Our private school has recently gone off the constructivist deep end, driven by two administrators who have no children of their own and were educated in the 60's. Neither has been in the classroom for 25 years or more, but they love the educational theory! The classroom teachers, most of whom are young parents, are much more pragmatic in their approach. Interestingly, many of them have their own kids in more traditional schools.
This site uses left-brain and right-brainnot as physiological terms for the actual left and right hemispheres of the brain, but as they are employed in the everyday vernacular. They appear here in the same spirit in which people use type A and type B (themselves the relics of a debunked theory about blood type and character type): an informal shorthand for certain bundles of personality traits.
