I was thinking: When we require students — as we do here in WR 121 — to write a paper which integrates two textual sources and one personal source, isn’t that actually a more difficult assignment than had we required them to integrate three textual sources? In other words, doesn’t adding personal experience/knowledge to the mix require the student to do a better job of organizing, focusing, and cohering? Hasn’t it got to be harder to integrate two different types of sources than only one type — the more diverse the sources the more skill require to integrate them into one rhetorical act? Or maybe not? Or does it depend more on the sources themselves and the aim of the essay? Anyway, just a thought.
