Educational Technology
• Educational technology is the effective use
of technological tools in learning. As a
concept, it concerns an array of tools,
such as media, machines and networking
hardware, as well as considering
theoretical perspectives for their effective
application.
Definitions
• According to the Association for
Educational Communication and
Technology (AECT, 2008) it is possible to
define educational technology as “the
study and ethical practice of facilitating
learning and improving performance by
creating, using and managing appropriate
technological processes and resources”
(Richey et al. 2008).
Engineers and social scientists
view of the term “technology”
Engineers, technicians, and technologists:
technology as a tool for material construction based
on a systematic engineering knowledge of how to
design artifacts
Social scientists:
technology as a process for material construction
based on the organization of knowledge for the
achievement of practical purposes and also based
on any tool or technique of doing or making by
which capacity is extended (Luppicini 2005).
Luppicini’s (2005) definition
• Educational technology is a goal oriented
problem solving approach utilizing tools,
techniques, theories, and methods from
multiple knowledge domains, to
• (1) design, develop, and evaluate, human
and mechanical resources efficiently and
effectively in order to facilitate and leverage
all aspects of learning, and
• (2) guide change agency and transformation
of educational systems and practices in order
to contribute to influencing change in society
Scope of Educational Technology
• Educational technology thus refers to the use
of both physical hardware and educational
theoretics
• It encompasses several domains, including
• learning theory,
• computer-based training,
• online learning, and,
• where mobile technologies are used, m-
learning
The scope can be accessed from the
following points:
1. Determination of Objectives
2. Improvement in Teaching Learning Process
3. Development of Teaching Learning Material
4. Improvement in Teaching Training
5. Development of Teaching Learning Strategies
6. Proper Use of Audio Visual Aids
7. Utilization of the Sub-System of Education
8. Development of Curriculum
9. Proper Use of Hardware and Software
10. Provides Feedback

Media
Projected
• Refers to those aids where a bright light is
passed through a transparent picture by
means of a lens and an enlarged picture is
thrown or projected on the screen.
Types of projected aids
• OHP
• Digital Projectors
• Laptops & Computers
• Power Point Slides
• Film Strips
Over Head Projector
• It consist a glass area with a transparent
glass covering onto which light is focused
from below. A Projector lies above this
base (over the head) which magnifies the
light coming from below and projects it
onto the desired point.
• Advantages
– Easy to handle
– No necessary for darkened room
– easy to transport
• Limitations
– Depends on power
– Straining the eyes
• A Digital Projector / video projector is
an image projector that receives a video
signal and projects the corresponding
image on a projection screen using
a lens system.
• IT has HDMI (High-Definition Multimedia
Interface) Portal that can connect the
laptop or computer with them.
Computers & Laptops
• Computers & laptops revolutionized the
way things are done in any field.
• Vital for making presentations, computer
programming languages
• Internet knowledge
Power point Slides
• A collection of pages arranged in
sequence that contain text and images for
presenting to an audience. It often refers
to a Microsoft PowerPoint presentation.
See presentation graphics,
PowerPoint and slide transition.
Film Strips
Film strip projector
Film strips
• The filmstrip was a common form of still
image instructional multimedia, once

• Filmstrips provided an easy and
inexpensive requiring very little storage
space and being very quick to rewind for
the next use. Filmstrips were large and
durable, and rarely needed splicing.
Non- Projected
• Those aids which do not require projector,
projection screen or electricity.
• Can be simply shown , hung on the wall,
touched and handled by any learner
2D- Non –Projected Aids
• Blackboard/ Chalkboard
– a reusable writing surface on which text or
drawings are made with sticks of calcium
sulphate or calcium carbonate,
– Blackboards were originally made of smooth,
thin sheets of black or dark grey slate stone.
– Modern versions are often green because the
colour is considered easier on the eyes.
Advantages
• Cheap
• No power dependence
• Can be used in broad day light
• No maintenance costs
• Mistakes can be corrected instantly
Graphs
• Graph is defined as a visual
represanatation of numerical data. Graph
is fundamentally a tool for expressing
number relationships, which is much
easier to visualize that can be done if the
statement were made only in words and
figures
Types of graph
• Line graph
Bar graph
CirclePie graph
Pictorial Graph
Maps
• Maps constitute and indispensible aid in

students in the class
• The teacher often does not take effort to
teach map reading to the students.
• Each type of map should have the
relevant details.
Charts
• A chart is a combination of pictorial,

show relationships such as comparisons,
relative amounts, developments,
processes, classification and organization.
Advantages
• Present matter symbolically
• Present abstract ideas in visual form
• Summarizes information
• Shows relationships by means of facts,
figures and statistics
Posters
• A poster is any piece of printed paper designed to
be attached to a wall or vertical surface. Typically
posters inculde both textual and graphic elements
although a poster may be either wholly graphical
or wholly text. Poster are designed to be both
eye-catching and informative. Posters may be
used for many purposes. They are a frequent tool

Flash cards
• Flash cards are used for presentation of
an idea in the form of posters, pictures,
words and sentences. A single card or a
whole series may be flashed in front of the

comprehension and retention
Advantages of Flash card
Easy to carry
Pictorial contents presented in a series
are easily recognized by the group
Limitations
• The students cannot get the complete
view of the concept
3D Teaching Aids
Models
Models are used for demonstrating the
three dimensional representation of real
things or abstract things. They can be
used in a wide range of instructional
situations.
They are particularly used for some specific
purpose
• As visual support material in instruction
• As a objects for study or manipulation in
individualized learning
Advantanges
• They can reduce very large objects to a
size that can be conveniently observed
and handled by students
• They can be used to demonstrate the
interior structures of objects or systems
with clarity

  • 4. Engineers and social scientists view of the term “technology” Engineers, technicians, and technologists: technology as a tool for material construction based on a systematic engineering knowledge of how to design artifacts Social scientists: technology as a process for material construction based on the organization of knowledge for the achievement of practical purposes and also based on any tool or technique of doing or making by which capacity is extended (Luppicini 2005).
  • 5. Luppicini’s (2005) definition • Educational technology is a goal oriented problem solving approach utilizing tools, techniques, theories, and methods from multiple knowledge domains, to • (1) design, develop, and evaluate, human and mechanical resources efficiently and effectively in order to facilitate and leverage all aspects of learning, and • (2) guide change agency and transformation of educational systems and practices in order to contribute to influencing change in society
