Someone asked me at the recent Teaching Professor Conference how many articles on teaching and learning I may have read. I can’t imagine. We’ve be publishing the Teaching Professor newsletter for almost 20 years now, and for every issue I read a gaggle of pieces in my search to find the best ones to highlight. I have a four-drawer filing cabinet in my office into which I cannot cram another file—it’s a good thing many of the articles now exist in electronic formats. I have read a lot.
