Educational technology refers to the process of integrating technological tools and materials into education for instructional purposes. It involves applying both instructional procedures and instructional tools. While technology was once thought of primarily as computers and gadgets, educational technology focuses more broadly on applying any tools to further educational goals. Educational technology encompasses areas like instructional systems, vocational training, computers and computer-based systems. Current educational technology includes standalone PCs, networked computer systems, instructional software, interactive materials and distance learning courses.

Concepts and Definitions
Educational Technology has no
agreed upon definition.

4. “Technology is commonly
thought of in terms of gadgets,
instrument, machines, and
devices….most (educators) will
defer to technology as
computers”
-- Muffoletto(1994)-p.5 Integrating Education-- Muffoletto(1994)-p.5 Integrating Education
Technology into Teaching (IETIT)Technology into Teaching (IETIT)

5. ““Only about a decade ago, a
history of technology in
education since 1920 placed the
emphasis on radio and
television, with computers as
an afterthought .”
--Cuban, 1986--Cuban, 1986 (IETIT) p.5

6. However, Saettler (1990) urgesHowever, Saettler (1990) urges
“The historical function of“The historical function of
educational technology is aeducational technology is a
processprocess rather than a product.”rather than a product.”

7. Any useful definition of
educational technology, therefore,
must focus on the process of
applying tools for educational
purposes, and the materials used.

8. In education, the combination of
process and product merges
instructional procedures with
instructional tools.

28. The CPU’s StepsThe CPU’s Steps
Step 1.
The controller gets an instruction
from the system’s internal memory
and puts it in a register.
Step 2.
The controller directs the ALU to do
necessary computations.
Step 3.
The controller gets the result from the
register and stores it once again in

ALU : stands for Arithmetic/Logic
Unit
Control Unit: directs the activities of
the whole system.

The internal memory functions:
A limited amount of space is
arranged inside the computer for
