Education Systems Change
Over Time
- This chapter contains a very brief
history of education in the United States. The emphasis
is on how education has changed in the past; the
suggestion is that it will change in the future. The
chapter includes a specific focus on computers as an aid
to both communication and thinking. Such uses of
information technology underlie major changes that will
occur in our educational system.
Overall
Goals of Education
- David Perkins' book (1992) contains
an excellent overview of education and a wide variety of
attempts to improve our educational system. He analyzes
these attempted improvements in terms of how well they
have contributed to accomplishing the following three
major goals of education:
- Acquisition and retention of knowledge and skills.
- Understanding of one's acquired knowledge and
skills.
- Active use of one's acquired knowledge and skills.
(Ability to apply one's learning to new settings.
Ability to analyze and solve novel problems.)
These three general
goals-acquisition, understanding, and use of knowledge
and skills-help guide formal educational systems
throughout the world. They provide a solid starting point
for the analysis of any existing or proposed educational
system.
The next three paragraphs expand on
the three goals stated by Perkins. These paragraphs
capture the essence of changes that Perkins, your author,
and many others feel are needed in our educational
system.
- Acquisition and retention. The totality of
human knowledge is increasing exponentially. Estimates
of the doubling time vary, with some people suggesting
a doubling of knowledge every 5 years, and some
suggesting an even shorter doubling time. The amount
of knowledge that one can acquire and retain is a very
tiny fraction of the totality of human knowledge-and
this fraction is rapidly decreasing. An alternative to
trying to acquire more information is to develop the
skills of a research librarian. Learn to make
effective use of the emerging global libraries that
can be accessed by use of computer networks.
- Understanding. Rote memory is no substitute
for understanding. Similarly, the ability to retrieve
information is no substitute for understanding what
one retrieves. Our educational system must
substantially increase its emphasis on understanding
and on higher-order thinking skills.
- Active use of knowledge and skills.
Information technology in schools empowers students.
Given appropriate opportunities and facilitation,
students can learn to make second-order effect uses of
a wide variety of information technology. Thus,
students can accomplish tasks and solve problems that
were beyond the capabilities of adults before the
information technology became available. Students can
address real-world problems and produce useful
results.
Education
in the United States
- July 4, 1776, was the date of the
signing of the Declaration of Independence. It was the
dawn of a new nation-the United States of America. At the
time of the Revolutionary War, the United States was an
agrarian country. Fully 90% of the people lived and
worked on farms.
Thomas Jefferson was one of the main
writers of the Declaration of Independence. He went on to
become the third president of the United States. He was a
broadly educated man, an inventor, and a visionary.
One of Jefferson's visions was for a
greatly improved educational system. In his home state of
Virginia, he envisioned and worked toward an educational
system that included primary schools that were readily
accessible to students. In his plan, 3 years of grammar
school would be available to all citizens, with the state
paying the tuition for families that could not afford the
tuition. (Slaves were not considered to be citizens. Note
also that the intent was that the schools would only be
free to those who could not afford tuition charges.)
Students could continue beyond the 3
years of schooling, at their families' expense. In
addition, the state would pay the tuition for a modest
number of boys that displayed great academic
potential. These ideas were far too revolutionary for the
time, and they were not implemented.
The next hundred years saw slow but
steady progress toward an increasing number of students
receiving an increasing amount of education. While a
grammar school system was well established, relatively
few students progressed beyond that level. In the 1870s
the high school graduation rate in the United States was
only about 3%. The United States was still an agrarian
nation and education at the high school level or above
was for the elite.
Indeed, in 1890, well under 10% of
high school aged students were actually enrolled in a
high school. In 1890 Harvard president Charles W. Elliot
noted that of the 352 students admitted to Harvard the
previous year, only 97 came from public high schools.
Since most of these Harvard students were from the state
of Massachusetts-the state that probably had the nation's
best public educational system-these data suggest that
the public educational system left much to be
desired.
However, in the late 1800s, the
United States was industrializing. Industrialization
brought with it increasing educational demands. Many of
the main ideas and components of our current educational
system were developed and implemented during that
time.
In the years that followed, there
was a substantial increase in public secondary school
education. States began to fund such systems and
established requirements for attendance. People debated
how much schooling should be required. They also debated
college-preparation types of curriculum versus
vocationally-oriented types of curriculum. In those days,
college preparation included a substantial amount of
studies in Latin and Greek.
The secondary school curriculum that
gradually emerged bears a striking resemblance to the
secondary school curriculum of today. Although there were
no national standards, a relatively common core of
courses became available at schools throughout the
country. The idea of the Carnegie Unit (a year-long
course meeting one period a day) was developed. Many
colleges throughout the country began to base college
admission on students having successfully completed a
number of Carnegie Units of coursework from a basic core
of nine different subject areas.
During the past half century, the
high school graduation rate in the United States has
steadily increased, as has the number of students going
on to college. This is also true for much of the rest of
the world. Improvements in transportation and
communication have made it easier for the educational
systems in the various countries to build upon ideas from
other countries and to compare themselves to educational
systems in other countries. We are seeing the gradual
development of worldwide goals and worldwide standards
for education.
