I think my inbox was too "exhausted" to receive messages. Did the "bounced" message indicate that fact? ------------- I will try to find some more time to comment on your comments. I think your ideas are interesting conjectures (hypotheses?); however, trial approaches toward solving the CALCULATOR-COMPUTER PROBLEMS might be reasonable just as trial test items are administered for feedback and modification. I am a strong believer in EVolutionary OPerations. As long as the system is not destroyed, incremental exploration toward more optimum conditions seems like a good strategy.
Thanks for the thoughtful ideas. Those ideas are what can lead to improved solutions to interesting problems.
We'll see you in Minneapolis.

a) No manufacuturer would want that headache b) When is a kid going to learn how use the calculator they choose? If they have one, why "borrow" one?

At what and whose cost? Ultimately, the kids'.

So would all the lawyers -- if there is any difference, would separate grading scales be done for each calculator? If there is a difference, that MUST decrease the reliability of the test in the college dept eyes.
> The suppliers should be glad to pay the cost of shipping.
What they should do, and what they can economically justify are two different things. Where will they get these calculators? And what will they do with the "used" calculators after that? Keep an inventory for items that have half-lives of 6 months? There are hundreds of thousands of these tests given each year! Will they re-package these calculators? Who would buy them? It is a major effort to get the test readers to the different sites at the same time. Will FedEx, UPS, U.S. Post Office, etc. also donate their services????

And training people to do this, and paying them per diem, and verifying the loading is correct -- and who will find these people at all the sites across the country? And who will verify that the software disks have not picked up any viruses, assuming they would re-use the disks?

And who will unload all the other software, verify the software as loaded, verify that it is UNloaded, and who will eat the cost of all the disks needed to load the software? Who would train these folks? What if I got into the test, did not like what I was seeing, and was knowledge- able to trash the software? Can I now claim that I deserve a re-test?
And what if the location of the exam does not now have computers? Where will they come from, who will install and take them away, and what will be the market for those newly used computers? Who would be willing to lease thousands of computers for one day?

If I were a stockholder in any company that did that, I would promptly start a campaign to get new boards of directors or whatever. I'm not investing my hard-earned $$$ in a company that throws inventory away like that.

But ETS/AP is not in the business of providing marketing research -- in the unlikely event the marketing research would have any value more than 6 months out, I would still as a parent of a daughter who will in all likelyhood take AP tests, demand every possible inch of reliability and validity for the test's purpose: evaluate her achievement with an eye toward offering advanced placement. I do not see why I would want any other ox gored, nor do I see why I should pay a great deal more money to support a testing effort with a newly vitiated responsibility.
