Art Rolnick gave a TED talk on why public and private investments should target the early education of disadvantaged children. His research is based on the analysis of a major research study (Perry Preschool Study) of the lifetime benefits of early intervention.
Art lays out what his research indicates is needed to prevent the achievement gap. Here's where he lays out the case and what needs to be done (it takes 2-3 minutes). 10BH hits all 3 of the 5 points he makes (see table below), with the other 2 points in process.
