    "Hmm... Over a given half-period of the sine wave, wouldn't they be the same?"

    No. The derivative of a parabola is a straight line. The derivative of a sine wave is a cosine wave.

  4. Challenge Accepted on A Mathematician's Lament — an Indictment of US Math Education · · Score: 1

    Rant time. From the original post: "I defy you to read and find a single sentence that isn't permeated, suffused, soaked, and encrusted with truth."

    Challenge accepted, for example, from the article:

    "The area of a triangle is equal to one-half its base times its height." Students are asked tomemorize this formula and then "apply" it over and over in the "exercises." Gone is the thrill, the joy, even the pain and frustration of the creative act. There is not even a problem anymore. The question has been asked and answered at the same time--there is nothing left for the student to do."

    Item (1) I have an MA in math and teach at a community college in NYC (previously Boston; algebra, trigonometry, statistics, etc.) (2) As an academic, when you start teaching, you are in for a rude shock. All throughout school, I was engaged, getting "A"'s almost all the time, and considered a "B" to be a signal of failure. The shock is to discover that the majority of people in most classes (including, unknown to you, all of your prior classmates) are unengaged, and are more-or-less comfortable with doing C/D/F work. (3) The problem discussed here (exercising area of a triangle) is, yes, trivial to someone who "gets it". However, it is very difficult to the majority of community college students that I see. For students who fundamentally can't grasp the concept of a variable, repeating algebra for years and years, and who can't "get" the idea of substitution, it's possibly overwhelmingly difficult.

    Yes, to you and me, "there is nothing left for the student to do", I agree fully. But what I've learned since starting as a teacher is that the exercises are an ongoing attempt to prove mastery of the "substitution" concept, and it's actually an enormous struggle for most people who aren't posting on Slashdot.

    I've learned that I can hand out a complete "practice test" in advance of an exam (passingly similar to this proposed exercise), and give an exact duplicate of that test in the next class, with only the numbers changed, and still have the majority of a class fail the test.

    Now, that's not all I do, but I do include examples of this just to check my own sanity all the time. What I also do now is to always include one or two "concept questions" requiring actual analysis of ideas, and the level of frustration and aggravation from the students for those is far, far more enormous. Frequently people just stop trying those by the end of a semester, leaving them blank, and are happy to walk away with a "B" or "C" from the rest of their tests.

    In summary: I now consider my #1 job in all my classes to be an effort to make students comfortable with abstraction. Give me or you a formula and then, indeed, "there is nothing left... to do". But for most students, whose brains fundamentally cannot abstract enough to grasp substitution, there is an enormous skyscraper-sized obstacle still standing in front of them. That is in fact the fundamental goal of most math classes for most students, and they certainly can't do creative exploration or problem-solving until they at least "get" that, and are able to express patterns coherently when they see them.

  17. Hidden Danger on The Case For Working With Your Hands · · Score: 1

    Two observations, having just read the article in the New York Times today:

    (1) The author's primary argument (moreso than physical work being an economic defense against the Internet) is that mechanical work gives the worker a more fulfilling life. One that is fully present, immediate, using our moral and intellectual capacities to their utmost, grounded in a community, and dealing fairly and face-to-face between owner/worker and customer.

    (2) The danger I see here is that the independently-owned mechanical work (on motorcycles from the 70's, in this example) presumes the right and capacity to actually, independently, work on these machines. Once companies put enough computer-controlled parts and DRM-equivalents into the machines, this may no longer be feasible; if so, the intellectual property regime will force even this job under its corporate knuckle.

    This actually sounds very familiar; a similar thing happened to my family when I was in high school.

    So my dad was followed kind of routinely. So was I, and so were my cousins. I got harassed one time sitting in an unmoving vehicle in my uncle's driveway -- cop pulls in behind me and and accuses me of illegal hunting, of all things. (Do I have any hunting gear whatsoever?

    I now see there's a standard protocol for company buyouts. Step #1 is where big company sends spokesperson on site to give a boilerplate spiel, "We're not changing your working practices; your culture is great, we don't want to change that; etc. etc.". All bullshit. They say that to forestall mass departures, and proceed to make whatever changes they wish, at whatever pace is desirable for them. Now I know: When your small company is bought out, leave ASAP. It's over.

    I actually do recommend that you sell and leave ASAP.

  21. Unions Want Higher Standards on Why Is It So Difficult To Fire Bad Teachers? · · Score: 1

    Here's an article on these issues from the AFT union magazine, "American Educator", last fall:

    http://www.aft.org/pubs-reports/american_educator/issues/fall2008/goldstein.pdf

    A primary problem is that principals want to fire people at-will, without evidence. The union demands legitimate documented evidence, and many principals don't have the time or interest in following that up, and therefore simply drop that responsibility.

    One thing that has been tried in places is putting teachers and the union on a renewal panel with the principal, including a regular review/evaluation process. Lesson: The union members are far more aggressive about removing bad teachers, so as to protect the quality of the profession (similar to doctor & lawyer bars). The example in the article saw an increase from 1% of teachers fired to 12% in the year that union-involved renewal boards were established. Principals are quoted as being enormously grateful for the confidence given by such oversight. (See article above, p. 10/37, item #6, "Increasing Accountability for Teaching Quality".)

    I've taught at community colleges in two states, one with a weak union and one with a strong one. I know the strong-union institution (CUNY in New York) has far more regular, and far more rigorous observation/evaluation practices, by fellow professors. At the previous job it was entirely one assistant dean's responsibility to oversee everyone, he didn't really care for it, skipped it the majority of the time (and only sat in for 5 minutes after I begged him to give me the contract-required review), couldn't understand the proceedings in the class, etc.

    Read the senate bill: http://www.ncga.state.nc.us/Sessions/2009/Bills/Senate/PDF/S1004v1.pdf [state.nc.us] I hate the telcos as much as anyone, but this bill says that when the city enters into the communications business, it should have to pay all the same taxes and fees as private business would, and be burdened with the same oversight. They also say that other fees the citizens pay (trash, water etc) cannot be used to fund the communications business. I don't see how this bill is unfair at all. The telcos are essentially saying "If we didn't have to pay any fees to the city to provide service, we could be competetive." If government wants to set up a business, they should have go compete with other businesses on a level playing field. If municipalities want to open up their own ISP, I am all for that, but then they should stop collecting fees and taxing the other ISPs they are competing with.

    Bullshit, bullshit, and more bullshit. The government is not running a business; it is providing the best service it can to the citizenry. If that prices out some private ISPs, fuck 'em. If they want to establish taxes specific to the ISPs, fuck 'em. If the people _vote to make private ISPs illegal in their community_ (perhaps because they have a history of gouging, monopoly, and privacy-breaking practices), then they can do that too!

    Municipal government should not be using taxes and fees to provide a commercial advantage for themselves. I think the "level playing field" is actually a good title for this bill, and not an unreasonable request. We're all hopped up on this because it's something that's near and dear to us, but imagine if the city set up a taxi service, but then did not have to pay gasoline tax or hackney licenses. Obviously it benefits the public who uses taxis, but is it fair to the taxi drivers and cab companies that they now have to charge more than the city taxis.

    Awesome, sign me up for that taxi service. Democracy comes first, capitalism comes second.
