WHAT IS EDUCATIONALTECHNOLOGY? It is the study and ethical practice of facilitating e-learning, which isthe learning and improving performance by creating, using andmanaging appropriate technological processes and resources. Educational technology includes software, hardware, as well asInternet 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 (bothonline and offline) are beginning to draw serious attention for theirlearning potential.
EDUCATIONAL TECHNOLOGY The origin of the term “ Educational technology”, can be tracedback to the time of human prehistory. 19th century 20th century Mid 20th century 21st century Ed Tech today
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 computerprogramming. http://www.youtube.com/watch?v=f1Zzj9ZBYmQ http://www.youtube.com/watch?v=lwozgRPLVC819TH CENTURY
First Generation Electronic Computer systems used Vacuum Tubes(1930) Vacuum tubes are glass tubes with circuits inside, they have no airinside of them, which protects the circuitry. They used punch cards toinput and externally store data. They had up to 4k of memory.20TH CENTURY
20TH CENTURY ENIAC (Electronic Numerical Integrator And Computer) wasannounced in 1946. It was the first electronic general-purposecomputer. It was capable of being reprogrammed to solve a fullrange of computing problems. It was designed to calculate artilleryfiring tables for the United States Armys Ballistic ResearchLaboratory.
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 onprintouts. 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 morereliable. High-level programming languages were also being developed at this time(COBOL and FORTRAN.)
MID 20TH CENTURY• THIRD GENERATION: 3rd Generation Computers used integrated Circuits which aretransistors, resistors, and capacitors integrated together into a single “chip” calledsemiconductor. 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 REVOLUTIONBEGINS. 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 formnetworks, which eventually led to the development of the Internet.
21ST CENTURY The goal of fifth-generation computing is to develop devices that respond tonatural language input and are capable of learning and self-organization The internet expands faster. It becomes the worlds largest database ofinformation. 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 soundfiles for educational applications.
