Head Start has new director - NewsRegister.com - News and ...
Marcus Larson / News-Register
Suey Linzmeier has replaced Michael Eichman as Head Start director.
Sep 29, 2012
By Starla Pointer
Of the News-Register
Suey Linzmeier has been named executive director of Head Start of Yamhill County. She replaces Michael Eichman, who is retiring after 17 years in the post.
Linzmeier previously served as assistant director and coordinator of the Early Head Start program with the nonprofit, which operates centers in McMinnville, Dayton, Sheridan and Newberg. Before that, she served as a family educator and teacher at the Sheridan center.
Head Start is a federal- and state-funded program that promotes school readiness for children from low-income families. It is currently serving 415 children, pre-natal through age 4, in Yamhill County.
Its programs aim to enhance children?s social, cognitive and emotional development through services involving their health, nutrition, socialization and education. Staff members work closely with families as well as youngsters, focusing on parents as children?s first and most important teachers.
Linzmeier said the best part about Head Start is that it?s not a program just for children. It serves entire families.
?It?s a human development organization,? she said.
She said Head Start staff members work with parents to teach them the skills they need to improve themselves, as well as to become better parents.
Every family has to set goals. As a result, she said, last year 22 Head Start parents earned their GEDs, while others regained custody of children, made down payments on homes or started college.
?We?re the ones who believe in them,? she said. ?A lot of our families didn?t have good situations when they were growing up, and they need to learn how to be really strong parents. We help to teach them.?
Many Head Start parents go on to get good jobs, she said, and some find jobs with Head Start itself. In fact, she said, 30 percent of the local staff members started as parents in the program.
Linzmeier moved to Yamhill County in 2007 from Juneau, Alaska. She had worked in early childhood education during her 25 years there, serving as program manager for the Association for the Education of Young Children Southeast?s child care food program, adjunct professor at the University of Fairbanks and chapter founder of the Alaska Child Care Food Program Sponsor Network and Alaska Family Child Care Association Southeast.
She holds a degree in child development and family studies from the University of Alaska-Fairbanks and a graduate certificate in infant toddler mental health from Portland State University.
As part of her work with Head Start of Yamhill County, Linzmeier has served as liaison to the Yamhill County Commission on Children and Family?s Early Childhood Coordinating Council. The council, a collaborative effort of several agencies, aims to ensure that all young children and their families have access to quality resources that support growth and development.
She also has helped Head Start win a federal grant to expand its services to 48 expectant families, as well as infants and toddlers.
Eichman, the former director, is still involved with Head Start on a contractual basis, as the agency considers development of additional facilities.
He said he is pleased with the choice of Linzmeier as his successor.
?She has been with the program long enough to have achieved measurable success with both Early Head Start and our Head Start program,? he said. ?Her leadership skills are impressive. She is clearly the right person at the right time in the right place.?
For more information, call the office at 472-2000 or visit www.yamhillheadstart.org.

