Need for theory and model consolidation

"It is important that we examine the bases out of which a field of knowledge developed, the theories of the field that have operated with some success, and how current work can be consolidated into new models pointing the way to further development. That is what Dr. Reigeluth and his authors have attempted with respect to their field of instructional design."

"Can we really claim to have a base for solidly designing instruction? It seems only a short time ago that learning theorists were telling us that they did not think they had anything substantial to tell us about the practice of instruction. Of course, shortly after that, such modesty faded when behavioristic psychology was translated into teaching machines and into programmed learning. Education was to be revolutionized. But that has not happened. Though the tantalizing promise of these ideas remains, both teaching machines and programmed instruction have yet to achieve substatial educational roles. This suggests that there is much yet to be learned about instructional design. New and more fully developed formulations of theory into practice are needed."

"..the effort is made to move to a level where there is a sufficient translation of the abstract to make instructional design practical at some level."

"Proceeding from the abstract to the practical dominates the models presented, but going from practice to theory also has its advantages. It can give a grounded base that is close to reality."

"Claiming to set forth a general model of instructional design when leaders in the field like Cornbach (1975) are raising questions as to whether there are any significant principles of psychology that are not situationally specific may seem daring and presumptuous."

Learning Environment

The learning environment can be one or both of the following: 1) Content providing: e.g. other skiers provide good and bad examples, mountain provides visual input to understand skiing (compared to talking about skiiing in a classroom, chalkboard drawings, pictures, video, etc...) 2) Performance enabling: e.g. the mountain, snow, a ski lift, provide a place to ski; skis, boots and poles provide equipment to ski. e.g. a harness can help a diver safely learn a new dive, e.g. a foam pit can help a gymnast safely learn a new move

Preface note for dissertation

Although I feel that this work is of value it seems so insignificant compared to what I have learned in producing it. If only I could give that to the world, then I would feel my contribution is truly great. However, that progression is not something that can be given, but rather something that each person must discover and attain individually. Hopefully this work will, at least, give a good strong nudge in the right direction. (me, 2008)

Trait vs state

"A useful distinction in the discussion of student characteristics is trait versus state. Traits are student characteristics that are relatively constant over time...whereas states are student characteristics that tend to vary during individual learning experiences, such as level of content-specific knowledge." (Reigeluth, 1983, p. 32) Reigeluth also states that "many strategy components have been shown to help students with all kinds of traits to learn" [p. 32]. My position is that we do not know a priori which aspects of our instructional strategies, learning environment, motivator, etc... will generalize across many or all students. However, with a localized learning theory we can learn over time which do and which do not. At the same time, we will likely find ways of grouping students that we never would have before imagined.
