Even the Chancellor Calls the Results ‘Sobering’

The Washington City Paper has an article on the PARCC results with way more graphs and charts than I do, and they quote even Chancellor Kaya Henderson as saying the results were ‘sobering’.

Please remind me why she still has a job?

She and several other speakers said that the PARCC results were more ‘honest’ than the old DC-CAS results, probably because the new ‘passing’ scores are lower than the old ones. I guess that means that it’s more ‘honest’ to say that students are doing worse than we were previously led to believe, under the current regime of all-testing-all-the-time and turn-half-the-students-over-to-unregulated charters?

 

PARCC Results Released in DC

I just got back from watching the public release of the results of the PARCC test that students in Washington DC took about 7 months ago.

(Let that sink in: it took the testing company, and their consultants, and the city’s consultants, over HALF A YEAR to massage the data into a releasable form. So much for having these tests be able to be used to ‘inform instruction’ or help teachers figure out what kind of help their students need. It’s now the last day of November, and the students have been in school since August. What kind of help is that to teachers or parents? And tho I haven’t looked at the released school scores or samples of what the teachers will see, I’m not optimistic. If the past is any guide, the scores themselves will be essentially useless as well…)

(It won’t take so long next time, we were assured…)

I got to see Mayor Bowser, Councilman Grosso, Chancellor Kaya Henderson, [powerless] Superintendent Hanseul Kang, and Deputy Mayor for Education Jenny Niles, and charter honcho Scott Pearson perform and answer some mostly-lame questions from some members of the media.

What we saw were that advanced students in DC (largely white ones) do exceedingly well on this PARCC battery of tests, and that others (blacks; hispanics; SPEDs; students on free or reduced lunch; ELLs; or Students At Risk) do much worse. Which of course is  the very same result we’ve seen on the NAEP for a couple of decades.

In fact, of all the cities and states measured on the NAEP, Washington DC has the very widest gaps in test scores between the Upper Caucasia Haves and the Have-Nots everywhere else, and those gaps are if anything getting wider.

It was interesting to hear Henderson’s defenses of the results, which still showed very low percentages of most students “passing” the PARCC. She said, among other things, that

(1) since students at the lower grades generally scored higher than those at the upper grades, that show’s we are on the right path [seems to me it shows the exact opposite; the longer that students have been exposed to “Reform”, the worse they do… and

(2) It takes a long time, you can’t just expect to turn a switch and have everything be wonderful overnight, we need lots of wrap-around services and a longer school day and school year and support for teachers.

Regarding the latter excuse: isn’t that exactly what teachers were condemned for saying under Chancellor Rhee, whose understudy was none other than Kaya Henderson? Didn’t Rhee imply that the only reason that poor students did poorly in school was that their greedy, lazy teachers, empowered by their evil union, refused to teach them anything? And that anybody who said that it’s a lot harder to teach impoverished students of color with chaotic families (if any) than it is to teach middle-class children with educated parents – why those people were just making excuses for poverty?

 

Revised HS PARCC ‘pass’ rates in English and Math in DC public and charter schools

My original graphs on the ‘pass’ rates for all DC publicly-funded high schools were incomplete, because I was using OSSE data only (Office of the State Superintendent of Education). A reader showed me where the DC charter school board (DC PCSB) posted their PARCC statistics and that gave me the pass rates for a couple of additional schools (Maya Angelou and BASIS IIRC). So here are the revised graphs which you can click on to enlarge:

2015 Math PARCC 'pass' rates, both public and charter schools in DC

2015 'pass' rates, public and charter high school math, PARCC, DC, 2015

2015 ‘pass’ rates, public and charter high school math, PARCC, DC, 2015

Note how many fewer students passed the PARCC math test than the reading test in DC. I haven’t yet seen any of the actual questions on either of the tests. But if these were tests that I had written and was using as a teacher with my students, I would likely conclude that the one with the much-lower scores was simply a much harder test, and I would probably do one of the following:

(A) “scale” the scores so that more students would pass, or else

(B) throw out the test results and try teaching with a different approach altogether, or else

(C) throw out the test and make one that at least a majority of students could pass if they’ve been paying attention.

{At my last school, if f I failed 80 to 90% of my students, I would have gotten an unsatisfactory evaluation and probably have gotten fired.}

Of course, this being the era when multi-billionaires who hate the very idea of public schools are in charge of said public schools, neither A, B or C will happen. In fact, my understanding is that the ‘cut’ scores for each of the categories of grades (meets expectations and so on) were set AFTER the students took the test, not in advance. So it was very much a politico-social decision that the vast majority of students were SUPPOSED to fail the math test.

