Introduction


Computers have been around for a long time In fact one of the first computers developed was the Chinese Abacus. The Abacus was developed many centuries ago and, is still in use in many parts of the world today. A computer is a electronic machine capable of solving problems by processing or manipulating information according to instructions that have been given to it.


Ironically though, the security and luxury that is to be enjoyed with computing has risks. Computers can also be used for tutorial purposes when prior information has not been learned. Computers can develop students’ graphing skills, assist with science projects, and increase problem solving abilities. For some years now, colleges have been jumping on the computer education bandwagon in an attempt to provide extra resources to help improve student learning. Research indicates that benefits can be gained by students who have access to computers and who participate in computer-based instruction. The Constructivist Theories of Learning offer a perspective on the use of computers as a productivity tool that can be understood(Forcier, 1). The application of the computer can make students more productive in the construction of their knowledge through problem solving.


Computer in Education

Today’s learners differ from learners of yesterday and one of the most dramatic changes currently facing students is the amount of information available to them and their greatly enhanced access to it. Today’s educated person is one who knows how to access information efficiently, evaluate it and apply it effectively. A computer is a tool that can give students a wider variety of educational experiences than has ever been offered before. Students are also increasing their productivity by developing sophisticated skills in the creation, access and manipulation and transmission of information in order to respond to an assignment or solve a problem, arranging information in more useful ways, and organizing and sharing information.


Why should students learn to use computers?


Expectations for computer literacy in the workplace are increasing rapidly. Many jobs demand computer literacy. Graduates who have computer skills are attractive job candidates. Students who are familiar with technology can make wise choices about when and how to use it or not use it.


In a society where global electronic communication is a daily occurrence for millions, skill in the use of information technology is rapidly becoming a basic requirement for success in the worlds of scholarship or work. There is no academic field today without at least part of the discourse within its community of scholars occurring electronically. Companies are listing computer skills as a prerequisite for job placement. These skills are no longer optional or desired, but mandatory in more and more firms, and have an immediate effect on a students employment.


Learning aide


Computers can also be used for tutorial purposes when prior information has not been learned. Computers can develop students’ graphing skills, assist with science projects, and increase problem solving abilities.


Accurarcy


Among other advantages of using computers for college students are in terms of its accuracy. For example, computers are bmore accurate than people can be. Computers remember one’s work (storage on a floppy disk) exactly as the user typed it by making a master copy of the document. When students need to change their letter they can have the computer recall or reload the master. This saves them a lot of time since they dont have to retype the letter or document.


Time Saving


By using computer, it saves time by automating repetitive tasks such as typing several hundred form letters. A computer can print these letters in a matter of hours. It would take a person several days to accomplish the same task. While the letters are printing students would have time to accomplish other duties such as going to classes, or joining co-curriculum activities. Computers dont get bored like people do. This makes them ideal for accuracy when they are assigned repetitive tasks. Once a computer is told how to do something, it can do that task indefinitely without making numerous mistakes.


Learning Advantages available through computer technology


Computer technology can greatly expand the learning options available to students and teachers in several categories. Two of the main categories are mentioned below


i. Immediate feedback.


Online exercises can offer students immediate confirmation of correct answers, prompts to aid recall, correction of errors. There are also software available int the market that makes it possible for students to receive immediate feedback; this is tremendously helpful as a learning tool.Students can take quizzes or solve problems on-line and have them graded automatically and quickly. Students can ask questions of instructors or classmates between class sessions and receive timely answers.This works best, of course, for testing mastery of simple factual content--questions that have only one correct answer. But programs are being developed that offer prompts and hints based on students incorrect answers.


ii. Repetition.


Most of the students are sensitive to the fact that different they learn in different ways. Computers present students with numerous ways to capture and save material so a student can access it when the student is ready to learn. This includes the fast-growing body of materials available on the web--a cyber-library.


Conclusion


About every aspect of our life is influenced by the personal computer. When we go to the grocery store, bank, or gas station, our purchases are controlled by personal computers. Over the last few years computers have become so commonplace that we find they have invaded the education perspective. Even though computers seem to be commonplace, the majority of people dont realize the impact to their lives. Once they start understanding how much computers control their every day routine they can develop a fear of these devices. From a review of relevant literature, one can conclude that there is a perceived benefit to such instruction although research has been inconclusive. What is clear, however, is that computer-based instruction has a tremendous impact on student learning motivation.
