Avery Pickford. Three reasons.
- He’s a DFW-style expert, the kind of academic whose research is virally accessible to laypeople.
- He composes some relentlessly good rubrics for good math instruction.
- He commutes easily between the two warring math factions. I’m referring both to the evenhandedness of his most recent rubric and also to the grace with which he inserted himself into a debate at a recent math circle meeting concerning calculator use, the sort of debate that usually lures the blustering ideologues out of hiding but which saw the young Pickford articulating a lot of justice and respect between both sides.
