5 Ways Teachers Can Evaluate Educational Games

Dr. David Dockterman is chief architect, learning sciences at Scholastic Education and an adjunct lecturer at the Harvard Graduate School of Education. He is an educational software pioneer and has designed dozens of award-winning instructional technology programs.

A recent Joan Ganz Cooney Center survey of 500 educators found that half of all kindergarten through eighth grade teachers are now regularly using digital games in the classroom. Nearly one in five are using them every day. It?s clear that in the age of the iPad, digital games are opening up a world of new possibilities for teaching and learning, and for increasing engagement in the classroom. But teachers must be reassured that the games they are using are connected to instructional goals.

As part of my work to develop educational math games, we established a process for creation and educational integrity. Here are the five areas we evaluated that teachers can also consider when trying to determine what games to offer their students.


1. Define the Learning Objective


For the math games we started with the Common Core State Standards (CCSS) for Math. Specifically, we looked at what math students need to know well by the end of third grade. The standards ask students to know how to identify any unknown in a math problem (3x4=? or ?x4=12 or 12??=3) and to be able to solve a math problem that uses multiples of 10 (3x4=12 or 30x4=120).

[More from Mashable: Hey Soon-to-Be Facebook Millionaires: Read This]

Sadly, research shows that many students don?t achieve these fundamental third-grade fluencies, even as they enter middle school and high school. To address this issue we created a learning objective: Build student speed and accuracy with different combinations of addition and multiplication problems, as well as computations with multiples of 10.


2. Describe the Learning Mechanic


The learning mechanic represents the actions we want students to take that will reinforce the learning objective. If our primary learning objective, for instance, is improved speed and accuracy, then we might want the learning mechanic to include an element of time.

In our case, we wanted students to make choices about different combinations of numbers. We determined that a fixed pool of options would be the best way to push that decision-making process so we opted for a count-up timer rather than a countdown timer. This let the students take as long as they needed to figure things out. As they get better, they?ll see their times decrease.


3. Imagine What Students are Thinking


This element of the design might be the most critical. What do we want going through students? heads as they are playing the game? Is it a quick retrieval process? 80 + 70 is 150. Got it. Is it about recognizing a pattern? If 10 x 30 is 300, then 100 x 30 must be 3,000. We use this articulation as a test against the final game design to make sure the child tester is thinking those targeted thoughts.

4. Pick a Game Mechanic


What?s the difference between a learning mechanic and a game mechanic? It's important to the know the difference. Professional game designers have a lexicon for gaming elements that?s incredibly robust. They look at a learning mechanic of, for example, selecting the correct objects from a pool to match a target and come up with dozens of games built around that action. The games might include timers and a goal of clearing a board. Or they might involve collecting as many matches as possible while avoiding unwanted objects. We chose a clear-the-board game mechanic as the central focus.

5. Create a Theme Where the Mechanic Can Exist


Clearing the board can happen anywhere. It can be a somewhat familiar space, like an arcade where you pop balloons with a BB gun or a dirty floor where you mop up selected tiles. On the other hand, the space where the learning action occurs can be inventive and strange. Angry Birds being catapulted into space is not based on a familiar and real setting. It?s invented, and its originality is part of the draw.

The early prototypes of our game were called ADDitude and MULTItude. We had completed steps one through four. The games worked from a mathematical perspective and our student testers seemed to enjoy them. They were thinking the thoughts we wanted them thinking. However, we wanted more engagement, and a bit of whimsy to bring a smile along with mathematical challenges. Our creative artists threw out a bunch of wacky ideas. The great game designers at BlockDot also helped. One crazy notion led to another, and somehow we ended up with the game, Sushi Monster.

What does sushi have to do with arithmetic? Nothing, but it also doesn?t interfere with the math tasks. Sustaining the learning objective, mechanic, and thought processes are the driving forces of our development. Everything is subservient to those first three steps. We?re working to build educational games, not games with some education tacked on. Keep that in mind as you look at the educational game options for your students and children.

Former 'revenge porn' czar under FBI investigation: report

5 hrs.

"Revenge porn" is how the content of Hunter Moore's website, Is Anyone Up, is most always described.

Defunct since April, Is Anyone Up invited bitter ex-lovers to submit nude photos and videos of their former partners, along with that former partner's Facebook profile or other social media identity. This added burn allowed for the added humiliation of Google search results, and the possibility of further online harassment.?Thing is, many of those photos weren't submitted by a cadre of spurned lovers, but a single hacker. Now the FBI wants to know if ?Moore is connected to that hacker.?

