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 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.

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?

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.

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

Weekly Roundup of Educational Resistance by Bob Schaeffer

{As usual, this list is collected and distributed by Bob Schaeffer, not by me.}

The U.S. Senate has joined the House of Representatives in responding to growing, grassroots pressure by voting to overhaul “No Child Left Behind” (NCLB). The bills passed by both the Senate and House reflect widespread rejection of failed top-down, test-and-punish strategies as well as the “NCLB on steroids” waiver regime dictated by Arne Duncan. While neither version is close to perfect from an assessment reform perspective, each makes significant progress by rolling back federally mandated high-stakes, eliminating requirements to evaluate educators based on student test scores, and recognizing opt-out rights. FairTest and its allies will closely monitor the conference committee working on compromise language to make sure the gains remain in the final bill sent to President Obama — the alternative is to keep the yoke of NCLB-and-waivers in place for at least two more years, if not much longer. Meanwhile, organizers in many states are keeping the spotlight on the problems of test overuse and misuse, modeling better practices and winning additional policy victories.

A closer look at charter and regular public school enrollments, percentages of students at risk, and percentages of students ‘proficient’

Here is another look at the brand-new data concerning four variables in the District of Columbia schools, about which I wrote a couple of days ago. The difference here is that the dots representing the schools are more-or=less proportional to the size of the student body.

1. Is this a regular public school, or a charter school (blue or red):

2. What fraction of the kids at that school are officially considered to be At Risk? (That’s the scale along the x-axis at the bottom of the page)

3. What is the average percentage of the kids at that school are ‘proficient’ in reading and math on the DC-CAS? (That’s the scale along the y-axis at the left-hand side of the page)

4. How big is the school? (That’s the size of the dot, more or less; the legend is at the bottom left-hand corner of the graph)

Time spent looking carefully at this graph will be well-spent. If you click on it, it will expand.

It will certainly show that charter schools have not revolutionized education for the better in DC: for both types of schools, there remains a very strong, negative correlation between the percentages of kids At Risk and ‘pass’ rates on the DC-CAS.

Note that most schools have between 200 and 500 students and that most of the ones that are smaller are actually charter schools. As I wrote a couple of days ago, the schools with the largest fraction of At-Risk students (say, over 2/3 of the student body) are almost all regular DC public schools.

On the second graph, which is otherwise identical to the first, I’ve labeled some of the larger schools.

fixed bicolor, size of school and at risk vs average dc cas 2014 proficiency, both regular public and charter, dc

Here is the one with names of some of the larger schools, so you can see how individual schools fall on this graph.

(Sorry, I there was not enough room to label every single one, and my non-existent HTML skills won’t allow me to make it so that any of the dots are clickable. If any of my readers know how to do that and would like to offer to make that happen, then please let me know in the comments.)

again fixed and revised names and bicolor, size of school and at risk vs average dc cas 2014 proficiency, both regular public and charter, dc

And here is the entire data table. So you can see where every single school lies on these three dimensions.

(PS: I added a few more names of schools and corrected four other small errors, two pointed out by an alert reader.. 2/22/2015)

How Well are Charter Schools in DC Educating Students Who are Officially At-Risk?

The results may surprise you.

To answer this question, I used some recent data. I just found out that the DC City Council has begun requiring that schools enumerate the number of students who are officially At-Risk. They define this as students who are

“homeless, in the District’s foster care system, qualify for Temporary Assistance for Needy Families (TANF) or the Supplemental Nutrition Assistance Program (SNAP), or high school students that are one year older, or more, than the expected age for the grade in which the students are enrolled.” (That last group is high school students who have been held back at least one time at some point in their school career.)

So, it’s a simple (but tedious) affair for me to plot the percentage of such at risk students, at each of the roughly 200 publicly-funded schools in Washington, DC, versus the average percentage of students who were proficient or advanced in math and reading on the 2014 DC-CAS.

I was rather shocked by the results. Here are my main conclusions:

1. For almost all of the schools, to get a rough idea of the percent of students passing the DC-CAS, simply subtract 90% minus the number of students ‘At-Risk’. The correlation is very, very strong.

