I am amused b/c DH (mathematician) said the same thing about geometry and teaching of "math" this morning -- because I complained about an innumerate phone-in show host.
He made another comment I found interesting; he doesn't think there have ever been a sufficient number of qualified teachers of mathematical reasoning/logic to meet the needs of the next generation. He's going back the length of history with that, I think he considers it to be a fundamental problem of the species. It was strong wording, and philosophically interesting to this non-math brain
