31、d by asking family members, friends or colleagues are beyond the capability of the extended family to resolve. Where to turn for expert information and how to determine which expert advice to accept are questions facing many people today. In addition to this, there is the growing mobility of people
32、since World War . As families move away from their stable community, their friends of many years, their extended family relationships, the informal flow of information is cut off, and with it the confidence that information will be available when needed and will be trustworthy and reliable. The almo
33、st unconscious flow of information about the simplest aspects of living can be cut off. Thus, things once learned subconsciously through the casual communications of the extended family must be consciously learned. Adding to societal changes today is an enormous stockpile of information. The individ
34、ual now has more information available than any generation, and the task of finding that one piece of information relevant to his or her specific problem is complicated, time-consuming and sometimes even overwhelming. Coupled with the growing quantity of information is the development of technologie
35、s which enable the storage and delivery of more information with greater speed to more locations than has ever been possible before. Computer technology makes it possible to store vast amounts of data in machine-readable files, and to program computers to specific information. Telecommunication deve
36、lopments enable the sending of messages via television, radio, and very shortly, electronic mail to bombard people with multitudes of messages. Satellites have extended the power of communications to report events at the instant of occurrence. Expertise can be shared worldwide through teleconferenci
37、ng, and problems in dispute can be settled without the participants leaving their homes and/or jobs to travel to a distant conference site. Technology has facilitated the sharing of information and the storage and delivery of information, thus making more information available to more people. In thi
38、s world of change and complexity, the need for information is of greatest importance. Those people who have accurate, reliable up-to-date information to solve the day-to-day problems, the critical problems of their business, social and family life, will survive and succeed. “Knowledge is power“ may

We are not about to enter the Information Age, but
40、instead are rather well into it.“ Present predictions are that by 1990, about thirty million jobs in the United States, or about thirty percent of the job market, will be computer-related. In 1980, only twenty-one percent of all United States high schools owned one or two computers for student use.
41、A new survey revealed that half of United States secondary schools have fifteen or more computers for student use. And now educational experts, administrators, and even the general public are demanding that all students become “computer literate“ By the year 2000 knowledge of computers will be neces
42、sary in over eighty percent of all occupations. Soon those people not educated in computer use will be compared to those who are print illiterate today. What is “computer literacy“? The term itself seems to imply some extent of “knowing“ about computers, but knowing what? The current opinion seems t
43、o be that this should include a general knowledge of what computers are, plus a little of their history and something of how they operate. Therefore, it is vital that educators everywhere take a careful look not only at what is being done, but also at what should be done in the field of computer edu
44、cation. Today most adults are capable of utilizing a motor vehicle without the slightest knowledge of how the internal-combustion engine works. We effectively use all types of electrical equipment without being able to tell their histories or to explain how they work. Business people for years have
45、made good use of typewriters and adding machines, yet few have ever known how to repair them. Why, then, attempt to teach computers by teaching how or why they work? Rather, we first must concentrate on teaching the effective use of the computer as the tool is. “Knowing how to use a computer is what

48、w or deposit money in scattered locations, whether or not the local branch bank is open. For many of us the “cashless society“ is not on the horizon-its already here. While computers offer these conveniences to consumers, they have many advantages for sellers too. Electronic cash registers can do mu
49、ch more than simply ring up sales. They can keep a wide range of records, including who sold what, when, and to whom. This information allows businessmen to keep track of their list of goods by showing which items are being sold and how fast they are moving. Decisions to reorder or return goods to suppliers can then be made. At the same time these computers record which hours are the busiest and which employees are the most efficient, allowing personnel and staffing assignments to be made accordingly. And
