Trevor Bond is enlisting my help with some technicalities as he and Christine Fox work on the next edition of their excellent book "Applying the Rasch Model" (Erlbaum). "Applying the Rasch Model" is not bed-time reading. It needs active thought. As usual, it's some of the "simplest" things that are the most challenging. "The doer alone learneth," Friedrich Nietzsche (1844-1900). So, I'm learning a lot as Trevor works through his introductory material. "Learning is an active process. We learn by doing. Only knowledge that is used sticks in your mind." (Dale Carnegie)
