I remember those back in middle school. My history teacher beat on us relentlessly to do them, to the point of having large stacks of paper with lines down the middle in the room and handing out bundles of the same at regular intervals. No one did it unless she was checking for a grade, which was infrequent. I did well in the class, and neither I nor the other A students took notes this way. Just sometimes wrote in the margins like normal people, or underlined something important, then put these into separate documents. Having a sheet of the synthesized "metadata" (dates, contextual bits, etc.) was much more useful than having to page through to get at the information.
