If you don’t know about something, how would you know to seek PD in that area? This is especially true of learning with technology. I have a master’s degree in educational technology. The fact is that not any of the applications or computers that I learned on, as well as the methodology in the use of those components, exists today. Very little of that degree would be relevant, if I did not continue to learn, adapt and progress with what I know. The same holds true with any degree in any profession.