According to?the?Village Voice:

The Voice has learned that the FBI's Los Angeles Internet Crime division has been actively investigating Hunter Moore and Is Anyone Up for months, according to four people who say they've been interviewed by the FBI about his now-shuttered site. The case's focus, according to those familiar with the investigation, was Moore's possible connection to a hacker who has repeatedly broken into the inboxes of countless victims, rifled through their attachments, and submitted the accompanying nudes to Is Anyone Up. (A Los Angeles FBI spokesperson would not confirm or deny such an investigation.)

When we contacted the FBI directly, the spokesperson said the same thing, that the bureau could neither confirm nor deny the Hunter Moore investigation.

Moore, who sold Is Anyone Up to a for-profit "anti-bullying" website last month, operated his site for 16 months, seemingly under the protection of The Communications Decency Act of 1996. According to the Act, Internet service operators ? Facebook and the like ? are not considered the publishers of user posts, and so not liable for content that breaks the law. A connection with the hacker could cause Moore's fortunes to turn, however. As the Voice notes, Chris Chaney, the guy who hacked Scarlett Johansson and other celebrities, faces 60 years in prison and $2.25 million in fines.

Moore?said?he sold Is Anyone Up because he was burnt out on child porn submissions and ruining people's lives. He seems a mite sensitive about the FBI investigation however, telling the Voice's Camille Dodero that he would burn down the publication's offices if it wrote about his FBI investigation.?In the past, Moore readily admitted that many of the user submissions may be the product of hacks, but continually claims that even if he paid for the content, he's still untouchable. Looks like his claim is about to get tested.?

Helen A.S. Popkin goes blah blah blah about online privacy, then asks you to join her on?Twitter?and/or?Facebook. Also,?Google+.?Because that's how she rolls.

When Teenagers Experience Male-Pattern ... - News and Society

While male-pattern baldness primarily occurs in adult men, there are instances when teenage boys can experience the disorder. It can be highly traumatic for a teenager to begin losing his hair. They can be obsessively focused on their appearance to begin with and going bald can add to this already stressful situation. They will want to seek immediate medical assistance to stop the condition from worsening.

When to be Concerned

Hair loss is not uncommon. In fact, everyone loses up to 100 head hairs every day. This is a natural process that involves old hair falling out to make room for new hair. It is not a cause for alarm. But if you are losing more than that or your hair seems to be coming out in clumps, you need to see a doctor to make sure there is nothing seriously wrong. Underlying medical conditions can cause hair loss in teenage boys.

Causes of Hair Loss in Teenagers

Teenage boys can experience hair loss for a variety of reasons. A common culprit is scalp ringworm which is a contagious infection that can cause permanent hair loss. Certain hairstyles or styling routines such as braiding or dyeing the hair can also result in hair loss in teenagers. The most challenging to treat is male-pattern baldness which has been known to develop in teenage boys by age 15.

Types of Hair Loss Treatment

The cause of the hair loss determines the appropriate treatment regimen. The most popular treatment for male-pattern baldness is with oral medications known as 5-alpha reductase inhibitors. These drugs effectively stop the production of a particular hormone that interferes with hair growth. Results range from stopping hair loss to actual hair regrowth. There are many factors that determine the effectiveness of a treatment on a particular patient.

Seeking Treatment

Looks are important to all teenagers. Because of the impact on their self-esteem, teenagers are more likely to seek medical attention for hair loss sooner than their adult counterparts. Unfortunately, teens must be at least 18 years old to be treated with propecia. Hair loss concealers that cover the balding area may be a temporary option until teenagers are old enough for medical treatment.

This article looks at how male-pattern baldness can impact teenagers who seek medical assistance but cannot be prescribed propecia until they are eighteen. Fortunately, there are steps they can take to address their balding disorder.

Tips To Help You Fix Your Home While Keeping On Budget ? WWG ...

May 17, 2012

Tags: cleaning and tools, electrical, Food and Restaurant, home improvement, home repair, home upgrades, tools and equipments

Home improvement choices are somewhat personal in nature. If you will be living in your home for a long time, then you can make decisions about what you like the best. If you are selling within a relatively short period of time, then there are a lot of factors to take into account. This article will give you ideas on how you can make good decisions when it comes to your home-improvement projects.

