4. THE PAST
from fingers and toes to what everyone knows

5. Hey there! I’m glad you could all join me.
Cell phones, laptops, PDAs, iPods and
digital cameras were not always considered
everyday items. Let’s take a look at life B.G.
(before Google)!

6. 10: The basis of our number system
 Primitive humans
found counting
necessary, and fingers
provided a natural tool,
creating a number
system based on 10.
 As time passed, rocks,
notches on wood, etc.
were used to calculate
and record larger
numbers.

7. Manipulation of Data
 The abacus was the first
instrument known that
allowed users to
manipulate data rather
than just record it.
 It is believed that the
abacus originated in  Learn more about how

divide as well as add.
 The introduction of
binary arithmetic and
Boolean logic led to the
development of the
internal language of
today’s digital
computers.

9. Generations of Computers
1st Generation 2nd Generation
 Early 1950’s  Mid-1950’s
 Vacuum tubes  Transistor

10. Generations of Computers
3rd Generation 4th Generation
 Early 1960’s  1970 – Mid 1990’s
 Integrated Circuits  Microprocessor

11. THE PRESENT
where computing is now

12. Wow! That was cool. Computers sure have
come a long way, but there is still more. Let’s
take a look at 5th generation computers and see
how the latest developments have changed
today’s world - especially in the field of
education.

13. 5th Generation
Computers
“The fifth
generation of
computers offers
the development
of artificial
intelligence,
computers based
on logical
inference and
parallel
processing, and
radical changes in
the Internet” (Sharp
15).

14. Modern Features
 Today’s computers can
carry out thousands of
operations
simultaneously.
 They feature:
 Voice recognition
 Natural and foreign
language translation
 Touch screens
 Handwriting recognition
with stylus input devices
 In what ways do these
features enhance
education?

15. Artificial Intelligence
 AI is a “computer science
field that tries to improve
computers by endowing
them with some of the
characteristics associated
with human intelligence,
such as the capability to
understand natural
language and to reason
under conditions of
uncertainty” (Sharp 14).

sounds a little sci-fi-ish,
but the fact is, you find

17. Internet
 The Internet is a
worldwide computer
networking system.
 It is used to:
 teach distance courses;
 communicate via voice,
data, and video
conferencing;
 research;
 work from home;
 house virtual
environments; etc.

18. The Web is Transforming…
 The Internet no
longer has the sole
purpose of providing
information.
 It has become the
read – write web
where users want to
be heard themselves
as much as they
want to see what
others are saying.

19. Hypertext & Hypermedia
 Research has shown that  It has been proposed that

 Students have the ability to
personalize learning by
exploring topics that
interest them in more
depth.
 Students can use hypertext
to scaffold their reading,
and can potentially read e-
texts at a higher level
because they can use
hypertext to define
unknown words.

22. Technology is still evolving. Come with me to
take a peek at what the future may bring. Where
will you fit in? Will you embrace the latest
technological advancements or do you prefer the
status quo? How will you weave technology into
your philosophy of education?

23. What will the future hold?
 There are already many
predictions about where
the web will go next.
 How do we prepare
students to work in an
environment that doesn’t
yet exist?
 How will teacher training
be effected?
 Will life-long learning
become a must instead of
a lofty goal?

25. Putting it in Perspective

26. EDUCATIONAL TECHNOLOGY
How changes in technology have revolutionized education

27. What does all of this mean? Bottom line –
educational technology is constantly changing, and
bringing about new and exciting ways to help
students of all ages learn! Let’s take a quick look at
how technology has been used in the classroom.

28. Educational Technology
 While definitions vary, the Association for
Educational Communications and Technology
(AECT), states "Educational technology is the
theory and practice of design, development,
utilization, management, and evaluation of
processes and resources for learning."

29. Advantages of Educational Technology
 Papers can be easily stored, revised, and
shared.
 The Internet can be a valuable library and
research resource.
 Differentiated instruction for various
learning styles can be provided.
 Multimedia presentations that include art
and music can be created.
 Software programs can be used to assist
students or create newsletters and other
documents.
 Web sites and software can assist with
teacher and administrator planning.
 Computers can help with institutional
organization and inventory.

30. Brief History of Computers in Education
 Computers were first used in
education in the fields of
science, math and
engineering.
 The first techniques included:
 A behavioral approach to
tutoring – programmed
instruction, where info was
taught in small, sequential bits
at the learners own pace with
automatic feedback.
 Computer based simulations
 The first flight simulator was
created in 1950 at MIT.
 Teaching programming
languages such as BASIC
 Due to a lack of software Project Whirlwind: 1st Flight Simulator
designed for Navy training by MIT in 1950.

31. Microcomputer Brings Mega Changes
 In 1977 the
microcomputer shifted
the focus from
mainframes to desktop
computers
 An educational software
market emerged to meet
the needs of classroom
teachers.
 Soon, computers
networks were formed
through intranets and
internets.

32. Today
 The internet is a powerful
educational tool.
 Leading professional
groups and state
departments of education  The National Educational
have developed Technology Standards
educational technology project is ongoing.
standards for teachers,
 The goal is to facilitate
students, and schools. improvement in U.S.
 Accreditation standards for schools by implementing
teachers require technology in instruction,
technology training. activities, and assessment.

33. Debate
 Over the years, there has
been a debate on the best
way to use technology to
enhance learning.
 These debates often stem
from educational
philosophies that are
teacher-directed or
constructivist based.
 Research has not
provided conclusive
evidence to support one
side or the other.
 Why do you think this is?

34. Educational Philosophies & Technology
Teacher-directed Approach Technology Applications
 Based on worksheets &  Programmed
textbooks
 Curriculum is fixed instruction programs
 Teacher transmits knowledge such as Math Blaster
 Instruction is didactic  Drill-and-practice and

36. REVIEW &ASSESS
What did you learn?

37. Time to pray – just kidding! You are about to take a
quiz to assess what you have learned. But wait – you
can relax and smile, because it is open webquest!
The purpose is to see how the traditional quiz can be
adapted to be taken using a computer. Did you like
getting immediate feedback? What did you think
are the positive and negatives of this type of
assessment? How else might you use technology to
assess your students? What educational philosophy
would this type of quiz fall under?

38. Review
 McGraw-Hill online
has summaries to
review the information:
 History of Computers
 Educational Milestones
& Standards

have developed as technology
advances?
 How do you see using technology in
your classroom?
 What do students need to know
about technology?
 What do you want to learn more
about?
