The Benefits of Computers in the Classroom for Students

The Benefits of Computers in the Classroom for Students


Computers have changed the way society functions. Future generations will need to compete with the growing trends of a technologically-driven society that relies on computers to perform daily tasks. The classroom is a good starting point for people to learn how to use these complex machines. If students learn word processing skills and how to navigate computers and the Internet early on, they will be prepared later in life to utilize computers for more complex assignments. Computers grant access to the Internet, which hosts academic research and offers educational support. Historical records and social organizations are only a click away, providing a wealth of information for studying history and social studies. Students and teachers are now able to communicate with educators and other students anywhere in the world easily and instantly. This new phenomenon opens up opportunities for collaboration that did not previously exist. There are also many resources and communities online that are available to help students develop and improve mathematical and scientific understanding. Even though computers are extremely beneficial to the educational process there are some negative aspects that present themselves. Students have access to greater distractions during research or study time, in the forms of games and social networking websites. There is also the risk of students interacting with potentially dangerous, anonymous individuals. Therefore, it becomes vitally important for teachers and school faculty to monitor computer use to ensure they are being used safely and for the right purposes.

Uses of Computers in Schools

Uses of Computers in Schools


Computers are an integral part of schools now instead of being supplemental features. They can be used in a variety of ways to augment knowledge and application.

Research

·         This is the most common use for students in grades 4 through 12. When students have to write research papers on a specific topic, the computer provides the most easily accessible sources.

Data Entry

·         Basic keyboarding and word processing skills are taught on the computer. Knowledge of these is essential for school, college and career.

Intervention

·         Computers are also being used to help learning disabled students. There are many interactive and tutorial programs online or available as software that help the challenged student with reading, math or other areas of weakness.

Virtual

·         The use of computers has changed the face of distance education. Students can now be logged in at the same time, post assignments, and talk to each other on message boards while working on their college degrees.

Teacher Resource


·         The Internet provides a wealth of resources for teachers like lesson plans, pre-made tests, study guides, worksheets, and other activities that only have to be downloaded and printed. There are also grade book programs and class record-keeping templates that are time-savers.

All the mobile phones that mattered from the first Nokia handset right up to the iPhone 3G
A LOT can happen in 40 years. But when it comes to technology, 40-years is like going back to the days of Moses or the Roman Empire. Case in point: the mobile phone –– and, more recently, the rise of mobile internet communications, social networks and super-fast internet. But what were the phones that made it happen; who were the pioneering brands that made today's handsets possible; and which phone, out of the thousands launched since the 1980s, was the most important? Answer: quite a few.
But first: a history lesson. 
The world’s first mobile phone call was made on April 3, 1973, when Martin Cooper, a senior engineer at Motorola, called a rival telecommunications company and informed them he was speaking via a mobile phone. The phone Cooper used, if you could call it that, weighed a staggering 1.1kg and measured in at 228.6x127x44.4mm. With this prototype device, you got 30 minutes of talk-time and it took around 10 hours to charge.

In 1983, Motorola released its first commercial mobile phone, known as the Motorola DynaTAC 8000X. The handset offered 30 minutes of talk-time, six hours standby, and could store 30 phone numbers. It also cost £2639 ($3995).
In the very early days of the mobile space handsets weren’t designed with consumers in mind. You’d need a couple of thousand pounds to get hold of one, and even then performance wasn’t great. Back then, mobile phones were designed with the likes of Gordon Gecko in mind, businessmen-types that drove big Jags and flew Concord. Not your average Joe.
Mobile Phone FACTS
Here is a selection of facts, courtesy of Fact Slides, about mobile phones that show just how much the world has changed since the early days of mobile communication:
§  In 1983, the first mobile phones went on sale in the U.S. at almost $4,000 each.
§  Over 250 million Nokia 1100 devices were sold, making it the bestselling electrical gadget in history.
§  More People In The World Have Mobile Phones Than Toilets.
§  So many Facebook photos and videos are uploaded via mobile that it takes up 27% of upstream web traffic.
§  The technology behind smartphones relies on up to 250,000 separate patents.
§  The average person unlocks his or her smartphone 110 times each day.
Even at the start of the 1990s this was still the case despite Nokia and NEC entering the fray. Nokia’s first 'handheld' mobile phone, the Mobira Cityman 900, launched in 1989 and weighed just 800g – a huge improvement over 1982’s 9.8kg Mobira Senator model. 
1990 to 1995 represented an upward swerve in design and portability, with mobile devices gradually starting to appear in the hands of average consumers for the first time. By the late-1990s, mobile devices were fast becoming the norm thanks to the following handsets…

The BlackBerry 850 was the first handset released under the BlackBerry brand. Ten years later, RIM would be crowned the fastest growing company on the planet. And we all know what happened post-2010.


