3 DIMENSIONAL MEDIA

                    

       THREE DIMENTIONAL MEDIA

                

OBJECTIVES: 

•  Analysis the characteristics of 3D instructional materials.
•  Create 3D instructional materials.
•  Demonstrate proper use of 3D instructional materials. 

THREE DIMENTIONAL MEDIA

• Display an additional quality that appeals to the since of touch-that is, a tactual quality.
•  Gives a right understanding of real things. 

3D INSTRUCTIONAL MATERIALS

        

•  Are 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 of teaching experiences.
• Are usually constructed to allow handling by the students, except does which are Too large, too costly, to rare, or to fragile. 

Pioneers in Education in their  Education Theory

1. Jean Piaget

             

 -Use the methods of instruction through the individualize program, exploration and experimentation with concert materials that helps the child to learn more about the environment. With use of real things, a child is able to compare or contrast  things  and make perception about his environment.

2. Maria Montessori

             

       -Using real things help promote motor and sensory skills.

3. Jerome Brunner

         

       - Proposes that instruction should proceed from direct experiences  ( real things)  to iconic representation (pictures) to symbolic representation  (words) for achieving mastery of task.

KINDS OF 3D’S
1. Object and Specimens
2. Models and mock-ups
3. Diorama
4. Puppets
5. Resource Person 

1. OBJECTS and SPECIMENS

     

Objects… - Are concrete materials such as plants, animals, tools and artefacts used in providing direct experience.

Specimens… -Is a part of aspects of some items that is a typical sample of characters of others in its same class  or group. In biology, a specimen is an individual animal, part of  an animal, plant, parts of a plant, or  Microorganism used as representative to study the properties of the whole population of  that species  or subspecies.

Points of Consider of Teaching 

• Develop a purpose for using them.
• Provide opportunities ton learners to work with or to manipulate the  specimens so that they can  consider concepts, process and principles  by themselves.
• Present just enough  specimens or object at a time so as not to overwhelm the learner.
• Presents the materials in a dramatic way so as to arouse and sustain the interest  of the learners 

ADVANTAGES:

•   These are less abstract and more concrete.
•  It attracts learners attention.
•  Learners become more familiar with objects.

LIMITATION:

•  Needs a bigger stories. 
•  Prone to possible damage.
• Some object has limitation in availability and may not be easy to be found. 

2. MODELS and MOCK-UPS

   

MODELS

     -are scaled replicas of real object. Show the totality of a thing or a process.

Examples:  

 -models cars
 -airplanes
 -house
 -Solar system

MOCK-UPS 

     -are special types of models which are focused on a specific part of a whole object and are workable.It is intended to show the essential parts which are made  detachable.

TYPES:

1. Solid Models - are mainly used for recognizing external features as in the case of globes and puppets.

             

2. Cross-section Model/cut away  Models  - Show the internal structures.

            

3. Constructional Model- which can be assembled and disassembled to show relationship of parts to whole.

                    

4. Working Models- indicates how the things being represented operates.

                  

ADVANTAGES:

• Allow learners to examine models or mock-ups which may not be easy in the real object
• Functional model/mock-ups allow learners to handle and operate.
• After presentation, model can be left on display for a period  of times and allows learners display for a period of times and allows learners to independently study the item at their own convenience.
• Can provide learning experiences that real objects cannot provide.
• Working models can illustrate  basic operations of a real device and provide important details.

WHEN TO USE:

• When reality is too small.
• When reality is inaccessible (past and futuristic events and when distance is impossible to bridge).
• When reality is to dangerous (like viewing an erupting volcano).
• When reality is unreliable (weather and other climatic conditions).
• When reality is too abstract (face relationship, mathematics).

DISADVANTAGES

• It may be more expensive that extra care is needed.
• Some models which are too big may be difficult to handle for the actual lecture.
• If models are built to scale. It could be time consuming.
• It might distort some real objects.

3. DIORAMA

             

     The term diorama is a 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.

     A three dimensional representation of events, ideas or concepts against a scenic Background.

     Are portable meaningful exhibit in boxes or cases.

     A miniature scene in 3D treatment that is meant to replicate reality and cause students to think creatively.

Four Principal Parts:

• The case or stage.
• The painted background.
• The three-dimensional middle in foregrounds.
• The figures, constructions, and modeled objects that are placed in the case.