Top 10 ways to Ditch Your Clutter and Digitally Organize Your Life [Video]
We've all got a few cabinets, drawers, and shelves filled with clutter that seems outdated: CDs, paper, photo albums, DVDs, and books take up a lot of space. Here are 10 ways you can take the plunge into a digital, clutter-free life.
10. CDs, Records, and Other Music
If you were alive before the age of iTunes, you probably have countless CDs, cassette tapes, and records lying around taking up space in your house. Maybe you have some of them in your digital music library, others you don't. Well, now's a good time to digitize everything and get rid of some of that clutter (well, the clutter you're less emotionally attached to, at least). Ripping CDs is easy, but if you want to rip those old records, you'll have to do a bit more work. While you're at it, make sure you're ripping everything in high quality?after all, you might just become an audiophile in the process.
9. Photos and Slides
Your digital camera makes digitizing photos easy?all you do is transfer them to your PC?but if you have a lot of old photo albums, it might be a good idea to scan those into your digital library to keep everything together. Scanning regular photos is easy, and you can easily touch them up with software to make them look crystal clear. Then, just organize them using a library like Picasa or Lyn, and sync them all up to the cloud so you always have access. If you have some old negatives lying around, you can easily scan those in too.
8. Post-Its, To-Dos, and Other Notes
Pen and paper is still one of our favorite to-do list managers, but if you find that you get buried under disorganized scribbles and Post-Its, it's time to take it all digital. Use a to-do manager like Astrid or Wunderlist to keep track of your tasks, and a program like Simplenote to capture, organize, and sync all your simple text notes. If you really want to go all-out, you can use something like Evernote, which lets you capture nearly anything into a searchable, syncable database, so you always have those little notes on hand.
7. Business Cards and Contact Info
Despite what many people say, business cards are not irrelevant quite yet. But, they can get lost easily, and clutter up your wallet, car, desk, or whatever other place you choose to stash them. Instead of hoarding tiny pieces of paper, scan them into your phone as contacts using something like Google Goggles. You can stick them all in their own contact group, so they don't clutter up your personal contacts, and you'll always have that info on hand when you need it. Plus, when you want to send that info over to someone else, you don't need to fumble for a business card?just send them the digital contact via SMS, email, or Bump.
6. Books, Magazines, and Newspapers
Some bookworms may shudder at the thought of giving up their physical books, but it can help you reclaim a lot of space. Ebook readers are cheap, and you can load them up with ebooks without spending a dime. If you get a Nook Simple Touch, you can even root it and turn it into the ultimate reading machine with some bookmark-and-read-later apps, some news aggregators, or whatever else you want. iPads and Android tablets have a lot of digital newspapers and magazines available in their respective app stores, and they work quite nicely?not to mention you can visit nearly any publication's web site for the latest news on any given subject.
5. Recipes and Other Kitchen Tools
If cooking your daily meals and tracking what you eat has gotten too complicated, a switch to digital might be just what you need. Ditch that old recipe box for a recipe library on your computer, or even better yet, get a meal planning app and plan your weekly meals stress free. Not only can you store recipes, but you can create grocery lists based on what you're going to make during the week, saving you the headache of sifting through recipe cards, and tiny grocery lists. While you're at it, grab a couple of these apps so you can better track what you're eating and stay healthy.
4. Movies, TV, and Other Video
If there's one thing that took up more space than anything else for me, it was the giant shelf of DVDs, Blu-Rays, and other video media. There's no need to have all of those around, though. Build yourself a media center or buy a cheap-but-awesome set top box for all your digital video needs. You can stream movies and TV through services like Netflix, Hulu, and Amazon, or you can rip all those DVDs and Blu-Ray discs right to your hard drive for playback on your TV, and download anything of the holes in your collection. Not only will you get rid of all those discs, but you might even get rid of a box or two from your media cabinet.
3. Gift Cards, Loyalty Cards, and Event Tickets
Raise your hand if you've ever forgotten to bring your concert ticket to the concert. Ever forget to put the right loyalty card in your pocket, or even forget that you have a gift card for the store you just shopped at? Moving these things to your phone can not only save you some space in your wallet, but it can help you keep all that stuff organized. iOS 6 just introduced Passbook, a great way to manage your gift cards, coupons, loyalty cards, and event tickets right from your phone. You can also get Passbook on Android with Passwallet. Alternatively, use a program like Key Ring to scan in all your loyalty cards so you have each of them on hand at all times, and use a program like TripIt to get digital information about your flights when you travel. The more you can put on your phone, the easier it'll all be to access.
2. Money
Okay, so paper money and physical credit cards aren't so easy to get rid of, but you can do a lot with your phone. Not only can you manage your money and budgets with something like Mint, but you can actually pay back your friends with services like Square or Dwolla (or, if you must, PayPal). Some banks even have an easy way to make digital payments between friends. If nothing else, it'll make it easier for you to stop carrying around that checkbook, or stop worrying about how much cash you have on hand all the time.
1. Paper Documents, Manuals, and Everything Else That Comes From Trees
Okay, so you're really committed to this digital thing, which means it's time to round up all the paper in your life and convert it to a digital format: bank statements, insurance statements, bills, and even the manuals that come with all your gadgets. Okay, that last one is pretty easy to do?just search for the manuals on Google and toss out the paper?but everything else is a bit more complicated. Check out our complete guide to going paperless and how to make the transition from paper for information on how to digitize, how to store it all, and what things you should still keep around in paper form.

