    ...and my job is NOT funded by tax payer dollars, nor is it nearly as important as educating children.

    Which makes it all the more important that the metric used for the evaluations is a good one. If the metric used for your evaluations at a private company are a bad one, pretty much only the owners of the company and employees suffer. If the metric used for evaluations at a public school are bad, it can have a heavy cost to a generation of kids. In this case, the union isn't just whining that we don't want to be evaluated and don't want them to be public (though they seem to do that too whih hurts their credibility), but they are correctly calling the evaluation method into question. The evaluations in this case are based on regression of multiple choice results of students, and have a huge error rate. There are ways to evaluate teaching performance that are effective, but this isn't it. The good ways are more expensive, and aren't as easy to check a box to say they're done. Tough luck. Doing a job right doesn't have to be easy, but as you say, it's important, so it is worth doing right.

  2. Re:So, the teacher wants to hide the report card? on NYC To Release Teacher Evaluation Data Over Union Protests · · Score: 2

    As a teacher, I know that evaluations of my technique can help me hone my skills and become more effective. The public teachers in NYC should take the critique and act upon it to make them better at their jobs.

    Yes, good evaluations can do that, but these aren't it. In this case the Union is right. These "evaluations" aren't evaluations, they are results of multiple choice tests run through a regression. Anyone with two bits of understanding of statistics knows to take a regression result with a block of salt, and when you start with bad data that compounds the problem. It is widely considered among education researchers that multiple choice tests do not measure well what a student knows.

    If the NYC school system is using bad data and bad statistics like this to make decisions, then they are going to get the obvious result. Teachers will (even more so) teach to the multiple choice test instead of teaching for understanding, and good teachers will be fired or mentored away from being good teachers because of the high error rates in the method. Now of course, the NYC teachers union is also well known for being a significant hindrance to quality education. Their interests just happen to line up with what is right in this particular case. In general they don't want any of their members fired for any reason and will oppose any method of finding out which teachers are poor teachers and weeding them out.

  3. Re:People don't realize doctors can be sued for . on Doctors "Fire" Vaccine Refusers · · Score: 1

    Amazingly, it even gets worse than that. I know a Dr. that often does work as a medical expert in court cases. In one case a family refused vaccination, were educated about the risks, and signed a very strongly worded consent form including being aware that their child may face death or serious illness as a result of not being vaccinated. One of the children went on to contract a disease that the vaccines were designed to prevent and sued. Who do you think won? The family did of course, because the Dr. didn't try hard enough to educate the family about the risks. What exactly should they do, spend their entire day trying to convince people that won't listen anyway?

    Whoever came to that asinine decision should be sentenced to spend even just a single week trying to education nutter non vaxxer moron parents about why they should get their children vaccinated. In ten minutes they'd cry uncle at the unending stupidity of the non vaxxers and how unwilling they are to listen to any reason. Somehow they are all convinced by completely unscientific arguments that they all bandy about amongst themselves and will listen to nothing else.

    So the result is non vaxxers will increasingly get fired by mainstream primary care physicians and there will certainly be plenty of quacks willing to tell them what they want to hear and take their money. The problem is it's the children that suffer not the parents. The children will get lower quality care. I think it will take nothing less than a widespread pandemic to change the situation and that may not be enough to change the minds of non vaxxers. It will probably take defining vaccine refusal as child neglect to actually fix the problem.

  4. Re:His brain is better than mine on UCLA Professor Says Conventional Wisdom on Study Habits Is All Washed Up · · Score: 1

    When I hear educational theorists pronouncing with dogmatic certainty that lectures are an ineffective method of instruction I think back to that course, and find that I am skeptical of their dogma. Lectures are no doubt ineffective in many cases, but I think that such masterful lecturers are the exceptions that disprove their axiomatic claims.

    A counterexample in special circumstances doesn't necessarily mean the general case isn't true in most cases. You would be hard pressed to find educational theorists that make absolute pronouncements that lectures don't work. What they will usually say is that they don't work as well in many or most cases as they should and that the evidence is building that there are better ways.

    What you have in your case is either anecdote, it worked for you, or possibly a set of students that were all of similar preparation and ability and it worked for them. This is likely because you refer to a high level class with a lot of prerequisites and only the most dedicated students tend to take it. Of course, this is after selecting out students that didn't make it into your university or program. As the background knowledge and abilities of the class vary more, however, lecture tends to fail for more and more students. Any instructor intending to lecture has to essentially pick a target group to lecture towards. Those with better background knowledge and abilities than the target will be bored stiff, those with less will be lost. There is very little range in the lecture format to accommodate a wider range of abilities and successfully transmit a large amount of information and understanding to all of them. There is the additional factor of instructor skill. Very few instructors are skilled enough lecturers to do it well. That a few are does not automatically mean that lecture is the best or even a good overall teaching format for most students given that most instructors are poor lecturers. But don't take it from me even though I am an educator and have studied this stuff. If you want to know what you're talking about, take a look at success rates in lecture driven classes in a variety of circumstances and the literature on different teaching methods.

