I thought I would follow up yesterday’s post on ESRI technical certification and my GIS curriculum with a discussion of the UCGIS Geographic Information Science and Technology Body of Knowledge project. I don’t think that ESRI is in any way intending their certification program to be a model curriculum for the entire field of GIS, but it got me thinking about how their requirements fit in with the UCGIS Body of Knowledge (BoK).
First, a little about model GIS curricula. When I first started teaching GIS full-time back in 2001, I was so happy when I discovered the National Center for Geographic Information and Analysis (NCGIA) core curriculum in GIScience – first the 1990 version (still faithfully hosted by Brian Klinkenberg at UBC), and then the revised version. I was in the process of developing my teaching material for several courses, and really wanted to model my own curriculum after something authoritative, and what better than the NCGIA? Their core curriculum included actual lecture notes and figures (although the figures were sometimes omitted or hard to find). The list of contributing authors was impressive, and included some big names in the field: Mike Goodchild, Peter Dana, Albert Yeung, Jacek Malczewski, Kenneth Foote, David Unwin, and many others. I adapted some of this material for my own lectures but quickly realized I would have to refer to a wide variety of other sources in order to make sure I really knew what I was talking about, and had found the best way to explain a particular topic. Nonetheless, it was a great source for thinking about the organization of topics, as well as a great reference. Unfortunately, the last update to the core curriculum was August 13, 2000.
I’m not familiar with all the details, but my understanding is the core curriculum project was handed over to the UCGIS who agreed to carry it forward. The list of the UCGIS editors, contributors, and board members is truly impressive. They started on it in 1998 and the first version of the Body of Knowledge was published in 2006. I had been monitoring their progress before it was published, read the “straw man” version, and ordered a copy of the BoK as soon as it was finally published. I have to say that my initial reaction was one of disappointment. What was included was great – there was a well thought out list of topics and goals. What was missing was the actual substantial content I thought would be included, as was done with the NCGIA core curriculum. I realize that getting as far as they did was a huge feat, and I in no way want to detract from their accomplishment, but I had envisioned something more like the book Geographical Information Systems: Principles and Applications (known as the Big Book of GIS) by Maguire, Goodchild and Rhind, 1991, (which weighed in at over 1000 pages). However, I certainly still refer to the current BoK and look forward to the planned second edition.
This all brings me to what I wonder is the bigger question: is it even feasible to try and have a core curriculum? Has the field of GIS become so wide and varied, and does it change so quickly, that any attempt to capture it all in one curriculum is becoming unrealistic? It took 8 years to publish the first UCGIS Book of Knowledge – how much had changed during that time, and is this a constantly moving target? Or is there still indeed a “core” set of concepts that define the discipline? I would love to hear your thoughts, and will likely write more on this topic in the future.