Why the next civilization is NOT Rome

Why the next civilization is NOT Rome
First and foremost I wanted to say that some people have "leaked" information, trying to proof that Rome is the next civ. However, there's no point in those "leaks":
1.) The information could simply be fake.
2.) Posting those leaks gets you banned for you trying to proof old news:
3.) There have been signs that GPG is working on a Roman civ since january and proofs could be found in their official videos.
So, we know without any leaks that Romans are being worked on.
But why aren't they the next civilization? I'm going to use official information only to proof this:
1.) They're working on a overhaul for the quest campaigns:
We also intend a major re-thinking of the structure for the existing and future campaigns to improve the "build an empire" feel of Age of Empires. Work has started on these changes?but we aren't quite ready to divulge the details. Yet.
If they're already working on it might be wise to just create the Roman campaing with that new structure in mind and just wait with their release until that structure is implemented for other civs also.
2.) They have been working on the Romans since January (see above). Developing a Pro civilization is a lot faster than developing a Premium civilization, because Premium civs usually come with new gear types and more advanced features than Pro civilizations as well as a dozens of quests. GPG worked on the Celts for nearly a year, this might also be true for the Romans. Between the release of Premium civs GPG always squeezed in a Pro civ.
3.) In the video I linked above the Roman art was already finished while they still had modelers, texturers and concept artists working on Babylonian art (you can see their Fishing Boat and Treasury being worked on amongst other things). As it totally doesn't make sense to finish one Pro civ and create another Pro civ before releasing the first, Romans must be a Premium civ.
4. In another video, they showed Rome points.? Rome is not under "shared currencies", that means it's not a shared region and definitely not a booster pack (as that'd be shared as well). It's under "region" currencies. Ever Premium civ has exactly one unique region currency. Currently there are Mycenae (Greek), Nubia (Egypt) and Massalia (Celts). The only civ that would make sense to have Rome as some sort of quest city would be the Romans themselves
5.) As Rome is a Premium civ, it cannot be the next one.

Re: Why the next civilization is NOT Rome
Thank you!
>I know the next civilization that will be released this fall. -
Re: Why the next civilization is NOT Rome
oh my mind, idk I really don't care anymore on what the new civ is.............
but you have to keep in mind the one year delay on celts was probably the tech tree overhual and the huge chunk of changes from summer patch
still we may never know till time or the devs do its part
edit:not one year more about 3 months or so
Hooray celebrate with me!! I just earned the title of biggest noob and idiot of the year awards -
Re: Why the next civilization is NOT Rome
First and foremost I wanted to say that some people have "leaked" information, trying to proof that Rome is the next civ. However, there's no point in those "leaks":
If theres no point why does it matter if we talk about it.
?
1.) The information could simply be fake.
Well if its fake then GPG can chuckle?evilly and laugh at us since they trolled us hard. Because they are the ones who ~leaked~ all of this information. The majority of the information about Rome and Babs (when it?happened) came to light when people read an XML file that came with the game. It wasn't packed in a bar file, nor was it scrambled in anyway. However discussing the contents of that file is a bannable offense.?How is it leaking when we already have the content on our machines, and can easily access it.?Worst case? Its fake, and GPG trolled us. Or the units were changed like every other game during development.
Look at Mass Effect 3 and how chunks of the story text were in the demo's data files. Did Bioware turn around and start banning everyone, from talking about it on their forums? No. Or how Deus Ex Human Revolution E3 Demo was leaked, did Eidos make talking about it a bannable offense, even though technically it was stolen? Nope, they even went so far as to encourage discussion about their game, leading to more hype.
However hypthothesising ?about the uses of the new potential units, is a bannable offense. So instead general gets filled with people crying about wanting to know who the next premium civ is, or the 50 threads?consisting?of everyone arguing and guessing over the next civilization.?Honestly what difference does it make? Would you rather people be brainstorming what is coming, or the General discussion forum to be filled with topics where everyone is arguing over who should it be.?
Now i understand that you have some exclusive agreements for people to break the news (yeah Eurogamer breaking the news about Babylon was off their front page in almost an hour). However how are you even violating any rules when you are not breaking this information early. For all we know the developers just planted that stuff there to troll us.?
Yeah we already know Rome is coming, nobody is arguing they aren't. Furthermore people aren't trying to ~prove old news~ people are trying to figure out what units/special tech is coming for Rome. However discussing any information beyond "Hurf derf rome is coming", pretty much borders on bannable.?
?

