What is Ed Tech...really

So I am obtaining my master's degree and the first assignment for this semester was to create a graphic organizer about educational technology. We were to simply demonstrate what we felt is encompasses in educational technology, what it draws from, and where it feeds in to. Several of my classmates had some wonderful graphics and representations, but mine is below. It really was such a simple task, but really got me thinking: What is it that I do? Where does it come from and where is it going? What does my job encompasss, and what will it encompass in the future? This was supposed to be the "easy first assignment," but I found it to be the most difficult. (Click the image to see a larger view.)
