Is it possible to create suitable and amusing educational computer games? Can you use qualities from other types of games? And what do the children really think of these kinds of games? Wolmet Barendregt from The University of Gothenburg, conducts research on children's game playing, how we can support learning with design and include the children in the design process.

And Wolmet Barendregt certainly involves the children very much in her research. During the Science Festival's school program in April this year, over a hundred preschool children attended a creative game workshop to evaluate the game Fingu. Fingu is a mathematical game for iPad where players use their fingers to get a feel for the numbers and thus a better understanding of them.

Working with children is both fun and challenging because you never know what will happen, says Wolmet. It is difficult to find suitable methods to use for children when evaluating. Children cannot verbalize, but they can draw. At the Science Festival, we tested a method of evaluation, Drawing Intervention, which some researchers advocate for children because they do not have to verbalize. Wolmet Barendregt however recognizes that it is problematic to know how much you influence yourself in what you say during the instructions and how much the different groups affect each other when they are in the same room. The children's past experiences, what other games they have played, certainly affects the outcome as well.

There were two main things that we learned about Fingu while testing this method. Curiosity and imagination could be improved, she explains.

Well, the kids think that some are funny, Wolmet answers. Many games are about solving tasks, and then the developers have added stuff around it so that it resembles a game. Sometimes the kids see through that.

Wolmet says that in Fingu focus is more on how children learn basic arithmetic using their fingers. She admits that there are some things to develop in order to create a really fun game and that the risk of so-called educational games in general is that they are either too educational and boring, or fun-filled but without any learning opportunities.

It's a fairly limited game and therefore may not encourage a lot of playing, but many children still play it several times. I have noticed that the interest in the game sometimes returns when the children realize that they have become better at certain things and therefore can reach higher levels, Wolmet says.

At a recent conference, "Interaction Design and Children", a conference focusing on children's needs and how to design for them, Wolmet Barendregt presented another study of Fingu and children playing the game where the analysis was of their development in the game. At the same conference Wolmet also presented a research project that studies how parents and children are playing so-called cooperative video games together where collaboration is necessary to get ahead in the game.

We have seen that game design affects the interaction between children and parents, especially when there is a difference in skills, something which is not uncommon. In some games, the player who is the best can help the other player who is not as good. In other cases, the player who is not so good restrains the more skilled player, and there are also games where both can explore things even if they are not euqally skilled, says Wolmet. We seek a deeper understanding of how different game design affects how you play together and what mechanisms can and cannot be used for educational games.

Sorting Out The Truth About Dieting From The Myths | Health ...

Losing weight can be a challenge, but with the right amount of will power and determination it can be done successfully. But exactly how do you sort out the truth from the welter of information which is available on dieting? For instance what about those how claim you should choose food that is low calorie but fills you up quickly, such as soups, salad or raw vegetables? Or those who argue you should fill up on low calorie drinks especially iced water?

One theory which has been the subject of much controversy in the past but which is gaining new momentum is that so called ?crash dieting? can help not only lose weight fast, but also help to keep it off long term. Previously, the perceived wisdom was that very low calorie diets such those espoused by Houston HCG Diet Clinics didn?t really work. Sure, the weight came off at the start, but you soon began to see it pile back on when you switched from the strict regime. However scientists in the UK have now produced evidence that very low calorie diets do in fact work and are effective both at helping achieve that initial weight loss AND in helping keep the weight off in the longer term

Rams rally in 2nd half, beat Redskins 31-28

ST. LOUIS (AP) ? Robert Griffin III had his moments. The St. Louis Rams, though, have what counts most of all ? a win.

Sam Bradford threw for 310 yards and three touchdowns and Danny Amendola caught 15 passes for 160 yards as the Rams rallied for a 31-28 victory over RG3 and the Washington Redskins on Sunday in their home opener.

"The dome was rocking and it should be in a couple of weeks when we get back," Amendola said. "It was a good game, it came down to the wire, came down to the last kick."

Steven Jackson sat out most of the last three quarters after drawing an unsportsmanlike conduct penalty for spiking the ball, but coach Jeff Fisher said it was because Jackson had a groin strain and not because he'd lost his cool.

"It had nothing to do with the spike," Fisher said. "His groin was real tight and we just didn't want to subject him to it. I didn't think he'd be 100 percent."

Jackson said he thought he'd be able to re-enter the game but said the groin tightened on him.

Griffin led the Redskins (1-1) to a 21-6 lead, but the Rams came back thanks to the pass-catching of Amendola. The receiver tied an NFL record 12 first-half receptions, and caught a 1-yard TD pass to cut the lead to 21-13 at the half.

