If you choose to enroll at Walden because it is an online college that offers self paced course work for educators, you may start your education right away. Canter provides a study guide, but it is up to you to translate this guide into a workable schedule for you. Moreover, it is highly desirable that you follow the lessons in sequence rather than jumping around. Collaboration, which usually would be handled via the online in-class discussion board option, may now be conducted with a fellow teacher. Walden will grade class assignments, which you may turn in at your pace. As it stands, the materials you receive greatly mimic those of a correspondence course.
This kind of study is ideal for the highly motivated self starter who needs little outside push or validation to start and keep going. Unless you are passionate about teaching, eager for learning new models and concepts -- and willing to steadily fit in studying time -- this is not a good solution for you. Moreover, if you are a bit of a procrastinator or believe that you might at some point during your course of study suffer from the age old temptation to switch majors or change careers, it is best to stick with a predictable curriculum that the average distance education facility offers.
