If as an educator and the read to inform yourself about your profession, I would propose you consider several books that are about the context within which educators function. Glass, for example, proposes that politics and economics are stronger determinants of learner experience than learning science. Educators may not think on this level, but to be effective advocates perhaps they should. All books here are available for the Kindle or Kindle app.
