Hiatus
I had completely forgotten that I even had a blog. Tell me, are blogs still in vogue these days? Probably not. There are so many. But like they were out of a time capsule, here are my words in 2015. I read them, and they still make sense to me. Since I put these words on line I have added a good others to them and published them in a book. 2014.
This is 2015. So what's new? I think I have some speculative things I want to say. Since no one reads this anyway, what harm can it do? I would like to do some speculating: kind of an intellectual diary.
The first thing I would say is that I think instructional designers have it all wrong. Yes, that's right...wrong. I've been doing it myself for decades. We have intellectualized something that isn't intellectual. It's fundamentally emotional.
There are a lot of indications for this, and it may take me a while to get my thoughts into words. I think that the first things we teach new designers to pay attention to are not the first things a designer ought to pay attention to.
Learning is based first in emotion and tacit processes, but we teach instruction as if it were completely rational. I am convinced that what we refer to as knowledge is really more like a belief. I feel that instructing should be approached as if it was an appeal to the mind and the heart. I do not feel that we can rely on the design principles and processes of the past to lead us to the promised land of learning.
These are things I would like to talk about, and since I am in kind of an echo chamber here, I can write without fear of being discovered.

Why All the Noise About Functional Design?
- It's closer to what designers really do anyway
- It makes it possible to link theory in a more direct way to a design
- It allows the designer to tailor the process to the needs of the project
- It supplies an alternative to the traditional approach
- It corrects some of the shortcomings of the traditional approach
Functional Design and ADDIE/ISD
Functional design and ADDIE/ISD inform each other and are capable of working in a complementary way. Probably the two themes most important in describing the relationship are sequentiality and granularity.
Functional design orders design decisions according to project-specific patterns in response to constraints imposed by the problem’s context. ADDIE/ISD models represent an idealized case in which it is seldom made clear how prior constraints impact the idealized model’s processes. Functional design assumes the existence of prior constraints for every design problem that force the designer to re-assess the order of decision-making. Design order in functional design is determined by the “next most critical” rule for selecting decisions to be made, assuming that certain decisions have been made or are strongly indicated even before the project is launched, creating the “seed” from which the design expands outward in increasing detail.
Granularity refers to the degree of guidance provided to designers by a design approach. Functional design and ADDIE/ISD probably differ to the greatest degree with respect to granularity. This is because functional design operates within the same context as ADDIE/ISD, overlapping to some extent some of the ADDIE/ISD processes. However, functional design deals with the concerns of design within this context at a much smaller granularity and therefore scaffolds design efforts to a much higher degree during the critical phase where the design itself is being formed.
Functional Design V
Functional Design IV
Since it can’t be predicted what constraints will come with the problem, and since different decisions challenge different parts of a process model, functional design does not specify a design order. Instead, it follows next critical decision order. Gibbons (2009) defined several factors that may individually or jointly determine the next critical decision for a given project and moment within the design process:
- The decision most constrained by the latest previous decision.
- The decision most constrained by external factors, such as skill availability, infrastructure, resources, etc.
- The decision that best advances the central discipline of the primary generator.
- The decision that best takes advantage of an opportunity afforded by the latest previous decision.
- The decision that creates the most options for later decisions.
- The decision for which there is the most supporting data from the analyses of the target population and of the instructional context.
- The decision that represents the next highest quality priority.
- The decision that most directly addresses a major client criterion or desired feature.
- The decision that best leads to the satisfaction of an innovation goal.
- The decision that is most necessary to the implementation of a chosen theoretical position.
- The decision that responds to the latest prior decisions in other layers of the design.
Functional Design III
As decisions are made, either in singles, in clusters, or in order to serve an operational principle, each new decision imposes new constraints on future decisions, redefining again the options left in the problem solving space, making certain future decisions imperative, and shifting priorities for the next decision. This cycle of progressive placement of constraints continues until the minutest decision has been made firm. Functional design is a natural companion of design layer theory. Initial constraints on a design problem affect different layers. One project may require a particular medium to be used; another may require a particular social setting. Constraints influence the options available within different layers of the design. Moreover, constraints on one layer ripple effects to other layers, constraining decisions within them.
Functional Design II
- the representation function (provide sensory experience for the learner)
- the control function (give the learner a way to respond to the sensory experience)
- the message function (construct the individual messages of the instructional conversation--the ones that are to be represented)
- the strategy function (determine high-level strategic moves that support learning and drive messaging)
- the content function (supply content in appropriate form to the strategic, messaging and representation functions)
- media-logic (execute all functions)
- the data management (record data from the instructional encounter).
