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.
