a palisadesk post

I don't remember now, but I think palisadesk may have been writing comments on kitchen table math from the beginning.

I do remember my first impression: WOW.

This person knows what he/she is talking about.

My first impression was right. In all these years, I don't think I've ever seen palisadesk stray from the mark.

So when Surfer got sick, and palisadesk turned out to have saved a dog with mast cell cancer^* (it would be palisadesk, wouldn't it?)......I was initially thinking 'vegan' and then palisadesk weighed in with her quasi-ketogenic^** approach to treating mast cell cancer via diet.....

.....And a few weeks into the whole business, contemplating my growing collection of resources on dog cancer, Kinvaet, mast cell cancer, obesity as a precursor and possible cause of mast cell cancer, diet, etc, etc......it occurred to me that my best best was just to do whatever palisadesk did and call it a day.

And that's pretty much what I did.

At this moment, Surfer is better than I've seen him in a long time. He's frisky; he's acting like a much younger dog. And he's turning 12.

Surfer may yet die of mast cell cancer, of course. Just a moment ago he walked past me and I spotted a new bump on his side. That's been another fun part of the mast cell adventure: Surfer sprouts lypomas on a monthly basis, and I can't tell the difference between a lypoma and a mast cell tumor. So I spend a lot of time palpating new growths (and old growths I can't remember whether I've seen before): a bad idea because palpating a mast cell tumor can cause it to "degranulate," sending the dog into an instantaneous and fatal case of anaphylactic shock. I have been specifically warned not to be palpating growths.

I'm sure palisadesk would say Don't do that.

Anyway, as I say, Surfer may yet die of mast cell cancer.

But if he does, my view of palisadesk's advice won't change. Mean survival time for surgical treatment alone, without chemo, is 18 weeks. (Mean time from diagnosis? from date of surgery? Nobody ever seems to say.) Surfer had his surgery February 4, and I'm pretty sure he developed the tumor in early January. (The vet found the tumor during a routine check-up.)

So it's 12 weeks since the surgery, a good 16 weeks since the tumor appeared, and the Kinavet didn't work out. And Surfer is not on his last legs.

I may be tempting fate, writing that.

But that's fine.

[pause]

Hmmm.

I'm listening to the YouTube discussion of Kinavet. You're supposed to wear gloves to pick up a Kinavet pill your dog has spit out.

How many Kinavet pills did Surfer spit out?

And how many did I pick up with my bare hands?^***

A lot.

Oh, well.

This may be one of the best review articles I've seen: Clinical Management of Mast Cell Tumors in Dogs

^* The dog is still alive today, 10 years later.
^**or really ketogenic - I don't want to put words into palisadesk's mouth
^*** I could not get pills down Surfer's throat wearing gloves. I tried. I didn't know the bit about "the seal being broken" once the pill has been spit out, however.

Home stretch! back soon--

Down to the last 100 pages of Debbie's book, which is fantastic.

So still no blogging, but ----- I have bullet points!

• The tuna cure: Surfer and Abby now eat tuna, lentils, and olive oil (plus, starting in the past week, a few carrots). Basically: a low-rent version of palisadesk's high-protein diet for mast cell cancer in dogs. Surfer--who, it turns out, can't tolerate chemo--appears to be fine. (But we'll see.) The younger vet told me mast cell cancer is the dog equivalent of pancreatic cancer: Surfer, with a Stage 3 diagnosis, was a goner unless the Kinavet worked. Older vet, back now from his own brush with death, says: "It's not a death sentence." (Ed says: Can we always see the older vet?) Funnily enough, we encountered the same division of labor during the two years my mother was sick. The younger doctors would waylay my siblings and me for The Talk (Your mother is dying. Let her die with dignity. If she doesn't want to die with dignity, persuade her.) Then the older docs would say things like "In intensive care we support your mother's organs until her body is strong enough to handle those functions again." The older docs were always right. And they never mentioned death with dignity, which was wise because my mother didn't give two figs for dignity.

• New high school principal for Irvington who worked for TFA

One board member told me that when the board met the new principal he must have used the word accountability in every other sentence.

Are we the first affluent district ever to hire a TFA person?

We may be. A TFA alum certainly seems out of place here in Westchester, where affluent districts are snapping up superintendents fleeing New Jersey's salary cap.

