COMPUTER PERSPECTIVE


Computer is a programmer machine. The two principal characteristics of a computer are responds to a specific set of instructions in a well-defined manner. It also can execute a prerecorded list of instructions (a program). The advantages of using the computers especially for children can help them to be in control of their experience, to set their own pace, and to select the level of challenge with which they feel comfortable. Computers help children to use all of their senses to extract information. Computers fascinate kids and can draw their full attention, which often results in a deeper focus and concentration.
Computers enable children to learn through creating, just as they gain hands-on knowledge and understanding when they build forts, make up stories, and paint, increase their skills As they master computers, children build positive attitudes toward technology that will pay dividends for the rest of their lives. In the emotional skills by using a computer children develop self-confidence and self-esteem as they master computer skills and use the computer to make things happen. This also gives them a reason to smile! In the social skills in the classroom setting or in the home when their friends or parents are available, children often prefer working with one or two partners over working alone, which leads to the development of social skills.
The Computers make benefit for children with special needs, such as good educational software enables children to develop and practice a broad range skills. It can help them learn, for example, about letters, numbers, shapes, colors, and rhythm. Good software can also help children develop their understanding of cause and effect, higher order problem solving, procedural thinking, and creative expression. Today, the wide range of multimedia available for kids in India is really amazing. Computers have proven extremely beneficial to kids with certain speech, audio, and motor limitations. Kids with special needs can use alternative input and output devices (assistive technologies) to interact with computers and do things that they normally could not accomplish independently. They benefit especially from having access to an on-demand, patient tutor that allows them to work at their own pace. What they achieve through using a computer enhances their self-esteem and provides them with a greater sense of control and engagement with the world. The internet provides them with the best of knowledge for their treatments and they can be in touch with doctors or friends through the internet, in India or Abroad. Also, the internet can later help them earn their means of livelihood.
The disadvantages of using the Computers are very engaging and can exercise a strong "holding power" on children as well as adults. They really seem to mesmerize children. Since we do not yet understand the impact of this power, we need to monitor the amount of time a child spends before a computer. If the software is not age-appropriate, children are likely to become frustrated and associate a computer with failure. Kids with access to software that is not age appropriate may be exposed to such negative influences as violence, strong language, and over-stimulation from fast-action graphics. Frequent and prolonged computer sessions may pose physical health risks for children. The most frequently cited are visual strain, harmful effects of radiation, and posture and skeletal problems. In the case of normal usage and normal operating conditions, however, research has shown that computer monitors are safe and do not compromise the health of our eyes and that computer monitors emit little or no harmful radiation.
There are also disadvantages of using the computer. There are learners with low motivation or bad study habits may fall behind , without the routine structures of a traditional class, students may get lost or confused about course activities and deadlines , Students may feel isolated from the instructor and classmates , instructor may not always be available when students are studying or need help , slow Internet connections or older computers may make accessing course materials frustrating and managing computer files and online learning software can sometimes seem complex for students with beginner-level computer skills, also hands-on or lab work is difficult to simulate in a virtual classroom .
In the conclusion, there are many perspectives about using a computer. it can be advantages or disadvantages.
