A Link to the Future
Where is
Education Going
with Technology?
Emerging Technologies
• Networking
• Visualization
• Human-to-Computer
Interfaces
• Artificial Intelligence
and Intelligent CAI
• Innovative Equipment
Networking

•
Increased Capability and Use of Home Systems
Higher-speed Connections
Rewiring of Educational Facilities
Wireless Communication
Collaboration at different physical sites
Changing definitions of distance education
Innovative Equipment
• Wearable systems: small displays that fit over one
eye or glasses that provide a “heads-up” similar to
military fighter pilots, hip pocket CPU and storage,
data gloves, voice recognition and audio feedback
• E-books (electronic books): children could connect
to libraries from anywhere and the downloaded text
could delete itself at the end of the loan period
• Handheld devices for GPS (global positioning
systems) on clothing could locate a missing child
Visualization
• Virtual environments & field trips
• Use of avatars: An Avatar is any
Web3D object, humanoid or not,
that is designed to represent a visitor
to Web3D multiuser environment.
• Models as learning data
• Freedom for handicapped learners:
can practice skills in private,
controlled environments
Artificial Intelligence and Intelligent
CAI
• Expert systems: computerize human expertise into a
narrow field of knowledge, then acts like an advisor
to offer suggestions to aid user’s decision making
• Coaches: used in word-processing & spreadsheets
that step you through developing a document; used
in tutorials, simulations, and problem-solving
packages
• Student performance feedback: integrate the
accumulated knowledge of a subject area for testing
Artificial Intelligence and Intelligent
CAI
• Intelligent agents: do various jobs for students and
learn by observing a user’s actions and noting
patterns of behavior to provide articles when
searching databases and archives
• ICAI: intelligent computer assisted instruction
monitors and creates a profile for each student and
tailors instruction to it
• Personal tutoring systems and critical-thinking
skills: helps student develop their own expert
systems as a learning experience
Human-to-Computer Interfaces
• Voice/audio and Voice
recognition
• Physical Log-in using
fingerprints or eye retina
scans
• Email is more visual and
voice-activated
Visions of Technology’s Role in
Restructuring Education
• Replacing teachers versus changing teacher roles:
technology tools will empower them to teach better and
use their time more productively
• The role of distance education: bringing about radical
restructuring of learning opportunities at all levels
• Knowledge web for distributed online conferences
• Virtual communities to complement classroom activities
• Sensory immersion in virtual reality environments
Teachers’ Vision
• Must have a vision of what they are working toward
in their classroom and school
• Recognize the kind of infrastructure necessary to
bring about their vision
• Be active in building growth and change
• Must adopt an outlook that their pre-service
preparation is only a first step in what must be a
life-long exploration of ways to use technology and
other resources to improve education
Future Skills for Teachers
• Keep up with change
• Learn to adopt effective strategies such
as reading technical and educational
publications
• Attend training sessions
• Peruse Internet web sites for new ideas
• Keep as current as possible on the new
and anticipated technologies
Summary
• Computer hardware development will continue to
outstrip software’s ability to take advantage of them:
computer processors are faster, smaller and more
capable, but operating systems can’t handle it as fast
• Education’s response to new technologies is slower
than the military and business...it is a long, slow
process to integrate technology into instruction
• Lack of access means lack of educational
opportunities for many families in this nation.