Our new super replaces the superintendent against whom a number of us waged a running battle for 5 long years (or was it 6?). He is a man in his late 30s or early 40s, trained in elementary education, whose only previous experience--in New Jersey, where his wife and son continue to live--was heading a tiny K-5 district.

We are paying him $250K per year on a 5-year contract. During a minor depression.^* (Did I mention I'm voting no on the budget?)

I think it's possible, perhaps likely, the TFA hire would not have happened without 6 years of citizens' op eds on the Irvington Parents Forum.

Ed told me, when I started the Forum, that revolutions always have writers.

I believe him, and All revolutions have writers has been my essential reason for carrying on. Well, one of the essential reasons, the other essential reason being that both sides of my family came from Ulster.

That said, I don't expect a revolution. The new superintendent has thus far been more of the same, and he was supposed to be The One; all 5 board members said so. The new principal will come into a gatekeeping culture that has been in place for many, many years.

The single best observation anyone ever made to me concerning my district's unshakeable self-regard:

...[W]e're great because 10 kids do spectacular things by senior year. The other 150 will get by and there are no glaring inadequacies.

That's not going to be easy to change.

Holistic College Admissions

I'll scream if I hear the word "holistic" at a college info session again. What it really means is that the admissions people love their own sensibilities and power. This might be fine if the choice was between two applicants for one open slot, but it's now a choice between 5 or 10 applicants at some colleges. They claim that there is no merit function that they use, but they don't tell you that the intangible factor has now risen to well over 50 percent of the admissions judgment. Since so many students meet some basic level of ability to handle the rigor at the college, one application out of 5 or 10 is selected based on the judgment of admissions people. They don't even turn some of their holistic decisions over to individual departments that know about academic content. They can't tell whether an applicant is at a base camp or a mountain top.

The admissions judgments are based on essays, recommendation letters, and character intangibles rather than academic intangibles. The admissions person we saw yesterday talked about their criteria of whether you would be an interesting person to have a cup of coffee with. They claim that they can see right through all applicants to tell if they are "authentic", "genuine", and "consistent". I think it just means that you have to be less authentic and hire better admissions prep people. They tell us that the essay and letters of recommendation are critical, but do they really think that the people they select did not get professional help? Sure, they can see through some applications, but what about the difference between authentic students who get help and authentic students who do not?

The other problem is that admissions people seem so anti-math and science. I'll scream a second time if I hear another admissions person or tour student tell us that the general education requirements allows you to not have to take another real math class; that there are other classes that will fulfill the requirements (ha ha). These are Ivy League schools. So here is this engaging English major tour guide who appeals to admissions more than a bookish math student who might have qualified for the AIME test.

We talked with a professor of music who said that they don't get audio portfolios of students to evaluate unless there is a final tie-breaking issue. He was having trouble getting a chance to evaluate and comment on an applicant who was a Presidential Scholar in the Arts. The holistic intangibles are closely held by the admissions people. It's OK, however, to select applicants who are clearly at the top of their math career. Then again, the admissions people may not know the difference.

Making it as a Middle School Teacher

I find this joke much funnier coming from a kid, I have to say.

This one's funny, though: Should I ask the teacher my question?

The tragedy of histogeomegraph continues

In the news today: another botched attempt at interdisciplinarity in our public schools:

ALBANY — High school is full of hypotheticals, like “How does one solve for x?” and “What happens if I skip class?” But this week, students at Albany High School were given an alarming thought puzzle: How do I convince my teacher that I think Jews are evil?

[snip]

“Your essay must be five paragraphs long, with an introduction, three body paragraphs containing your strongest arguments, and a conclusion,” the assignment read. “You do not have a choice in your position: you must argue that Jews are evil, and use solid rationale from government propaganda to convince me of your loyalty to the Third Reich!”

[snip]

Dr. Vanden Wyngaard, who met with Jewish leaders in Albany and made a public apology on Friday, said the assignment was apparently an attempt to link the English class with a history lesson on the Holocaust. The assignment itself seems to back up that theory, telling students to use “what you’ve learned in history class.” It also suggests using “any experiences you have.”

It echoed another recent, controversial assignment in Manhattan, where an elementary school class was given math problems featuring the whipping and killing of slaves, according to The Associated Press. That assignment was an effort to combine math and social studies lessons.

checking in--and decline and fall

I'm doing a very rushed polish of Debbie S's SAT book -- which is wonderful -- and we're around-the-clock, so no blogging!

