Computer in Education
There is a great deal of interest in the use of computers in education. The educational use of computers is called Computer Assisted Instruction, or CAI. Many public schools in the United States have acquired computers and CAI programs to rum on them. School districts are establishing computer resource centers and special training programs to help teachers use computers. In addition, some colleges and universities are beginning to establish computer literacy requirements for graduation. In spite of all this interest in the use of computers in education, some educators and students still may be wondering if this expensive toy is really worth their time and, in some cases, money. The answer is a definite yes: The use of computers in education has important benefits for both students and teachers.
Computers enhance a student’s learning experience in many ways. First of all, the computer has the ability to accommodate individual differences in learning speed because the user (the student) is the one who controls the pace of the lessons. In addition, because a computer is nonjudgmental, the learner does not have to be afraid of reprisal or humiliation when making errors. For example, because computers can repeat information over and over, the user can ask for many repetitions of a lesson without fearing a judgmental response about his or her ability to learn. The beneficial effects of learning in a stress-free atmosphere are well documented. A third advantage of CAI is that computer can give a student immediate feedback. It can tell the student why she or he is wrong as soon as an error is made, and it can even provide an approach hint for figuring out the correct answer.
Not only do computers benefit students, they also make the teacher’s job easier. One advantage lies in the preparation of instructional materials. Schools and colleges can purchase educational computer programs that can be adapted to any learning situation. These systems, called “authoring systems,” are like skeletal lesson plans: The format of several exercises and tests is already planned out; all the teacher adds is the information he or she wants the students to learn (mathematical problems, vocabulary lists, and so forth). The authoring system automatically incorporates these teaching points into its preplanned format and then is ready to be used by several students for a long time. The system can also correct the students’ work and determine and record grades. In addition, the computer offers numerous advantages to teachers in managing their classrooms. A computer laboratory (a room having one computer for every two students) can free the teacher to meet individually with students while the rest of the class is occupied with computer lessons. Finally, computers can help teachers keep student records and chart student progress, thereby cutting down on time—consuming paperwork.”
With all of these advantages for both teachers and students, it is easy to see why there is so much interest in using computers in education. Of course, there are those who are skeptical and view computers as a passing fad. There are those also who simply are afraid of them. In time, however, computers will become as familiar in the classroom as chalkboards are today.
