Famous quotes containing the words natural and/or materials:
“As writers become more numerous, it is natural for readers to become more indolent; whence must necessarily arise a desire of attaining knowledge with the greatest possible ease.”
—Oliver Goldsmith (1728–1774)
“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)