Maybe they had problems turning Rome into a premium civilization. So they decided to make it a procivilization. Who knows? Saying otherwise is speculation. Also considering GPG has pointed out in the past they love leaving us red herrings, maybe making all that information about rome was a red herring. Who knows. Will it really?thwart?GPGs plans that people already know some of the units that Rome may possibly have?
TLDR; Butthurt.?

Re: Why the next civilization is NOT Rome
I remembered another clue that a) Rome is in the works and b) that they're a Premium civ:
4. In another video, they showed Rome points.? Rome is not under "shared currencies", that means it's not a shared region and definitely not a booster pack (as that'd be shared as well).

The difference is that Rome is not coming very soon. There's no use hyping something that might not come out in the next three months or more. And there's no use discussing units that might very well undergo a change. Woad raiders weren't the Woad raiders we know when GPG first implemented it, Rams were an advisor units and Call to Arms worked like the one in WC3 and it wasn't a tech. Oh and GPG implemented Stone Throwers relatively late.
Maybe they had problems turning Rome into a premium civilization. So they decided to make it a procivilization. Who knows? Saying otherwise is speculation.

Why would they? Removing content is a waste of money. There are two definite clues that Rome is a Premium civilization, and a reasonable theory on top of that. You have nothing to proof that they turned Romans into a Pro civilization.
There's not a single red herring that is in form of a screenshot or video. The only red herrings are jokes from AOEO Trajan. And most of his hints actually hinted towards the correct civ last time, not to a false one.

I never said every info is fake, and nobody ever said the developers put fake info in their files. However everyone who "leaks" something can fake it and claim it as a leak.
Assuming they fake a leak of lets say unit information, it would take 30 seconds for someone to check the files to prove them wrong. Anyone can extract the data files (There is even a full blown tutorial on the age of empires online wiki). I could go and say i am leaking that the next civilization is X, maybe one or two people might believe me, i would get to troll some people, and then someone would point out i am lying, or they would realize it when i have 0 proof (what good is creating fake files, when someone can verify it in 30 seconds).?
?
The difference is that Rome is not coming very soon. There's no use hyping something that might not come out in the next three months or more. And there's no use discussing units that might very well undergo a change. Woad raiders weren't the Woad raiders we know when GPG first implemented it, Rams were an advisor units and Call to Arms worked like the one in WC3 and it wasn't a tech. Oh and GPG implemented Stone Throwers relatively late.
Starcraft 2 took 3.5 years from when the game was announced, to when the game was released, the game changed an insane amount units were dropped, techs were dropped, new units were added, etc. People still talked about them because you know what? Its something to talk about. Since forums are supposed to be a community for a game.?
GPG gave us all this cool information, but we aren't allowed to talk about it even though its basically sitting there asking for us to open it. That would give people something to get hyped about, who cares if the units don't make the cut, or change completely (Starcraft 2 had a ton of units cut between annoucement and release). Tons of people are waiting for Rome, to come back to play the game.?
Why would they? Removing content is a waste of money. There are two definite clues that Rome is a Premium civilization, and a reasonable theory on top of that. You have nothing to proof that they turned Romans into a Pro civilization.
There's not a single red herring that is in form of a screenshot or video. The only red herrings are jokes from AOEO Trajan. And most of his hints actually hinted towards the correct civ last time, not to a false one.
Removing content isn't a waste of money when the revenue generated from finishing it and selling it, results in a net loss.?I misspoke, i was simply implying that anything is possible, we have not heard anything about Rome in ages. Furthermore there is no mention of another premium civilization coming after this next prociv.?
The whole point i am trying to make, is this isn't a leak, merely discussing what GPG already gave us. If they didn't want to us to know about this information, then they wouldn't have:
- Left a ton of Art for Rome in the data files?
- Left Misc data files for Rome
- Put the entire roman tech tree at the time in an XML File.?Separate?from the binary files.?
You still haven't explained why letting people talk about this?publicly?available knowledge is a bad thing. I also fail to see how that is a 'bannable' offense since it hurts no one.?
-
Re: Why the next civilization is NOT Rome
For the developers it's important information is not leaked before any announcement to get proper media coverage and attention exactly when it is needed. And I doubt anyone will ban anyone for telling a couple of unit infos when the respective civilization is officially announced.
"They gave us to look at" and "they have better things to do, namely adding a whole lot of features, civs and content instead of hiding old data from us" is a whole lot of a difference:?
I think it might be even beneficial for you as a player not to leak any content as the developers will have to take bigger efforts to hide content, ultimately slowing down content production. And websites like the AoEO Wiki, the AoEO Database or the new AoEO Market won't be able work anymore.
And let's get back to topic please. If you have any questions about moderation decisions, feel free to PM me or any other moderators.

