21. What is Technology?
It is the innovation, change, or
modification of the natural
environment in order to satisfy
perceived human wants and needs.
(Standards for Technological
Literacy, ITEA, 2000)
The goal of technology is to make
modifications in the world to meet
human needs. (National Science
Education Standards, NRC, 1996)

22. What is Technology ? (Continued)
In the broadest sense, technology
extends our abilities to change the world:
to cut, shape, or put together materials; to
move things from one place to another; to
reach farther with our hands, voices, and
senses. (Benchmarks for Science Literacy,
AAAS, 1993)
Technology is the process by which
humans modify nature to meet their
needs and wants. (Technically Speaking:
Why All Americans Need to Know More
About Technology, NAE/NRC,2002)

23. Updated Definition of Technology
• Technology is the modification of the natural world to meet to
human wants and needs. It helps us to improve our health; to
grow and processed food and fiber better; to harness and use
energy more efficiently; to communicate more effectively; to
process data faster and accurately; to move people and things
easier; to make products to enhance our lives; and to build
structures that provide shelter and comfort.

24. What is Engineering?
“Design under constraint. Engineers design solutions to
problems. However there are a set of constraints that we
have to satisfy -- size, weight, reliability, safety, economic
factors, environmental impact, manufacturability, and a
whole list of “--bilities” (Wulf)
the profession in which a knowledge of the mathematical
and natural sciences gained by study, experience, and
practices are applied with judgments to develop ways to
utilize economically the materials and forces of nature for
the benefit of mankind. (Accreditation Board for Engineering
and Technology (ABET, 2002)
