A visit to the PARCC

The PARCC (Partnership for Assessment of Readiness for College and Careers) test scores are coming in, and it ain't pretty.

PARCC is part of the whole Common Core, Test-Students-Till-They-Drop system that upper level educational administration seems so fond of lately.  I'll admit that the basic idea -- to provide all children with a common set of educational standards, and assess them all the same way -- sounds good.  Few could argue with a drive to raise standards, improve literacy, increase deep understanding of math.  In fact, part of its mission statement is, "PARCC helps ensure that all students, regardless of income, family background or geography, have equal access to a world-class education that will prepare them for success after high school in college and/or careers...  set(s) consistent expectations in English and mathematics for every student, and... provides a valid and reliable evaluation of each student’s progress toward them."

Sounds awesome, doesn't it?

But for an educational movement that comes out of a drive for equity and accountability, the implementation of these high-flying goals has been haphazard, and the assessments themselves are riddled with flaws.  The roll-out of new standards was rushed, leaving many teachers without adequate training and materials to deliver a completely new curriculum, and the end-of-year exams have been poorly aligned with curriculum expectations and, in some cases, at difficulty levels that are completely grade-level inappropriate.

This hasn't stopped the anti-public-school movement from treating those scores as if they were actually reliable.  The PARCC data for the state of Illinois were just released last week, and showed a considerable drop in average scores from previous assessments, prompting claims of incompetence against teachers and local administrators, withering criticisms of unions for protecting inadequate faculty members, and calls for defunding public schools and replacing them with charter schools and voucher systems.  It also prompted one Illinois teacher to write a concise list of the flaws in PARCC exams, which include the following:
  • giving children exams on computers in schools that don't have functional computer labs for kids to practice on
  • requiring all students to type their answers, thus adding "typing speed" as an unspoken parameter for success on the test
  • vague standards that are assessed by highly specific exam questions, leaving teachers uncertain about the depth to which they are supposed to address concepts
  • a "formative evaluation" on 75% of the standards, given 3/4 of the way through the school year -- but no information about which 75% of the standards would be tested
  • no scores released on the formative evaluation until after the school year ended and students had taken the final ("summative") assessment, leaving one wondering who the scores were supposed to be "formative" for
And need I add that the scores on these flawed exams are being used not only to evaluate children, but to evaluate teachers, administrators, schools, and entire districts?

You know who stands to gain here?  Pearson Education, who holds the extremely lucrative contract for designing all the exams, pre-tests, practice tests, review materials, and curriculum guides.  States are spending millions of taxpayer dollars to purchase a framework for assessment that, to put it bluntly, does not work, and then using that framework as a weapon with which to destroy public schools.

It's not just the teachers who are beginning to realize this.  Some institutions are recognizing the inherent flaws in the design and administration of standardized tests -- and are rebelling against the stranglehold they have over the educational system.  Hampshire College, in Amherst, Massachusetts, chose last year to stop accepting SAT and ACT scores from applicants; its president, Jonathan Lash, stated outright that "standardized test scores do not predict... student success" and that "multiple-choice tests don't reveal much about a student."

US News & World Report, which each year releases its rankings of US colleges and universities, retaliated by deleting Hampshire from its rankings.  Lash reacted with a shoulder shrug: "We surveyed our students and learned not one of them had considered rankings when choosing to apply to colleges," Lash said.  "Instead they most cared about a college’s mission... At college fairs and information sessions, we don’t spend time answering high school families’ questions about our ranking and test score 'cut-offs.'  Instead we have conversations about the things that matter: What does our unique academic program look like, and what qualities does a student need to be successful at it?"

Lash said that the experiment thus far has been an unqualified success:
Without the scores, every other detail of the student’s application became more vivid. Their academic record over four years, letters of recommendation, essays, in-person interviews, and the optional creative supplements gave us a more complete portrait than we had seen before. Applicants gave more attention to their applications, including the optional components, putting us in a much better position to predict their likelihood of success here.
I have some hope that these sorts of decisions are indicators of a coming sea change in our attitudes towards paper-and-pencil exams.  But we have a long way to go.  PARCC and the Common Core aren't going anywhere soon; Pearson Education, and people like Secretary of Education Arne Duncan (who famously stated that the only people critical of Common Core exams were "white suburban moms who are upset because they have discovered that their kids aren't as brilliant as they thought") are still pushing flawed assessments down our throats, along with all of the other outcomes -- loss of diversity in curriculum, loss of teacher autonomy in curriculum design and implementation, and a drastic increase in anxiety over testing in the children themselves.

So the fight's not over, not by a longshot.  I can guarantee that the failing scores on PARCC assessments in Illinois are not going to lead any of the powers-that-be to come to the conclusion that it's the assessment itself that is at fault.  They have too much at stake, both philosophically and financially, to reverse course that easily.  

