NYS is killing me!!
I have been teaching for 22 years. It is my passion..everybody knows it..friends..relatives..coworkers..my students
They want to "grade" me on how my students do on the assessment tests....Can they make a fair test???? Do they have to jam pack the curriculum so I have to teach at lightning speed and hope my students catch everything!!
This has to change!! My school is 7-12. This year I taught 7th grade as well as Alg 2/Trig. Both courses were miserable. I had to fly through topics and felt all along that it is so unfair to my students. There was nothing I could do about it. On the 7th grade assessment Question: Which is not a polynomial? choices A) 4 B) 4x/y C) 3x + 5 D) 4xy. I understand that the answer is B by definition but the question should have said Which is not a monomial???
Sorry for the ranting. I can't take this. I wish there is something I could do.

I think the SED scoring team should expect a bunch of calls tomorrow. I think the scoring guide needs clarification or changes for several questions.

But that glossary entry is unambiguous: both of Meg's answers should be accepted. <javascript:parent.wgMail.openComposeWindow('mclemens@twcny.rr.com')> #32) Doesn?t using f^-1(x) imply that answer should be a function? I think stating just one branch of the inverse of the parabola should be accepted.

If the question said "find the inverse," then the inverse could be a relation, not a function, and the only correct answer would be both branches: plus/minus sqrt(x+6). But f^-1(x) implies an inverse *function*, so the only actually correct answer is "no inverse function." But that's not what the question intended, so SED should accept both +sqrt and +/-sqrt, and they should accept "no inverse function." (And they should accept -sqrt from the student who is mathematically confident enough and deliberately contrarian enough to give that answer.) <javascript:parent.wgMail.openComposeWindow('mclemens@twcny.rr.com')> <javascript:parent.wgMail.openComposeWindow('mclemens@twcny.rr.com')> On #31, I think I agree with Cindy Kohl: what work is needed?? But I don't teach A2T: for a plug-it-in-to-the-calcualtor question, is the student expected to say what she did on her calculator? <javascript:parent.wgMail.openComposeWindow('mclemens@twcny.rr.com')> <javascript:parent.wgMail.openComposeWindow('mclemens@twcny.rr.com')> And I'll add one more: I'm not very happy about #27. Just looking at it, it looks like either a log function or a sqrt function (0.5 power), so either a log or power regression seems reasonable. Sqrt would go through the origin and log would not, but can you tell if that scatter plot goes through the origin or not? I can't. <javascript:parent.wgMail.openComposeWindow('mclemens@twcny.rr.com')> If I take the time to type all the data into my calculator and do the regressions, log is clearly better.