If you are working on your home yourself, make sure to purchase high quality tools and supplies. It may cost more at the start, but will cost you less in the long run. Higher quality products last longer and survive general wear better. Tools can be expensive and you don?t want to have to replace them regularly.

Don?t throw out paintbrushes and rollers each time you use them! They can be cleaned and reused as long as you take care of them. Paint pans can be cleaned by letting them dry and then peeling off the paint. Don?t waste your money on pan liners as cleaning the pan itself is simple.

Before you start enjoying your backyard this summer it is a good idea to evaluate the condition of your deck. Check for rotting wood or holes and repair or replace the problem areas. You will be prepared for the summer and this will save you time and money in the long run.

Fix up the entrance to your house by giving it a new coat of paint and a new welcome mat. Your entrance plays an important role in how you welcome your guests into your home. Extra touches like an attractive welcome mat and a pretty potted plant by your entrance will create a positive impression on your visitors.

Home improvements can be a lot of fun when you do it yourself. Make them more enjoyable by having a positive attitude and enjoying the job along the way. Take before and after photos to show your friends and family what you did as the job progressed and feel the pride of doing it yourself.

Before removing and replacing old wood floors attempt to refinish them first. In many cases, the original wood flooring of your home has a great deal more value than if you were to replace it. At the same time, many wood floors can be refinished and look as new as ever with less cost than replacing the wood floors altogether.

Maintaining a level head and a drive for perfection during home remodeling can be a bit hard. There is a lot going on, and you have to be able to ?roll with the punches? so to speak. The ideas in this article have shown you how you can have a beautiful home without breaking the banks and showcase your own personal style while not killing your resale value.

Acer ships Aspire M5 Ultrabook to UK in June, Ivy Bridge and Kepler chips in tow

Image

Acer made something of a splash when it trotted out its Timeline Ultra series of Ultrabooks at CES; those waves are just now hitting the shore with a full-on release in the UK under a tweaked Aspire M5 name. Both the 14- and 15-inch models are now known to be packing Intel's Ivy Bridge-era third-generation Core processors, and the "dedicated" video we heard about in January is NVIDIA's Kepler-based GeForce GT 640M, which we saw in the Timeline Ultra M3. Either new PC is still under 20mm (0.8 inches) thick with the option of an SSD, like the M3, but slapping the M5 badge on top means a much narrower display bezel, a backlit keyboard and other more upscale touches that show where your money's going. Picking the 15-inch model adds an optical drive along with a keypad for number-crunching. Mum's the word on exact specs and that all-important pricing, but those questions will be answered by the time the M5 hits British shops in mid-June. Now all that's left is to know when the new Aspire reaches the other side of the Atlantic.

Back pain relief may taper off | Health X Pert Articles-Health care ...

The Centers for Disease and Prevention released their annual health report for 2011 on Wednesday. The report contains more than 150 data tables on the U.S. population's well-being, with a special focus on socioeconomic status. Here are a few of the interesting tidbits we found. For more, visit www.cdc.gov . The Bible Belt needs more doctors. On average, there were 25 physicians for every 10,000 people in the U.S. in 2009. The Northeast, Hawaii and Minnesota had the highest ratio of doctors to patients, while states in the South and Rocky Mountain-areas had fewer than 21 per 10,000. Your education level affects your kids' weight. The CDC collected data on childhood obesity between 2007 and 2010. Where the head of the household had a college degree, 7 to 11% of children aged 2 to 19 were obese. But when the head of the household was a high school dropout, 22 to 24% of the children were obese. Cigarette smoking is still on the decline. In 2010, 19% of U.S. adults smoked, down 2% from 2009. Over the last decade cigarette smoking among students in 12th grade has decreased from 33% to 22% for male students and from 30% to 16% for female students. Fewer teens are giving birth. Between 1998 and 2008, birth rates declined 27% for teenagers between the ages of 15 and 17. The gap is widening in education? In 2006, men without a high school diploma were expected to live 9.3 years less than those with a Bachelor's degree. The difference is two years more than it was in 1996. A similar gap increase holds true for women. ? and narrowing in racial disparities. While the gap between life expectancy rates for African Americans and whites still exists, the gap has narrowed over the last two decades. Hispanics still have higher life expectancies than both ethnic groups. We're getting better at getting check-ups. In 2010, 59% of people over the age of 50 underwent a recent colorectal test or procedure, compared to 34% in 2000. Heart disease is still the No 1. killer. In 2008, 617,000 people died from heart disease-related causes. The prevalence among adult men and women has remained fairly steady for the last decade. Our children are fat, but not getting fatter. In 2010, approximately one in every five children was obese. Yet that rate has stayed pretty steady since 2007. That year, 19.6% of children aged 6 to 11 were obese. In 2010, it was 18%. Most people aren't moving enough. In 2010 more than half of American adults failed to meet the government's recommended daily physical activity levels. It was worse for the elderly ? approximately 70% of those over 75 didn't meet the requirements.