2. There are only THREE DC charter schools with 70% or more of their students At-Risk, whereas there are THIRTY-ONE such regular public schools. So much for the idea that the charter schools would do a better job of educating the hardest-to-reach students (the homeless, those on food stamps, those who have already failed one or more grades, etc).

3. The only schools that have more than 90% of their students ‘passing’ the DC-CAS standardized tests remain, to this day, the small handful of schools in relatively-affluent upper Northwest DC with relatively high percentages of white and Asian students..(Unless you include Sharpe Health school, where students who cannot feed or dress themselves or hold a pencil are somehow deemed ‘proficient’ or ‘advanced’ by methods I can only guess at…)

4. As I’ve indicated before, it appears that for the most part, DC’s charter schools are mostly enrolling smaller percentages of At-Risk, high-poverty students but higher fractions of the students in the middle of the wealth/family-cohesion spectrum than the regular DC public schools. There are a few exceptions among the charter schools: BASIS, Yu Ying, Washington Latin and a few others are succeeding in attracting families and students at the high end of the socio-economic and academic scales.

5. It looks like we are now turning into a tripartite school system: one for affluent and well-educated familes (relatively high fractions of whites and Asians; mostly but not all in regular Ward 3 public schools); one for those in the middle (mostly blacks and hispanics, many enrolled in charter schools), and one for those at the seriously low end of the socio-economic spectrum, overwhelmingly African-American, largely At Risk, and mostly in highly-segregated regular public schools.

Very, very sad.

Here is the graph that sums it all up. Click on it to see a larger version.

bicolor, at risk vs average dc cas 2014 proficiency, both regular public and charter, dc

In blue we have the regular public schools of Washington DC for which I have DC-CAS data for 2014, from grades 3 through 8 and grade 10. In red we have the privately-run but publicly-funded charter schools. Along the horizontal axis, we have the percentage of students who are officially At Risk as defined by the DC CIty Council. Along the vertical axis, we have the average percentage of students who scored ‘proficient’ or ‘advanced’ in math and reading on the DC-CAS at those schools. The green line is the line of best fit as calculated by Excel. Notice that the data points pretty much follow that green line, slanting down and to the right.

To nobody’s surprise, at both the charter and regular public schools, on the whole, the greater the percentage of students at a school who are At Risk, the smaller the percentage of students who ‘pass’ the DC-CAS standardized tests.

The colors do help us see that at the far right-hand end of the graph, there are lots of blue dots and only a small number of red ones. This means that the vast majority of schools with high percentages of At Risk students are regular DC public schools. You could interpret that to mean that parents in more stable families in those neighborhoods are fleeing from what they see as the bad influence of potential classmates who are extremely poor, homeless, have already repeated a grade, and so on, and are flocking to charter schools who have the freedom to expel or ‘counsel out’ such students and to impose a relatively strict behavior code that the DC Council forbids the regular public schools from using. (Their latest initiative is to forbit ALL out-of-school suspensions, no matter what…)

Dots that are above the slanted green line supposedly represent schools that are doing a better job at teaching to the tests than would be predicted by the At-Risk status alone. Dots below the line are doing a worse job than would be predicted. Notice that there are dots of both colors both above and below the line.

=====

I wish to thank the indefatigable Mary Levy for collecting and passing on this data. You can find the original data source at the OSSE website, but I’ve saved the larger table (all 2008-2014 DC-CAS data) on Google Drive at this link. I took the average of the percentage of students ‘passing’ the DC-CAS in math and in reading as the proficiency rate. The note on the at-risk data table reads as follows:

Data Source: SY2013-14 student-level data from OSSE. The list includes DCPS traditional, DCPS citywide specialized, DCPS selective schools, and public charter schools, but excludes any DCPS or public charter adult education or alternative school. The definition of at risk students includes students who are homeless, in the District’s foster care system, qualify for Temporary Assistance for Needy Families (TANF) or the Supplemental Nutrition Assistance Program (SNAP), or high school students that are one year older, or more, than the expected age for the grade in which the students are enrolled.

