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.

I don't have the scoring guide, but if it doesn't accept both answers
it's simply wrong: both #1 and #3 are equivalent and SED needs to issue
a scoring update. (It didn't ask for simplest form: it said
"equivalent.") And even if SED marks both correct, that was needlessly
confusing to students, and upsetting for some.

#19) I know #3 is the least wrong but I think y = cos^-1 (x) implies a
function and graph #3 does not have a restricted range.
<javascript:parent.wgMail.openComposeWindow('mclemens@twcny.rr.com')>

<javascript:parent.wgMail.openComposeWindow('mclemens@twcny.rr.com')>
Either the range is restricted to make it a function, so the range is
[0,pi], or the range is not restricted and the range is (-inf,inf).
There is no interpretation that makes any of the given choices correct.
On the other hand, I don't see that this will lead students astray: even
if they know it's wrong, #3 is clearly "least wrong."

#30) I?d like to give full credit to an equation with either y = x^2 ?
6x ? 27 or 0 = x^2 ? 6x ? 27.

From NYS Glossary for A2T:
<javascript:parent.wgMail.openComposeWindow('mclemens@twcny.rr.com')>

<javascript:parent.wgMail.openComposeWindow('mclemens@twcny.rr.com')>
?root of an equation (A) ( A2T) A solution to an equation of the
form f ( x ) = 0.
<javascript:parent.wgMail.openComposeWindow('mclemens@twcny.rr.com')>

<javascript:parent.wgMail.openComposeWindow('mclemens@twcny.rr.com')>
Example: A root of the equation y = 6 x ? 18 is 3 because when 3 is
substituted in for x , the value of y = 0.
<javascript:parent.wgMail.openComposeWindow('mclemens@twcny.rr.com')>
Example: The roots of are and . The equation is true if we
substitute either or into the equation.?

<javascript:parent.wgMail.openComposeWindow('mclemens@twcny.rr.com')>
I'm a little unclear myself on "root of an equation" vs. "zero of a
function" vs. "root of a function." etc. ( Steve Goldman's can of worms
in a separate message.) But that glossary entry is unambiguous: both of
<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. Really, there should be a stated domain restriction so it is
clear which branch to choose.
<javascript:parent.wgMail.openComposeWindow('mclemens@twcny.rr.com')>

<javascript:parent.wgMail.openComposeWindow('mclemens@twcny.rr.com')>
I agree. 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

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. But was the student expected
to do that?