Ford Trade Update: Expect Further Downside As The Stock Approaches $10

My last trade recommendation on Ford (F) was to continue shorting or holding puts from the $11.20 area.

So far, thanks to further deterioration in the euro crisis, Ford has continued it's steady downtrend towards $10 per share.

Here is a look at the updated chart:


(Click to enlarge)

This time, I've added the 100 DMA to show the recent bearish cross of the 50 DMA under the 100 DMA. Despite RSI showing an oversold indication, the stock has continued to move lower, with only moderate bullish retracements.

As I noted in the last recommendation, absolutely nothing has indicated any sort of support for the stock. For those who believe the P/E is "too cheap," I'd like to point out once again that based on my earnings prediction of about $1.25 for fiscal 2012, the stock will be trading at 9 times earnings; a healthy valuation for a classic cyclical approaching the end of its cycle.

Last year, the stock didn't stop its rather violent downtrend until $9. With (more) rumors of an imminent Greece exit from the euro beginning to swirl again, Ford's status as a consumer and credit dependent cyclical is once again likely to lead the stock significantly lower in the intermediate term.

A Greek exit could cause a complete lack of confidence in the European periphery (i.e. Spain and Italy), resulting in huge bank failures and a potential systemic crisis. With credit fueling a large bulk of consumer car purchases, further market fragility or a general crisis will result in weaker consumer spending and fewer materialized sales. Not to mention, Ford may have to shut down several European operations in order to reduce variable costs.

For those waiting for an entry point, wait for longs to absolutely capitulate, or wait until some signs of a bottom start appearing. The market as a whole is currently undergoing a major turning point, so entry here is a pretty poor gamble.

Getting news from the Internet not as divisive as many assume

University of Illinois at Urbana-Champaign

CHAMPAIGN, Ill. The Internet is changing the way people get their news, but there's little proof that it is fragmenting or polarizing the news audience the way many assume, says professor David Tewksbury, the head of the University of Illinois department of communication.

"Many things that we thought were going to be really horrible have not yet happened," Tewksbury said.

Five years ago he was very worried. He feared the wide-open choice the Internet provided would encourage people to put on "intellectual blinders."

They would personalize their news habits and pay attention only to what they cared about, ignoring other news, especially about government and public affairs, he thought. They would be shaped by highly segmented and opinionated news sources.

But that was before he reviewed the research to co-write "News on the Internet: Information and Citizenship in the 21st Century," with former Illinois doctoral student Jason Rittenberg. The book was published recently by Oxford University Press.

The research does suggest that maybe half of online news consumers are very selective in what they follow, with more than half of those focused on sports, Tewksbury said. But the other half are seeking out a broad cross-section of news, which is better than what he and other researchers believed and feared, and in keeping with how people read newspapers.

"We don't have a lot of evidence that public affairs knowledge is going down because of audience fragmentation," Tewksbury said. "Many people know quite a bit about what's going on. They are attending to news in a relatively uniform fashion. It's not as if everyone has suddenly become more ignorant than they used to be."

Many previous books have looked at how online journalism gets done, and others at how audiences consume online news, Tewksbury said, but he and Rittenberg tried to bring the two together and look at the larger picture.

"We're trying to cover a large territory with this book," Tewksbury said. "We integrate huge areas of research, where we're trying to talk about content and audiences and how they fit together."

The book also plays out a tension between the co-authors' perspectives, Tewksbury said. Rittenberg, in his late 20s, was focused more on the possibilities of the technology, including its benefits for democracy. Tewksbury, in his late 40s, was more concerned with how people interact with the technology. He was worried about factors that might be segmenting, fragmenting and polarizing the news audience and society.

One of his goals in the book, in fact, was trying to describe how those factors and trends might interact, Tewksbury said.