after reading this, i feel very happy (my guess for the civ is Phoenicia, they are a rival of Rome)?

Stanford Law Exceeds Financial Aid Budget
Hard to believe, but apparently Stanford Law School has run out of financial aid money and has to dip into its unrestricted funds to meet its needs.? Blame the economy on two fronts.? One is that the return on investments is lower due to the economic climate.? The other is that more students qualify for financial aid for the same reason.? The Stanford Daily has the story, noting that the average award for aid is $25,000, leaving students with an average debt of $109,000 at graduation.? I wonder how other schools are coping if this kind of thing is happening at Stanford.? I give Stanford credit for continuing financial aid under these circumstances.? [MG]

Samsung Array (Sprint)
It's getting harder and harder to find a good phone?these days that isn't a smartphone?and that goes double if you're looking for something with a keyboard. The $19.99 Samsung Array doesn't do much to remedy the situation, but at this point, any option is a welcome one. To that end, the Array is a simple feature phone with a decent slide-out QWERTY keyboard. It doesn't have 3G, and its feature set is rather limited. But if all you want is to talk and text, it should suffice.
Sprint's Version and Conclusions
This is the same phone as the Samsung Array?we reviewed over on Boost Mobile.?For a closer look at the phone, read our review and check out the slideshow below. It's the same device, and since Boost runs on Sprint's network, we expect it to perform similarly.
There are so few keyboarded feature phones available that I don't want to ding the Samsung Array too much. If you need to talk and text and not much else it should do the trick. The LG Rumor Reflex??is another decent option. It has an eco-friendly design with a larger display and a nicer keyboard, though it isn't as simple to use as the Array. The Kyocera Brio??has a BlackBerry-style slab keyboard and better call quality, but next to nothing in the way of features. The Kyocera Milano, meanwhile, features a whimsical design and decent call quality, but also comes up short for media.?

