What are some of the limitations in standardized testing and research?

Seberal problems I have discovered with standardized testing include 1) sometimes they are biased towards a particular group by design (such as race, those with disabilities, or towards people with low levels of education), 2) tests can me misused if the person administering the test does not understand the proper way in which to give it, or they make a mistake in interpreting the results, and 3) reliance on standardized testing scores is overrated; it does not always present an accurate picture of the "testee"and some people do not perform well on tests due to their learning style.  If you are looking for more information, I would like to suggest the PsychInfo database.  You need to have access to it through a school, but if you can arrane it, it is an excellent resource.

I would guess none since testing is done throughout the qualification phase and there have been no major stories of test failures.

Limitations on file size would be my guess.

On the Praxis as with other standardized tests, you  get points for correct answers, so if you miss one or get one incorrect, it will not count against you.  Just answer as many as you can, you'd probably be better off just giving the answer you think might be correct, because then you might have a better chance at getting it correct than if you just left it blank.

I would say check with your high school counselor to see if the deadline has passed already for the dec testing time. If not, then you should be good. P.S. Ignore those negative people that tell you that you CAN"T do something! Good luck!

Yup.  It's new this year.  There isnt an example test available just yet.  [my wife is a special ed asst in 3rd grade NYstate]

Do a web search for the parameters.  We would need much more information from you on sample types, volumes, etc and you capabilities, instrumentation available, etc.  All of these are factors in deciding a method.

It is hard to help without  knowing the specifics of what information will need to be in it.  Take your big points that have to be gotten across and then bullet relevant info. beneath.

To my knowledge, there is no min sample size.  In fact, that is one reason K-S might be used, in that Chi Square g-o-f tests can require a relatively larger sample size.

In psychology, researchers must pass an ethics test before conducting research using human participants.  Both ethics and values can be taught, but not all will follow them.

In some sense, no test reflects what a person REALLY knows.  All tests pick some set of questions to "sample" what a person knows, and then extrapolate from there.  (There is virtually no test which goes methodically through every piece of knowledge to see exactly what a person knows or doesn't know.)\n\nBeyond this, there's always the chance that, due to psychological factors or due to the physical design of the test, a student will give a wrong answer even though she or he knows the right answer.\n\nBut the limitations described above apply to all tests.  Standardized tests are typically designed carefully to minimize sources of error.  \n\nOne of the things that standardized tests have in their favor is that they don't attempt to try to measure "raw" knowledge.  Rather, they ask the same questions of a group of people and then give a ranking within that group.  Who knows the most (scores the highest)?  Who knows the least (scores the lowest)?\n\nBecause the standardized tests give ranked scores, then, they're not designed to reflect "what students really know."\n\nI guess this means that the basic answer to your question is that standardized tests do "reflect" what students really know, but that they are not designed to give a direct measure of what students really know.

Well, I don't think it's ever been determined because it's very hard to do a study on it. "Information" is very vague, and the results will fluctuate wildly.\n\nBut people with high intelligence would have a higher capacity to learn.

Standardized testing refers to the uniformity of procedure in administering and scoring a test.  This standardization is essential in order to compare one person or group of persons with another person or group.  And, to compare a person with him or herself over time.\n\nThe issue you are raising is not with standardized testing, but with how test content drives the content of the school's curriculum.  Restricting course content to the areas that will be tested ensures that more students will pass the test.  And, some school administrations do evaluate their teachers on the basis of numbers successful on the test.\n\nIn my opinion, the nation-wide emphasis on specific skills has negatively impacted the richness of past public primary and secondary education.  More and more parents and students seem to be coming to the same conclusion that you have reached.  Some are switching to home schooling or enrolling in private schools.  However, you can become responsible for your own enrichment without withdrawing from the public schools.  Simply change your expectations of what they are able to offer.  However, do your very best on the TAKS.  It is a serious endeavor.\n\nYou ask if this is fair.  The answer depends on how you define fair.  There is currently a powerful movement in this country to improve student performance.  It may be instructive to use causal analysis to examine the source of this movement.  Your questions are good ones.  Continue to be inquisitive.\n\nI hope this helps.  If you are interested, read more about the No Child Left Behind Act and how communities around the country have responded.

A school district or state can implement any educational standard they want to impose.\n\nPlease note, however, that the MEAP test is not meant to judge your son's ability per se.  The real point of that test is to assess the SCHOOL.  The people that look at the results of that test are asking this question: "Is the school teaching its students everything its supposed to be teaching?"\n\nThe only way they can find this out is to issue a standardized test.  If the majority of the students are at the level prescribed by educational standards set by the legislature, then the school is doing its job.  They're NOT concerned with how your son...or any other individual student...performs on the test.  They're only interested in the bigger picture.\n\nThe tests your son should be worried about are the ACT and the SAT, since that score asseses the likelihood of success at the college level.\n\nGood luck.

There are many test methods available depending upon the type of material, cost, availability of in-house, field test or lab test capabilities required.\n\nYou can get a listing of test methods and suppliers from www.asnt.org

anything that involves testing human diseases. it is illegal to test on humans so they use lab rats... it's always expirimental because they can't practice on the people... \n\nhow about...  cloning?  ... stem cells from aborted fetuses as genetic material to replace organs? .... monkey sex in space? .... effects of radiation on desert life in nevada?.... military anything... oh my, how about our own lives?  i do expirimental research on my own life every day.

IMO, standardized testing has been mandated (No Child Left Behind) because cronies of Bush &Co own companies that produce, administer, and score standardized tests.
