3Computers and Jobs
De-skilling
Up-skilling
4Productivity and People
- According to one study of 2,000 U.S. companies
that implemented new office systems, at least 40
failed to achieve their intended results. Most of
the failures were attributed to human or
organizational factors rather than technical
problems. - Many analysts argue that the most successful
computer systems are human-centered systems. Such
systems are designed to retain and enhance human
skills rather than take them away. - To create a human-centered system, systems
analysts and designers must understand the work
practices of the people wholl be using the
system.
5Computers and Job Quality
- Computer monitoring--using computer technology to
track, record, and evaluate worker performance,
often without the knowledge of the worker.
- Problems
- Privacy
- Morale
- Devalued Skills
- Loss of Quality
6Computers and Job Quality
- A typical data-entry shop might contain hundreds
of clerks sitting at terminals in a massive,
windowless room. - Workers - often minorities and almost always
female - are paid minimum wage to do mindless
keyboarding. - Many experience headaches, backaches, serious
wrist injuries, stress, anxiety, and other health
problems. - Optical character recognition and voice
recognition technologies will enable companies to
replace workers with machines.
7Employment and Unemployment
My father had worked for the same firm for 12
years. They fired him. They replaced him with a
tiny gadget this big that does everything that my
father does only it does it much better. The
depressing thing is my mother ran out and bought
one. --Woody Allen
8Employment and Unemployment
- Because of automation the unskilled, uneducated
worker may face a lifetime of minimum wage jobs
or welfare. - Technology may be helping to create an unbalanced
society with two classes a growing mass of poor
uneducated people and a shrinking class of
affluent educated people.
9Employment and Unemployment
- Cautiously Optimistic Forecasts
- Technology will continue to spur economic growth
and new jobs. - Economic growth may depend on whether we have a
suitably trained workforce. - The demand for professionals - teachers and
engineers is likely to rise. - Painful periods of adjustment may be in store for
many factory workers, clerical workers, and other
semiskilled and unskilled laborers
10Employment and Unemployment
- Will we need a New Economy?
- Do governments have an obligation to provide
permanent public assistance to the chronically
unemployed? - Should large companies be required to give
several months notice to workers whose jobs are
being eliminated? Should they be required to
retrain workers for other jobs?
11Employment and Unemployment
- Will we need a New Economy?
- Should large companies be required to file
employment impact statements before replacing
people with machines in the same way theyre
required to file environmental impact statements
before implementing policies that might harm the
environment? - If a worker is replaced by a robot, should the
worker receive a share of the robots earnings
through stocks or profit sharing?
12Education in the Information Age
- The American educational system was developed
more than a century ago to teach students the
basic facts and survival skills they would need
for jobs in industry and agriculture. It is known
as a factory model because it assumes - All students learn the same way and that all
students should learn the same things. - The teachers job is to pour facts into
students, occasionally checking the level of
knowledge in each student. - Students are expected to work individually,
absorb facts, and spend most of their time
sitting quietly in straight rows.
13Education in the Information Age
- How should education provide for students in the
information age?
- Technological familiarity
- Literacy
- Mathematics
- Culture
- Communication
- Learning how to learn
14Computers Go to School
Computers Go to School
Students can prepare for standardized tests
usingInside the SAT and ACT.16
Students in this class build LEGO robots and
write LOGO programs to control them.
15Computers Go to School
Computer-aided instruction (CAI)
- CAI software combines tutorial material with
drill-and-practice questions in an interactive
format that provides instant student feedback. - CAI is one of the most common types of courseware
because it is relatively easy and inexpensive to
produce and it can be easily combined with more
traditional educational techniques.
16Computers Go to School
Programming Tools
- Programming tools such as LOGO, Pascal, and Basic
allow young students to take a more active role
programming the computer.
17Computers Go to School
Simulations and Games
- Allow students to explore artificial
environments, whether imaginary or based on
reality. - Educational simulations are metaphors designed to
focus student attention on the most important
concepts.
Star Wars Droid works is a simulated robot
factory.
18Computers Go to School
Distance Education
- Distance education uses technology to extend the
educational process beyond the walls of the
school.
Asia Quest allowed students to communicate with a
team of scientists and explorers.
19Computers at School Midterm Grades
- A number of independent studies in the 90s
confirm that information technology can improve
education. Some of the findings are - Students improve problem-solving skills, outscore
classmates, and learn more rapidly in a variety
of subject areas and situations when using
technology as compared to conventional methods of
study. - Students find computer-based instruction to be
more motivational, less intimidating, and easier
to persist with than traditional instruction.
Independent research studies in the 1990s
confirm that information technology can improve
education.
20Computers at School Midterm Grades
- Well-designed interactive multimedia systems can
encourage active processing and higher order
thinking. - Students who create interactive multimedia
reports often learn better than those who learn
with more traditional methods. - Students can become more productive, more fluid
writers with computers. - Computers can help students master the basic
skills needed to participate and succeed in the
workforce. - Positive changes occur gradually as teachers gain
experience with the technology. - Technology can facilitate educational reform.
21Computers at School Midterm Grades
- Other findings temper - and sometimes contradict
- these positive conclusions. Researchers have
also found that - If the only thing that changes is the delivery
medium (from traditional media to computer
media), the advantages of technology are smallor
nonexistent. - Kids and teachers forget advanced computer skills
if they dont use them. - Students have unequal access to technology
economically disadvantaged students have less
computer access at school and at home. - Technology doesnt reduce teacher workloads if
anything, it seems to make their jobs harder (of
course, many teachers welcome the extra work
because they believe it brings results). - Theres a gender gap that typically puts the
computer room in the boys domain the gap can be
reduced by stressing computer activities that
involve collaboration.
22Computers at School Midterm Grades
- Many of the outcomes of technology-based
education dont show up with traditional
educational assessment methods. - Sending students to a computer lab for 30 minutes
a week has little or no value. Computers are
more effective when they are in classrooms where
students can use them regularly. - Younger students may be better served by art,
music, and shop classes than by computer classes.
Unfortunately, these important parts of the
curriculum are often eliminated to make room for
computers.
23The Classroom of Tomorrow
The Classroom of Tomorrow
- After more than a decade of research, ACOTs
research demonstrated that the introduction of
technology into classrooms can significantly
increase the potential for learning, especially
when it is used to support collaboration,
information access, and the expressions and
representation of students thoughts and ideas.
Research suggests that technology can have a
positive impact on education if it is part of a
program that includes teacher training, ongoing
support, and radical restructuring of the
traditional factory model curriculum.

- A smart card looks like a standard credit card
but instead of a magnetic strip, it contains an
embedded microprocessor and memory.

26Computers Come Home
- Home Entertainment Redefined
- Regardless of how people say they use home
computers, surveys suggest that many people use
them mostly to play games.
- Education and Information
- Home computer users use CD-ROMs to help with all
kinds of tasks, including locating streets in
far-off cities, planning wilderness treks, and
learning to play the guitar.
