For my graduate class this semester, there's a lot of paper-reading, and I view learning how to critically and constructively read papers as part of the student goals for the class.
A corollary of this, it seems to me, is that the class should include some bad papers, so students learn to recognize (and, if possible, get something out of) reading those. So I need some really good examples of bad papers. (In one of the areas of the class focus -- web search, compression. coding, streaming data structures...)
Now I should be clear about what I mean by bad papers. I'm looking for something of a higher standard than an automatic journal reject -- I get at least one of those a month in my mailbox, and it's not clear there's much to learn from that. I'm talking about papers that at least superficially look quite reasonable -- indeed, I'm expecting papers that have been published in reasonable places -- but when you think about them more, there are subtle (or not-so-subtle) flaws. In theoretical papers, possibly it might be that the paper starts with a model that sounds really nice but it just clearly wrong for the problem being addressed. For systems papers, it might be a paper where the experiments just don't match up to what ostensibly was being proposed.
[I had a nice example of a bad paper in earlier incarnations of the class, but I don't think it's aged well, and I've removed it.]
Maybe bad is even the wrong term for what I'm looking for. Perhaps I should use a more neutral word, like "controversial" -- indeed, then I can get the students to take sides. (Is the Faloutsos, Faloutsos, Faloutsos paper still considered controversial these days? That could be a nice example, but it's not really on topic for the class.) Or perhaps I just want papers that reached too high for their time -- noble failures. The key is that, in my mind, just showing students examples of great papers doesn't seem didactically sound. Negative examples are important for learning too (especially if they also show that great scientists don't always get it right).
Feel free to mail me rather than post a comment if you're afraid of offending anyone. Naturally, mailing me links to my own papers will be taken with the appropriate humor.