Nickelblock: An element's love-hate relationship with battery electrodes
ScienceDaily (Sep. 27, 2012) ? Anyone who owns an electronic device knows that lithium ion batteries could work better and last longer. Now, scientists examining battery materials on the nano-scale reveal how nickel forms a physical barrier that impedes the shuttling of lithium ions in the electrode, reducing how fast the materials charge and discharge. Published last week in Nano Letters, the research also suggests a way to improve the materials.
The researchers, led by the Department of Energy's Pacific Northwest National Laboratory's Chongmin Wang, created high-resolution 3D images of electrode materials made from lithium-nickel-manganese oxide layered nanoparticles, mapping the individual elements. These maps showed that nickel formed clumps at certain spots in the nanoparticles. A higher magnification view showed the nickel blocking the channels through which lithium ions normally travel when batteries are charged and discharged.
"We were surprised to see the nickel selectively segregate like it did. When the moving lithium ions hit the segregated nickel rich layer, they essentially encounter a barrier that appears to slow them down," said Wang, a materials scientist based at EMSL, the Environmental Molecular Sciences Laboratory, a DOE user facility on PNNL's campus. "The block forms in the manufacturing process, and we'd like to find a way to prevent it."
Lithium ions are positively charged atoms that move between negative and positive electrodes when a battery is being charged or is in use. They essentially catch or release the negatively charged electrons, whose movement through a device such as a laptop forms the electric current.
In lithium-manganese oxide electrodes, the manganese and oxygen atoms form rows like a field of cornstalks. In the channels between the stalks, lithium ions zip towards the electrodes on either end, the direction depending on whether the battery is being used or being charged.
Researchers have known for a long time that adding nickel improves how much energy the electrode can hold, battery qualities known as capacity and voltage. But scientists haven't understood why the capacity falls after repeated usage -- a situation consumers experience when a dying battery holds its charge for less and less time.
To find out, Wang, materials scientist Meng Gu and their collaborators used electron microscopy at EMSL and the National Center for Electron Microscopy at Lawrence Berkeley National Laboratory to view how the different atoms are arranged in the electrode materials produced by Argonne National Laboratory researchers. The electrodes were based on nanoparticles made with lithium, nickel, and manganese oxides.
First, the team took high-resolution images that clearly showed rows of atoms separated by channels filled with lithium ions. On the surface, they saw the accumulation of nickel at the ends of the rows, essentially blocking lithium from moving in and out.
To find out how the surface layer is distributed on and within the whole nanoparticle, the team used a technique called three-dimensional composition mapping. Using a nanoparticle about 200 nanometers in size, they took 50 images of the individual elements as they tilted the nanoparticle at various angles. The team reconstructed a three-dimensional map from the individual elemental maps, revealing spots of nickel on a background of lithium-manganese oxide.
The three-dimensional distribution of manganese, oxygen and lithium atoms along the surface and within the particle was relatively even. The nickel, however, parked itself in small areas on the surface. Internally, the nickel clumped on the edges of smaller regions called grains.
To explore why nickel aggregates on certain surfaces, the team calculated how easily nickel and lithium traveled through the channels. Nickel moved more easily up and down the channels than lithium. While nickel normally resides within the manganese oxide cornrows, sometimes it slips out into the channels. And when it does, this analysis showed that it flows much easier through the channels to the end of the field, where it accumulates and forms a block.
The researchers used a variety of methods to make the nanoparticles. Wang said that the longer the nanoparticles stayed at high temperature during fabrication, the more nickel segregated and the poorer the particles performed in charging and discharging tests. They plan on doing more closely controlled experiments to determine if a particular manufacturing method produces a better electrode.

Google Maps, Now With More High-Res Satellite And 45? Aerial Imagery
Google Maps gets more awesome by the day. Earlier this week, the service started rolling out stunning underwater imagery- if you will, a seaview mode. Now Google took to the Google Maps blog to announces the inclusion of more high resolution images including a major build-out of 45-degree images. This update brings a lot of new data to the mapping service. Google Maps and Earth now features 17 cities and 112 countries and regions with high-resolution aerial and satellite imagery. In addition, 51 cities can now be viewed in a 45-degree mode including 37 cities in the US and 14 abroad (full list below). It's never been easier to burn a little time and escape from your cubical to a far away land.Source: http://feedproxy.google.com/~r/Techcrunch/~3/Pzpsxia-nos/

Luring engineers, math whizzes into the classroom
AUSTIN, Texas?? It was the first day of class, and Chris Costello?s instructions to a group of college students in a science building at the University of Texas-Austin were evoking giggles.
?Imagine you?re a third-grader,? Costello, a teaching assistant, told the class. ?What?s something that can fly??
?Superman!? one student called out. ?A bird,? said another. ?A fly,? a third shouted.
Next, Costello and the course instructor, Shelly Rodriguez, handed out worksheets and brightly colored safety scissors. The students cut out and folded origami ?helicopters? and set about throwing them in the air, noting how fast and in which direction they spun.

