Part Ⅳ English-Chinese Translation
The standardized educational or psychological test that are widely used to aid in selecting,
classifying, assigning, or promoting students, employees, and military personnel have been the target of recent attacks in books, magazines, the daily press, and even in congress. 71 )The target is wrong, for in attacking the tests, critics divert attention form the fault that lies with ill-informed or incompetent users. The tests themselves are merely tools , with characteristics that can be measured with reasonable precision under specified conditions. Whether the results will be valuable , meaningless, or even misleading depends partly upon the tool itself but largely upon the user .
All informed predictions of future performance are based upon some knowledge of relevant past performance: school grades, research productivity, sales records, or whatever is appropriate. 72 )How well the predictions will be validated by later performance depends upon the amount , reliability , and appropriateness of the information used and on the skill and wisdom with which it is interpreted. Anyone who keeps careful score knows that the information available is always incomplete and that the predictions are always subject to error.
Standardized tests should be considered in this context. They provide a quick, objective method of getting some kinds of information about what a person learned , the sktlls he has developed, or the kind of person he is. The information so obtained has, qualitatively, the same advantages and shortcomings as other kinds of information. 73)Whether to use tests. other kinds of information, or both in a particular situation depends, therefore, upon the evidence from experience concerning comparative validity and upon such factors as cost and availability.
74)In general,the tests work most effectivelv when the qualities to be measured can be most precisely defined and least effectively when what is to be messured or predicted cannot be well defined. Properly used, they provide a rapid means of getting comparable information about many people Sometimes they identify students whose high potential has not been previously recognized, but there are many things they do not do. 75)For example, they do not compensate for gross social inequality, and thus do not tell how able an underprivileged youngster might have been had he grown up under more favorable circumstances.
