This is a sobering read, some information from the article written by Peter Greene Forbes.com:
"Test scores can be raised with several techniques, and most of those techniques have nothing to do with providing students with a better education. Drill the test prep. Take at-risk students out of electives and make them take test-related courses instead. And have teachers learn, over the years, how to teach more directly to the test. But do you want higher test scores or better education? Because those are two unrelated things."
"Teachers have said, repeatedly, that the tests don’t measure what they claim to measure, and that the educational process in schools is being narrowed and weakened in order to focus on testing. Teachers have said, repeatedly, that the Big Standardized Tests are a waste of time and money and not helping students get an education. Teachers have been saying it over and over and over again."
