2. Mobiles
A mobile is, in essence, a three dimensional
wallchart in which the individual components can move
about.
display, which turns and changes shape as it is
affected by random air currents, acquires a vitality which
can never be produced in a flat display of the same
material.
can be suspended in a corner of any learning room,
where they will not get in people’s way, but will still be
clearly visible.

4. How to create a Mobile
Conceptual Design.
This involves choosing the basic theme for the
mobile, deciding what items to include, and establishing
the patterns that you want to illustrate.
Production of Components.
Involves designing and producing the individual
components, which may be simple word cards, cut-out
models, plastic rods, symbols or even items of realia.
5. Assembling and mounting.
The most difficult part, and is best done by first
assembling the simplest groups of items, then
combinations of such groups, and so on until a balanced,
freely-moving display is achieved.
The final display should be hung from a hook or
drawing pin firmly fixed into the ceiling, or from a
wooden rod fixed across a corner of the room at a suitable
height.
6. KINDS OF 3D MEDIA
Objects
Concrete materials such as plants, animals, tools and
artifacts used in providing direct experience.
7. • Specimens
Part of aspects of some items that is typical of
characters of others in its same class or group.
8. Points to consider in using Objects
and Specimens for Teaching
Develop a purpose for using them
Provide opportunities for students to
manipulate or work with
Present just enough at a time
Present in a dramatic way
9. Advantages
Less abstract,
more concrete
Attracts attention
Students become
more familiar with
objects.
Limitations
• Need bigger
storage
• Prone to possible
damage
• Some have
limitation in
availability
10. Mock-up
Arrangement of real device or associated devices, displayed
in such a way that representation of reality is created.
11. Advantages
Learners can examine which may not be easy with the
real object
Learners can handle and operate
Create high interest and permit close-up observation of
how it works
Can provide learning experiences that real object cannot
provide
Can illustrate basic operation of a real device and provide
important details
Allow independent study
Make classroom discussion more effective
13. Models
Models (ie recognisable three-dimensional
representation of real things or abstract system)
Modified real things, reproductions of costly or delicate
items- replicas of real objects which may be larger or
smaller than the real thing
Useful in 3 specific roles, namely, as visual support
materials in mass instruction, as objects for study or
manipulation in individualized learning and as
construction projects for individuals, small groups or even
entire classes.
14. Application of models
They can be used to reduce very large objects and enlarge
very small objects to a size that can be conveniently
observed and handled.
They can be used to demonstrate the interior structures
of objects or systems with a clarity that is often not
possible with two-dimensional representations.
Can be used to demonstrate movement- another feature
that is often difficult to show adequately using two-
dimensional display systems.
Can be used to represent highly complex situation or
process in a simplified way that can be easily be
understood by learners.
15. TYPES OF MODELS
SOLID MODELS
Used mainly for recognizing external features.
CROSS-SECTION MODELS
Show the internal structure
18. Making your own models
Use of commercially-available kits of parts
Use of construction systems
Use of inexpensive materials such as
cardboard, hardboard, wood and wire up
static models of all types.
Use of materials like modelling clay to
produce realistic models of animals etc.
Use of materials like Plaster of Paris and
papier mache.
19. When making and using models
keep the following ideas in mind:
-Models must be factually correct.
- The audience must be able to understand the scale
of a model.
- Construction should be sturdy and simple.
-Store carefully.
- Involve the audience.
