sort of a tangent, but I wonder if the emphasis on proper scholarly citations gets in the way of the actual critical thinking part. when I was in middle/high school, most of the teachers seemed to care more about us following the APA/MLA format perfectly and using proper "authoritative" sources than whether our arguments actually made sense. I was never very efficient at making bibliographies or sifting through academic papers, so I felt a perverse incentive to cite as few sources as possible.
the one exception was my teacher for a public policy elective. he considered any reasonable newspaper to be an acceptable source, and accepted a simple footnote with a link as a citation. the catch was that he would actually follow the links and dock points if we had misinterpreted the source or failed to address the source's bias. I recall that students actually wrote some good papers in that class...
