Charles Reigeluth developed Elaboration Theory, which focuses on improving retention and transfer of knowledge through sequencing content from simple to complex and concrete to abstract. The theory incorporates principles of cognitivism and behaviorism. Reigeluth's Elaboration Theory includes seven instructional treatments: elaboration, sequence, synthesizer, summarization, analogy, cognitive strategy activator, and learner control.

2. Charles Reigeluth
• Reigeluth is an educational
theorist who focuses on
instructional design
theories.
• He is a professor at the
Instructional Systems
Technology Department at
Indiana University.

3. Reigeluth’s Elaboration Theory
• This Theory includes Principles of
COGNITIVISM and to a lesser
extent those of BEHAVIOURISM
as well.
• Chief Aim of the Theory –To
develop better retention and
transfer and increase learner
motivation.

4. Seven Treatments of Elaboration Theory
Elaboration
Sequence
Synthesizer
Summarization
Analogy
Cognitive Strategy Activator
Learner Control

5. Elaboration
• Simple to the
Complex
• From the Concrete
to the Abstract

6. Sequence
• This sequence is one in which the
Shape of
the Earth
general ideas epitomize rather than
summarize, and the epitomizing is Rotation of
the Earth
organized on the basis of a single
type of content i.e. Revolution
Conceptual, Procedural, Theoretic of the Earth
al.
• It is necessary to determine if
learners have essential knowledge
that will allow them to learn the
specific content.

7. Summarization
• Summarization is the fourth
treatment in which the content
covered is reviewed and discussed
again.
• There are two types of summarizer –
Internal (summary comes at the end
of the lesson) and Within – set (This
deals with all that has been learned
so far in a particular set of lessons.
This can include other related lessons
)

8. Analogy
• It is an familiar idea or
concept to define a new
idea or concept.

9. Cognitive Strategy Activator
• In this treatment the learner
is presented with a situation
in which cognitive skills and
processes are put into
practice.

10. Learner Control
• It includes decision on how
much control to give to the
learner.
