I’m also thinking about what these interviews said collectively about how real research is conducted. It makes me a little crazy when students abandon a truly interesting question because they can’t find sources to quote that provide the answer, or when they change their topic based on what they can find easily. Or (shudder) when they say they've written their paper, but need help finding five sources to cite. Clearly, they are not learning how to do research; they aren't even learning what research is.
What I would really, really like is to figure out how to give every student the experience of not worrying so much about getting the right answers, but learning how to ask a really good question. The kind they won't find answered in the library.
