if it’s hard, we’ll add the visuals

Watching the pretty awesome algebra2go video on conversions.   Here is my conundrum.   Okay, first that he goes rolling all the way through multi-step and multi-dimensional conversions in the same fell swoop, though that has its advantages, and  if I’m a teacher I can break it up — and a student could, too.   […]

ALEKS acquired

Seems McGraw Hill acquired ALEKS last June (and separated their “financial” part of the corporation from the educational). Pondering. When a company has financial products and educational products, is it much of a leap to suggest that educational materials are commodities to be produced, marketed and sold as efficiently as possible (as opposed to as […]
