The "skimming" trap

I am guilty of an offense that I get on my students about: skimming. Yes, it's true. While I was reading the syllabus online, I did not see where it told us what we were supposed to be blogging about. I decided that the first must be your standard introduction and the topics for the rest would be discussed in class or posted in "Resources" in OnCourse, so imagine my surprise when in class I discovered that my second blog was due a few hours earlier. "But I couldn't find what we are supposed to write about!" I lamented to my classmates. Rusty pointed out to me exactly where it was in the syllabus. A document that I would have sworn I had read more than once. I then realized that I had fallen into the trap of online reading: skimming. I see a lot of people who have become so accustomed to the quick answer that we do not read "deeply," especially when the text appears on a computer screen. If the answer to our question is not in the first couple of paragraphs, we just zone out for the rest of our reading. This illustrates why even though it is old-fashioned I will often give short research assignments where students are not allowed to use the printer or cut and paste. They must (gasp!) take notes by hand. It is one way I try to get them in the habit of actually reading what they are reading. Plus, I want to break them of the habit of printing sixty page articles when they only need something in the first page. Any other suggestions to break the skimming habit?
