Three-Dimensional (3D) Instructional
Media
What is a Three-Dimensional (3D)
Instructional Media?
It display an additional quality that appeals to the sense of touch – that is, a
tactual quality. Their most important
characteristic is their idea that they are to be handled by students to further assist them in formulating more legitimate concepts about
things.
Three-dimensional materials are very useful in
the event that real-life materials are impossible to
be brought in the classroom to provide students with certain
amount of direct, purposeful, rich, and meaningful learning
experience in accordance with Dale’s “Cone of
Experience”.

Objects and Specimen
Objects are concrete materials such as plants, animals, tools, and
artifacts used in providing direct experience.
Specimen is a part or aspect of some item that is typical sample of the
character of others in its same class or group. Specimens enable us to
learn many things that would otherwise be unobtainable.
Objects and specimens enable us to build generalizations that would
otherwise cost prohibitive amounts of time and effort.
Advantages & Limitations
Points in Using Specimen and Obects in
Teaching
Advantages• These are less abstract and more concrete.• It attracts students’ attention.• Students become more familiar with objects.
Limitations• They need bigger storage.• They are prone to possible damage.• Some objects have limitation in availability
and may not be easy to find.
The following are some points to consider in using specimen and objects for teaching:
• Develop a purpose for using them.• Provide opportunities to pupils to work or to
manipulate the specimens so that they can consider concepts, process and principles by themselves.
• Present just enough specimens or objects at a time so as not to overwhelm the students/pupils.
• Present the materials in a dramatic way so as to arouse and sustain the interest of the student/pupils.
Models and Mock-Ups
Definitions
Varied Purposes of Models
Types of Models
Advantages
Limitations
Models• Models are modified real things – reproductions of
costly or delicate items that can be provided at reasonable cost and are safe to use.
• They are replicas of real objects which may be larger or smaller than the real thing.
• Models are excellent for teaching concepts about things that are three-dimensional and concrete in nature.
• They can be made to show interior views of objects, and they can be simplified to any extent desired in order that the basic concept represented may be communicated most adequately.
Mocks-up
• A mock-up is an arrangement of a real device or associated devices, displayed in a such way that representation of reality is created.
• The mock-up may be simplified in order to emphasize certain features.
• It is also considered as a special model where the parts of a model are singled out, heightened and magnified in order to focus on the part or process under study.
Varied Purposes of Models
• When real objects are too small or too large to bring into the classroom.• To present subject matter involving
the past and the future.• Physical inaccessibility.• Abstract constructions.• To explain processes.
Types of Models
• Solid Models. They are used mainly for recognizing external features as in the case of globes and puppets
• Cross-section Model/Cut-away Models. They show the internal structures such as that of a tree showing the pith and other internal parts.
• Construction Models. They are models which can be assembled and disassembled to show relationship of parts to whole.
• Working Models. They indicate how the things being represented operate.
Advantages• Allow learner to examine model or mock-up which may
not be easy in the real object.• Functioning model/mock-up allows learner to handle and
operate.• Create high interest and permit close up observation of
how it works.• Can provide learning experiences that real objects
cannot provide.• Working models can illustrate basic operations of a real
device and provide important details.• Allow learner to independently study the item at their
own convenience.• Make classroom discussion more effective.
Limitations
• They require tedious work.• They are expensive.• They might distort some real concepts.• Some models which are too heavy or too big
may be difficult for actual lecture.
DIORAMA
The term Diorama is of Greek origin which means “to see
through”. Diorama is a three-dimensional representation of
events, ideas or concepts against a scenic background.
It is also known as a meaningful exhibit in boxes or cases, which
are portable.It is a miniature scene in three-dimensional treatment that is meant to replicate reality and
cause students to think creatively and aesthetically.
Four Principal Parts of Diorama
Advantages and Limitations
Four principal parts of dioramas
• The case or stage.• The printed background.• The three-dimensional middle and
foreground.• The figures, constructions, and modeled
objects that are placed in the case.
Advantages• They have intrinsic value.• They allow us to compare past and present
conditions.• They help us make connections to the real
world.• It develops students’ creativity.• It can be viewed, handled, and examined by
students.• It adds interest and meaning to the lesson.
Limitations
• It demands a bigger space in the classroom in terms of use and storage.
• It is generally expensive.• It is easily damaged.