The lesson was the difference between independent and dependent variables in scientific experiments, a concept that most students in the class ? which included chemistry, biology and mechanical-engineering majors ? had mastered long ago. But the point was not for these college students to learn something new about variables; it was to help them decide whether they wanted to take their knowledge and pass it on.
Read more education analysis at The Hechinger Report?As math and science people, we don?t always see ourselves as teachers, but I hope you?ll keep an open mind,? said Rodriguez, who, like Costello, is a former high school teacher.
Her pitch was the first step in a special program at the University of Texas known as UTeach, an effort to entice talented math and science majors who might otherwise become doctors or engineers to choose teaching instead. It was developed in answer to a growing crisis in American education.
For more than a decade, educators have been sounding an alarm about the dismal performance of American students in math and science. They cite grim statistics: Less than a third of eighth-graders scored proficient in science on the National Assessment of Student Progress in 2011 and slightly more than a third passed on math.
U.S. sinking in science, technology
As a result, the United States is also quickly losing its status as a world leader in science and technology, according to a landmark report published in 2005 by The National Academies, a nonprofit research group. China, South Korea and France now far outstrip the United States in the percentage of their students graduating with engineering or science degrees (as many as half compared to 15 percent in the U.S.).
This summer, the Obama administration announced plans to create a new master teaching corps in science, technology, engineering and math, known as STEM studies. Educators, along with the Obama administration, are also increasingly embracing UTeach, which has spread to 34 universities in 16 states. In the 2005 National Academies report, UTeach was cited as a model that could ?transform the quality of our science and mathematics teaching.? Last year, Congress passed the America COMPETES Act, which includes funding to replicate the UTeach model in other universities.
UTeach was conceived in 1998, when a group of high school teachers and professors at the University of Texas-Austin gathered to discuss what to do about the state of STEM education in local schools. Although occasionally college professors and students would visit local K-12 classrooms to teach a lesson or two, these were ?not durable solutions,? recalls Michael Marder, a physics professor at the university.
?There are large (teacher) shortages? in math and science classes in high school, Marder said. ?This was clearly a place where the university was well-placed to make changes.?
Mary Ann Rankin, then dean of the university?s College of Natural Sciences, invited the high school teachers to come up with their ideal program for training new math and science teachers ? the kind they wished they had before entering the classroom. Professors from both the education school and from the math and science departments then tweaked that curriculum.
Fewer lectures, more student-led work
The result was a series of courses that combine practical teaching experience ? before committing to the program, students must teach lessons at a real school to see if they like it ? with educational, mathematical and scientific theory.
?We wanted to change it so they weren?t taking generic education classes, but what ? you need to teach math and science,? said Mary Walker, a former high school chemistry teacher who helped design the UTeach curriculum.
Traditionally, education colleges have trained math and science teachers, in contrast to the partnership between the math, science and education faculties in the UTeach program. The curriculum is intense, but also relatively condensed, mainly because UTeach students spend more time teaching rather than observing.
Education Nation: Read more and make your voice heardThe curriculum is heavily focused on inquiry-based teaching, which means fewer lectures and more student-led group work, like the helicopter exercise, and long-term projects.
Administrators say the program has exceeded expectations. Between 2000 and 2011, 702 students graduated from the UT-Austin program (only nine students graduated in the first cohort). The total national enrollment in UTeach programs is now 5,500. And more than 80 percent of alumni are still in the classroom after five years ? an impressive number considering that half of teachers nationally leave the profession in that period.
Most importantly, some evidence suggests that UTeach alumni are improving the performance of their students, administrators say.
Newcomers carefully observed
UTeach administrators observe new teachers once they enter the classroom, says Marder, who is now co-director of the program. The program has not yet published the results, though. ?We?re working to gather that data,? Walker said.
Schools in Austin, where UTeach alumni make up 20 percent of math and science teachers, have seen big improvements in those subjects, however, which may have something to do with the program?s efforts.

Luring engineers, math whizzes into the classroom
Manor New Tech High School, in a small town just east of Austin, offers more evidence that the program can improve student achievement. The school opened in 2007 with a math and science faculty comprised entirely of UTeach alumni. So far, the school has performed above average on state math and science tests and graduated nearly all of its students, the majority of whom qualify for free- or reduced-price lunches available to low-income students. And 100 percent of those who graduate go on to college, says the principal, Steven Zipkes.
?We have more room to be creative. I like that we?re allowed to do independent work,? said Dharma Casey, a 14-year-old freshman in a biotechnology class taught by UTeach alum Stephanie Hart. It?s a sharp contrast to her middle school experience, she added. ?We did a lot of stuff out of the book last year.?
It?s UTeach?s focus on making discovery and creativity integral to the study of math and science that has drawn in many new teachers who might have gone on to more prestigious or better-paid jobs. Janice Trinidad, a teacher at Manor New Tech who has a Ph.D. in physics, says her own education was mostly lecture classes that were ?very teacher centered.?
?There are some students in this school who wouldn?t have survived the way I was taught,? she said.

