Transcript of Three-Dimensional (3D) Instructional Media

Different Instructional 3D Materials 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”.
What is a Three-Dimensional (3D) Instructional Media? Different Instructional 3D Materials Objects and Specimen
Models and Mock-ups
Puppets
Dioramas
Plays and Exhibits
Artifacts 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:
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.
Models and Mock-Ups
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.
Models 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.
Allow learner to examine model or mock-up which may not be easy in the real object.

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.
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.
PUPPETS
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
Types of Puppet Shadow Puppet
Hand Puppet
Rod Puppet
Glove and Finger Puppet
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