So the power is in the hands of the parents, which is why it is so critical that the opt-out movement not lose its momentum.

I'll end with a repeated call for action: opt your children right the hell out of all of the state-mandated standardized grade-level exams -- at least the ones that have no impact on your child's passing a course (which, honestly, is most of them).  Keep them home.  Give Pearson no data to work with.  State departments of education have made unilateral bad decisions about how to assess your children, and it's time to take the control of education back to the local level -- where it should be.

Time to vote with your feet.

Knowing the score

One of the beautiful things about science is that it self-corrects.

If the data don't support the prevailing theory, you double-check the data to make sure you're not misinterpreting it, re-run the experiments to make sure they're well controlled, and then if you get the same results...

... you alter your model.

You have no other option.  Science is a method for understanding the world based upon logic and evidence.  If you accept that as a protocol for knowing the universe, you are dedicating yourself to following where it leads, even if you don't like the conclusions sometimes.

A pity, isn't it, that we can't introduce this approach into other fields?

Like, for example, education.  I'm a hard-core linguistics geek; in fact, my master's degree is in Scandinavian linguistics.  (Yes, I know, I teach biology.  It's a long story.)  So one of the things that galls me about education is the fact that we've known for decades that children learn languages better, more easily, and become more fluent the earlier you start them.  Kids put into language immersion classes in preschool learn a second language nearly as easily as the first, without tedious memorization of vocabulary lists and conjugations.

And when do most school districts begin language classes?  Middle school.  Right around the time kids' brains start getting bad at learning languages.

We don't need no scholarly research, educational leaders seem to be saying.  We've done it this way for years, and it's working just fine.

So with that scientific-method approach to analysis in mind, let's look at a piece of research regarding the current fad -- high-stakes standardized tests, now being used to evaluate not only students, but teachers, schools, and entire school districts.

Christopher Tienken, associate professor of Education Administration at Seton Hall University, has just published an interesting, and disturbing, paper in the Journal of Scholarship and Practice.  In it, he shows that he can predict how a school population will perform on standardized tests, using only U.S. Census data.

You read that right.  Give Tienken information on demographics, ethnic makeup, socioeconomic status, community size, and so on, he can tell you how the school will do on standardized tests before the students actually take them.  Tienken writes:
In all, our regression models begin with about 18-21 different indicators.  We clean the models and usually end up with 2-4 indicators that demonstrate the greatest predictive power.  Then we enter those indicators into an algorithm that most fourth-graders, with an understanding of order or operations, could construct and calculate. Not complicated stuff.

Our initial work at the 3rd-8th and 11th grade levels in NJ, and grades 3-8 in CT and Iowa have proven fairly accurate.  Our prediction accuracy ranges from 62% to over 80% of districts in a state, depending on the grade level and subject tested.
I hope you recognize how devastating this is to the claim that standardized tests tell you anything worth knowing about teacher competence.  If census data alone predicts student performance, then how are "underperforming" teachers supposed to improve their scores?  Tienken's research implies that poor teachers will suddenly become more competent... if they move to a different district.

Tienken doesn't mince words about the implications of his study:
The findings from these and other studies raise some serious questions about using results from state standardized tests to rank schools or compare them to other schools in terms of standardized test performance.  Our forthcoming results from a series of school level studies at the middle school level produced similar results and raise questions about the appropriateness of using state test results to rank or evaluate teachers or make any potentially life-impacting decisions about educators or children.
Now, Tienken isn't saying that teachers make no difference; we all, I think, can attest to the power of a truly skilled teacher in making a difference to a child's life.  I had three teachers who stand out as having turned the course of my life in some way -- my high school biology and creative writing teachers, and my first-year college calculus teacher.  Each of them engendered in me a passion for learning and a fascination with the topic, such that I looked forward to each and every class and wanted more when I was done.

But the point is, this sort of thing is not measurable with a standardized test.  The real value of truly gifted teachers is their capacity for making learning relevant and engaging, making dry academic subjects come to life.  And whatever standardized tests are measuring -- a point no one, even the policy wonks at the state and federal Departments of Education, seems to be entirely clear on -- they certainly don't measure that.

So teacher evaluation, astonishingly enough, is best done by a competent administrator, who knows the teacher, the subject, and the students, not by some paper-and-pencil exam.  Who'd'a thought.

And it'd be nice if the people in charge would look at Tienken's research, and do a forehead smack, and say, "Wow!  We were wrong!  Better reconsider how we're applying standardized test scores!"  But given that scientific rules of validity and analysis don't seem to apply to education, I have the feeling that the result of Tienken's study will be: nothing.  We will almost certainly keep moving down the same road, letting test scores drive more and more decision-making, up to and including teacher salaries and retention.