Most researchers "are taking just a bite out of what is really a big picture," rather than "nailing down all the parts of that picture," he said. They are jumping to conclusions, for instance, about how news preferences connect with or influence news consumers' views (that is, people who watch Fox News will believe A, and those who watch CNN will believe B).

Tewksbury instead sees it as a process. "We can talk about fragmentation and polarization as being sort of steps," he said.

"If you attend to a particular kind of content in a consistent fashion, you'll learn different facts than others in that consistent fashion, and you'll form opinions that are based on that difference in the facts," he said.

The problem in connecting the dots, however, is that it's usually not that clean and straightforward, Tewksbury said.

"The biggest problem here is that people choose, and the Internet is an environment that lets people choose, actively and all the time," he said. That makes determining how people might be polarized by their news choices a tough assignment.

Someone can watch a partisan news source and have opinions that match with its news, he said, "but we really have a hard time pinning down which came first. That is exactly where future research needs to go."

Getting news from the Internet not as divisive as many assume [ Back to EurekAlert! ] Public release date: 15-May-2012

CHAMPAIGN, Ill. The Internet is changing the way people get their news, but there's little proof that it is fragmenting or polarizing the news audience the way many assume, says professor David Tewksbury, the head of the University of Illinois department of communication.

"Many things that we thought were going to be really horrible have not yet happened," Tewksbury said.

Five years ago he was very worried. He feared the wide-open choice the Internet provided would encourage people to put on "intellectual blinders."

They would personalize their news habits and pay attention only to what they cared about, ignoring other news, especially about government and public affairs, he thought. They would be shaped by highly segmented and opinionated news sources.

But that was before he reviewed the research to co-write "News on the Internet: Information and Citizenship in the 21st Century," with former Illinois doctoral student Jason Rittenberg. The book was published recently by Oxford University Press.

The research does suggest that maybe half of online news consumers are very selective in what they follow, with more than half of those focused on sports, Tewksbury said. But the other half are seeking out a broad cross-section of news, which is better than what he and other researchers believed and feared, and in keeping with how people read newspapers.

"We don't have a lot of evidence that public affairs knowledge is going down because of audience fragmentation," Tewksbury said. "Many people know quite a bit about what's going on. They are attending to news in a relatively uniform fashion. It's not as if everyone has suddenly become more ignorant than they used to be."

Wajam Brings Its Enhanced Social Search Results To Bing and Yahoo

Wajam_logoAs all the major search engines continue to add social search features to their feature line-up, it can often look as if there isn't any space left for startups in this space. Wajam begs to differ. The Montreal-based company is probably one of the most ambitious players in the social search market right now and after launching its latest efforts for Google last month, it is now ready to bring its enhanced social search results to Bing and Yahoo as well.

Thunderbolt on Windows gets hands-on, lacks Mac's hot-swapping

Thunderbolt on Windows gets hands-on, lacks Mac's hot-swapping

Thunderbolt's 10-gigabit interface is only just making its way to Windows after spending more than a year as a Mac-only feature, so it's not surprising that a lot of questions surround how well the Apple- and Intel-developed connection works for those of a Microsoft persuasion. A thorough test at AnandTech of one of the first motherboards to support the spec on Windows PCs, an Ivy Bridge-ready board from MSI, has shown some positive signs along with a few flies in the high-speed ointment. The good news? Most general storage devices will work as expected with a minimum of fuss, and you can even get some features of Apple's Thunderbolt Display working if you're willing to accept a lack of pre-supplied software brightness controls and USB support. The bad news comes mostly in the absence of true hot-plugging like on the Mac: if a device isn't plugged into the Thunderbolt port on boot, Windows won't see it. Professionals who need everything to be just perfect will want to wait, then, but bandwidth lovers will still find something to like if they're willing to build Thunderbolt-equipped PCs themselves.

Tesla coil gun exists, may shoot lightning

Tesla coil gun exists, may shoot lightning

Inspired by the graphic novel "Five Fists of Science" -- and perhaps encouraged by the plucky MIT student who made his own Tesla coil hat and survived -- a DIYer named Rob designed a Tesla coil gun, which he says is fully functional. Rob used a Nerf gun cast in aluminum for the housing and created a high voltage switch with a 3D powder printer. The gun is powered by an 18V ion drill battery and a flyback transformer housed inside a PVC plumbing end cap. Though Rob has yet to fire the gun, photos show what he says are sparks from the setup, and a demo clip is on the way. While video proof is always nice, so is preserving your life. We wish Rob the best with both.
