  1. Re:cue exploding battery packs.... on Electric Car Nano-Batteries Aim For 500-Mile Range · · Score: 1

    I'll need maybe 20-30 days a year (only 2 or 3 days a month away), so that's 600-900. Assuming I find completely free electricity for the EV, I'll be "saving" around 600-700 in commuting fuel costs. Oops.

    There are a lot of assumptions here. One that you're going to travel more than 500 miles one way at least 20 and up to 30 times a year. Also, that gas prices will remain fairly constant. And that any incentives for buying a zero emissions vehicle for some reason don't augment the fuel cost savings. I'm ok with that, since this theoretical 500 mile per charge EV may come with a premium price tag, or maybe any incentives just offset the cost of electricity, whatever.

    Fixed (by the tax man) per-mile rate for car travel.

    In your own car. Doesn't apply to the cost of renting a vehicle for work.

    YMMV - thinking around my extended family, friends, and work colleagues I can't think of any car driver who _never_ drives 100miles away.

    On the other hand, I can think of several people who wouldn't even consider a car trip of more than say, 200-300 miles-- that's why airplanes were invented, they opine. However, I did not say people. I said cars. You may find a different result among your family and friends if you ask how often each of their vehicles make 100, 200, 500 mile trips. Lots of cars are owned by multi-car families that typically use one car (the biggest or most comfortable, whatever) on their long trips. Census data from http://factfinder.census.gov/ show that about 55% of households have 2 or more vehicles. So again, while it may not quite work for you, there are lots of people for whom an EV -- even with perhaps as little as 100 or 200 mile range -- would work just fine.

    Our federal government mandated testing is done on one day, for one single class. It is never repeated. There is no "November vs March" comparison. The students are tested once, and are never tested again.

    Good to know, but not related to my point. My point was along the lines of short term vs. long term memory, i.e. if you only can recall a set of facts or concepts long enough to pass the test (in class test, not the standardized test) at the end of the week they're covered in class, you haven't really learned it.

    We take one single test in November, and compare the raw average, ignoring any variance or standard deviation, to the raw average of the students who took it last year. (Yes, a completely different population of students!) It is truly a single data point.

    By that logic, any study/survey/data collection only done once contains only a single data point regardless of how many questions/assays and/or respondents/subjects there are.

    One year on one test, my school pulled something like 1107, when the state cutoff was 1110. Due to this, we were placed in the "below average" category. Never mind that the test error bars are like 30-50 pts.

    Your assumption seems to be that the error bars are not considered when setting the cutoff. I don't know that that assumption is any more valid than the assumption that they are.

    My Master's thesis looked at the fact that 3 zeros could push us from passing to failing. Three kids could blow off the govt mandated test which didn't affect them, and because we only report a raw average with no error, they could cause us to fail.

    If that's true, then the way scores are aggregated and used is bad. No-shows for the test should be counted as NULLs, not zeros since those scores are unknown. I can see having some penalty (administratively to the school, not against the actual test scores) if some percentage of students don't take the test, but mixing non-scores with actual test scores doesn't make sense.

    To be fair, it seems like we may be arguing somewhat different points. My point is that there is utility in standardized testing-- it allows you to control for subjective factors, etc.... The more I read you, the more I see that you're arguing against the way scores are used rather than against standardized testing itself. With that in mind, I don't think we really disagree that much.

  3. Re:cue exploding battery packs.... on Electric Car Nano-Batteries Aim For 500-Mile Range · · Score: 1

    At first glance, the commute would be ideal for EV, but if I still need the other car to cover the long trips it just doesn't add up. The fixed costs on the car (tax, insurance, servicing & repairs) are actually _more_ than the fuel costs of my commute over a year

    Except that you don't have to buy the second car. Rental rates are not that steep. Or as Rei suggested, just rent a towable generator for your EV. If the trip is for work, expense it.

    For me, a viable EV needs to do practically everything a current ICE car can do so it can replace it.

    Fixed that for you. But seriously, to replace a particular ICE car with an EV, the EV only has to do what the ICE car does, not what it can do. Contrary to your opinion, I suspect most cars never travel more than 100 miles from home, nevermind 500 miles in a day. And unless you're single, being a 1 car family would be the exception rather than the rule.

    You make some good points, but I'd like to nit pick a few things.
    1) Mostly agree. School boards, though, are local. Some are going to do well, others poorly. And their power varies too.
    2) Agree, but I don't think multiplication is a good example.
    3) Yeah, testing is hard. But unless the tests are one question now, it is not one data point. And while it is one day a year, it is designed to test what you've learned. If you "knew" some set of facts in November when they were being covered, but you don't know them for the test in March, did you really learn them? Standardized tests are for measuring what students know on an even playing field. They're not perfect, but standardized tests do control for weak curricula, teachers who grade easy (or hard), and similar factors.
    4) Mostly disagree here. Hundreds of years ago, your career was mostly determined by what your father did, but we don't really do things that way anymore. I'm a fan of giving kids a well rounded education (trying, anyway). Maybe senior year you specialize if you know you want to go a particular way. Lots of schools have vo-tech programs that address this.
    5) If you're talking about better ways of teaching math, I'm in favor. Most high schoolers seem to have fairly limited grasp of solidly useful, basic math concepts like area and volume, angles, the Pythagorean theorem, etc... so we certainly don't need less math. But I'm intrigued by the idea of integrating it into other subjects.

You should qualify for all kinds of public assistance like welfare, food stamps, AFDC, Medicaid... oh, there we go. Problem solved.

  14. Re:The Silent Side of the Coin on Student Arrested For Classroom Texting · · Score: 1

    There are other unsaid/unseen aspects here too. I have a good friend who is a teacher. He's smart and likes helping the kids, but he's always talking about quitting for basically the opposite of what we see in this article. He will have someone disrupt his class and have little to no authority to remove or punish the student. If he sends the kid to the office, the kid comes right back and the teacher later gets told by the administration to "deal with it" even though all he really has the authority to do is send a kid to the principal's office. Once the kids figure out that there are no consequences, the teacher is pretty much SOL.

    In the case in the article, the administration is at least supporting the teacher's authority. It sounds like the officer is permanently assigned to the school, and therefore effectively part of the staff normally involved in keeping the school secure and dealing with unruly or disruptive students. Now, whether the student should have been cited (not arrested as the article falsely claimed) for disorderly conduct is debatable. Was she disrupting the class by trying to covertly text? It was obviously a distraction to the teacher. Could be that the district's policy calls for that level of consequence before a student can be searched.... just speculation though. Could also be that this was a second, third, fifth, nth offense and the school/officer are just continuing to escalate the consequences. The police report is public, but the students school disciplinary record is not, so we can't tell if this is just the next step in a progression of attempts to deal with the student.
