One of the main advantages of standardized testing is that the results can be empirically documented ; therefore the test scores can be shown to have a relative degree of validity and reliability, as well as results which are generalizable and replicable. This is often contrasted with grades on a school transcript, which are assigned by individual teachers. Another advantage is aggregation. A well designed standardized test provides an assessment of an individual's mastery of a domain of knowledge or skill which at some level of aggregation will provide useful information.
Though many educators recognize that standardized tests have a place in tools used to assess student achievement, critics feel that overuse and misuse of these tests is having serious negative consequences on teaching and learning. The temptation is to use the tests to define curriculum and focus instruction. What is not tested is not taught, and how the subject is tested becomes a model for how to teach the subject. Moreover, standardized test scores are problematic tools for school accountability because the examinee scores are influenced by three things: what kids learn in school, what kids learn outside of school, and innate intelligence. Critics believe this is not possible. While it is possible to use a standardized test and not let its limits control curriculum and instruction, this can result in a school putting itself at risk for producing lower test scores, with negative political consequences.
Some critics say that some children do not do well on standardized tests, despite mastery of the material, due to testing anxiety or lack of time management or test-taking skills. This reflects the fact that tests cannot directly measure student knowledge, only the ability of students to apply knowledge in a stressful situation.
Some parents are willing to pay thousands of dollars to prepare their children for tests, a financial barrier that may give children of more wealthy parents an advantage compared to less affluent families. However this criticism would probably apply even more to testing alternatives such as portfolios or essays. Many studies also show that test coaching has little effect on scores on well-buih tests. The ability of wealthy families to pay for higher-quality education is not specifically related to standardized testing.
Which one of the regions does NOT have a long history of standardized testing？
A．China.
B．Europe.
C．United States.
D．Africa.
The latest finding comes from nutrition and immunology respected: Vitamin E boosts the immune system in older people. In an eight-month study of 88 seniors, the scientists found that those taking at least 200 international units of Vitamin E daily had stronger immune responses than those taking little or none. Alzheimer's disease. Researchers tracked 341 moderately senile patients. Those who popped 2,000 IU of Vitamin E took seven months longer to reach an advanced stage of the disease.
Rangit Kumar Chandra, a Vitamin E researcher at Memorial University of Newfoundland, Canada, says more studies are needed to learn who can benefit most and at what dose. Vitamin E thins the blood, so high doses can cause bleeding in people who also take blood thinning drags, even aspirin. Individuals with serious conditions should consult their doctors. But most people over 65, Chandra says, can take up to 200 IU with no side effects and great benefits.
