One of my Twitter people asked me to share my thoughts on yesterday’s Chronicle article, “Can Universities Use Data to Fix What Ails the Lecture?” At the time, I skimmed the article and replied thatLectureTools, the technological tool developed by Perry Samson to gather real-time data from students during a lecture, reminded me of the contraption you see in the photo to your left. That’s anautomated chalkboard eraser. As technology goes, it’s quite effective in what it does. Just look at how clean that board is! Which is great but… that’s a chalkboard for goodness’ sake. A piece of communications technology that is not significantly different than prehistoric cave drawing, and which has been improved upon countless times. (Purists who still cling to chalkboards: You guys are Luddites. Sorry.) Strapping an awesome piece of technology to a chalkboard doesn’t make the chalkboard suddenly better.
