2. When did the computing history
begin?
• It began approximately in 3000 BC. People
from Mesopotamia invented the abacus,
which is still used nowadays to count and
make quick calculations.

3. When did the computing history
begin?
• During the second half of the 17th century,
the French mathematician, inventor, writer
and physician Blaise Pascal invented the first
mechanical calculator. In order to solve maths
equations, the “Pascaline” used cogs and
gears.

4. The computing history and education
• Centuries later,
between 1943 and 1956
in the US, the first
vacuum tube-based
computers were
developed; universities
helped in computer
development effort;
technology used in war
effort.
• They used punch cards
to input and externally
stored data. It required
a compilar and it was
up to 4 K of memory.

5. The computing history and education
The first electronical digital
computer
• It was also used during the
WWII, so as to make
ballistic firing tables for the
US Department.
• The Electronical Numerical
Integrator and Calculator
1956 IBM 350 RAMAC
• It was developed by Bell
Labs. It used transistors; it
contained programming
computer languages, such
as FORTRAN and COBOL. It
was up to 32 K of memory.

6. Technology continues developing
Smaller computers
• In the 1960s, these new
computers used integrated
circuits. They were smaller,
cheaper and their processor
speed were increased. They
were up to 3 million bytes
of memory.
Microcomputers
• Microcomputers were
developed between the late
1960s and 1970. They were
processor chips. Altar and
Apple sold the first mini
computers which had bigger
storage space and memory,
as well as faster processing
speeds.

7. Education Technology
Computers at schools (1963)
• Money is invested on
schools; computers are
bought. However, the
mainframe and
minicomputers in use at this
time are using batch
processing methods that do
not fit well with the single
teacher-as-manager-of-
learning methods in use in
most schools.
Computers at universities (1965)
• High-level programming
languages such as Fortran
are being taught at
universities. School
vocational training
programs begin to include
computer maintenance.

8. Education Technology
From 1970 to 1990
• Computers started to be
used for personal uses; they
were known as PC. They
were rather expensive at
the beginning, but later on,
their prices began
decreasing. They could
stand alone or be
connected to other
computers as a network
system.
The revolution of the Internet
• In the late 1980s, the British
computer scientist Tim
Bernes-Lee developed the
HTML and the World Wide
Web (www) was born later.

9. Computers, the Internet and education
School and universities
• Little by little, more and
more computers were used
at schools and universities
for teaching purposes.
Then, when the Internet
was born, teachers had to
adapt to this new way of
transmission of information.
The number of Internet users keeps
increasing and increasing

10. New challenges for teachers
• According to M.D. Roblyer, education
technology is the combination of the
processes and tools involved in addressing
educational needs and problems with an
emphasis on applying the most current tools:
computers and their related technology.
• What are the implications for teaching?