Amendola was out virtually all of last season after dislocating his left elbow making a cut in the opener.

"Obviously it's nice to have him back out there on the field," Bradford said. "He's a tremendous player. We knew going into this game that we were going to try to get him the ball."

Bradford had second-half scoring passes of 34 yards to Brandon Gibson and 1 yard to Matthew Mulligan.

Griffin ran for two touchdowns and passed for a third for Washington (1-1).

The Redskins got a final shot after DeAngelo Hall recovered running back Daryl Richardson's fumble at the Washington 37 with 2:40 to go. Josh Morgan was called for unsportsmanlike conduct for throwing the ball Rams cornerback Cortland Finnegan after a 7-yard catch on 3rd-and-8 to the Rams 29, leaving the Redskins with 4th-and-16.

Shanahan called for a 62-yard field goal attempt, and Billy Cundiff was wide right and well short with 1:13 to go.

"It might have been the first down, it was close enough, it was inches," Shanahan said. "You can't lose your poise. You lose your poise, obviously good things don't happen."

Shanahan thought Cundiff had a shot, reasoning "he kicks the ball out of the end zone" on kickoffs form the 35. Griffin was disappointed, but he understood.

"I thought we were going for it," Griffin said. "But in a dome, 62 (yards) is far, but it's not that far. I was on a knee and I hoped that it would go through."

The Rams took the lead on Bradford's TD pass to Mulligan on the first play of the fourth quarter, and Richardson ran it in on a 2-point conversion for a 24-21 lead. Mulligan had partially blocked Sav Rocca's punt to give the Rams the ball at the Washington 24 four plays earlier.

Griffin, who looked like a veteran in his NFL debut last week in leading the Redskins to a win over New Orleans, scored on runs of 5 and 7 yards. He also threw a 68-yard touchdown pass to Leonard Hankerson.

Jackson spiked the ball after getting ruled short of the goal line on a third-down carry from the 1. It came a play after the Rams successfully challenged a lost fumble call on Jackson.

After that, the franchise's career leading rusher left, and spent most of the rest of the game by himself on the sideline with his helmet in hand.

Amendola had a rough start, fumbling after a 13-yard catch on the Rams' first snap, with Josh Wilson returning it 30 yards for his fifth career defensive touchdown. He recovered nicely, matching the first-half NFL record set by the Colts' Reggie Wayne in 2007, while tying his career best game total in the process and setting a personal game-best with 133 yards receiving.

The Redskins lost defensive end Adam Carriker and outside linebacker Brian Orakpo to injuries early in the first quarter, while Rams offensive tackle Rodger Saffold was helped off with a right knee injury.

Orakpo and Saffold were hurt on the same play. Orakpo stripped Bradford and Saffold recovered the fumble and carried it 7 yards, but crumpled to the turf on the tackle.

NOTES: The game was chippy throughout with several skirmishes, especially in the first half with Redskins LB London Fletcher called for a personal foul on a sideline hit on Amendola and the Rams' Eugene Sims whistled for hitting Griffin, who appeared to be turning up the field and not running out of bounds. ... Amendola tied the franchise single-game record shared by Isaac Bruce and Flipper Anderson. ... Bradford passed for 300 or more yards for the fourth time in his career and threw for three TDs for the second time. ... Rams rookie punter Johnny Hekker averaged 54.3 yards on three attempts.

US doping agency erases Lance Armstrong's titles

His seven Tour de France titles stripped away and his legacy in tatters, Lance Armstrong is heading back outdoors and into the public eye.

A day after the U.S. Anti-Doping Agency punished Armstrong with a lifetime ban from professional cycling and erased 14 years of his career after concluding he used performance-enhancing druugs, Armstrong is scheduled to ride in a mountain bike race in Aspen, Colo., on Saturday and follow it up by running a marathon there Sunday.

And he has no plans to slow down any time soon, despite the whirlwind of controversy swirling around him.

Armstrong spokesman Mark Higgins said Armstrong also still plans to attend the World Cancer Congress in Montreal where's he scheduled to deliver a keynote address to thousands in attendance.

"He's getting out there," Higgins said.

Anti-doping and cycling officials will continue to address his career.

USADA said Friday it expects cycling's governing body to take similar action, but the International Cycling Union was measured in its response, saying it first wanted a full explanation of why Armstrong should relinquish Tour titles he won from 1999 through 2005.

