An education that alms at getting a student a certain kind of job is a technical education, justified for reasons radically different from why education is universally required by law. It is not simply to raise everyone's job prospects that all children are legally required to attend school into their teens. Bather, we have a certain conception of the American citizen, a character who is incomplete if he cannot competently asses how his livelihood and happiness are affected by things outside of himself. But this was not always the ease, before it was legally required for all children to attend school until a certain age. It was widely acteristic of all industrialized countries, we came to accept that everyone is fit to be educated. Computer education advocates forsake this optimistic notion for a pessimism that betrays their otherwise cheery out-look. Betaking on the confusion between educational and vocational reasons for bringing computers into schools, computer advocates often emphasize he job prospects of graduates over their educational achievement.
There are some good arguments for a technical education given the right kind of student. Many European schools introduce the concept of professional training early on in order to make sure children are properly equipped for the profession they want to join. It is, however, presumptuous to insist that there will only be so many jobs for so many scientists, so man2' businessmen, so many accountants. Besides, this is unlikely to produce the needed number of every kind of professional in a country as large as ours and where the economy is spread over so many states and involves so many international corporations.
But, for a small group of students, professional training might be the way to go since well-developed skills, all other factors being equal, can be the difference between having a job and not. Of course, the basics of using any computer these days are very simple. It does not take a life-ling acquaintance to pick up various software programs. If one wanted to become a computer engineer, that is of course, all entirely different computer skills are only complementary to the host of great skills that are necessary to becoming any kind of professional. It should be observed, of course that no school, vocational or not, is helped by a confusion over its purpose.
The author thinks the present, rush to put computers in the classroom is ______.

Ironically, now that photography is securely established as a fine art, many photographers find it pretentious or irrelevant to label it as such. Serious photographers variously claim to be finding, recording, impartially observing, witnessing events, exploring themselves -- anything but making works of art. They are no longer willing to debate whether photography is or is not a fine art, except to proclaim that their own work is not involved with art. It shows the extent to which they simply take for granted the concept of art imposed by the triumph of Modernism: the better the art, the more subversive it is of the traditional aims of art.
Photographers' disclaimers of any interest in making art tell us more about the harried status of the contemporary notion of art than about whether photography is or is not art. For example, those photographers who suppose that, by taking pictures, they are getting away from the pretensions of art as exemplified by painting remind us of those Abstract Expressionist painters who imagined they were getting away from the intellectual austerity of classical Modernist painting by concentrating on the physical act of painting. Much of photography's prestige today derives from the convergence of its aims with those of recent art, particularly with the dismissal of abstract art implicit in the phenomenon of Pop painting during the 1960's. Appreciating photographs is a relief to sensibilities tired of the mental exertions demanded by abstract art. Classical Modernist painting -- that is, abstract art as developed in different ways by Picasso, Kandinsky, and Matisse -- pre- supposes highly developed skills of locking and a familiarity with other paintings and the history of art. Photography, like Pop painting, reassures viewers that art is not hard; photography seems to be more about its subjects than abut art.
Photography, however, has developed all the anxieties and self-consciousness of a classic Medernist art. Many professionals privately have begun to worry that the promotion of photography as an activity subversive of the traditional pretensions of art has gone so far that the public will forget that photography is a distinctive and exalted activity -- in short, an art.