But I'm amassing beaucoup SAT factoids, so I'll put some up as I go.

For starters, here are the basics on the 16-year decline in SAT scores:

• SAT scores declined from 1963 to 1980
• Verbal mean: dropped from 475 to 425
• Math mean: dropped from 500 to 470
• By 1990, the Math mean has gone back up to 475, but Verbal mean has not budged
• By 1980 College Board perceives a “definite need” to “realign the verbal and math scales”
• SAT V and SAT M averages are 50 points apart
• “there was a clear need to repopulate the top end of the score scale, especially for SAT V”

Essay-Grading Software Offers Professors a Break By JOHN MARKOFF
Published: April 4, 2013 | New York Times

I'm actually in favor of essay grading software, in theory. I've been interested in automated essay scoring ever since reading Richard Hudson's paper Measuring Maturity in Writing (which I need to re-read, so nothing more on that at the moment):

Abstract
The chapter reviews the anglophone research literature on the 'formal' differences (identifiable in terms of grammatical or lexical patterns) between relatively mature and relatively immature writing (where maturity can be defined in terms of independent characteristics including the writer's age and examiners' gradings of quality). The measures involve aspects of vocabulary as well as both broad and detailed patterns of syntax. In vocabulary, maturity correlates not only with familiar measures of lexical diversity, sophistication and density, but also with 'nouniness' (not to be confused with 'nominality'), the proportion of word tokens that are nouns. In syntax, it correlates not only with broad measures such as T-unit length and subordination (versus coordination), but also with the use of more specific patterns such as apposition. At present these measures are empirically grounded but have no satisfactory theoretical explanation, but we can be sure that the eventual explanation will involve mental growth in at least two areas: working memory capacity and knowledge of language.

Maturity of writing, in this sense, can be measured by software, and I would be using automated scoring software myself if I could buy essay-scoring software on Amazon. EdX says it's giving software away free to 'institutions' (does that leave out individuals?) so I'll have to see if my department might throw its hat in the ring.

That said, a lot of this is nonsense:

Anant Agarwal, an electrical engineer who is president of EdX, predicted that the instant-grading software would be a useful pedagogical tool, enabling students to take tests and write essays over and over and improve the quality of their answers. He said the technology would offer distinct advantages over the traditional classroom system, where students often wait days or weeks for grades.

[snip]

“It allows students to get immediate feedback on their work, so that learning turns into a game, with students naturally gravitating toward resubmitting the work until they get it right,” said Daphne Koller, a computer scientist and a founder of Coursera.

[snip]

“One of our focuses is to help kids learn how to think critically,” said Victor Vuchic, a program officer at the Hewlett Foundation. “It’s probably impossible to do that with multiple-choice tests. The challenge is that this requires human graders, and so they cost a lot more and they take a lot more time.”

None of these things is going to happen. Students aren't going to write essay responses "over and over again;" if they do write essay responses over and over again it's not going to feel like a fun game; and nobody's going to learn to think critically from automated essay scoring software.

Oy.

In honor of the latest bulletin from palisadesk, I've started a new Blogger page.

uh oh

A note from palisadesk:

Unfortunately, it is true that using Lucy Calkins' methods can raise test scores, due to the design of the current generation of "authentic assessments" (aka holistic assessment, standards-based assessment, performance assessment). I know several schools (including my own) where test scores rose substantially when they STOPPED doing systematic synthetic phonics and moved to a workshop model instead.

So to prove the instructivist stuff works you also need to have in place testing that assesses actual skills -- phonemic decoding, vocabulary, grammar, spelling, arithmetic, etc.

It's really not all that unbelievable, if you consider how the testing has 
changed. Schools used to use norm-referenced measures (like the IOWA, the
 CTBS, Metropolitan Achievement Test, etc.) which also have definite 
limitations, but different ones.

Once they replaced those (as many states
 have done) with "constructed-response" item tests, variously known as 
performance assessments, holistic assessments, standards-based assessments 
and so on, a more fuzzy teaching approach also yielded benefits. These 
open-response items are usually scored on a rubric basis, based on anchor 
papers or exemplars, according to certain criteria for reasoning,
 conventions of print, organization, and so forth. These are variously 
weighted, but specifics like sentence structure, spelling, grammar,
 paragraph structure etc. generally carry less weight than such things as
 "providing two details from the selection to support your argument."

