Computers and Teaching
"The speed with which technology has developed since the invention of the computer has been extraordinary and surprisingly sustained. For educators, the rapid and continuing introduction of new technology into education, has outpaced the ability of teachers and developers to evaluate it properly, " says Levy, (1997:1). And he continues, that as soon as teachers have become acquainted with one kind of software and hardware and have developed some ability to use it for educational purposes, "better" machines appear to displace it.
According to Ahmad et al (1985), computers bring to education what all new technical devices have brought about: skepticism and fear, or "euphoria followed by...show more content...
They'd better train students in computes skills in a specific area like IT , or they must consider computers as part of the class as the pencil, pen, chalk and blackboard. (Classe, 1998)
"In our schools, every classroom in America must be connected to the information superhighway with computers and good software and well–trained teachers" (Clinton, B: 1996, in Bush et al: 1997)
Teacher training has been supported by different sources, as mentioned by Cwiklik (1997). Federal funds have been used in programs such as the Technology Innovation Challenge Grant Program, which provides funds for schools developing projects that encourage the good use of technology in education. And the Technology Literacy Challenge Fund set up last year for state education agencies to distribute to school–technology initiatives.
Schools, districts or teachers' certified agencies also sustain programs to develop teacher training, such as the Community School District One in New York, the New York Public Schools with the "Project Smart", or the Olympia, WA, School district which devised the original "Generation Why." All mentioned by Cwiklik in Wall Street Journal (1997).
Teacher training is also left up to teachers who want to initiate participation by themselves, and enroll in some of the multiple courses offered by colleges all over the USA.
In any case, as Katie Hickox (1997) says, teacher training

When it was finished in 1950 it became the fastest computer in the world.17 It was built by the National Bureau of standards on the campus of UCLA. It was names the
National Bureau of Standards Western Automatic Computer or the SWAC. It could be said that the SWAC set the standards for computers for later up to present times.18 It was because the had all the same primary units. It had a storage device, a internal clock, an input output device, and arithmetic logic unit that consisting of a control and arithmetic unit. These computers were considered first generation computers (1942 – 1958). In 1948 John Bardeen, Walter Brattain, and William Schockley of Bell labs file for the firs patent on the transistor.19 This invention would foundation for second generation computers (1958 – 1964). Computers of the second generation were smaller(about the size of a piano now) and much more quicker because of the new inventions of its time. Computers used the much smaller transistor over the bulky vacuum tubes. Another invention which influenced second generation computers and every generation after it was the discovery of magnetic core memory. Now magnetic tapes and disks were used to store programs instead of being stored in the computer. This way the computer could be used for many operations without totally being reprogrammed or rewired to do another task. All you had to do was pop in another disk. The third generation(1964 – 1970) was when computers

The first devices that resemble modern computers date to the mid–20th century (around 1940 – 1945), although the computer concept and various machines similar to computers existed earlier. Early electronic computers were the size of a large room, consuming as much power as several hundred modern personal computers. Modern computers are based on tiny integrated circuits and are millions to billions of times more capable while occupying a fraction of the space. Today, simple computers may be made small enough to fit into a wristwatch and be powered from a watch battery. Personal computers in various forms are icons of the Information Age and are what most people think of as "a computer"; however, the most...show more content...
This effort was funded by ARPA (now DARPA), and the computer network that it produced was called the ARPANET. The technologies that made the Arpanet possible spread and evolved. In time, the network spread beyond academic and military institutions and became known as the Internet. The emergence of networking involved a redefinition of the nature and boundaries of the computer. Computer operating systems and applications were modified to include the ability to define and access the resources of other computers on the network, such as peripheral devices, stored information, and the like, as extensions of the resources of an individual computer. Initially these facilities were available primarily to people working in high–tech environments, but in the 1990s the spread of applications like e–mail and the World Wide Web, combined with the development of cheap, fast networking technologies like Ethernet and ADSL saw computer networking become almost ubiquitous. In fact, the number of computers that are networked is growing phenomenally. A very large proportion of personal computers regularly connect to the Internet to communicate and receive information. "Wireless" networking, often utilizing mobile phone networks, has meant networking is becoming increasingly ubiquitous even in mobile computing environments.

The first modern digital computers were developed in the 1940s for military purposes that arose during World War II. These computers filled entire rooms. They took hours to perform complex mathematical operations. In the 1970s, the first personal computers were sold. Fitting on a desktop, they were much faster and more powerful than the computers that had once filled large rooms. Computers were also affordable to individual consumers, making it possible for many people to use them for personal, business, and academic needs. By the mid–1990s, laptop computers capable of millions of calculations per second had been developed.