The Real Lesson of Singapore Math!

By now you’ve probably heard that Singapore and Shanghai are the two places on earth with the smartest kids in the entire world. We can see their PISA scores (go to page 5) are right at the top.

Case closed, right? Whatever they are doing in education, we in the US need to emulate that in order to catch up! Common Core! StudentsFirst! Teach for America! Race to the Top! PARCC! Bust those teacher unions! No more recess! All test prep all the time! Charter Schools! Turn the schools over to the billionaires (Gates, Bloomberg, Koch family, Walton family, and their hirelings and shills)!

But wait a second.

Have you noticed that an ENORMOUS fraction of the low-skilled, low-paid people living in Singapore are temporary foreign workers from various parts of Asia and Africa and are not allowed to bring their kids with them? Those kids are raised back in the workers’ homelands by various relatives, far away, and only get to see their parents at long intervals (somebody has to fly somewhere); back home, jobs are even scarcer and worse-paid, so the parents go elsewhere to try support their families.

Now, everywhere in the world, family income is very, very closely linked to children’s test scores in school. It’s one of the tightest correlations there are in the social sciences, as you can see in the simple scatter-plots I have repeatedly shown in this blog over the past 4 or 5 years. (Try using terms like “poverty” “income” and “scores” together in the search box on this page and be prepared to look through a lot of posts with such graphs, from all over!)

If one-quarter to one-third of the population of a country was legally not permitted to have children in the schools, and it was the low-paying 1/4 to 1/3 of the population, then the scores of the remainder of the kids would, quite naturally, be pretty darned good, since the bottom 1/4 to 1/3 of the distribution just got cut off.

If we systematically excluded the poorest quarter or third of our American student population from taking PISA, we know that our scores would be pretty darned high as well.*

Hmm, maybe the leaning tower of PISA hype is falling.

 

=====================

*Let’s remember that this WAS official policy in many states of the USA up until 1865: a large fraction of the population (guess which one!) was forbidden to send their kids to schools at all and it was explicitly forbidden even to teach them to read privately. When Jim Crow was established from the 1870s to the early 1960s, school facilities for Blacks and Hispanics, BY DESIGN of the racist authorities, so inferior to those for whites that they were a national disgrace. Which is why the calls for going back to the good old days should be so infuriating. There WERE NO GOOD OLD DAYS.

What I actually had time to say …

Since I had to abbreviate my remarks, here is what I actually said:

I am Guy Brandenburg, retired DCPS mathematics teacher.

To depart from my text, I want to start by proposing a solution: look hard at the collaborative assessment model being used a few miles away in Montgomery County [MD] and follow the advice of Edwards Deming.

Even though I personally retired before [the establishment of the] IMPACT [teacher evaluation system], I want to use statistics and graphs to show that the Value-Added measurements that are used to evaluate teachers are unreliable, invalid, and do not help teachers improve instruction. To the contrary: IVA measurements are driving a number of excellent, veteran teachers to resign or be fired from DCPS to go elsewhere.

Celebrated mathematician John Ewing says that VAM is “mathematical intimidation” and a “modern, mathematical version of the Emperor’s New Clothes.”

I agree.

One of my colleagues was able to pry the value-added formula [used in DC] from [DC data honcho] Jason Kamras after SIX MONTHS of back-and-forth emails. [Here it is:]

value added formula for dcps - in mathtype format

One problem with that formula is that nobody outside a small group of highly-paid consultants has any idea what are the values of any of those variables.

In not a single case has the [DCPS] Office of Data and Accountability sat down with a teacher and explained, in detail, exactly how a teacher’s score is calculated, student by student and class by class.

Nor has that office shared that data with the Washington Teachers’ Union.

I would ask you, Mr. Catania, to ask the Office of Data and Accountability to share with the WTU all IMPACT scores for every single teacher, including all the sub-scores, for every single class a teacher has.

Now let’s look at some statistics.

My first graph is completely random data points that I had Excel make up for me [and plot as x-y pairs].

pic 3 - completely random points

Notice that even though these are completely random, Excel still found a small correlation: r-squared was about 0.08 and r was about 29%.