The 
open responses often mimic journal writing -- it is personal in tone, 
calls for the student to express an opinion, and many elements of what we
 would call good writing (or correct reading) count for little or even 
nothing.



The same is true in math. A local very exclusive private school which is 
famous for its high academic achievement recently switched from 
traditional math to Everyday Math and saw its test scores soar on these assessments (probably not on norm-referenced measures, but they aren't
 saying).



Another school where I worked implemented good early reading instruction 
with a strong decoding base (and not minimizing good literature, either),
 but saw its scores on the tests go down almost 25%. I think the reason
 for that is that teaching children to write all this rubbish for the "holistic assessments" is very time consuming, and if you spent your 
instructional time teaching the basic skills -- which aren't of much value 
on these tests -- your kids will do poorly.



So yes, you can post [my email], not referring to me of course. You can say -- 
because I don't think I've mentioned it publicly anywhere -- that I have 
been involved in the past in field-testing these assessments so have a 
more complete picture of how they are put together and evaluated, and what 
they do and do not measure.

Different states have made up their own but 
they share many similarities.

I was surprised when I read this ..... somehow I had assumed that, basics being basic, absence of basics would make any test hard to pass.

Apparently not.

seeking Tiger Mom

At the WSJ (not sure whether it's behind a pay wall): "To (All) the Colleges That Rejected Me" by Suzy Lee Weiss.

Like me, millions of high-school seniors with sour grapes are asking themselves this week how they failed to get into the colleges of their dreams. It's simple: For years, they—we—were lied to.

Colleges tell you, "Just be yourself." That is great advice, as long as yourself has nine extracurriculars, six leadership positions, three varsity sports, killer SAT scores and two moms. Then by all means, be yourself! If you work at a local pizza shop and are the slowest person on the cross-country team, consider taking your business elsewhere.

What could I have done differently over the past years?

[snip]

Having a tiger mom helps, too. As the youngest of four daughters, I noticed long ago that my parents gave up on parenting me. It has been great in certain ways: Instead of "Be home by 11," it's "Don't wake us up when you come through the door, we're trying to sleep." But my parents also left me with a dearth of hobbies that make admissions committees salivate. I've never sat down at a piano, never plucked a violin. Karate lasted about a week and the swim team didn't last past the first lap. Why couldn't Amy Chua have adopted me as one of her cubs?

This girl is a fabulous writer!

ABSTRACT

This paper shows that although the top ten percent of colleges are substantially more selective now than they were 5 decades ago, most colleges are not more selective. Moreover, at least 50 percent of colleges are substantially less selective now than they were then. This paper demonstrates that competition for space--the number of students who wish to attend college growing faster than the number of spaces available--does not explain changing selectivity. The explanation is, instead, that the elasticity of a student's preference for a college with respect to its proximity to his home has fallen substantially over time and there has been a corresponding increase in the elasticity of his preference for a college with respect to its resources and peers. In other words, students used to attend a local college regardless of their abilities and its characteristics. Now, their choices are driven far less by distance and far more by a college's resources and student body. It is the consequent re-sorting of students among colleges that has, at once, caused selectivity to rise in a small number of colleges while simultaneously causing it to fall in other colleges. I show that the integration of the market for college education has had profound implications on the peers whom college students experience, the resources invested in their education, the tuition they pay, and the subsidies they enjoy. An important finding is that, even though tuition has been rising rapidly at the most selective schools, the deal students get there has arguably improved greatly. The result is that the "stakes" associated with admission to these colleges are much higher now than in the past.

Will let you know once I've skimmed the study....

What are standards for? What do they have to do with curriculum?

Q: Why do schools need standards? What are standards for? What do they have to do with curriculum?

A: A set of standards is a *minimum set of requirements* that a product must meet. Let's imagine a house; the building codes are standards. An individual standard says something like "a wall must withstand straight line winds of up to 75 mph" or "studs must be places at least every 24 inches." Standards tell *what* you need to do, but don't tell you how to do it. They are used so that in the event of a serious risk, the whole structure stays standing. The building code for homes applies whether building a tiny townhouse or a 5 bedroom multi-story rambler. They are meant to force people not to cut too many corners. Standards here in math education are similar: they tell you what must be taught to a student, when, year over year. They are still *minimum set of requirements*, the ones that need to apply to every classroom, every school, every student.