Reading,
Writing, and Arithmetic
- Reading, writing, and
arithmetic-the three R's-have long been considered to be
the basics of education. Thomas Jefferson understood that
even 3 years of grammar school instruction in the three
R's can produce a useful level of skills. That is because
even a rudimentary level of knowledge and skills in the
three R's allows one to make use of knowledge that has
been stored in books. That is, one can build on the
accumulated knowledge of the writers in solving problems
and accomplishing tasks.
The three R's empower people in a number of different
ways. For example:
- The three R's are an aid to communication.
- The three R's are an aid to the human mind. They
help to overcome limitations of the human mind such as
limitations of short-term and long-term memory. (Have
you ever tried to do long division in your head?)
- The three R's have made possible a steady
accumulation of human knowledge in a form that people
throughout the world can access and use. For example,
probably you studied Euclidean geometry when you were
in high school. Euclidean geometry is a type of
mathematics developed about 2,000 years ago.
It takes a great deal of time and
effort to develop a useful level of skills in the three
R's. What constitutes a "useful level" has gradually
increased over the years. While universal third grade
education was considered too revolutionary in Thomas
Jefferson's time, it is now totally inadequate. Our
formal educational system has a major focus on the three
R's that continues even on into college, where most
freshmen are required to take writing and math
coursework.
Information technology is adding new
dimensions to the three R's. Writing with pen and ink is
different than writing with a word processor and desktop
publication system with a built-in outliner, a spell
checker, and a laser printer. This, in turn, is but one
step toward developing effective interactive hypermedia
documents that make use of text, color, graphics, audio,
and video.
Computer-based information systems
can be used to store books. However, consider the new
dimension that is added when one can store both "how to
do it" information and have a computer system that can
actually "do it." The handheld graphing calculators that
are now commonly used in high school math and science
classes provide a simple example. Such calculators
contain a large number of built-in functions and can
automatically produce the graph of a function. Many such
calculators also have a "Solve" key. That is, there is a
program built into the calculator that can automatically
solve an equation that has been entered into the
calculator. Stated slightly differently, the calculator
stores information about graphing functions and solving
equations-and it can automatically carry out the work of
graphing a function or solving an equation. Needless to
say, the capabilities of a modern microcomputer far
exceed those of such handheld calculators.
Reading, writing, and arithmetic are
not about to go away. Instruction in these mind tools
will continue to be a central focus in education.
However, the environment for learning and using these
mind tools is changing. An increasing number of students
are learning to use information technology at the
earliest grade levels-indeed, many students are learning
to use these tools before they enter school. Many
students are growing up in computer-rich environments.
They have good access to information technology at home,
and they have had excellent one-on-one instruction from
parents who are computer professionals, or who make
routine use of computers at work. It is evident that
there is a marked difference between such students and
those who are obtaining the modest amount of information
technology instruction and use that our schools are
currently providing.
Information
Technology in Schools
- In 1982, our K-12 schools had
approximately one microcomputer or timeshared computer
terminal for every 125 students. In 1995, the ratio had
improved to approximately one microcomputer per nine
students. At the time this book was being written, the
ratio had improved to approximately one microcomputer per
eight students.
In the past few years, information
technology in education has become part of the national
political agenda.
Clinton Proposes
Computers In All Classrooms
It is inevitable that students will
be provided with steadily improving computer facilities
and connectivity. Although the current pace of change in
schools seems slow relative to what has been occurring in
business and industry, it is torrid relative to the pace
of change that schools are used to. And, there are strong
pressures to step up the pace of implementation of
information technology in education.
The goals that Clinton has listed
are both modest and inadequate. They do not adequately
reflect information technology as a natural extension of
the three R's. A goal of one computer per four or five
students is somewhat like a goal of one pencil and one
book per four or five students. The educational benefits
that can come from information technology will only occur
when students are able to have routine access to the
technology, in the same way that they now have routine
access to pencil, paper, and books. The goal must be
adequate facilities, curriculum, and instruction to move
all students into routine second-order level uses of the
information technology.
Conclusions
and Recommendation
- The educational systems of the
world and of the United States have changed substantially
over the years. To a large extent, the changes have been
driven by changes in science and technology. The movement
has been toward ever increasing levels of knowledge and
skill for all students.
The current educational system in
the United States is strongly rooted in meeting the needs
of an Industrial Age society. However, the United States
is no longer an Industrial Age society; it is an
Information Age society.
The typically-suggested changes for
technology in schools-for example, the Clinton agenda-are
rooted in Industrial Age thinking. This thinking
envisions a computer as a tool that one "goes to" and
uses occasionally, somewhat like people used to use
mainframe computers. The Clinton agenda does not provide
for every student to have routine access to powerful
computers and high bandwidth connectivity. It does not
envision students routinely making second-order level
uses of the technology.
The next chapter contains an
overview of computer and communications technology in
education.