Can't let a little thing like facts get in the way of educational reform, after all.

The Common Core product placement conspiracy

I've been asked, at times, if I think it's possible that some conspiracy theories may be true.

And my answer is: of course.  Humans conspire.  It's the evil side of being a social animal; we sometimes use our social proclivities for immoral reasons.  So clearly there are some cases where "conspiracy theory" is actually "conspiracy fact."

It's just that I don't think most of the best-known ones -- the 9/11 inside job/controlled demolition claim, the Sandy Hook crisis actors claim, the HAARP weather modification claim -- have a scrap of evidence in their favor.  But other ones?  They have to be evaluated on their own merits, or lack thereof.

This comes up because I ran into a story yesterday that has all of the hallmarks of a conspiracy -- and yet I find it entirely believable.  I will say up front that I have no hard evidence that my claim is true.  It may be that what occurred here was entirely innocent, and the individuals involved are being straightforward and aboveboard.

But my opinion is that this stinks to high heaven.

I found the article because I was doing some reading about the latest on the Common Core, the ill-conceived and poorly-executed fad of the month for fixing public education by administering more standardized tests.  Oh, the standards themselves look okay: more understanding of math holistically, with less focus on minute details of symbol manipulation; more reading from source materials and writing to express understanding.  But the way it has been implemented has been haphazard at best, with an emphasis on test preparation, leading up to nationally-administered exams that put millions of dollars in the pockets of corporations like Pearson Education.

There has been a groundswell of anger about the whole thing, not only from teachers and administrators, but from parents.  This has led to a growing opt-out-of-the-tests movement, which is gaining traction across the country.  Oh, the fourth grade reading exam is tomorrow?  I'm sorry, my son is sick.  The make-up exam is in three weeks?  Oh, darn, I'm sorry.  He's going to be sick then, too.


But right here in my home state of New York, there's been a revelation of an even darker side of the whole thing.  A story in the Syracuse Post-Standard ran a few days ago that described the fact that the Common Core exams, provided by Pearson, include multiple examples of...

... product placement.

Yes, you read that right.  This has gotten out despite Pearson's tight control on the exam content -- teachers and students are expressly forbidden to reveal, much less copy and distribute, test materials, even once the test has been administered.  But you can't keep something this egregious a secret.  So the 3rd through 8th grade assessments were barely collected and scored when it came out that Barbie, Nike, iPod, Life Savers, and Mug Root Beer had all made their way into the exams.

And not in subtle ways, either.  The Nike brand and slogan appeared in a paragraph about risk-taking.  A story about a busboy cleaning up a root beer spill was specified as cleaning up Mug (a trademark owned by PepsiCo).  They weren't even taking the trouble to hide the product placement, the way that television sitcoms do -- such as placing a two liter bottle of Coca-Cola on a counter in the background of a scene.  This was blatant.

Everyone involved, of course, has denied that Pearson is receiving kickbacks from the corporations that produce the products mentioned.  "There are no product placement deals between us, Pearson or anyone else," Tom Dunn, an Education Department spokesman, said in an interview on Fox News. "No deals.  No money.  We use authentic texts.  If the author chose to use a brand name in the original, we don’t edit."

Mmm-hmm.  And if several of those texts mention products from multi-million dollar corporations, that's purely a coincidence.

Right.

The growing influence of corporations on education is a horrifying trend.  Kevin Kumashiro, writing for the American Association of University Professors, writes:
Current reforms are allowing certain individuals with neither scholarly nor practical expertise in education to exert significant influence over educational policy for communities and children other than their own.  They, the millionaires and billionaires from the philanthropic and corporate sectors, are experimenting in urban school districts with educational reform initiatives that are not grounded in sound research and often fail to produce results.  And yet, with funding for public education shrinking, the influence of these wealthy reformers is growing...  The result is a philanthropic sector that is inseparable from the business sector, advancing school reforms that cannot help but to be framed by corporate profitability.
And that's just it, isn't it?  The corporate leaders are not specialists in education; they have never been teachers, administrators, served on school boards.  It is just that by virtue of the money they have, they feel entitled to direct educational policy.  And the sad fact is, because of the increasing desperation of school districts to stay afloat financially, the corporations are succeeding.  More and more, state educational systems are making deals with the devil, and sacrificing our children as a consequence.

So could the appearance of product placement in Common Core-based exams be an accident, a result of random choice of textual material that mentioned modern corporate products that are appealing to children?  Could it have nothing to do with the ongoing attack on the public school system by special interest groups and money-hungry boards of directors?  Could Tom Dunn have been telling the truth when he said that Pearson got nothing for their blatant product placement?

Sure.  It could be.

But I don't believe it for a moment.
