The actual book of his that I have is "A Guide to Introductory Physics Teaching" - the book above is a later, expanded, version. has it listed for as little as < $25 used. (No preview is available.)

Yes, imagine how much richer physics would be if more people hadn't been turned off in the earliest classes, and if more teachers had taught things clearly. Of course, one could say the same thing about Economics, also too. :-D
