Educational technology refers to the use of technology to improve learning and involves software, hardware, and internet applications. It has its origins in human prehistory and has evolved over time from the use of mechanical calculators in the 19th century to modern tools like smartphones, games, and educational software. Today, educational technology incorporates a wide variety of digital tools in classrooms, including interactive whiteboards, laptops, tablets, and online resources.

1. WHAT IS EDUCATIONAL
TECHNOLOGY?
 It is the study and ethical practice of facilitating e-learning, which is
the learning and improving performance by creating, using and
managing appropriate technological processes and resources.
 Educational technology includes software, hardware, as well as
Internet applications, such as wikis and blogs, and activities.
 Some modern tools include overhead projectors, laptop computers,
and calculators. Newer tools such as "smartphones" and games (both
online and offline) are beginning to draw serious attention for their
learning potential.

2. EDUCATIONAL TECHNOLOGY
 The origin of the term “ Educational technology”, can be traced
back to the time of human prehistory.
 19th century
 20th century
 Mid 20th century
 21st century
 Ed Tech today

3.  Mechanical calculators
 They became commercially successful in 1851.
 It was the first “programmable” machine.
 It used punched cards (binary instruction) to automate weaving loom
 It was powered by steam.
 These punched cards were a staple of early and modern computer
programming.

19TH CENTURY

4.  First Generation Electronic Computer systems used Vacuum Tubes
(1930)
 Vacuum tubes are glass tubes with circuits inside, they have no air
inside of them, which protects the circuitry. They used punch cards to
input and externally store data. They had up to 4k of memory.
20TH CENTURY

5. 20TH CENTURY
 ENIAC (Electronic Numerical Integrator And Computer) was
announced in 1946. It was the first electronic general-purpose
computer. It was capable of being reprogrammed to solve a full
range of computing problems. It was designed to calculate artillery
firing tables for the United States Army's Ballistic Research
Laboratory.

6. MID 20TH CENTURY
 FIRST GENERATION:
UNIVAC – 1951.
 Computers used vacuum tubes for circuitry and magnetic drums for memory.
 They were enormous, taking up entire rooms.
 They were very expensive to operate and used a great deal of electricity.
 1st generation computers could only solve one problem at a time
 Input was based on punched cards and paper tape, and output was displayed on
printouts.
 SECOND GENERATION:
 Almost all computers were made with transistors.
 The transistor was far superior to the vacuum tube.
 Computers became smaller, faster, cheaper, more energy-efficient and more
reliable.
 High-level programming languages were also being developed at this time
(COBOL and FORTRAN.)

7. MID 20TH CENTURY
• THIRD GENERATION:
 3rd Generation Computers used integrated Circuits which are
transistors, resistors, and capacitors integrated together into a single “chip” called
semiconductor.
 Users interacted with computers through keyboards and monitors.
 Different applications could be run at one time.
 Computers became accessible to a mass audience.
 They were smaller and cheaper.
 FOURTH GENERATION: MICROCOMPUTER REVOLUTION
BEGINS.
 Thousands of integrated circuits were built onto a single silicon chip. (microchips)
 In 1981 IBM introduced its first computer for the home user.
 Small computers became more powerful, they could be linked together to form
networks, which eventually led to the development of the Internet.

8. 21ST CENTURY
 The goal of fifth-generation computing is to develop devices that respond to
natural language input and are capable of learning and self-organization
 The internet expands faster. It becomes the world's largest database of
information.
 It becomes an invaluable resource for educators.
 Search engines (Google and Yahoo) develop new ways to find information.
 Voice recognition slowly enters the computing mainstream.
 Some computers incorporate TV input.
 Educational software becomes more useful and interesting to students.
 CD-ROM and DVD drives let educators store large graphic and video and sound
files for educational applications.

9. ED TECH TODAY!
 Four out of five students own a laptops, others use desktop PC’S and tablets.
 Teachers incorporate into their classrooms:
 Interactive whiteboards
 Smartboards
 CD ROMS
 DVD’S
 Blogs
 mobile platforms
 online games
 softwares
 instant messaging
