Looking at the constructivism and other articles where Dlewis3 has been flooding content with arguments from Kirschner, Sweller, and Clark. This author feels that since David Lewis has made these changes that Wikipedia isn’t the “nonbiased” source it claims to be. I think the author misunderstands Wikipedia’s NPOV though; controversial claims can be made if they’re cited, but so can arguments on the other side. NPOV doesn’t mean everyone agrees on a middle point. It means there is a balance with multiple positions explained. The point is to present the arguments, with citations, and let the facts speak for themselves.
