Famous quotes containing the words phase, change and/or materials:
“The problem of the twentieth century is the problem of the color-line—the relation of the darker to the lighter races of men in Asia and Africa, in America and the islands of the sea. It was a phase of this problem that caused the Civil War.”
—W.E.B. (William Edward Burghardt)
“The incessant repetition of the same hand-work dwarfs the man, robs him of his strength, wit, and versatility, to make a pin- polisher, and buckle-maker, or any other specialty; and presently, in a change of industry, whole towns are sacrificed like ant-hills, when cotton takes the place of linen, or railways of turnpikes, or when commons are inclosed by landlords.”
—Ralph Waldo Emerson (1803–1882)
“Young children learn in a different manner from that of older children and adults, yet we can teach them many things if we adapt our materials and mode of instruction to their level of ability. But we miseducate young children when we assume that their learning abilities are comparable to those of older children and that they can be taught with materials and with the same instructional procedures appropriate to school-age children.”
—David Elkind (20th century)