Internet is the network connecting all of these computers to each other. Some people are calling it the information highway. The network help computers to join together to communicate with us and for us. As we look to the future the changes to society will be as revolutionary as those of the Industrial Age and the Renaissance. Not only will people shop and conduct business through their computers, but they will also engage in every type of human activity, from reading to simply hanging out with friends. The increased level of communication made possible by computer networks will bring many benefits in the areas of business, education, and social interaction, producing sharing of knowledge and wealth and a worldwide cultural renewal. A few critics, however, are skeptical of the optimism of computer enthusiasts. They question whether the benefits of computer technology will outweigh the potential harms. One of the arguments is that technology has done nothing to help in our social problems. Since computers tend to decrease actual human contact, their use may weaken people's sense of community and increase existing social divisions.
One area in which the optimism of computer enthusiasts comes into immediate conflict with the skepticism of critics is education. Those who believe that computers will bring revolutionary changes to society say that schools should prepare children for that future with computer education. By giving

Children will feel lonely because they spent most of their time on computers instead of spending their time with their family."This increases their daily stress because if they are not talking with their parents it means they are not sharing their problem, which is why they are facing trouble."( Wisdia "computer affects", n.d.). Children should be with their parents instead of playing on computers because parents always advise and help their children. To conclude, computer games can affect on children in negative way, and change their behavior. Second, Internet affects on children in two negative ways. One obvious negative effect is login on sites that can damage children's life. "Sites encourage children to use the Internet for the production, manufacture, and distribution pornography" (ojp, "Internet" , May 2001). For example, login on sites that sell alcohol and drugs.

The first ever computer was invented in the 1820s by Charlse Babbage. However the first electronic digital computer were developed between 1940 and 1945 in the United States and in the United Kingdom. They were gigantic, originally the size of a large room, and also need to be supply a large amount of power source which is equivalent as several hundred modern personal computers. The history of computer hardware covers the developments from simple devices to aid calculation, to mechanical calculators, punched card data processing and on to modern stored program computers. The tools or mechanical tool used to help in calculation are called calculators while the machine operator that help in calculations is called computer. At first the...show more content...
UNIVAC 1 was created to process data like Herman Hollerith's tabulator over 50 years before, however UNIVAC 1 was then manufactured for other users and become the world's first large scale commercial computer. The key period of the evolution of modern electronic computer is in between the late 1930s and the early 1950s. Not all of them were invented by the mathematician or physician. Among those machines were pioneering computers put together by english academics notably Manchester/Ferrenti Mark 1, built at Manchester University by Frederic Williams and Thomas Kilburn. And the EDSAC, Electronic Delay Storage Automatic Calculator built by Maurice Wilkes at Cambridge University. The microelectronic revolution started when they were using the vacuum tubes it consume a lot of power supply. As a comparison the ENIAC used about 2000 times as much electricity as the modern laptop. Not just that, the modern term for a problem that holds up a computer program is a "bug". Popular legend has it that this word entered the vocabulary of computer programmers sometimes in the 1950s when moths, attracted by the glowing lights of vacuum tubes, flew inside machines and caused a short circuit. In order to create more advance computer, would have needed hundreds of thousands or even millions of tubes, which would have been

10–70 AD) built a mechanical theater which performed a play lasting 10 minutes and was operated by a complex system of ropes and drums that might be considered to be a means of deciding which parts of the mechanism performed which actions and when. This is the essence of programmability.
Around the end of the 10th century, the French monk Gerbert d 'Aurillac brought back from Spain the drawings of a machine invented by the Moors that answered either Yes or No to the questions it was asked. Again in the 13th century, the monks Albertus Magnus andRoger Bacon built talking androids without any further development (Albertus Magnus complained that he had wasted forty years of his life when Thomas Aquinas, terrified by his machine, destroyed it).
In 1642, the Renaissance saw the invention of the mechanical calculator, a device that could perform all four arithmetic operations without relying on human intelligence. The mechanical calculator was at the root of the development of computers in two separate ways. Initially, it was in trying to develop more powerful and more flexible calculators

Some surgical procedures are computer–guided. These types of surgeries mean that the patient has less downtime since the procedures are more straight–forward. Storing information using computers has changed the way in which the world works. The computer has helped the medical field as much as or more than other fields (Maddox, Amanda).
In every medical office there are various uses of computers. They contribute a lot to the hospital administration; all the administrative processes are kept in computers. Staff records, incoming and outgoing time of the staff, the holiday records of the staff, anything to do with the staff, are all examples of how computers are used in a medical office. If the doctor were to hand–write every little thing, to keep track of such things, it would be very difficult, but with computers, the task uses less time and the process is simplified. In most medical offices, accounting is also computerized; it helps you keep the daily records of the financial transactions. It also can reduce the chances of money related frauds because all the data is stored into a computer and can be used for future reference. Computers also help in recording the names and contact details of the doctors and associated people and also the patients. It is useful when it comes to recording the medical history of the patient, such as, previous treatments and tests, diagnosis and symptoms, surgeries, etc. Such information
