Reigeluth's elaboration theory is a cognitivist learning theory that proposes instruction should be organized for optimal learning in tiers of. Summary: Elaboration theory is an instructional design theory that argues that content to be learned should be organized from simple to complex order, while providing a meaningful context in which subsequent ideas can be integrated. Elaboration Theory (Charlie Reigeluth) According to elaboration theory, instruction should be organized in increasing order of complexity for optimal learning. A key idea of elaboration theory is that the learner needs to develop a meaningful context into which subsequent ideas and skills can be assimilated.

Instructional content should be organized in order of increasing complexity Sequencing should reigeluths elaboration theory a holistic approach to foster meaning-making and motivation; whole-tasks are broken down reigeluths elaboration theory manageable part-tasks components Examples and elaborations should be embedded within activities and lessons Reigeluth uses the analogy of a zoom lens to explain the nature of elaboration Learners begin with a wide angle view to reigeluths elaboration theory the whole picture and major relationships within it e.
Learners need to develop meaningful contexts into which ideas and skills can be assimilated: Teach broader, more inclusive concepts, principles, or tasks before the narrower, more detailed ones that elaborate upon them.
This layering has a zoom lens sequencing approach that runs from simple to complex and repeated general-to-specific Reigeluth, Present overview of simplest and most fundamental ideas Add complexity to one aspect Review the overview and show relationships to the details Provide additional elaboration of details Provide additional summary and synthesis This zoom lens approach first looks at the subject through a wide-angle lens.
Elaboration Theory (Charlie Reigeluth) -
That is, the reigeluths elaboration theory matter is general and fundamental. This allows us to deal with the core aspects of the subject. Elaboration begins with an overview of the simplest and most fundamental ideas of the subject. Then we start to zoom in with the lens so that we pick up some details and specifics about the subject matter.
We reigeluths elaboration theory also observe the relationships between the wide-angle subject shot and the zoom details. This principle as applied to elaboration theory is called a cognitive zoom.
Elaboration Theory (Charlie Reigeluth)
As we reigeluths elaboration theory to zoom, we go into great detail with each iteration or layering. Note that we are primarily concerned with the sequencing of ideas as opposed to the individual ideas themselves.
Each zoom that we make is called a sequence. Base organization and sequencing decisions on learners' understandings as well as the logic of the subject matter Assume a more constructivist stance toward content structure and sequencing strategy A New Approach: SCM Simplifying Conditions Method Reigeluth proposed reigeluths elaboration theory specific method to provide practical guidelines to make a very different kind of simple-to-complex sequence reigeluths elaboration theory the hierarchical sequence.
It is more holistic approach than the hierarchical task analysis. How to design an SCM sequence?
Prepare for analysis and design: Two fundamental types of sequencing strategies in elaboration theory Topical Sequencing: Wilson and Cole make four recommendations for restructuring Reigeluth's elaboration theory: In its current form, explicit steps are provided for designing and sequencing instruction.
Elaboration theory should be reigeluths elaboration theory into a set of guiding principles referenced more clearly to learning processes.
A principle-based formulation will allow practicing designers to adapt the concepts to a greater variety of instructional situations. Remove unnecessary reigeluths elaboration theory constraints: ET may constrain designers without any demonstrable return in instructional effectiveness.
