When I took my AI class, my professor would assign one paper a week and we had to turn in a "critique" of that paper. These papers were, of course, the seminal classics in the field, because what else would you want your intro class to be reading? I complained a bit to the professor that it was a bit silly to critique the seminal papers in the field and if you want to be sure we read it, we could just turn in a summa…
In my freshman Composition class we needed to pick a controversial topic and argue one side. Highest grade on that assignment went to someone who argued that smoking causes lung cancer (this was 2003). The instructor explained that it was the most convincing paper. Those who picked an actually controversial topics got the lowest grades because their arguments were less of a slam-dunk.
