I've taught at schools so short-staffed that their own full-time teachers were the first ones turned to in order to fill in for teachers who couldn't show up. Perhaps this is for the best, as it has given me a glimpse of just how mind-numbingly tedious substitute teaching can be, at least compared to having an audience for a portion of the class when teaching your own teachables. I would never have believed the difference was so stark if I hadn't seen it with my own eyes. Most of the time, it consisted of just supervising students while they catch up on bookwork or projects. There has to be something more involved a substitute teacher; especially one from the same school; can do than just that. Hopefully, something more beneficial to students and staff alike. Often times, teachables are based on your major and your minor. But one often has electives in addition to your major or minor. Why can't these electives be accepted as the basis for getting to teach a more involved lesson on the subjects to which a substitute is assigned? University credits aside, high school transcripts can reveal an outstanding grade in the same course they proceed to teach, and brief assessments of a substitute teacher can confirm whether or not they retain an adequate portion of it after all these years. Course credits aside, many schools have "pre-tests" on a given course, for which if a student demonstrates prior knowledge of the content well enough, they are excused from ordinary classes to get a head start on future courses' content with the other more knowledgeable kids. Why can't we have similar pre-tests for substitute teachers, to see if that podcast they like to listen to is truthful enough; and retained well enough; to allow one to teach a subject that podcast is about? Academic criteria aside, what of other jobs substitutes have? Substitutes range from full-time teachers to full-time substitutes, but in the middle are people who substitute part-time and have jobs other than teaching part-time. Wouldn't the perspective of a substitute teaching something they learned on the job, rather than from other academics, be a little more refreshing?
