[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote]Checked with a mathematician. He laughed. Opposite is not a math word.[/quote] LOL! Just asked by DH. He asked: Do you mean "inverse"? Never heard "opposite" at MIT.[/quote] Well, if DH never heard it at MIT, then obviously it doesn't exist! No, wait... http://www.montereyinstitute.org/courses/Algebra1/COURSE_TEXT_RESOURCE/U02_L1_T1_text_final.html (I bet he never heard about "regrouping" or "composition/decomposition" at MIT, either.)[/quote] The diff is that Monterey defined their term. Using terms like regrouping is ok for teaching but they are a means to an end, not an end in itself. Testing should be about knowledge of subject matter. [/quote] Monterey used the term in the same way that the PARCC test question did. Therefore, the PARCC test question did not make up the idea. Also, math subject matter includes math vocabulary.[/quote] I would have had less of a problem if the problem said something like Find the opposite about zero or opposite with respect to zero. Opposite is a relative term and needs to be qualified. This question just shows the test is written to a low standard and by people who are limited in mathematical knowledge themselves and believe the end product of education should be regurgitating what one was taught in a closed system, instead of knowledge that will connect with the broader world and extend into deeper study of real, not constructed, subject matter.
