A 5x3 rectangle is exactly the same as a 3x5 rectangle. It is not a bundle of bananas, silly. It's just a rectangle, regardless of orientation.
I am surprised to see exclusively negative reactions here. For one, the question wasn't marked wrong so much as partially incorrect (and partially correct). Secondly, the question is not "What is 5x3?" and the test is not about multiplication. It's explicitly about a specific process, which the teacher has presumably taught and which the student unequivocally got wrong.

If you were asked in the wood shop to make a drawer using dovetail joins and you instead make a drawer using a rabbet joins, well you shouldn't get full credit because the task wasn't about producing a drawer but about dovetail joins.

The learning objective may read "I can use control structures to solve tasks involving repetition", but if the question is "Use a for-loop to print the numbers from 1 to 10", and you used a while-loop, well again you would get partial credit but not full credit.

Many of us are computer programmers, and we know that many successful code solutions to the same problem are of equal quality. The worst code I work with is by people who never seem to care what the code looks like as long as it produced a correct result. Maybe they were only ever taught by teachers who would mark this 100% correct because they thought that answers matter and concepts don't.

I have the first version of the band, and the heart rate monitor seems to be quite accurate - I used it any my old Polar watch (where you wear a band around your chest to monitor your heart rate) and found that they typically only varied by a couple of beats per second, and the only time the band shows major fluctuations is if you don't have it snug enough so it can properly monitor the rate.

It works just fine for me both for strength training and running, and I'd certainly recommend it to others.

Most ransomware cases aren't targeted they are opportunistic, ransomware spreads like normal malware rather than some targeted "APT" operation.

And while initially ransomware operators quite "solid" and for lack of a better word "trustworthy" the popularization of it lead to everyone and their mother writing ransomware in hopes to get a quick buck.

In those cases you can't even rely on the encryption being recoverable because the malware it self is utter garbage and the criminals don't care or don't even have the technical skills to operate a full ransom cycle campaign.

It's not uncommon to see even fairly fresh ransomware examples in the wild with dead BC wallet addresses, banned paypal, skrill (and other transaction providers accounts), incorrect routing numbers etc.

This ins't 5-10 years ago where some ransomware would actually give you a voip phone-number/skype/email to call or mail and you would get to speak to some Russian or Malaysian guy give them the money and actually get a key to recover your data.

Sure some ransomware operators still operate that way, some have more sophisticated automated systems with C&C servers but most figured it out that it doesn't matter because they are in it for the quick buck and well if you are going to commit a crime then what not fraud/scam your target in the same swoop.

Ironically this reality lead to the more established organized crime organizations that employ ransomware to generate income to actively fight against the new waves of quick cash ransom scams because they need people to still have some trust in the fact that they can get their data back if they pay.

I'd be fully ok with this if the kid in question was actually learning about "Equals Versus Equivalency," but all of my school experience says that's unlikely. I hope I'm wrong.
My understanding is that Dotty is the next generation of the Scala compiler. See the Scala roadmap for the details: http://www.scala-lang.org/news/roadmap-next. Basically, it's the culmination of research showing that the language's feature set can actually be expressed in a smaller number of primitives than previously thought. A lot of features that are distinct today will become syntactic sugar for more general underlying representations. I think the expectation is that this will actually make the compiler more agile going forward,and let the maintainers cut out some of its gnarliest corners.
I agree with you. The learning objective is stated as "I can use multiplication strategies to help me multilpy", but it's important that the question asks about a specific multiplication strategy, and marks the question as partially correct because the specific multiplication strategy desired is used only partially correctly.

The reason I work for myself is that I figured out at an early age that no one cares about your job more than you do. I have been fired from plenty of jobs, so I made sure I had a nest egg as soon as possible. I also make it a point to train for my next job while I'm doing the current one. I have worked at some good jobs (Microsoft was life changing in a completely positive sense) but being so dependent on someone else seems for your livelihood never seemed like a sustainable proposition.

They do it to reduce their exposure to lawsuits from former employees. And it cheapens all their reference letters, in particular the ones given to employees that actually got along well there.
This seems like a pretty silly question, and the answers reinforce that. Getting fired by Google is like getting fired anywhere else. One of the commenters mentioned that it's harder to explain a short term at Google to prospective employers, but realistically anyone is going to understand that sometimes a particular job or team just doesn't work out regardless of the company's reputation.

So really this seems like asking what it's like to be kicked in the face by Linus Torvalds. Sure, he's famous, but it feels pretty much the same as being kicked in the face by anyone else.