A BRIEF COMPUTER HISTORY

A BRIEF COMPUTER HISTORY
The computer as we know it today had its beginning with a 19th century English mathematics professor name Charles Babbage.

He designed the Analytical Engine and it was this design that the basic framework of the computers of today are based on.


Generally speaking, computers can be classified into three generations. Each generation lasted for a certain period of time,and each gave us either a new and improved computer or an improvement to the existing computer.

First generation: 1937 – 1946 - In 1937 the first electronic digital computer was built by Dr. John V. Atanasoff and Clifford Berry. It was called the Atanasoff-Berry Computer (ABC). In 1943 an electronic computer name the Colossus was built for the military. Other developments continued until in 1946 the first general– purpose digital computer, the Electronic Numerical Integrator and Computer (ENIAC) was built. It is said that this computer weighed 30 tons, and had 18,000 vacuum tubes which was used for processing. When this computer was turned on for the first time lights dim in sections of Philadelphia. Computers of this generation could only perform single task, and they had no operating system.

Second generation: 1947 – 1962 - This generation of computers used transistors instead of vacuum tubes which were more reliable. In 1951 the first computer for commercial use was introduced to the public; the Universal Automatic Computer (UNIVAC 1). In 1953 the International Business Machine (IBM) 650 and 700 series computers made their mark in the computer world. During this generation of computers over 100 computer programming languages were developed, computers had memory and operating systems. Storage media such as tape and disk were in use also were printers for output.


Third generation: 1963 - present - The invention of integrated circuit brought us the third generation of computers. With this invention computers became smaller, more powerful more reliable and they are able to run many different programs at the same time. In1980 Microsoft Disk Operating System (MS-Dos) was born and in 1981 IBM introduced the personal computer (PC) for home and office use. Three years later Apple gave us the Macintosh computer with its icon driven interface and the 90s gave us Windows operating system.



As a result of the various improvements to the development of the computer we have seen the computer being used in all areas of life. It is a very useful tool that will continue to experience new development as time passes.

School System Works in India

Details of how the school system works in India, including the type of education available…
According to the 2009 Right to Education Act, schooling is free and compulsory for all children from the ages of 6 to 14. However, improvements are slow being implemented and disadvantaged groups may still not have adequate access to education.
A high value is placed on education, as it ensures a stable future. All parents want their children to attend the best private English schools, but places are limited. The admission process is therefore highly competitive.
Most Indian schools have a strong focus on academic subjects, with little scope for creativity and few or no extra-curricular activities. Traditional schooling methods tend to emphasise rote learning and memorisation, rather than encouraging independent or creative thinking. There is a strong focus on examinations from an early age. This makes the atmosphere at Indian schools competitive.
Many expats prefer to send their children to international schools. Others choose a more progressive Indian school that is less traditional in its teaching style.
The Education System
The Indian education system is structured as follows:
  • Pre-school: Education at this level is not compulsory. The Montessori system is especially popular at the pre-school level
  • Private playschools: Catering for children between the ages of 18 months and three
  • Kindergarten: This is divided into lower kindergarten (for three- to four-year-olds) and upper kindergarten (for four- to five-year-olds)
  • Primary school: First to fifth standard/class/grade (for six- to ten-year-olds)
  • Middle school: Fifth to eighth standard/class/grade (for 11- to 14-year-olds)
  • Secondary school: Ninth and tenth standard/class/grade (for 14- to 16-year-olds)
  • Higher secondary or pre-university: 11th and 12th standard/class/grade (for 16- to 17-year-olds). This is when students choose an academic area on which to focus
  • Undergraduate: A BA is a three-year degree. Specialised courses such as medicine and engineering can be longer
  • Postgraduate: A one-year course
Types of Schools

  • Public/government schools: Most schools in India are funded and run by the government. However, the public education system faces serious challenges including a lack of adequate infrastructure, insufficient funding, a shortage of staff and scarce facilities
  • Private schools: Since many government schools do not provide adequate education, Indian parents aspire to send their children to a private school. Some expats choose to send their children to private Indian schools
  • International schools: There are international schools in all major cities. They are attended by expat and Indian children
  • National open schools: Provide education up to the higher secondary level for children whose schooling has been interrupted and have been unable to complete formal education
  • Special-needs schools: Provide non-formal education and vocational training to children with disabilities
