Collaboration, or working in groups, is a favorite pedagogical strategy of hung-over graduate teaching assistants, soviet indoctrinators, educators with advanced degrees, and social studies teachers too dumb to do anything else.
Unfortunately, by what I saw at the National Council for the Social Studies (NCSS) conference here in Atlanta, most social studies teachers are either wicked indoctrinators or too dumb to know that they are carrying out the wishes of the Dr. Evils in education, i.e., those with Ed.D.s who are administrators, curriculum devisers, and education professors.
Teachers seem to love “group work.” It gives them a sense of power over children and allows them to catch up on Facebook or their nails...
While much has been said about politically correct material, little attention has been paid to such emotionally coercive teaching strategies. I saw how it is applied to middle school students as a teacher shared teaching tips for getting tykes to sympathize with illegal immigrants.
Read her full report on the conference at Indoctrination without Apology: Social Studies Teachers Share Strategies on How to Mold Students. It's pretty amazing.