Well, market fundamentalism aside, we've already made progress on the core question just by characterizing it: we need information about relative commodity scarcities and people's desires to be transmitted and collated efficiently, so that commodities can be produced to maximally meet human needs with minimum wastage.

Now we just need to find an expert in information economics and start asking them good questions!

Also, I'm not exactly a supporter of central planning, but it is worth noting, against conventional "market fundamentalism", that firms make fairly centralized and definite plans internally. So it seems that where information is scarce and radically incomplete, the stochasticity of markets helps achieve good outcomes in the same way that we might do empirical experiments in science rather than prove theorems. Likewise, where information is abundant, well-understood, and fairly complete (and where goals can be specified clearly -- extremely important!) - and where only success will be rewarded rather than failure! - the kind of planning done by firms and governments works well.
It looks like they're spaced at 30KHz, which seems to me to be a very tight grouping for any kind of transmission like that (and presumably if that band was that crowded to begin with, the author would have picked a different one).
A place like Hawaii has potential for very low energy consumption per capita: it's such an ideal environment for humans that they need little technological assistance. Little air conditioning or heating, small homes as you can spend most of the time outside, fresh food year round means little need for refrigeration etc. I think they live like that on some Greek islands and are happy and live long.
Yeah. I can certainly understand avoiding lawsuits, but they don't need to provide positive letters to do that. Just doing/saying nothing at all is sufficient.
Precisely. Is this a homework assignment? Did the teacher explicitly teach it the way it was marked? Did the teacher follow up with the student to understand why the student strayed from the path taught? Who knows, but if they did then good job. Broken foundations have huge consequences, and if being pedantic makes it easier to spot broken foundations, then it's the right approach.

>what your proposing is to isolate someone from society completely //

I think his motivation is right, to isolate inmates from the rarefied society that forms in prisons and instead to provide contact only to beneficial interactions and through useful means.

What people probably need to enable their rehabilitation is to be relatively confined but not allowed to mix with other prisoners, instead getting human interaction - if they behave well - with non-criminals who can be emotional supportive, provide aspirations, provide companionship that does not involve drug seeking or sexual power plays, etc..

The apparent motive seems worthy.

> The "5x3" problem on the test had "pure" numbers with no annotation of "objects"

It's not the "5x3" problem but the "repeated addition strategy" problem. I think that's part of the problem. Similarly, the bananas example isn't about the 5 and the 3 but about a difference between counting "x sets of y" and "y sets of x".

I don't really support the pedantry that's going on in the grading, but I'm not sure I agree with you. To the observer looking at a non-moving rectangle, "length" and "width" are not interchangable. In the same way, there are indeed a "first" and "second" by simple definition of the way English/math notation work (in other words, "left" and "right".) The student was asked to use the "repeated addition strategy" and an "array" -- if the algorithm for doing those was taught using a specific order of the operands, the student is technically wrong to swap them. Whether or not it's fair or useful to deem them wrong when they are giving an equal but non-equivalent answer, or whether or not the algorithm should care about order when the underlying mathematical operation is commutative, are other issues.
After reading this article, reading the comments here and then reading the author's follow-up to a direct message:

Comment:
This approach seems a great way to discourage smart young kids.Do we expect geometry students to grasp integrals? Want to convert kids to be math people? Laud the child for grasping the connection between multiplication and addition, use it as an opportunity to introduce the commutive property, and work on equivalence down the line….

Brett Berry's Answer:
I agree! Great opportunity for learning!!

... I would say that this author has no idea what's he talking about. Saying "I agree" to a refutation of your article is dangerously close to agreeing that your article is more rhetoric than substance. Especially when considering the self-righteous tone, this article seems little more than your garden-variety mental gymnastics: dressed up in pretty rhetoric which barely obscures the lesions of condescension, defensiveness, and disdain for others.

There's also the personal ambition of many prosecutors. See Rudy Giuliani and Chris Christie for example, and countless other US Attorneys and District Attorneys and state Attorneys General. One of the ways to enhance your reputation as a prosecutor is to have a stellar (i.e. very high) conviction rate. Plea bargains count as convictions.
>A key notion of economics is that if two people voluntarily agree to something, it must be of some benefit of them at that moment compared to alternatives else they wouldn't have agreed.

This is, of course, completely unrealistic, but in some contexts it happens to help the modeling involved in academic economics.
Only if you define morality as "allow people to interact with one another without the intrusion of force except in instances where it's used in self-defense: meaning, to rectify cases of fraud and theft." Any other moral code will recommend different government policies, particularly moral codes in which there are moral predicates other than property ownership, such as health, happiness, etc.

