisdesign,thisstudydoesnotattempttomakecausalclaimsontheimpactofFreckleinstudentscores.Rather,itexploreswhethertheresultsareconsistentwiththehypothesizedpredictionsrelatedtotheimpactofFreckleonstudentachievement.