Now let’s look at a very strong case of negative correlation in the real world: poverty rates and student achievement in Nebraska:

pic  4 - nebraska poverty vs achievement

The next graph is for the same sort of thing in Wisconsin:

pic 5 - wisconsin poverty vs achievement

Again, quite a strong correlation, just as we see here in Washington, DC:

pic 6 - poverty vs proficiency in DC

Now, how about those Value-Added scores? Do they correlate with classroom observations?

Mostly, we don’t know, because the data is kept secret. However, someone leaked to me the IVA and classroom observation scores for [DCPS in] SY 2009-10, and I plotted them [as you can see below].

pic 7 - VAM versus TLF in DC IMPACT 2009-10

I would say this looks pretty much no correlation at all. It certainly gives teachers no assistance on what to improve in order to help their students learn better.

And how stable are Value-Added measurements [in DCPS] over time? Unfortunately, since DCPS keeps all the data hidden, we don’t know how stable these scores are here. However, the New York Times leaked the value-added data for NYC teachers for several years, and we can look at those scores to [find out]. Here is one such graph [showing how the same teachers, in the same schools, scored in 2008-9 versus 2009-10]:

pic 8 - value added for 2 successive years Rubenstein NYC

That is very close to random.

How about teachers who teach the same subject to two different grade levels, say, fourth-grade math and fifth-grade math? Again, random points:

pic 9 - VAM for same subject different grades NYC rubenstein

One last point:

Mayor Gray and chancellors Henderson and Rhee all claim that education in DC only started improving after mayoral control of the schools, starting in 2007. Look for yourself [in the next two graphs].

pic 11 - naep 8th grade math avge scale scores since 1990 many states incl dc

 

pic 12 naep 4th grade reading scale scores since 1993 many states incl dc

Notice that gains began almost 20 years ago, long before mayoral control or chancellors Rhee and Henderson, long before IMPACT.

To repeat, I suggest that we throw out IMPACT and look hard at the ideas of Edwards Deming and the assessment models used in Montgomery County.

Poverty Isn’t Destiny?

Quite a few Ed Deformers say that Poverty Isn’t Destiny. They say that it doesn’t matter if a child has been subjected to lead poisoning, separation from parents, violent or otherwise cruel child abuse, inadequate nutrition, and has lacked dental or health care and the love and care of a family during the first, crucial years. All it takes is for a Bright Young Thing fresh out of college to work her butt off for two years before she goes to work for a bank — and all of those handicaps will be overcome, with no extra dollars invested, and maybe even less!

Or maybe not.

Lots of teachers have been working their butts off for many decades, doing their best, believe it or not (for the most part).

Here are two three graphs from Wisconsin that show how close the connection between the poverty rates and student achievement levels, at all of their schools for which they provide data. My data come from here and are for SY 2011-2012. In fact, you can download the entire spreadsheet for the state of Wisconsin if you click on this link:

http:reportcards.dpi.wi.gov/files/reportcards/xls/2011-12reportcarddata.xlsx

In both all three graphs, the percentage of students at the schools is along the horizontal (X) axis. In the first two, the average achievement score at the school is along the vertical (Y) axis.

In this first graph, Wisconsin uses a 100-point scale for overall student achievement.

wisconsin school overall student ach score by pct of poor kids

That is an incredibly strong correlation between poverty levels and student achievement. The fewer the proportion of poor students at a school, the better the achievement scores at that school.

I had Excel compute two correlation “trend” lines – one straight, in black, and one curved, in red following a third-degree polynomial, since it looks like we have a serious “Matthew effect” going on here. In either case, the R-squared and R values are very elevated, showing that, in fact, poverty is in fact destiny for a lot of kids.

The next graph is for reading only, but it shows essentially the same trend. School reading scores go from 0 to 50.

Wisconsin school READING scores by pct of poor kids

There are very few real-life correlations between two entities stronger than what you see in these two graphs.

This next graph is a little different, for two reasons: the y-axis is math, and it’s the percent of students deemed ‘proficient’ on whatever test Wisconsin is using. It also shows a very strong correlation.
