I have been asked about the “argument” made by Rick Hess that perhaps none of Rhee’s students were actually tested in Harlem Park, and therefore we can’t tell anything about whether Rhee achieved the miracle that she claimed, so therefore the vitriolic blogger Brandenburg is full of it.
His argument is laughable.
The kids who had no test scores reported, according to the study itself, were those who were
(a) absent during the testing time period,
(b) enrolled at the school after February 1, or
(c) were in severe special education categories and thus were exempt, or
(d) students who put their heads down and didn’t answer anything at all, or scribbled all over the test, or some such thing, and thus were given a score of “1”. (I left this reasons b and d originally)
As far as I understand, there were no other reasons to exempt students. Anybody find any such reasons? In any case, NONE of those groups of students are the ones that Michelle Rhee could possibly be boasting about.
I agree that it is awfully suspicious that only sixty-four percent of the students at Harlem Park had reported test scores in 1994-5. No other school in the entire study had such low numbers (the next-lowest percentage is in the mid-70s; most are in the 80s to 90s). Of course, back then, it was rather common for principals and unethical teachers to subtly encourage their low-performing students to take testing week off, or to allow them to put their heads down or doodle during the test, or else to send them to a special room to watch films during testing period, and so on. That raises the scores for the remainder.
I can’t think of any good, legitimate reasons for the low test-reporting rate, and I have also publicly worried, in print, why the number of students tested AND the entire cohort that Rhee and her colleague taught at shrank so drastically from grade 2 to grade 3 at HPE. Such a high percentage of missing scores only occurred at that school, and at none of the other ones, either Tesseract or regular Baltimore Public schools. It makes me think that the principal at Harlem Park at that time was not doing her job.
Keep in mind that Rhee has said and written many times that she AND her team-teaching colleague raised the scores of the entire group of 70 students from the bottom to the top, i.e, from the 13th percentile to 90% of them above the 90th percentile. She uses the word “we” a lot in this regard, and of course, later, claimed that she learned about the scores from her principal, but, of course, conveniently has no records.
Let’s do a little math. There are reading scores reported for 43 third-graders at Harlem Park in 1994-5. The overall fraction of students at the school with scores reported is 64%. That would mean that there were probably about 67 third-graders overall. There is no evidence whatsoever in the report of reporting or testing irregularities at Harlem Park, except for that 64% figure. But 67 kids is more like three classes, not four classes, it seems to me.
But then again, it might just be, if you believe Rhee’s boasts, that she and her colleague taught every single one of them. (After all, 67 is less than 70.)
If you believe it is likely or possible that only 10 of Rhee & Colleague’s students got tested and that 9 out of those ten got scores at the 90th percentile — while all of the other students in that other, non-cooperating teacher got tested and they scored really low, then I would say this:
(1) I have a nice bridge in Brooklyn that I’d like to sell you.
(2) You have no understanding whatsoever about statistics or probability.
(3) Even, if by some miracle, this actually happened, then:
The only HONEST thing Rhee could have said was, “I lost all of my class data for all of my students, lost all of my roll books, and somehow almost every single one of my students was absent on the entire week that the CTBS was administered, and I forgot to call any of their parents to please, please bring their children to school that week. But, of the ten students in my and my colleague’s class that DID get tested, well, 9 of them did really, really great!”
Or else, perhaps Rhee simply found that at some unit of study, she and her colleague taught some unit of study, and over 90% of the students got scores of 90% or better on this teacher -made test (or perhaps it was one that was purchased from some commercial venture — and the company claimed that the test was ‘nationally normed’ or some such foolishness).
My response would be, “That’s nice. Good for you.”
But I would continue: “Michelle, don’t you know the difference between a teacher unit test and an actual, nationally-normed, standardized, comprehensive, end-of-the-year test like the CTBS? Didn’t you take any educational statistics courses at all? And how come you don’t have any records whatsoever to prove this, and yet you have boasted over and over and over again about this miracle that didn’t happen? Are you just full of chutzpah, or are you just stupid?”
So, I am going to revise my conclusions a little bit. It is now a tossup
(a) She’s a bald-faced liar
b) She’s stupid and clueless and can’t keep records, and doesn’t understand the first thing about educational statistics.
Either way, she has no business running any of the following:
(a) a business recruiting long-term subs (NTP)
(b) any school as a principal
(c) any school district as a superintendent or chancellor
(d) advising any governor or educational body whatsoever about anything. Unless that ‘something’ be how to lie and get away with it.
Aside: It’s no surprise that Rick Hess, who gets paid big bucks to prostitute his intellect for the right-wing millionaires and billionaires who fund the American Enterprise Institute, leapt to the defense of his personal friend, Michelle Rhee, since she is basically in the same boat. Me, I do this entire body of research and advocacy for precisely no financial remuneration whatsoever, and I am not going to go around asking billionaires or ordinary people for any funds for it. This, however, won’t prevent folks who are rabidly anti-public-employee-union for saying that I am receiving millions of dollars from a dastardly union plot to take over the nation, and that teachers are selfish and only in it for the money. If it weren’t such a serious situation, it would be laughable.
