His answer is that what American textbooks have carried for seventy years does not deserve the name \u2014 it defines almost nothing, explains almost nothing, and rarely says why any of it matters. Three reforms tried to replace it and fell short, he argues, because nobody had written down the alternative in enough detail for a teacher to use. So he spent twenty years writing it: six volumes, 2,402 pages, K through 12. The five principles he says any replacement must satisfy fit on a single page.<\/p>\n<p>Our overview, with a link to the full talk: [<a href=\"https:\/\/sedso.io\/reports\/us\/ca\/wu-on-math\/\">link<\/a>]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In March, Berkeley\u2019s Hung-Hsi Wu asked the European Mathematical Society a question that sounds too simple to need an hour: what is the mathematics we teach in school?
