Ironically, the author of the petition is a physician with far more (public) education than the OP.
The 'discovery learning' program has been a flop in Alberta since it began a decade ago to much opposition.
A decade ago, as measured by independent international rating body PISA, Alberta students overall were easily at the top of student achievement testing in Canada and near the top internationally.
Not anymore, and the prime reason is the program Comrade Socialist touts all the time.
Luckily, teachers are sabotaging the program from within, school boards are backing off, and Alberta Education is crumbling under the assault by angry parents.
This crap won';t be around much longer.
