Standardized Testing: What (Low) Scores Mean

An article on standardized testing (Revealed: The school board member who took standardized test, by Marion Brady) was published a few days ago on The Washington Post and raised my eyebrows, for it denounces a real scandal but, at the same time shows some bad reasoning that is worth analyzing here.

In short, an esteemed professional on the School Board of one of the largest school systems in the US took his state’s high-stakes standardized math and reading tests for 10th graders, and made his scores public.

How did he score?

“The math section had 60 questions. I knew the answers to none of them, but managed to guess ten out of the 60 correctly. On the reading test, I got 62% . In our system, that’s a “D”, and would get me a mandatory assignment to a double block of reading instruction.

He continued, “It seems to me something is seriously wrong. I have a bachelor of science degree, two masters degrees, and 15 credit hours toward a doctorate.

So, he got a very low score. Surprised? However, the conclusions and the logic used to get them are the real centerpiece here. Please, note that there is a logical point made here which is simply wrong: I have a science degree but failed a math test, ergo the math test must be wrong (because my science degree shows I have knowledge of math). This is a fallacy, people, one of those fallacies that math actually helps us avoid! Why? Because I may possibly not deserve my science degree!! I find disturbing that a grown-up, serious professional cannot answer any question of 10-grade math. Really disturbing. I am sure that his Korean or Finnish counterpart would very well, thanks.

But let’s go to the main points.

First, obviously both the article’s writer and the “person testing the tests” conclude that (at least those) standardized tests do not actually measure anything with accuracy.

*He said he understands why so many students who can actually read well do poorly on the FCAT.

“Many of the kids we label as poor readers are probably pretty good readers. Here’s why.

“On the FCAT, they are reading material they didn’t choose. They are given four possible answers and three out of the four are pretty good. One is the best answer but kids don’t get points for only a pretty good answer. They get zero points, the same for the absolute wrong answer. And then they are given an arbitrary time limit. Those are a number of reasons that I think the test has to be suspect.”

That’s one very good point. These tests are often too strict and offer only black-or-white kind of answer choices. They are punitive in principle: either the pupil is prepared *for the test* or she will fail. The pupil must show she is able to perform well (meaning, run during the test). I think we agree on this: these tests are bad: We should figure out a way to industrialize the testing of knowledge and skills in a more dignified way that truly assesses human potential.

The second point inferred is obviously, that these tests evaluate useless knowledge, such as -you guessed it- math.

“I have a wide circle of friends in various professions. Since taking the test, I’ve detailed its contents as best I can to many of them, particularly the math section, which does more than its share of shoving students in our system out of school and on to the street. Not a single one of them said that the math I described was necessary in their profession.

If the test-taking-and-failing person failed at math but has obtained graduate science degrees, doesn’t this all mean the math the test was trying to assess was actually useless? (This is actually a different question from the one posed at the beginning of this post).

Note that this could certainly be. My point though, is that it needs not necessarily be so. I mean, we need to undergo a full fledged math education for a number of reasons, of which usefulness is but one -and not the main. Abstracting is a cognitive skill best acquired with math, and often unconsciously. Reasoning in formal system is another. Logic, rational, rigorous thought. And then, sure, equations, percents, verbal problems, etc, up to Calculus and beyond. Thus, I consider one terrible myth the one propagated by this writer and his tester friend: First I seriously doubt the math in the test was not even remotely necessary in their profession. I am pretty sure of the exact opposite, in fact! Second, the “tester” success at his profession and graduate studies might have also been helped by his long-forgotten math: Perhaps, he may have forgotten some (surely not all!) tricky method, but likely he retained the meta-cognitive skills.

The point should be not about the usefulness of the math (or the subject area being evaluated in a test), but instead, of the tests being a bad way (when they are properly done) and a terrible way (when they are poorly prepared) of checking skills and knowledge in our students.

The test, especially in the US, is the heir of the Industrial Revolution and the idea that a huge numbers of students can be thus evaluated for alignment with one subject area or another. This is the crucial point we should try and fix.

So, instead of talking about the “need” of such subject testing (and study), which must be analyzed properly and holistically within a full curriculum, we should focus on changing the basic way we do assessment and the way it closes the doors to better educational opportunities to our students.

Programming Things to Talk

Supermechanical : Tableau physical email

Imagine Tableauone common object from your physical close world communicating with you or other objects. Not a new idea: There has been talk about the Internet of Things for some time, but this time some products are coming out and promise to bring the chance to program some particular behavior to everyday objects, like a nightstand.

Tableau acts as a bridge between users of physical and digital media, taking the best parts of both. It’s a nightstand that quietly drops photos it sees on its Twitter feed into its drawer, for the owner to discover. Images of things placed in the drawer are posted to its account as well.

I find the idea of Tableau fascinating. I have a deep respect for nightstands. I love the moment when I turn the light off, deposit the book I’m reading (or the iPhone I’m reading) on it and drink a last sip of water before sleep comes. Imagine opening up the drawer in the morning and see -not your day agenda, please- a photo being recommended to you as a gift by it -your nightstand.

The company working with Tableau and similar artifacts is about to produce a Lego-like block that can be triggered to emit Tweets when certain events happen, and which can be easily programmed. Twine is the programmable real-world block which can react to events both in the virtual and the real worlds. For instance, a Twine block can be programmed to Twit some key message when the temperature around it drops, or if its accelerometer register a sudden change. At that point, the Tweet can either trigger another block or be simply received as a final message by somebody.