The Amaury Sport Organization, which runs the world's most prestigious cycling race, said it would not comment until hearing from the UCI and USADA. The U.S. agency contends the cycling body is bound by the World Anti-Doping Code to strip Armstrong of one of the most incredible achievements in sports.

Armstrong, who retired a year ago and turns 41 next month, said Thursday he would no longer challenge USADA and declined to exercise his last option by entering arbitration. He denied again that he ever took banned substances in his career, calling USADA's investigation a "witch hunt" without any physical evidence.

USADA chief executive Travis Tygart described the investigation as a battle against a "win-at-all-cost culture," adding that the UCI was "bound to recognize our decision and impose it."

"They have no choice but to strip the titles under the code," he said.

That would leave Greg LeMond as the only American to win the Tour de France, having done so in 1986, 1989 and 1990.

LeMond did not immediately respond to messages requesting comment left through his attorneys and friends.

Armstrong on Friday sent a tweet about his plans to race in Aspen, but did not comment directly on the sanctions.

The UCI and USADA have engaged in a turf war over who should prosecute allegations against Armstrong. The UCI even backed Armstrong's failed legal challenge to USADA's authority, and it cited the same World Anti-Doping Code in saying that it wanted to hear more from the U.S. agency.

"As USADA has claimed jurisdiction in the case, the UCI expects that it will issue a reasoned decision" explaining the action taken, the Switzerland-based organization said in a statement. It said legal procedures obliged USADA to fulfill this demand in cases "where no hearing occurs."

If Tour de France officials follow USADA's lead and announce that Armstrong has been stripped of his titles, Jan Ullrich could be promoted to champion in three of those years. Ullrich was stripped of his third-place finish in the 2005 Tour and retired from racing two years later after being implicated in another doping scandal.

The retired German racer expressed no desire to rewrite the record book of cycling's greatest event, even though he would be the biggest beneficiary.

"I know how the order was on the finishing line at the time," Ullrich said. "I've finished with my professional career and have always said that I was proud of my second-place finishes."

The International Olympic Committee said Friday it will await decisions by USADA and UCI before taking any steps against Armstrong, who won a bronze medal at the 2000 Sydney Games. Besides the disqualifications, Armstrong will forfeit any medals, winnings, points and prizes, USADA said, but it is the lost titles that now dominate his legacy.

Every one of Armstrong's competitive races from Aug. 1, 1998, has been vacated by USADA, established in 2000 as the official anti-doping agency for Olympic sports in the United States. Since Armstrong raced in UCI-sanctioned events, he was subject to international drug rules enforced in the U.S. by USADA. Its staff joined a federal criminal investigation of Armstrong that ended earlier this year with no charges being filed.

USADA said its evidence came from more than a dozen witnesses "who agreed to testify and provide evidence about their firsthand experience and/or knowledge of the doping activity of those involved in the USPS conspiracy," a reference to Armstrong's former U.S. Postal Service cycling team.

The unidentified witnesses said they knew or had been told by Armstrong himself that he had "used EPO, blood transfusions, testosterone and cortisone" from before 1998 through 2005, and that he had previously used EPO, testosterone and Human Growth Hormone through 1996, USADA said. Armstrong also allegedly handed out doping products and encouraged banned methods ? and even used "blood manipulation including EPO or blood transfusions" during his 2009 comeback race on the Tour.

In all, USADA said up to 10 former Armstrong teammates were set to testify against him. Had Armstrong chosen to pursue arbitration, USADA said, all the evidence would have been available for him to challenge.

"He chose not to do this knowing these sanctions would immediately be put into place," the statement said.

Armstrong said he has grown tired of defending himself in a seemingly endless fight against charges that he doped while piling up more Tour victories than anyone. He has consistently pointed to the hundreds of drug tests that he passed as proof of his innocence during his extraordinary run of Tour titles.

"There comes a point in every man's life when he has to say, 'Enough is enough.' For me, that time is now," Armstrong said Thursday night, before the deadline to enter arbitration.

His success helped sell millions of the "Livestrong" plastic bracelets and enabled him to promote cancer awareness and research, raising nearly $500 million since his Lance Armstrong Foundation was started in 1997.

Foundation officials said they remained "proud" of Armstrong and had received hundreds of messages of support from donors, partners and supporters since his announcement. Among them was Nike Inc., which said it planned to continue supporting Armstrong and the foundation.

"Lance has stated his innocence and has been unwavering on this position," the company said.

Anheuser-Busch said its partnership with Armstrong was unchanged. American Century Investments, another partner, issued a statement supporting him.
