Will flesh-and-blood teachers eventually be replaced by audio-visual gadgets? At the convention in Cincinnati last week of the National Education Association's Department of Audio-Visual Education some 2,000 people ohed and ahed over electronic marvels designed for the classroom. Proclaimed outgoing DAVI President Walter S. Bell, director of audio-visual education in Atlanta: "The familiar concept of a teacher in a classroom with only some books has completely broken down. The 'old methods simply cannot meet the challenge of the next decade, if education is to serve the humanities...
Green-eyed, Hungarian-born Artist Kepes, 53, gives the impression of being a polite and watchful visitor at first. But he is more watchful than polite, and ruthlessly articulate. As professor of visual arts at M.I.T., he is used to conducting interprofessional seminars in such elusive studies as "structure" and "continuity," and to thinking out his own esthetic positions in precise if thickly accented terms. "It is not important to me to echo Auschwitz," he says, "or Hiroshima, or the Russian slave camps. We can't compete with such brutality, and we shouldn't just mirror it. What...
...absorb hundreds of rules and procedures, study graphs, maps and reports, even occasionally take off his jet on downwind runways because airport operators prefer him to fly over open areas and avoid householders' complaints about noise. A pilot has to be able to make as many as 100 visual "fixes" per minute on his instrument panel during his busiest moments-the landing approach. He must take extra precautions to keep his health during a long flight; pilots and copilots take their meals at alternate times; American Airlines forbids crews to eat seafood because of its perishability...
...root of many of these difficulties is the multitude of professions engaged in correcting visual defects. There are the ophthalmologists, M.D. physicians who prescribe corrective lenses as a minor part of their specialty of treating eye disorders. Then optometrists,* who may not apply medicine or perform surgery, but measure visual defects, prescribe for them and fit lenses. Then there are the opticians. The ophthalmologists generally regard the other groups as journeymen technicians. But most ophthalmologists have been slow to see the potential demand for contact lenses, or their possible advantages; so the optometrists have filled the vacuum...
Special types of contact lenses are being devised for a variety of visual defects. There are two main types of bifocals, one squared off so that it will not rotate, the other made of concentric circles, with the reading prescription on the outside (this type can rotate freely). When the eye has lost its own lens because of a cataract operation, a contact can help in many cases to supply the tremendous correction needed. Another type is being tried in the early stages of glaucoma. There is evidence that contacts may slow down the progression of myopia, and hope that...
