So I'm sitting here look at this nicely done list of instructional design models; and I'm thinking this is why I am so wary of people or models promoting the "7" this or "9" that...I saw this panel at ISPI several years ago. It was supposed to be one of those "Myths, Fads, and Fallacies" of learning that are so much fun (so much fun in fact, we did a session of #lrnchat on it).
One of the "gurus" on stage was Thiagi. Brilliant and humorous as ever; Thiagi looked up and down the table and said, in that accent, "It's clear to me that I am the only Indian at a table full of chiefs." The crowd cracked up, but then Thiagi proceeded to tell the audience that the idea of "systems" thinking about something as inherently messy as learning was (and I'm paraphrasing) a bit arrogant. He did this with great style and humor and the whole room was chuckling the whole time.
The whole time though, I was looking around thinking "do you people hear what he is saying?" I think some of them didn't but some of them probably did and were laughing nervously. So when I look at this list and I think of Thiagi's talk, I'm reminded that what we may want to pursue is something more like a school of thought - with rooms for many models and many ways of thinking - but with an emphasis on the discipline, critical thinking skills, willingness to challenge accepted wisdom and intellectual curiosity and rigor that would serve all of us well.