  5. DIY vs Purpose built on Ask Slashdot: Building an Assistive Reading Device? · · Score: 1

    Indeed you can set one up to an extent. The products you are referring to are known in general as CCTV's in the assistive technology/low vision community even though they don't necessarily involve a television anymore. The one thing to keep in mind is that the purpose built and sold products such as the ones you linked to are built with specific features such as contrast enhancement, color adjustment, (and more I'm sure I don't know of), that are effective in helping people with various types of visual difficulties. For example, they can switch a book placed in front of their camera from black on white to display on a screen as white on black, or change it to red on black, etc. Perhaps your girlfriend's grandfather's doctors or specialists could say whether those types of things or other features that these types of purpose built devices have would help or would be able to extend his ability to read printed text. Many also come with a table that slides in the x and y directions to make it easy to move a book around. A large smooth table can work similarly, but it's not as convenient. The other thing to realize is that the reason those devices are so expensive in many cases is that they are built for one purpose and thus are able to qualify for health insurance coverage. That's an unfortunate feature of most health insurance, but they don't want to pay for general purpose devices like a computer, even if it could be used with built in screen reader software like on a Mac (VoiceOver), because that computer could also be used for general purposes. So the result is much more expensive single purpose devices. Go figure. But as explained above, in some cases, they come with features that would either be difficult to duplicate in a DIY solution, or would take quite a bit of research to find out what features are best for a given condition. Maybe your girlfriend's grandfather would qualify for insurance coverage anyway. In this case, given that his condition is degenerative, perhaps, a DIY solution is better if it can work, if it would be cheaper.

    Another option is to consider screen reader software such as VoiceOver that comes with Macs or JAWS or WindowEyes that can be purchased for windows. JAWS and WindowEyes are more serious, full screen reader solutions. A screen reader is certainly not an easy learning curve. They replace the standard computer navigation with an entirely new keyboard (and mouse work arounds) and audio based one.

    Another option is custom Audio book creation. You can build a DIY book scanner diybookscanner.org/ and ocr any book or page, then use text to speech software to create an audio book. With custom voices they can sound pretty good, though it takes a lot of work to clean up the text input to get nice clean output.

    People have already linked the KNFB reader software, which is worth looking into. It's pretty slick, I've seen it in action. It's pretty well optimized and runs on a Nokia cell phone.

  7. Re:It's like a religion on Measles Resurgent Due To Fear of Vaccination · · Score: 1

    Ironically, having rejected comparatively perfectly safe vaccination options, parents seem to have no issues with then putting all the interventionist methods to use to save their children if they do fall sick. I.e. take them to the hospital, operate, perform lots of heroic work to save the child... all of which would not have been necessary if they hadn't blindly followed quacks advice re: vaccinations.

    Actually it's even far worse than that, sadly. People who refuse vaccinations and sign harshly worded consent forms designed to get them to think twice about their stupidity (including "your child may die or be seriously ill as a result of not getting this vaccine") will turn around and sue the very same medical practitioners that tried to get them to take the vaccines when they end up getting the disease the vaccine was designed to prevent. Somehow they can even win cases like this on the twisted reasoning that the doctor should have tried harder to convince them to get the vaccine. Anyone that thinks that way has never tried talking for two seconds to one of these non vaccinator morons and how unwilling to think they are. So the only option the practitioner has is to terminate the patient from their practice which may leave the child with no mainstream primary care physician and much worse medical care.

    The other thing that really burns me up about non vaccinators is they lie and use a so called religious excuse to get their kids into school and place all other kids at risk. So the only option I have to keep from exposing my kids to the risk that non vaccinators have created would be to socially isolate them. I think schools should push for much stronger evidence of religious beliefs and get the religious leader to sign a very specific statement to justify why the family is placing other children at risk. I'm pretty sure there aren't any mainstream religions that have a prohibition against vaccinations so its a big lie anyway.

    "DisplayPort signal can be converted to HDMI format using active converter circuitry in the dock or external signal conversion adapter powered by 3.3 V DisplayPort power.

Either way, it's much more clunky than having them built in. Being able to hook the tablet up to a monitor and keyboard and external storage would make it much more useful. In that case it wouldn't matter that those things are large and unportable, the use case would be having a monitor and keyboard at the office and at home or the ease of hooking into a projector. I suppose it's not the end of the world to carry a VGA adapter and a dock connector, but it defeats part of the purpose of the small tablet.
