3. Technology is come from Greece word techne is the
collection of techniques, methods or processes used in
the production of goods or services or in the
accomplishment of objectives, such as scientific
investigation.Technology can be the knowledge of
techniques, processes, etc. or it can be embedded in
machines, computers, devices and factories, which can be
operated by individuals without detailed knowledge of
the workings of such things.
4. Technology has been a dialectical and
cumulative process at the center of human
experience. It is perhaps best understood in
a historical context that traces the evolution
of early humans from a period of very simple
tools to the complex, large-scale networks
that influence most of contemporary human
life. For the sake of simplicity, the following
account focuses primarily on developments
in the Western world, but major
contributions from other cultures are also
indicated.
5. Many historians of science argue not only that
technology is an essential condition of
advanced, industrial civilization but also that the
rate of technological change has developed its
own momentum in recent centuries.
Innovations now seem to appear at a rate that
increases geometrically, without respect to
geographical limits or political systems. These
innovations tend to transform traditional
cultural systems, frequently with unexpected
social consequences. Thus technology can be
conceived as both a creative and a destructive
process.
6. TECHNOLOGY IN EDUCATIONTECHNOLOGY IN EDUCATION
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.
7. SCIENCE AND TECHINOLOGYSCIENCE AND TECHINOLOGY
The meanings of the terms science and
technology have changed significantly from
one generation to another. More
similarities than differences, however, can
be found between the terms.
8. Both science and technology imply a thinking
process, both are concerned with causal
relationships in the material world, and both
employ an experimental methodology that
results in empirical demonstrations that can
be verified by repetition (see Scientific
Method).
9. Science, at least in theory, is less concerned
with the practicality of its results and more
concerned with the development of general
laws, but in practice science and technology
are inextricably involved with each other.
The varying interplay of the two can be
observed in the historical development of
such practitioners as chemists, engineers,
physicists, astronomers, carpenters, potters,
and many other specialists.
10. Differing educational requirements, social
status, vocabulary, methodology, and types of
rewards, as well as institutional objectives and
professional goals, contribute to such
distinctions as can be made between the
activities of scientists and technologists; but
throughout history the practitioners of “pure”
science have made many practical as well as
theoretical contributions.
11. Science, systematic study of anything that
can be examined, tested, and verified. The
word science is derived from the Latin word
scire, meaning “to know.” From its early
beginnings, science has developed into one
of the greatest and most influential fields of
human endeavor. Today different branches
of science investigate almost everything that
can be observed or detected, and science as
a whole shapes the way we understand the
universe, our planet, ourselves, and other
living things.
12. WORLD OF SCIENCE Continental Drift
This landmark Scientific American article from
1963 heralds a profound turning point in
geology: the acceptance of continental drift,
or plate tectonics theory. Canadian
geophysicist J. Tuzo Wilson, one of the
architects of modern geologic thought,
summarized compelling evidence
