This document discusses various types of 3D instructional media that can be used for teaching, including their advantages and limitations. It covers objects and specimens, models and mock-ups, dioramas, and puppets. For each type, it describes what they are, provides examples, and discusses how they can be used effectively in the classroom and considerations for their use. Principles for selecting and utilizing resource speakers are also outlined.
3. Specimens
- a part or aspect of some
item that is a typical
sample of the character of
others in its same class or
group
- enable us to learn many
things that would
otherwise be unobtainable
4. Points to Consider in Using Objects and
Specimens for Teaching
1. Develop a purpose for using them
2. Provide opportunities for students to work with or to
manipulate
3. Present just enough at a time
4. Present in a dramatic way
5. Advantages
1. less abstract, more concrete
2. attracts attention
3. students become more familiar with objects
Limitations
1. need bigger storage
2. prone to possible damage
3. some have limitation in availability
6. Models and Mock-ups
Models
- modified real things, reproductions of costly or
delicate items
- replicas of real objects which may be larger or
smaller than the real thing
- can be made to show interior view of objects and
they can be simplified to any extent desired in order
that the basic concept represented may be
communicated most adequately
7. Varied Purposes of Models
1. when real objects are too small or too large to bring
into the classroom
2. to present subject matter involving the past and the
future
3. physical inaccessibility
4.abstract construction
5. to explain processes
8. Types of Models
1. Solid Models
- used mainly for
recognizing external
features
12. Mock-up
- arrangement of a real device
or associated devices,
displayed in such a way that
representation of reality is
created
- may be simplified in order
to emphasize certain features
- a special model where parts
or a model is singled out,
heightened, and magnified in
order to focus on that part
13. Advantages
1. Learners can examine which may not be easy with
the real object
2. Learners can handle and operate
3. Create high interest and permit close-up
observation of how it works
4. Can provide learning experiences that real objects
cannot provide
5. Can illustrate basic operation of a real device and
provide important details
6. Allow independent study
7. Make classroom discussion more effective
14. Limitations
1. Require tedious work
2. Expensive
3. Might distort some real concepts
4. Big or heavy models may be difficult to handle for
actual lecture
15. Diorama
- of Greek origin which means “to see through”
- a 3D representation of events, ideas or concepts
against a scenic background
- miniature scene in 3D treatment meant to replicate
reality
16. Principal Parts of Diorama
Painted
Background
Case or
Stage
3D Middle
and
Foreground
Objects
17. Advantages
1. Have intrinsic value
2. Allow us to compare past and present conditions
3. Help us make connections to the real world
4. Develops students’ creativity
5. Can be viewed, handled, and examined by
students
6. Adds interest and meaning to the lesson
18. Limitations
1. Demands a bigger space in terms of use and
storage
2. Expensive
3. Easily damaged
19. Puppets
- are artificial figures whose movements are controlled
by a person
- are moved by hand, strings, wires or rods
- are made to represent a person, animal, plant or an
object
20. Types of Puppets
1. Shadow Puppets
- 2D in nature,
normally controlled
by rods that are much
thinner than the
typical ones that are
used to support the
rod puppet
- makes use of a
translucent screen
and a light source
21. 2. Rod Puppets
- flat, cut-out figures tacked
on a stick, with one or more
movable parts and operated
from below the stage level by
wire or slender sticks
22. 3.Hand Puppets
- made to slip over the
hand like a glove
- puppet’s head is
operated by the
forefinger, the little finger
and thumb are used to
animate the puppet’s
hands
24. 5.Marionettes
- suspended and
controlled by a number of
strings, plus sometimes a
central rod attached to a
control bar held from
above
- generally constructed of
wood with articulating
joints that replicate those
of human beings
- requires greater
manipulative control than
an finger, glove or rod
puppet
25. Advantages
1. Boost active participation among students
2. Stirring and attention-getting
3. Fascination of the inanimate objects
4. Enjoyable and spontaneous learning experience
5. Students become more creative
Limitations
1. Time consuming
2. Expensive
3. Demands extra effort
4. Can compete with the teacher
26. Principles in Choosing Puppet Play
for Teaching
1. Do not use puppets for plays that can
be done just as well or better by
another dramatic means
2. Puppet play must be based on actions
rather than words
3. Keep plays short
4. Do not omit the possibilities of
music and dancing as part of the
show
5. Adapt in all respect to your audience
6. Do not hesitate to adapt puppet play
27. Resource Person – someone
invited to talk about
something
Consider the following when
inviting and using a resource
speaker:
1. engage the expert
2. clarify the purposes of the
visit
3. subject should be of
educational relevance and
value to the students
28. Consider the following when
inviting and using a resource
speaker (cont.):
4. speaker should not tend to
disrupt the educational
program
5. info to be discussed should
be appropriate to the age and
maturity of students
6. teacher should remain in
the classroom throughout the
presentation
29. Introducing the Speaker/s
1.Prepare what you are going to say
2. Follow the TIS formula
T – topic / title of speaker’s talk
I – importance of the topic
S – speaker’s outstanding qualifications
3. Announce speaker’s name distinctly and clearly
4. Be enthusiastic about the speaker
30. Things to Remember when Invited as a
Resource Speaker
1. Restrict subject to fit the time at your disposal
2. Arrange ideas in sequence
3. Enumerate points as you make them
4. Compare the strange with the familiar
5. Turn a fact into a picture
6. Avoid technical terms
7. Use appropriate media
8. Speak with contagious enthusiasm
9. Show respect and affection to your audience
