I put this assignment off for a long time, because I hate making graphics. Other teachers (like my wife) tell me to try this or that website or app, because they make the graphic easier or prettier, and I am always frustrated and disappointed with my product. When I got the inspiration for the graphic I made, I did it without going back to the assignment first, so I forgot to look for and try new tools, and I chose to use something familiar.
Normally for projects like this I use Apple Pages, but because this assignment will be part of a larger project that I am building in Google Sites, I chose to create my graphic in Google Drawings. Google apps are familiar to me, and they are generally easy to use, although they tend to have comparatively very basic functionality. I knew that this would likely save me some trouble in the short term, even if it caused some frustration; but it would save me even more trouble in the long term, because Google apps will play well together. I ended up exporting my graphic as a jpg file for easy portability, but I could just as easily publish and embed it in the final product.
As a learning experience, this was not particularly valuable to me. I discovered that my vision for the graphic was possible with a very simple drawing tool. I discovered that I could put something like this together with very little effort, and I may begin doing that more often. But this was not an exercise in exploration. As a lesson about learning activities with minimal instruction, I see that I default to what is familiar or minimally novel when given minimal guidance. If I want students to learn a new skill, I need to accompany them, or else they will meet my requirements with the least risk and the least learning.