A set of building codes aren't plans for a building. They are not a complete design.

A design tells you what *this building* going to look like. It answers the question of what purpose this house serves. It shows you how the floors and rooms fit together, how space is utilized. Architectural plans are a design for a home. They explain what the floor plan is, what the foundation is shaped like, where the plumbing goes, where the electricity goes, how the building will maintain even temperatures, etc. It's a map for everything that needs to be built.  A solid design takes into account the what the end result should be like and plans the structure accordingly. A good design is also relatively easy to build, because it anticipates what elements of the design depend on the other elements.



In math education, this design is the curriculum. The curriculum is the plan for each year of math education, starting with a foundation, then the walls, the plumbing, the electrical, the floors, the roof, the interior. Like a good design for a building, a good curriculum is easy to implement, anticipating not just the end product, but how to ease the building of the elements as they are put in place.

A design is necessary for a home, but we don't live in an architectural drawing. The home must still be built So there are builders. Clearly the builders need to know the standards, and build according to them, so the structure is safe. But they build according to the standards while the build up the plan, starting with the foundation, and then moving on through the structure. They complete the plan.

Teachers are the builders. They are building the house of mathematics that students will live in. Some teachers are like builders who just doing the efficient thing, putting the pieces up in order. Others are like exquisite craftsmen. The most experienced teachers are like the most experienced builders who are able to look at the plans and figure out what won't quite work in this context, and where changes should be made. They know how long the job will take, and where the hard parts are before they start. They make very few mistakes, and correct them before they cause more problems. A great math teacher is building above and beyond the minimum standards where and when she can; she is on the lookout for the pitfalls in the curriculum, ready to point them out and rework them; she is improving her own skills, employing new innovations, and producing beautiful results.

Bad standards mean the structure is unsafe. Unfortunately, this isn't always visible to the eye. The owner may not find this out until a minor tremor comes and the whole house collapses. Likewise, a bad plan means the house is not a comfortable or useful place to live, or worse, could be dangerous. If the house was designed incorrectly, then the second story may not be able to hold up the third story, and it could collapse. A truly terrible design usually can't be rebuilt, but needs to be torn down. And a bad builder means things go wrong and break in your home, and again, if bad enough, the errors could mean that the house collapses. 

Likewise, in math education, bad standards means the whole structure of math that a student is building up is faulty, and sooner or later, it is going to collapse. But good standards aren't the same as a good design. Students themselves don't need to learn the standards, any more than a homeowner needs to know the building code. Schools need to have a design, a curriculum, for their teachers, the builders to work from. A bad design won't support another story being built on top, year after year after year. And a bad builder on a floor means nothing can be built on top of it until a great builder comes in and rips out the bad work and rebuilds.

Every part of the process matters. Good standards, good curriculum, good teachers.

MOOCs, the doomsday scenario

More from the Times on MOOCs:

That the acronym MOOCs rhymes with “nukes” seems apt. Massive open online courses, or MOOCs — led by two profit-making start-ups, Coursera and Udacity, founded by entrepreneurial Stanford professors — are a new disruptive force in education.

[snip]

The MOOC skeptics have a variety of qualms, but especially about what is lost in the retreat of face-to-face teaching — a point eloquently made by Andrew Delbanco, a professor of American studies at Columbia University, in an article in the current New Republic, “MOOCs of Hazard.”

Michael A. Cusumano, a professor at the Sloan School of Management at M.I.T., raises a different issue in an essay published this week: the economics of MOOCs and the implications.

His article appears in Communications of the ACM, the monthly magazine of the Association for Computing Machinery, and he had circulated a version of it earlier to his M.I.T. colleagues. After reading it, L. Rafael Rief, M.I.T.’s president, asked Mr. Cusumano to serve on a task force on the “residential university” of the future, including online initiatives.

“My fear is that we’re plunging forward with these massively free online education resources and we’re not thinking much about the economics,” Mr. Cusumano said in an interview.

The MOOC champions, Mr. Cusumano said, are well-intentioned people who “think it’s a social good to distribute education for free.”

But Mr. Cusumano questions that assumption. “Free is actually very elitist,” he said. The long-term future of university education along the MOOC path, he said, could be a “few large, well-off survivors” and a wasteland of casualties.

