Julio teaches middle schoolers the way he teaches his AP research students: find the source, weigh it, build the argument, defend it out loud. Ten years in a large American public high school taught him how to pitch that work at twelve without thinning it. The three words he took from the school where he started still describe the job for him: educate, affirm, inspire. A child in his room learns to disagree with a text, with evidence and with courtesy.