At this time, Supermechanical, the genius startup behind this, is launching through Kickstarter on Jan 3rd, 2012. They initially asked for $35,000 in pledge funds, but with one month left to go, they already got over $117,000!! This means their Twine blocks will be financed and produced, and you can invest at least $35 to support them, or $99 if you want to prepurchase one block with temperature and motion sensor. As you can see from the figure, block programming occurs via a simple Web interface, so no code is needed.

Imagine I put the Twine block by the base of one of my neat green plants. When it gets dry, it Tweets my happy gardener, who can rush and water the plant accordingly.

“Copyright-infringing” downloads held legal in Switzerland: Go Swiss!

Swiss gov’t study: downloading leads to sales, so we’re keeping it legal

This nice post by Cory Doctorow in Boing Boing reports on a Swiss government study which was recently used by the Swiss to keep holding legal any “copyright-infringing” download if for personal use.

It seems to me a wonderful opportunity for other -more conservative- governments to review their own policies on downloading. The study in question shows basically that those who download “illegally”, do not end their money spending on media: on the contrary, it seems to be the exact opposite: they buy more copyrighted works, and they end up paying. But the study also shows that downloaders tend to go more frquently to concerts, thus reshuffling the obsolete equation of diminishing money because of dimishing sales. If sales (of CD’s) go down, the study shows, there are plenty of other opportunities for copyright holders to get payments for their work, if they deem so.

Last, the Swiss governmenr concluded that punitive measures, like France’s Hadopi law, may be disproportionate and should be repealed, based upon the UN’s stand that Internet access is a human right. Also, its cost, like the cost of enforcing any restrictive downloading measure may well be much higher than the economy lost to copyright-infringing downloads.

Conclusion: There is no universal legal basis to label as “illegal” any “copyright-infringing” download.

The Skin I Live In

The doctor watches the woman in a wide-screen TV, as it were a movie. The doctor has assembled and directed the woman’s life as a film director would with his actor. We have already seen this many times, also from Almodóvar himself: precisely in his great “Broken Embraces“. But here, in La piel que habito, The Sink I live In, Almodóvar breaks the limits and goes much deeper.

La piel que habitoI probably liked Embraces better, but I feel Almodóvar is going straight in a road of zen minimalism, disembracing all that is not really important to his soul searching and storytelling. His analysis of characters is compelling. All his famed humor is mostly gone; all his picaresque characters are gone (except for the Tiger, the Brazilian jolly joker whose only role is to disrupt everything and shock the viewer, and state a first brusque statement about The Mother).

The Mother archetype, before whom everyone, gay or not must come out of the closet. This is all Almodóvar shows in his movie. It’s a story of discovery and identity: Who am I; Man/Woman; where does the man begin and the woman ends? The lovemaking between the doctor and the new-skin woman is absolutely wonderful cinema: She can’t do it, because, is she a woman? He couldn’t do it before, because, was she a woman? How could he get in love with her, at the same time patient, abductee, lover? Aren’t there the same traits in all relationships? Aren’t we all, in a relationship, lovers and abductors/abductees?

Identity: The story is all a metaphor of self-discovery, of coming out of a closet, of acceptance of oneself. For this, the final scene is so powerful and clicked so much within me, so much I really felt …: the woman going to see her mother, and saying to her who she is. Or whom she has become. Or who she thinks she is. Or. Self acceptance comes after discovery (sometimes painfully, says Almodóvar), but to feel accepted we must proclaim our identity to our mother first. But who is the woman, in the end?

The doctor’s obsession is the obsession of love/relationship (and that of movie direction!), and all of the movie is about a story, a metaphor of lived relationships: manipulative, deceptive, personality-changing, person-changing. One is never the same within a relationship. One changes under the other’s power, always, sometimes subtly; more bluntly other times. This is the story, and I feel Almodóvar has matured quite a lot in the last years. He only sticks at essential, universal traits and trails and examines them under a light that is deep and natural and universal. Gone are the typical-Spaniard traits: this movie could be done in Ukraine, and nothing would be different.

A masterpiece, even if I a few minutes are really too many and would have been best cut out. Again, I felt so connected to this movie I couldn’t believe it. I was moved by it.

The Skin I live In is one, but changes: It may even grow harder. And the person beneath the skin also changes.

Like in the photo above: the doctor watches “his woman” and studies her. Beyond his irrational/rational obsession, beyond his role of captor, lover, doctor, he is trying to understand who is she, and who he wants her to be.

Thanksgiving cooking

Yes, I really had my hands dirty yesterday while dressing our little beastly turkey. The story is, this is my second turkey ever. My daughters convinced me we needed to have a nice Thanksgiving dinner, so we went out and at the last minute we bought a 14-lb bird and the other ingredients, including a nice Australian Syrah from 2006 and a wonderful sweet Marsala as both a dessert wine an to prepare the stuffing.

First we dressed the turkey with a vinaigrette made out of EV olive oil, balsamic vinegar, dried basil, parsley and thyme, salt and fresh rosemary. I mean, hand-dressed: that’s the most wonderful thing a chef must do in his kitchen!

Then, I sauteed olive oil, the bird’s liver, carrot, celery, basil, parsley and onion, together with dried cranberries, bread crumbles, minced meat, all with some generous amount of Marsala wine.

Some 15 minutes later, I added the ready stuffing to the bird’s interior, closed it up (with cotton thread!) and in the oven she went.

This is the menu we ended up with:

Stuffed turkey w/ Marsala cranberried meat, and roasted-garlic sauce

Oven-roasted sliced taro and yam

Brown mushroom risotto

The turkey was really  good in the end, so I felt doubly blessed. The girls loved every little bit of the whole enterprise.

Happy Thanksgiving!!