Facebook stops asking you to snitch on your friends
1 day
Earlier this week, the Internet had a mini meltdown over false reports that Facebook may?ve posted users' old?private messages.
Though it was swiftly deemed untrue,?even the French government demanded answers on this non-scandal. All of that overshadowed the real news, a creepy misstep of which the world?s largest social network really?is guilty: asking Facebook users to identify friends who may be using fake names on the site.
?Help Us Make Facebook Better,? read a survey prompt that kicked up a comparatively minor amount of ire when it made the rounds on Twitter. ?Is this your friend?s real name?? the survey went on, showing a photo of one of the recipient?s Facebook friends and multiple choice answers, ?Yes,? ?No,? ?I don?t know this person,? and ?I don?t want to answer.?
?Your response is anonymous and won?t affect your friend?s account,? Facebook assured on the poll question, which Facebook representive?Fred Wolens reiterated to NBCNews.com.?
Though Facebook does have a real name policy, Wolens said this particular poll was one of many anonymous surveys Facebook uses to tweak its algorithms. He provided the following company statement:?
This was a limited survey we have already concluded. We are always looking to gauge how people use Facebook and represent themselves to better design our product and systems. We analysed these surveys only using aggregate data and responses had zero impact on any user's account.
According to Wolens, the survey was received by a small amount of users. Exactly how small, he wouldn?t say. News of it?spread when?Twitter user @chapeaudefee tweeted a screenshot and the comment, ?Facebook wants to know if your friends? names are real. Are you going to be the snitch??
Outraged? Probably. You know how you love to be outraged at Facebook. Shocked? Not so much.?
The Internet is currently so unperturbed by this latest turn, YouTube has yet to produce a single ?Hitler reacts to Facebook asking you to snitch on your friends? video ? though a long history of totalitarian regimes asking its citizens to turn on their neighbors is not lost on those who are offended by the poll, despite its reassurances.
?The whole idea of snitching is highly dodgy,? writes privacy blogger Paul Bernal.??It?s creepy ? and it helps build at atmosphere of distrust, breaking down the very things that make social networks good,? he continues. ?The social relationships that are the heart of Facebook are meant to do ?good? things ??not be a route by which bad things are spread.?
--?via Sophos
Helen A.S. Popkin goes blah blah blah about privacy?and then asks you to join her on?Twitter?and/or?Facebook. Also,?Google+.?Because that's how she rolls.

Tesla unveils network of free, solar 'Superchargers' for Model S
22 hrs.
Tesla Motors has answered critics of the range and energy source of electric cars by establishing a network of solar-powered charge stations throughout California, with plans to expand to the rest of the U.S. And if you have a Model S, charging is free forever.
For years it has been an oft-repeated objection to electric cars that while they may not themselves produce carbon emissions, their electricity often is produced by carbon-producing power plants. It's a legitimate problem, though for now unavoidable ? unless, as Tesla demonstrates, you circumvent the power grid altogether.
That's what they've decided to do with their Supercharger stations, a network of solar-powered chargers that will refill your Tesla Model S free of charge. And what's more, they charge at four or five times the rate of even a high-capacity home charger, so you can get 150 miles of range back in half an hour.?
The Superchargers aren't intended for everyday charging, but for long-distance driving: they're?spaced between 100 and 200 miles apart, distant but?well within the 250-mile range of the Model S. At the moment the network is limited to California, but Musk was confident that within two years, much of the U.S. (as well as some of Europe and Asia) will be covered:
As Tesla CEO Elon Musk said at the announcement, "If you want to go from LA to New York, if you pack food and stay with friends, you can leave your wallet at home."
The other nice thing about these stations is that not only do they power themselves, but they're designed to collect more solar energy than they expend on charging vehicles. This extra energy they actually contribute to the grid, so they're a net positive, not a draw.
Tesla's Model S is their newest vehicle, aimed at commuters and families. At around?$50,000 to start, it competes with Lexus and BMW, not Honda and Subaru, but that hasn't stopped it from pre-selling thousands of units. They're only just this month starting to roll out to buyers, so there aren't many on the road just yet.
The Supercharger stations in and around Los Angeles and San Francisco are online?right now, and others will surely be announced by Tesla when they go live. More information can be found at Tesla's press release, and?Engadget has embedded a video of the event.