Let me note strongly that by far the most effective way to have really good test scores for your school is to let in ONLY students who already get strong test scores. That’s how Phillips Exeter or Andover Academies or Riverdale or Sidwell Friends or or the Chicago Lab or Lakeside private schools do it, and that’s how Banneker, School Without Walls, Washington Latin, and BASIS do it. (Partial disclosure: I and some of my immediate family either went to, or worked at, some of those schools.) Teachers who are successful at those elite schools have a MUCH easier time teaching those students than do those who try to teach at school with large numbers of at-risk students, like Washington Metropolitan, Ballou, Cardozo, Maya Angelou, or Options public or charter schools. Idealistic teachers from elite schools who do transfer to tough inner-city public schools generally crash and burn, and I would predict that one of the easiest ways to lose your teaching job these days is to volunteer to teach at any one of the five latter schools.

Where DC is #1 on the NAEP

Of all the states and territories tested on the 2015 NAEP, there is one place where DC is Number ONE!

Unfortunately, it’s not a good #1.

We have, by far, the largest gaps between percentages of white and black students who are deemed ‘proficient’ or better. On every single test (8th grade, 4th grade, reading and math).

DC also the largest gaps between percentages of white and hispanic students – on every single test.

Our DC gaps are at least double the national gaps. And that’s not good. In fact, the gaps are anywhere between double and two-and-a-half times as large as the gaps nationally or the median of all states, as you see here:

gaps b-w and w-h

Kaya Henderson and Michelle Rhee really have some tremendous accomplishments, don’t they?

————

These scores, by the way, are for a carefully-selected sample of ALL students in Washington, DC – public, charters, private, and parochial. Rhee and Henderson and the various DC mayors have been in total control of all public and charter schools since 2007, with a school board that has exactly zero power and a teachers’ union that has lost almost any power to do anything meaningful to support teachers. And we have a teaching and supervisory force that is either brand-new (hired by Rhee or Henderson or by the heads of the many charter schools) or has passed all of the extremely difficult evaluations not once, but many times.

Trends on the NAEP give a clue as to why Arne Duncan quit

Seeing the rather large drop on the NAEP scores for students across the nation – results released at midnight last night – gives me the idea that Arne Duncan (secretary of education for the past 7 years) quit rather than face the blame for his failed policies. After all, he (and the rest of the billionaire deformer class) have been promising that if you open tons of unregulated charter schools, use numerology to fire many of the remaining veteran teachers, and make education into little more than test prep for all students of color or those who come from poor families, then the test results will improve.

Well, they didn’t improve.

I will let you see for yourself how the percentages of students deemed ‘proficient’ in 4th grade and 8th grade on the NAEP at the national level generally dropped. I include DC (where I come from), and in five other states – two that are high-performing (NH and Massachusetts) and three that are low-performing (CA, AL and NM).

The one bright spot for District residents is that DC is no longer the last in the nation in every category! DC students now have slightly higher percentages proficient in certain categories than two other impoverished states – New Mexico and Alabama, as you can see in the graphs below. (The graph for the District of Columbia is the light blue one at the bottom,)

On the other hand, the increases in percentages of students ‘proficient’ in DC since 2008, the first year after mayoral control was imposed and the elected school board was neutralized, are nothing but a continuation of previous trends.

As usual, if you want to take a closer look, click on the graphs.

Surprising Comparison of Charter and Regular Public School ‘Pass’ Rates on the HS PARCC

I was actually rather surprised to see that significantly larger percentages of regular DC public school students ‘passed’ the PARCC in both math and in reading than did DC charter school students.

If you don’t believe me, look for yourself at the OSSE press release.

What it says is that in the DC charter schools, 23% of the students ‘passed’ (got a 4 or a 5) on the English portion, whereas in the regular DC public schools, 27% ‘passed’.

And in math, they claim that only 7% of the charter school students ‘passed’, but 12% of the regular DC public school students passed.

Are you surprised, too?

A Few PARCC Scores Have Been Released for DC Public Schools

If you would like to see how District of Columbia public high school students did on the PARCC, you can look here at a press release from DCPS administration. This test was on ELA (reading) and Geometry. The scores for grades 3-8 have not yet been released.

The disparities in ‘pass’ rates between the DCPS magnet schools (Banneker and Walls) and every other DC public high school are amazing, particularly in geometry. Notice that several schools had not a single student ‘pass’. This year’s test gives students scores from 1 to 5; only a score of 4 or 5 is considered ‘college and career ready’ — although no studies have actually been done to determine whether that statement is actually true. Banneker and Walls have the lowest rates of students labeled ‘at risk’.