Wrong. "Afternoon" as commonly used is based on what hour it is, not what the sun is doing. Shift the clocks an hour, you change how much sun is in the afternoon by an hour.
I appreciate this! Sometimes articles don't convey 'this is old technology...that researchers are still refining', instead they tend to be sensational. It's nice to know that this was an older research project (2012, not 2015). I'd rather read sober reporting than to be hyped up on the 'next big thing'. Your citation does this, which is why I appreciate it.
When are practising skills in school, sometimes we practice creativity and sometimes we practice techniques. Both are useful, and it's clear which is which.

Secondly, a student that knows the difference between different techniques and can call them up at will (such as the difference between 5 sets of 3 and 3 sets of 5) is better off than a student that only knows how to produce a particular answer for a particular question.
>a difference between counting "x sets of y" and "y sets of x".

You're making the same mistake as the blog writer by overlaying a difference between "x" and "y" that was not on the test.

The child did do the repeated addition strategy. It's just that the child's "shape" of the addition didn't exactly match the teacher's. If the point of the problem was the "repeated addition" instead of the final answer "15", the child still did it correctly. He/she showed his work of repeated addition!

The actual test problem was stated as "5 times 3" and not "5subscriptX times 3subscriptY" or "5subscriptBundles times 3subscriptBananas". You're arguing about a test the child didn't actually take.

Also, I'm not exactly a supporter of central planning, but it is worth noting, against conventional "market fundamentalism", that firms make fairly centralized and definite plans internally.

And that becomes increasingly inefficient as firms get larger, which is one reason why you generally don't end up with one company running everything.

Not much. But what exactly is lost if you get 1 out of 2 instead of 2 out of 2 on a quiz in 3rd grade?

If there is a problem, it's that we can't be told that we were partially correct instead of fully correct on silly problems without it being a big deal and a failing.
Well, the official compiler is going to be replaced by Dotty eventually, so you could say that this is actually work on a far-out beta of an eventual version of the official Scala compiler.
But the question is asking the student to find a solution not something equivalent, I will agree with what this article says if the question is "Find the equivalent repeated addition form of the following multiplication problem" but it is not.
Every fact in this story is presented in a way to support the author's premise, and there are no trustworthy narrators here. If you remove the emotion, an equally plausible scenario is that he rode past a school bus that had stopped to let out students and he ignored the signals. The story only says he wasn't drunk or speeding. It doesn't say he wasn't cited for violating other traffic laws, and clearly he was cited for something because he's in jail. The article's title tells you he's innocent, and you believe it. Fine. But guilty or not, the reason I'm glad he's off the road is because he killed a pedestrian with his motorcycle.
I believe free enterprise requires that all parties to a transaction be free to participate, or decline, according to their own judgement and resources. Clearly absconding with and holding another's property for ransom is not free enterprise.

I hesitate to say something so pedantic, but with the number of people who attribute crazy properties to the concept of "free markets", etc. I think we should just be clear on this one.

Yep, the "erase your brain of that technique because we haven't gotten to that part of the book yet" reasoning was the most frustrating part of math (and science) classes in high school. It's a miracle I got through my teen years still interested in STEM. Contrast with how they treat these situations at the university level:

University: "Ahh, you seem to be pretty far ahead for MATH 140! You might as well go test out of the class and enroll in 141 instead! Save some time."

High School: "Conform to the curriculum. Repeat this technique. Obey the rules or fail."
I think the meta-lesson for the child is that there'll always be people like the teacher who marked "5+5+5" wrong and this guy who defends it with bullshit reasoning, and part of learning to deal with the world involves learning that sometimes one can be absolutely right and still be penalised/marked wrong/disagreed with, and you have to deal with that, sometimes by just answering the way they expect you to answer.

It's a pretty rough lesson to learn during a math test, though. :-\
Potentially a straw man, but:

5*(1 + 1 + 1) is equivalent. If the student had written (1 + 1 + 1) + (1 + 1 + 1) + (1 + 1 + 1) + (1 + 1 + 1) + (1 + 1 + 1), should the teacher have marked it correct? It's essentially the approach in question 2.

I'd argue that in this example, it doesn't demonstrate an understanding of "repeated addition" and at the very least should warrant follow-up by the teacher. The commutative example is more subtle and context would be nice to understand, but if this was a no consequence homework assignment that led to a quick follow-up by the teacher then it seems like a good move.
