Education for an
Age of Technology
By William A. Wulf
Think about how many recent stories in
this newspaper have involved technology. Communications satellites in China. Disputes over
Internet browsers. Observations of unusual weather patterns. We live in a society that is
addicted to technology. In fact, we are addicted to technological change and to the belief
that technology will make things better tomorrow than they are today.
At the same time, many people are, for
the most part, ignorant of how technologies work, even though major policy decisions are
made every day that are either affected by or affect technology. Thats a dangerous
combination.
Every citizen ought to be
technologically literate. This includes not only scientific and mathematical literacy, but
also understanding the economic, social, and political roles that technology plays in
society and the process by which technology is created. Yet scientific and mathematical
literacy are seen as important educational objectives in the United States, and
technological literacy is not.
Students in our elementary, junior
high, and high schools rarely get more than a passing exposure to how devices are designed
and operate. The consequences of this neglect can affect people their whole lives, from
irritation with common appliances to an inability to participate intelligently in
decisions about some of the most important issues of our day. People dont need to
know all the specifics of a particular technology. But they should know enough of the
facts and processes by which a technology was engineered to make rational, common sense
decisions.
An analogy with science is helpful
here. The word "science" is actually used in two different ways. One refers to
the body of scientific knowledge. The other refers to the process of discovery. The fact
that the Earth circles the sun in one year is part of the body of knowledge. How we know
this, however, is the result of generating hypotheses, making observations, and conducting
experiments that tested the hypotheses.
All too often, science education has
meant only communicating the body of knowledge. Thats why so many science courses
are so dull. As my colleague Bruce Alberts, president of the National Academy of Sciences,
points out, students are expected to learn more new words in the average freshman biology
course than they are in a foreign language course.
Worse than dull, this approach is
incomplete. Science is more than specific knowledge. It is the process through which we
validate what we know. This hands-on aspect of science is why the National Science
Education Standards released two years ago emphasize inquiry-based instruction.
Technological literacy has many
parallels to science literacy, but the terminology is different. Technology is the body of
knowledge. The process of developing technologies is engineering. To be technologically
literate, school children need to understand both the process and the products of
engineering. They should be able to use basic mathematics and science skills to design
solutions to problems. They also should be familiar with the methods that engineers use to
evaluate design alternatives in search of the one that best satisfies constraints related
to cost, functionality, safety, reliability, manufacturability, ergonomics, and
environmental impact.
Discussions of technology literacy
often focus on a single subjectthe use of computers in schools. Admittedly,
computers and the Internet are important educational tools, but equating the use of
computers with technological literacy is far too limited a view, given the extent to which
technology has transformed our lives. Making kids "as comfortable with a keyboard as
a chalkboard," as President Clinton put it in a recent speech, is a key aim of a
technologically literate society. But it is only one element of a much broader goal.
The United States has good national
standards for science and mathematics education. Comparable attention now needs to be
devoted to the other components of technological literacy. Standards for what is known as
technology education are now being developed, but technology education need not be a
separate course in schools. Considerations of technology should be integrated into
mathematics, science, history, language arts, and other topicsas is the case in real
life.
People rely on technology for
transportation, communication, medical care, entertainment, the food they eat, the
clothing they wear, the buildings they use, and the work they do. Ignorance about such a
fundamental feature of modern life is not healthy for individuals or for societies.
