In order for teachers to provide optimal instruction to their students, they must constantly stay abreast of changes in pedagogic theories, curriculum development, and regulatory issues. Not to mention that some subjects (like history, science, and math) must embrace new advances, discoveries, or shifts. Quite naturally, teachers who want to continue providing their students with excellent instruction must go back to school occasionally to become recertified are retrained. But given the hectic schedules that most teachers follow, this can prove quite difficult. Fortunately, there are programs that offer intermittent courses throughout the year (especially during summers and school holidays) that are designed specifically for instructors. By taking a teacher education course, you can brush up on new advances without sacrificing a lot of time.

Different courses will teach you different things. What you'll learn will really depend on what subjects you teach, the age groups you instruct, your school district, what advances have taken place since your last teacher education course, and so forth. But the ultimate goal of such courses is pretty much the same across the board. They are designed to help fill in the gaps and render you a more up-to-date and competent instructor. If you have been teaching for a while, it's quite possible that the "hard and fast rules" that you learned during your training a long time ago are no longer sufficient these days. By taking a teacher education course, you can render yourself a much more attractive educator, and equally important, your students will benefit from more relevant coursework and instructional practices.