Mr. Cusumano’s concerns grow out of his study of the software and media industries in the face of price pressure from free, open-source software and digital distribution over the Internet. Two-thirds of the public companies in the software industry disappeared between 1998 and 2006, as companies failed or were acquired. In the media world, Mr. Cusumano contends that newspaper and magazine companies — including The New York Times Company — made a strategic mistake by giving away their publications free on the Web....

Give-away pricing in education, Mr. Cusumano warns, may well be a comparable misstep. The damage would occur, he writes in the article, “if increasing numbers of universities and colleges joined the free online education movement and set a new threshold price for the industry — zero — which becomes commonly accepted and difficult to undo.”

Beware of the High Cost of ‘Free’ Online Courses

"Massive open online courses, or MOOCs — led by two profit-making start-ups, Coursera and Udacity, founded by entrepreneurial Stanford professors — are a new disruptive force in education."

Really?

We have disruption now?

As far as I can tell, "creative disruption" is occurring when a new business is actually winning. MOOCs aren't a business, and they aren't winning, not at the moment.

And I don't recall distance learning being a disrupter back in the 1990s.

As far as I can tell, the only reason we're even talking about MOOCs is that we are 5 years into a depressed economy, and "free" is sounding like an awfully good idea right about now.

But as for disruption....I fear that the kind of disruption people seem to have in mind when they use the word already happened in the 1990s, and MOOCs are the least of it. Lots more administrators, lots fewer full-time professors, and now MOOCs. Swap in videos of Harvard professors, swap out the adjuncts. More for me!

I suppose you could characterize the bureaucratization of colleges and universities as creative disruption that benefits the administrators, but that's not what Clayton Christensen had in mind when he developed the concept.

Right, but.

People like music and news; people listen to music and read news instead of getting down to work.

College courses, on the other hand, are work. A college course is the activity you listen to music and read news to avoid. MOOCs are going to be hard to give away, not easy.

For most of the MOOC discussions I come across, executive function is the Great Unsaid. That, and the fact that Free is not a business model.

My brother showed me this video --- can't remember if we've ever posted it here.

What I love about it is that the girlfriend actually comes up with a guesstimate that's pretty close to correct, which reminded me of something I once read about the difference between really good math students versus the "works hard" variety.

To wit: the really good students devise elegant and efficient solutions and proofs. The 'works hard' students go on wild goose chases.

Works-hard students do get to the answer or the proof eventually, but the process isn't pretty. (Speaking as a person who has spent a lot of time teaching herself math, I relate.)

The process may not be pretty, but it can be funny.



Another thing: this exchange is a brilliant example of "inflexible knowledge" in action. The young woman isn't transferring the meaning of "per hour" to a different phrasing of the same situation.

Speaking of inflexible knowledge, in Atlantic City this weekend we had a semi-galling episode of Failure to Transfer. My father-in-law has been deaf for years, and Ed and I -- and Andrew -- have had iPads for at least two. We use Andrew's iPad to communicate with him via typing (Andrew types, too). Yet it had never occurred to us that we could do the same for Ed's dad.

Two years to make the connection!

Immediately after I'd had the blinding revelation that iPads work for old people with hearing loss as well as young people with autism, we began plotting and scheming how to get an iPad for Ed's dad (would he use it?? Which one should we get?? The big one?? The little one that would take up less space on a dinner table?? Etc.)

It took me a good 5 minutes to figure out that Ed's dad does not need an iPad. He can talk.

We had a chuckle over that & then an hour or so later Ed raised the subject again.

We have spent a LOT of years living with people who can't talk.

Today I'm trying to figure out if I'm on Spring Break. You'd think I'd know these things. (I'm tutoring in the Bronx this semester & don't know whether the Learning Center stays open during break.)

Back in a bit.

SAT Essay

My son is in the middle of preparing for his first (and hopefully only) official SAT test. He took the PSAT in the fall and did very well, so we do have some ideas of what to work on. However, the PSAT does not have an essay portion, so he is starting from scratch for that. I had him do the Blue Book essay for test 10, but I don't know how the scores are calibrated. Was it a 6, a 9, or a 12? How does one improve? Also, I was told that even professional writers might get 10's and not 12's. The problem is that there is way too much advice if you just search online.

