Edtech Lesson I

Evaluation of Educational Technology
and its Current Application
Evaluation means considering the
merits of the material used, its
strengths and weaknesses as a tool for
learning. It includes many aspects of
consideration like size, attractiveness,
relevance and economy, ease of
handling, novelty and practicality.
 Technology is the science of the
application of knowledge to practical
purposes in a particular field. It means
the totality of the means employed by a
group of people to provide itself with
the objects of material culture.
Educational Technology
 is the development, application and evaluation of
systems, techniques and aids to improve the process of
human learning (Council for Educational Technology for
the United Kingdom 1997).It is a systematic way of
designing, implementing and evaluating the total
learning and teaching process in terms of specific
objectives based on research on human learning and
communication and employing a combination of human
and non-human resources to bring about more effective
Information and Communications
Technology (ICT)
 refers to the use of electronic
communication system which has made
the sharing of information faster and
more effective. ICT tools refer to the
computer and its various applications
like word processing, PowerPoint,
excel, publisher, particularly the
Internet and the E-mail
Classifications of Educational
 Material Technology
1.Traditional or Low-Tech Instructional Materials are the
indigenous materials usually real objects or those that are made of paper
and cardboards. Pictures or photographs, illustrations, drawings,
cartoons, posters, graphs, charts, flash cards and maps done n paper are
examples of these
2.High-Tech Materials or the Mediated Technology includes
those which are presented using media equipment or hardware. This
includes the educational television, motion pictures, overhead projectors
(OHP), opaque projector, slide projector and more importantly the
computer and its peripherals like the LCD, printer and scanner.
 Non-Material Educational Technology on the other hand includes
the theories, laws, principles, methods and strategies of teaching. They
evolved as results of researches and studies in order to facilitate teaching
and learning.
More specifically, educational technology is very
useful in the classroom. If properly and selected
and used they can do the following:
 Arouse and sustain the interest and attention of the students
 Concretize concepts and ideas to promote meaningful
Mae learning more permanent by providing rich experiences
Provide self activities for independent learning
Increase one’s vocabulary by eliminating verbalism
Promote continuity of thought
Increase the quality of learning while decreasing the time
Check student’s preparedness
Make learning more interactive.
Procedures in Using Specific
Technology for Teaching
 Previewing.This step requires that the teacher should be
very familiar with the technology or the material he has
 Effective timing refers to the phase of the lesson where the
technology can best be used.
 Tying experiences together refers to the connection or
the relatedness that should be built between and among
experiences provided by various educational technologies.
 Re-view or Follow up. Is there a need for re-view or
follow up? The question can be answered by an evaluation of
the results of prior teaching.
Criteria in Evaluating Educational
 Size. The teacher must make sure that the text or the picture is seen very
clearly by the farthest pupils.
Relevance. The content of the educational technology must be related to the
learning task on hand and the maturity level and experiences of the pupils or
Color. Color adds life and attraction to the materials. Students and pupils are
fascinated with colors especially the bright ones. The materials can be more
effective if they are colorful.
Economy. Cheap but properly chosen educational technology can be effective
also as long as the teacher utilizes them alongside with pedagogical practices.
Durability. This refers to the length of time the material can be used over and
over again.
Easy to handle. Is the technology light, easy to put up and manipulate? Can it
be brought anywhere?
Novelty.This refers to the newness and uniqueness of the material.
