...growing textbook market for adult education. Educational concern for special opportunity for the gifted child-and the unusually backward-has meant a proliferation of textbooks on the same subject at different levels. Holt now has four college freshman mathematics texts replacing what was once a single staple freshman algebra. From teaching electronic computers what to do man is learning new ways to teach himself: Doubleday and Harcourt this year published textbooks utilizing novel computer techniques to teach children subjects such as English...
Originally, junior high schools required their students to study algebra and foreign languages in the seventh and eighth grades. Urging a partial return to this plan, Conant suggests that junior high schools institute "elite" classes...
...Manchester (Conn.) High School, a student needs a B or better in all subjects to make the honor roll, and bright, spunky Charlene Southergill, 17, seemed a shoo-in. In the last quarter of her junior year this spring, she got a B in algebra, B in college-level biology, B in college-level English, and A in college-level American history. Was this enough to land her on the honor roll? Not at all: Charlene got a C in archery...
...shushed. The teacher must first demonstrate the rigmarole of subtracting 5 from both sides of the equation to get 4. Says Beberman: "The student had a notion of what a variable really is - and probably for the last time." Numbers v. Numerals. In his own elementary algebra course, Beberman first focuses on the semantic difference between a number and a numeral. One is a permanent concept, the other a mere name for it. A number has many aliases. Just as the same man may be called President. General, Ike or Eisenhower, so the word seven symbolizes an idea that...
What distinguishes his method is the emphasis on discovery. To find out algebra's basic laws for themselves, Beberman's students solve similar problems until the concept involved becomes clear. On the second day, they work at such disarming exercises as stating whether it is true that __ +984 = 984+793. The point is to discover that adding numerals in varying orders does not affect the sum. Later they watch a movie projector running backward and forward, extract the rules of positive and negative multiplication. Then they see two unpunctuated signs : "Slow Children at Play" and "Save Rags...