Since I have used and liked Mike McClenathan's PWN the SAT book for math, I thought I would download his new Kindle "Essay Guide". Like his math book, it gets right to the point. (It's also so inexpensive that buying it is a no-brainer.) It uses a five-point star diagram to explain how there are five areas that one has to improve upon to get a better score:

1. Development and support of point of view

2. Organization and focus

3. Grammar, usage, and mechanics

4. Variety of sentence structure

5. Use of vocabulary

The document explains each of these and then talks about a general approach to writing the essay, starting with the body. OK. we are on the same wavelength. I've always thought that your examples will define your position. Of course, Mike goes into much greater detail, but he still keeps the document short.

One issue that I talked with Mike about was how, even with this information, some students might go backwards before they go forwards. He agreed that that can happen. I don't want to shove his document in front of my son and say: "Read this!" My goal is to see the big picture and focus on the things that will most likely improve my son's score. I'm more apt to show him parts of the document that will help him.

Mike's book does put this into perspective. Since it's so hard to improve from a score of 10 to 12, you will be better off improving on the multiple choice section. If you get all of those questions correct, you can perhaps get a '9' on the essay and still get an 800 score. If you get one wrong, then you need to get an '11' on the essay to get an 800. If you get two wrong and a '10', you could drop down to 760! This analysis can be extended to those not up at that lofty height, but you come up with a different answer. On BB test 1, if you get a raw score of 41 (about 7 wrong), the difference between an essay score of 8 and 9 changes your writing score from 630 to 660! At that level, it would be better to work on your writing rather than the multiple choice questions. And, as Mike points out: "Colleges you apply to might read your SAT essay."

So, my question was where is my son located on this map. I had to have some calibration for the multiple choice questions and the essay. His PSAT score told me about the multiple choice questions, but I needed to have some real feedback on his essay. I was told that robo-readers tend to give high scores. Some talk about getting 12's from them, but 10's from real people. Mike offered to give me real feedback for my son so that we would know where in the ballpark he was. I think this is a good process. Don't just dive in and work without knowing what to work on. It turns out that my son is in the '10' ballpark with no studying, so I will probably just pick and choose parts of Mike's document to show him. I think I will start with having him organize his experiences and references in terms of larger ideas, like morality, technology, and creativity. Then I will have him practice reading questions and determining his examples and position. The biggest risk for him is to read a question that stops him cold. Apparently, a "reality TV" question once did that for a lot of people. It would be tough to fit The Great Gatsby into that.

From all of this, I found out that my son does not need to spend as much time as I thought on the essay, and we know specifically what to work on. Now, where did we put Erica's grammar book? We are also waiting for pages 26+ in her new "The Critical Reader" book.

budget season

Sorry to be missing in action -- budget season is upon us, and I've been writing posts for the Irvington Parents Forum.

The Forum has also had an interesting discussion of kids learning Mandarin Chinese, including an email from a mother who is living in China so her daughter can learn the language. I'll get links posted as soon as I've read everything.

For New Yorkers and anyone else who is interested in school funding:

Per pupil spending $28,517

and

Why the tax cap passed in New York state
Pension contribution rises 37% for 2013-2014
New York State School Board Association opposes Triborough Amendment

and

English Language Arts scores 

The insanity in my state is that a school district can have nearly $30K per pupil funding and still be laying off teachers, cutting programs, laying off more teachers, threatening to cut French, Latin, and Greek, threatening to cut French, Latin, and Greek again, etc., etc., on and on.

Each and every year since the crash, we have a budget crisis: the same crisis, over and over again. It's like Groundhog Day, only not fun.

The reason we have a budget crisis each year without fail is that the budget is capped, but the contracts are not. The cap is 2%, but our contract calls for roughly 4% annual increase in compensation, and 4 is not 2. Plus pension payments will rise by 37% next year, and tax certs are through the roof (nearly $2 million this year, assuming I'm reading the Powerpoint correctly). Apparently tax certs always will be through the roof, forever. So we have a crisis.

Surreally, the solution is simple, but impossible.

All of our problems would be over if the union simply agreed to index raises to inflation. But that option is unthinkable.

The 4-is-not-2 dilemma is unthinkable even as a description of the problem. Instead of "labor costs are too high," the problem is understood to be Cost Escalation Beyond Board's Control.

Pension contributions! Health insurance! Special ed! Mandates!

True enough, all these things are expensive, but "mandates" obscures the fact that the only mandate that matters, and the source of our woe, is the Triborough Amendment. And that is here to stay.

So we are living in the land of zero-sum, where 4% raises for some mean lay-offs for others.
