In scientists and engineers up to the early 1970s

In education, ICT has a long history. Technology first used
in education a long time ago. But since it’s came to peoples acknowledgement,
technology first use in education in 1600s.

1. The Slide Rule: The first educational technology known as Slide Rule was first
introduced in 1654 by Robert Bissaker. The instrument was designed for use by
scientists and engineers up to the early 1970s till modern calculator was
invented. The Slide Rule was eventually used in the classroom for mathematics
and was a replacement to what we know today as electronic and graphing

2. The Magic Lantern: The magic lantern was first
introduced in 1646. Although the device was used in homes and theaters, magic
lanterns were used in the classroom to improve learning and student engagement.
The photographic slides were inserted one at a time for viewing of specific
images or subject matter.  Those who were proficient at using a magic
lantern could rapidly change the slides to make it appear as if the image was
moving. It was used as one kind of projection machine now used in modern


3. Slates and Chalk: It was in 1800s when technology
first introduced education with slates and chalks. Slates were
small kind of boards that were written on using a piece of chalk. Students used
slates in place of pen and paper, even though slates were not very useful for
longer work and could only be used to solve short equations.  Then they
were erased so they could be used to solve a new equation. So there was no scope
of saving.  After with all of those
limitations slates and chalk was revolutionary to education. In that time paper
was not easy to access. So this invention kept quite a good impact on education
that time.

4. Blackboards: Blackboards were made of slate that
was surrounded by a wooden border to prevent the slate from breaking. 
Slate was the material of choice due to its broad availability throughout the
world during the 19th century. Even it is been using in our county
now in most of our schools.   In recent years, it was determined that chalk
dust posed potential health risks which is one of the reasons they were
gradually replaced by the whiteboard as we know it today.

5. The Calculating Engine: In 1822, Charles
Babbage first introduced a calculating engine which led to modern day digital
computing.  The engine was capable of compute simple mathematics. Charles
Babbage is known as the “Father of Modern Digital Computing” as we know digital
computers in today’s classrooms.

6. The Typewriter: In 1873 Christopher L. Sholes first
introduced the typewriter which also debuted the QWERTY keyboard which is still
used on modern day devices and computers. Typewriter was used to typing books
and other educational materials. It brought a revolution to printing section,
one of the most important element for education.

7. The Film Projector: By 1925, the film projector was
making its way into classroom environments.  The projector displayed still
images from a film strip accompanied by an audio recording.  The images
had to be manually changed as you advanced through the film strip.  This
type of technology remained in the classroom until the early 1980s and was used
to study a particular topic or timeline of events. After that more modern,
overhead projector was invented that we use in our modern classroom now a days.

8. The Photocopier: The photocopier was invented at the
last year of 1950s by Xerox. It was widely used for copying books and other
educational materials. This machine was one of the most important invention for
modern education. From then to now there is no alternative to photocopier



9. The handheld Calculator: The
handheld calculator was invented in 1970s. It is a revolution to modern
mathematics. Though it was concerned that it will decrease the basic sides of
mathematics like longer division or multiplications. But it was a great help to
classroom education. It made mathematical procedure faster.

10. The Personal Computer: In the early 1980s
International business machine (IBM) introduced first personal computer.
Although computer was invented a long before that but it was not used widely.
After invention of personal computer it was possible to use widely. Internet
was not accessed by everyone that time, so PCs were used to typing and
calculating larger mathematics and equations.

11. The CD-ROM: The CD-ROM was brought to
educational environment in mid of 1980s. At that time storing data was not that
much easy. CD-ROM made it very easy. Students was able to store audio, video
even the whole encyclopedia in one compact disk. Though it is now less important
to us as we use flash drives but at that that time for carrying data and saving
data it was best.

12. The Internet: In the early-mid of 1990s, internet
was made available for public. It brought revolution to public life. Education
became more efficient with internet. In the first periods, it wasn’t that much
speedy as like todays. That time internet just could use to transfer smaller
files. Now it’s possible to transfer almost every kinds of files. With the help
of internet it’s possible to learn anything even without help of any teacher.


13. The Interactive Whiteboard: The interactive whiteboard was invented just
before the 21st century. It gradually replacing other whiteboards
and blackboards. One interactive whiteboard needed a white screen, an overhead
projector and a computer. In this type of board it’s possible to present
anything graphically. It is a miracle to classroom education.

14. Virtual Reality: latest include in modern
education is virtual reality. Many educators have been improving their
classroom learning experience using virtual or augmented reality.  Modern
devices such as Google Cardboard VR allow students to study locations and
objects in 3D in addition to exploring current events.
