Welcome to Educator in Residence. I am glad you decided to join us, and—if I might—I wanted to welcome you, and also take a moment to explain where all the light switches are. Allow me to change the metaphor. This is a Substack newsletter and, as is the custom on these DC-10 airplanes, some of you are in coach and some of you are in first class. The first class customers are the paid subscribers and have access to all the new content that I hope to be publishing here on the subject of education. These folks will have a newsletter appear in their in-box at least monthly, and sometimes, when the fit is upon me, it may be more often than that.
