Teaching is becoming a nasty job. The pay is low, and constantly under political threat. Socially teaching is looked down upon ("those who can't, teach", and "they get the summer off", "they are ruining our kids").
To some extent these concerns are founded and to some extent, of course, they are not. Teaching is looked down upon and much of that is due to teaching not being treated as much as a professional career as it should be. Another portion of why teaching is rightly looked down on is the large number of teachers that teach poorly yet are not removed as teachers due to union efforts. There are a variety of reasons why teachers don't treat their jobs more professionally. One is that the job is harder than most people think and there is nothing directly forcing teachers to treat it more professionally. There is a perverse incentive system where the teachers that work harder to teach better get paid less per hour and have less free time because the teacher that punches in the clock and goes home two second after the bell rings gets paid the same amount. Teaching certification programs and tests are far too easy, leading to teachers that do not have a broad understanding of their material. Finally, teacher development programs for active teachers are beyond terrible. They are rarely appropriately content focused or focused on the actual items that need to be addressed by each teacher to develop their teaching to be more effective. But teacher education and certification programs have a perverse incentive to turn out more graduates so they get more tuition and state money, instead of making standards and coursework more rigorous. The only solution is to make the certification tests more rigorous and test the right things, unlike the current ones. Then the teacher education programs would be forced to adapt.
But it's a vicious cycle. Because many teachers don't treat their jobs professionally, and bad teachers are difficult to weed out, parents don't have the respect for teachers. Thus the support for teachers from parents and students reduces. The answer is to change the system of incentives so that good teaching is rewarded. Better, more effective teaching can be identified, but it's not easy or cheap. Unions need to stop blocking efforts to adopt pay for performance and instead should work with schools to develop appropriate evaluations for teachers instead of rightfully pointing out that pay for performance with bad evaluation systems are not a good idea. They should also be more willing to help weed out bad teachers for the greater good of all their members.
...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.
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.
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.
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.
The original Galaxy Tab had a standard (altough not so standard because no one else use it yet) dock connector. I am sure you can get a dock->HDMI cable. Unlike the iPad, it is NOT a proprietary connector. I hope they didn't change that for the Galaxy Tab 2.
According to Wikipedia's article on PDMI:
"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.
So in other words in order to get HDMI you have to carry around a bulky dock and/or extra device. PDMI does have USB, so hopefully it allows use of both of those at the same time. 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.
Nokia better come up with some exotic hardware that no one else can produce and tie WP7 tightly to it (so it's reliance on their hardware) if they want to do this exclusive thing.
Else they are completely at the mercy of MS, where MS can dump them for another hardware manufacturer and they can't drop WP7 without losing their customer base who has invested heavy in WP7 applications.
Yeah, I think this is why Nokia's stock dropped so much. They didn't get anything out of the deal they didn't already have. They didn't get exclusivity, they didn't get control for the future, and they didn't get an operating system that is doing well already. They're really stuck with WP7 now, while they had Meego which could have given them a measure of control going forward. The costs to finish Meego and release products with it couldn't have been as bad as getting in bed with MS who have a history of trashing partners.