Principles in Choosing a Puppet Play for
Teaching
Definition
• Puppets are artificial figures whose movements are controlled by a person.
• The person who operates them is called a puppeteer.• Puppets are moved by hand or by strings, wires, or
rods. Puppet figures are made to represent a person, animal, plant, or an object.
• A puppet can become the medium through which the children express themselves, often in role playing fashion. Puppets can assist the child in assuming the role of the character that he is portraying
Shadow Puppets
Rod PuppetsGlove-and-
Finger Puppets
Hand Puppets
Marionettes
Shadow Puppets
They are two-dimensional in nature, normally controlled by rods that are much thinner than the typical ones
that are used to support the rod puppet. This type of puppet makes use
of a translucent screen (rear-view screen) and light source for its effective
use.
Rod Puppets
They are flat cut out figures tacked to a stick, with one or more movable parts, and operated from below the stage level by wire rods or slender
sticks.
Hand Puppets
This type of puppet is made to slip over the hand like a glove. The puppet’s head
is operated by the forefinger of the puppeteer, the little finger and thumb are being used to animate the puppet hands.
Glove-and-finger Puppets
They make use of old gloves to which small costumed
figure are attached.
Marionettes
These puppets are suspended and controlled by a number of strings, plus sometimes a central rod attached to a control bar held from
above by the puppeteer. The control bar can be either a horizontal or vertical one. Basic strings for operation are usually attached to the head, back, hands (to control the arms) and just above the knee (to
control the legs). These are generally constructed of wood with articulating joints that replicate those of human beings. This form of puppetry is complex and sophisticated to operate, requiring greater
manipulative control than a finger, glove or rod puppet.
Advantages
• They boost active participation among students.
• Stirring and attention getting.• Fascination of the inanimate objects.• Enjoyable and spontaneous learning
experiences.• Students become more creative.
Limitations
• It is time-consuming.• It is expensive• It demands extra effort.• It can compete with the teacher.
Principles in Choosing a Puppet Play for Teaching
• Do not use puppets for plays that can be done just as well or better by another dramatic means.
• Puppets play must be based on action rather than words.
• Keep the plays short to ensure success.• Do not omit the possibilities of music and dancing as
part of the puppet show.• Adapt the puppet show in all respects to your
audience.• Do not hesitate to adapt the puppet play.

Introducing the Speaker/s
Things to remember when invited as a Resource Speaker
When delivering the talk
Advantages & Limitations
Things to be considered in inviting and using a resource speaker
Definitions
• A resource person is someone invited to talk about something. He or she is experienced or knowledgeable with and is capable of sharing what he or she knows.
• Engage the expert.• Clarify the purposes of the visit.• The subject is of educational relevance and
value to the students in that class.• The speaker (s) will not tend to disrupt the
educational program.• The information to be discussed is appropriate
to the age and maturity of the students.• Prepare the class.• The teacher is to remain in the classroom
throughout the presentation in order to ensure appropriate follow-up.
The following should be remembered in introducing speakers:
• Thoroughly prepare what you are going to say• Follow the TIS formulaT- stands for topics or the exact title of the speaker’s
talk.I- stands for the importance of the topic.S- stands for the speaker. It includes the speaker’s
outstanding qualifications, particularly those that relate to the topic.
• Announce the speaker’s name distinctly and clearly.• Be enthusiastic about the speaker.
Things to remember when invited as a Resource Speaker:
• Restrict your subject to fit the time at your disposal.• Arrange your ideas in sequence.• Enumerate your points as you make them.• Compare the strange with the familiar.• Turn in fact into the picture.• Avoid technical terms.• Use the appropriate media.• Speak with contagious enthusiasm.• Show respect and affection for your audience.• Begin in a friendly way
When delivering the talk
• Crash thoroughly your shell of self-consciousness.
• Don’t try to imitate others – be yourself.• Converse with your audience.• Put your heart into your speaking.• Practice making your voice strong and flexible.
Advantages• Less preparation on the part of the teacher.• Thorough discussion of the topic.• It might add enthusiasm to the audience if the
speaker is good.
Limitations• Hassle in searching for the suitable speaker.• It might confuse the audience if the speaker is not
good enough.• Less enthusiasm from the audience if the speaker
is boring.