Here are two graphs which I cut-and-pasted from the press release. Click on them to enlarge them.

HS-PARCC dc ELA

HS-PARCC geometry

Given what I’ve seen of the convoluted questions asked on released sample PARCC questions, it is no wonder that ‘pass’ rates dropped a lot this year, compared with previous years. The DC-CAS wasn’t a very good test, but PARCC is terrible.

Please keep in mind that public education in the District of Columbia has been under the control of DEformers like Michelle Rhee, Kaya Henderson, and the Gates and Broad foundations, for over 8 years now. The students taking this test last spring have been under their rule since they were rising third graders. Every single teacher in DCPS was either hired by Rhee or by Henderson or else passed numerous strict evaluations with flying colors, year after year, and has been teaching just as they were directed to – or else.

And this is the best that the DEformers can do?

Mental Math, Traditional Math, and Best Methods

James Tanton is one of the most insightful teachers of teachers of math I’ve come across in a long time.

In this video and this essay, he explains how some parents feel mystified by some of the newer style of math problems that children are bringing to their parents for help. Clearly, some of the problems (like the 32-12 one which fills up an entire page in a child’s workbook) are being done in a tortured, time-wasting method. However, if you take a more difficult problem, such as 103 – 87, you can do this completely in your head by adding small increments (MENTALLY) to the 87 until you get to 103.

This is a reasonable thing to do, much like people count out (or used to count out) change into a customer’s hand.

In this case, from 87 to 90 (which is a much ‘nicer’ number than 87) we need to go up by 3.

Then from 90 to 100 (which is getting closer to our goal), we go up by 10. So we’ve gone up by 13 all together.

Then from 100 to 103 is three more, so we’ve gone up by 16, which means that 103 – 87 is 16.

I would be crazy to write all those steps out! – which is unfortunately what the poor child was asked to do.

But doing it quickly in your head makes a lot of sense.

As Tanton says, let’s get rid of laborious, tortured, time-wasting algorithms and examples, but let’s keep the thinking and understanding.

See Jersey Jazzman use the Gaussian Distribution to Show that Arne Duncan and Mike Petrilli are full of it

Excellent lesson from Jersey Jazzman showing that the old tests produce pretty much the same distribution of scores as the new tests.

old and new tests

He has superimposed the green scores from 2008 on top of the 2014 scores for New York state in 8th grade reading, and basically they have almost the same distribution. Furthermore, a scatter plot shows nearly the same thing, and that there is a nearly perfect correlation between the old scores and the new scores, by school.

old and new tests again

Read his article, which is clear and concise. I don’t have time to go into this in depth.

A 3 minute news segment on the NY lawsuit against Value-Added Modeling

Even-handed video from Al-Jazeera interviewing some of the people involved in the anti-Value-Added-Model lawsuit against Value-Added Model evalutations of teachers in New York state.

You may have heard of the lawsuit – it was filed by elementary teacher Sherri Lederman and her lawyer, who is also her husband.

Parents, students, and administrators had nothing but glowing praise for teacher Lederman. In fact, Sherri’s principal is quoted as saying,

“any computer program claiming Lederman ‘ineffective’ is fundamentally flawed.”

Lederman herself states,

“The model doesn’t work. It’s misrepresenting an entire profession.”

Statistician Aaron Pallas of Columbia University states,

“In Sherri’s case, she went from a 14 out of 20, which was fully in the effective range, to 1 out of 20 [the very next year], ineffective, and we look at that and say, ‘How can this be? Can a teacher’s performance really have changed that dramatically from one year to the next?’

“And if the numbers are really jumping around like that, can we really trust that they are telling us something important about a teacher’s career?”

Professor Pallas could perhaps have used one of my graphs as a visual aid, to help show just how much those scores do jump around from year to year, as you see here. This one shows how raw value-added scores for teachers in New York City in school year 2005-2006 correlated with those very same teachers, teaching the same grade level students in the very same schools the exact same subjects, one year later. Gary Rubinstein has similar graphs. You can look here, here, here, or here. if you want to see some more from me on this topic.

The plot that follows is a classic case of ‘nearly no correlation whatsoever’ that we now teach to kids in middle school.

In other words, yes, teachers’ scores do, indeed jump around like crazy from year to year. If you were above average on VAM one year – that is, to the right of the Y axis anywhere, it is quite likely that you will end under the X-axis (and hence below average) the next year. Or not.

I am glad somebody is finally taking this to court, because this sort of mathematics of intimidation has got to stop.
