Successful teachers are little less than paragons if one is to judge from recent discussions and from reports of empirical observations and experimental research dealing with teachers' personalities. One writer lists nineteen desirable qualities, including integrity, maturity, dominance, and diligence. Another investigator catalogues twenty- nine attributes, such as introversion, vitality, punctuality, and per- sistence. A third researcher tabulates only six traits, but among them is competence in computing with two-digit numbers. A fourth author reports that "speed of tapping" and "right and left hand coordination" (supposedly measures of temperament) distinguish effective from non-effective teachers. Another writer thinks that intelligence is im- portant but maintains that we cannot prove that fact. Effective teach- ers, one states, are peppy and popular, with pleasing voices. One other example: a teacher should have magnetism, self-control, and enthusiasm. A complete listing would contain a finite number of attributes, but the number seems to be approaching infinity as a limit.
