REALIA & MODEL

PRESENTED BY

Md. Kabir HossainIER

REALIA1. ‘REALIA’ REFERS THAT , ANY REAL OBJECTS

WE USE IN THE CLASSROOM TO BRING THE

CLASS TO LIFE.

2. ANY OBJECTS OR ACTIVITIES USED TO

RELATE CLASSROOM TEACHING TO THE REAL

LIFE ESPECIALLY OF PEOPLES STUDIED.

From

Dale’s Cone of Experience

we know that“Learning

happens through actual hands-on

experiences”

ADVANTAGES The main advantage of using real objects into the

classroom is to make the learning experience more memorable for the learner.

Visually interesting and captures the attention of the learner.

Break from typical class activities.  Realia saves time. Realia breathes life into new vocabulary. Students will try to use real material to understand

anything.

DISADVANTAGES• Real objects may not support a cultural

distinction.

• Activities with real object might lose the class

path.

• Spending too much time in one activity with real

objects in the classroom.

MODEL

1. A MODEL IS A REPRESENTATION OF AN IDEA,

OBJECT, EVENT, PROCESS OR SYSTEM.

2. MODEL ARE REPLICAS OR COPIES OF REAL

OBJECTS WITH SUITABLE CHANGE IN SIZE,

COMPLEXITY, TIMING, SAFETY AND COST

FACTORS.

WHEN WE SHOULD USE ? When real objects are too small or too large to bring into

the classroom. Physical inaccessibility Abstract construction To explain processes

ADVANTAGES The Models provide an environment for interactive

student engagement Learner can examine which may not be easy with the real

object Learner can handle and operate Create high interest and permit close-up observation of

how it works Can illustrate basic operation of a real device provide

important details Make classroom discussion more effective

DISADVANTAGES• Require tedious work

• Expensive

• Might distort some real concepts

• Big or heavy models may be difficult to handle for actual

lecture
