Thanks for the warm welcome, @James Kerman
Truth be told, I'm actively working on advanced degree number two.
Degree no.1: an MA in History (post-1865 American, though I studied and taught modern Europe too). I did the obligatory archival research & monograph writing, but my primary area of interest was how to teach history effectively so that students felt they were learning something of value, something relevant to their daily lives. (After all, the reason we teach the past is so we humans can look toward the future!) That got me interested in the science of learning, particularly the uses of storytelling, data visualisation, and interactive materials. I started corresponding with a few professors who specialize in those areas, which led to...
Degree no.2: Instructional Design (in progress)

I'm happy to nerd out about learning theory if anyone wants to know - otherwise I will spare you the deluge.
If nothing else, I'm sure folks on the KSP forum can agree that learning is fun. ;D
