Education specialists argue that ILSA scores should not be used to conduct

first_img As the authors note, ILSAs such as PISA and TIMSS have, in recent years, become a tool for nationalistic bragging among those with high scores—those with lower scores are more often scorned. But, they note, using ILSA scores in such a way offers little in the way of educational improvement, which is the generally accepted purpose of testing students. They also note that there is a danger in over-interpreting such scores because it can have a dramatic negative impact on education policy. There is a problem, they point out, when journalists and politicians use ILSA test scores as means to serve their own ends rather than to champion the goals of educating the world’s children—it can skew how people view their country’s education system.Ranking ILSA score results by country, the authors note, is quite misleading—instead of offering a fair assessment of academic abilities, such lists instead offer little except headlines or web clicks. They also note that the rankings do not always give an accurate portrayal of academic achievement—some countries jump around on the list from year to year, for example, without making any changes. Others skew their own results by hiding low-scoring students. They note also that there are vast differences in how hard students try to do well on such tests—for many students in places like Korea or Japan, scoring high on an ILSA is so important that parents spend hours helping them prepare, or spend thousands on tutors. Meanwhile, in places like the U.S., students see little advantage in preparing at all.The authors suggest that all countries view results on ILSAs as a means of learning more about their own system and in so doing discover ways that their own educational systems can be improved.

In their paper, Judith Singer and Henry Braun point out problems with comparing ILSA results between countries and suggest they could be put to better use by local entities looking to improve their education systems. More information: Judith D. Singer et al. Testing international education assessments, Science (2018). DOI: 10.1126/science.aar4952SummaryNews stories on international large-scale education assessments (ILSAs) tend to highlight the performance of the media outlet’s home country in comparison with the highest-scoring nations (in recent years, typically located in East Asia). Low (or declining) rankings can be so alarming that policy-makers leap to remedies—often ill-founded—on the basis of what they conclude is the “secret sauce” behind the top performers’ scores. As statisticians studying the methods and policy uses of ILSAs (1), we believe the obsession with rankings—and the inevitable attempts to mimic specific features of the top performing systems—not only misleads, it diverts attention from more constructive uses of ILSA data. We highlight below the perils of drawing strong policy inferences from such highly aggregated data, illustrate benefits of conducting more nuanced analyses of ILSA data both within and across countries, and offer concrete suggestions for improving future ILSAs.last_img read more

Eat homemade food to cut diabetes risk

first_imgEating meals prepared at home may reduce the risk of developing type-2 diabetes, a recent study reveals.Eating fast food from restaurants is associated with lower diet quality and higher body weight in children and young adults and is also a major risk factor for heart disease, according to the researchers.“The trend for eating commercially prepared meals in restaurants or as take-out in the US has increased significantly over the last 50 years,” said Geng Zong from Harvard TH Chan School of Public Health in Boston, Massachusetts. Also Read – ‘Playing Jojo was emotionally exhausting’People who ate two homemade meals each day, or about 11-14 meals a week, had 13 per cent lower risk of developing type-2 diabetes compared to people who ate less than six homemade meals a week. The study included nearly 58,000 women and more than 41,000 men up to 36 years from 1986-2012. None of the participants had diabetes, cardiovascular disease or cancer at the beginning of the study.The researchers demonstrated that eating homemade meals was associated with less weight gain over eight years in these middle-aged and older health professionals. The research was presented at the American Heart Association’s Scientific Sessions recently in 2015.last_img read more

Blast from the past Zamindar family Puja gives taste of a bygone

first_imgBALURGHAT: Gun firing in open air during Sandhipujo is a decade-long tradition of this Zamindar Barir Durga Puja — almost since the British era in India.The Puja, popularly known as Baidul Zamindar Barir Durga Puja, is held at the Chowdhury’s ancestral premises in Baidul.The puja was first started under the patronage of zamindar late Prasanna Lal Chowdhury in 1811. He had six sons and each family has one licenced gun as legal property, which is used in Durga Puja every year. Also Read – Rain batters Kolkata, cripples normal lifeThe Puja is organised rotationally by the family members of six sons once in every six years. Chowdhury family is celebrating the 108th year this Puja uninterruptedly, particularly even in the age of big-budget themed Pujas in South Dinajpur. This puja still remains a crowd-puller along with many revelers visting it for a taste of its unique heritage.Asking about the tradition of gun firing, Prasanna Lal’s grandson Mrityunjay Chowdhury who stays in Baidul, said: “The custom of gun firing started from early fifties as I learnt from my uncle late Kshitish Chandra Chowdhur. The area as I learnt from him was dominated by robbers and goons then. They had frequently targeted rich zamindars and landlords of the area. We were their soft target due to lack of proper security measures back then. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedAs a result, the rich people were forced to keep licenced firearms to keep goons and robbers at bay. Our forefathers had started the tradition of gun firing during Sandhipujo to send a stern message publicly that they can protect themselves from those anti-social elements. The person who fired the gun in the air during the Puja had to take blessings from Maa Durga, so that he can protect his family from unwanted incidents throughout the year. My father late Baidyanath Chowdhury, who was the youngest son of my grandfather told me that the six brothers had purchased one Belgium made double bore riffle along with four one-shutter India made riffle for self-defence.”Baidul is about 9.5 km from Balurghat and located on the banks of Atreyee River. According to the sources, there are about 21 family pujas across the district. “We are proud maintaining our ancestral tradition. The puja days are family reunion for us too as many of them are scattered in different parts of the country and foreign as well,” said Mainak Chowdhury, who is another successor and great-grandson of Prasanna Lal Chowdhury.last_img read more

The Ancient Greek Philosopher who Got Drunk and Laughed Himself to Death

first_imgEnjoying a laugh is thought to be as good as any tonic. Many’s the time a joke has saved someone from a bad day, or worse. Yet the expression “too much of a good thing” applies to laughter as with anything else. The Ancient Greek philosopher Chrysippus is a case in point. A towering figure in the field of Stoicism, he lived from c. 280 – 207 BC. Stoicism came from the teachings of Socrates and Heraclitus.It was described in the Encyclopaedia Britannica as, “one of the loftiest and most sublime philosophies in the record of Western civilization. In urging participation in human affairs, Stoics have always believed that the goal of all inquiry is to provide a mode of conduct characterized by tranquillity of mind and certainty of moral worth.”Roman copy of a Hellenistic bust of Chrysippus.In other words, Chrysippus valued the pure qualities of the mind over base pleasures, believing Man should instead use his brain in tandem with nature. How ironic then that his demise involved alcohol beverages and an innocent donkey.The death took place at the 143rd Olympiad where the drink was flowing and surely even the most stoic thinker was kicking off their sandals and having a good time. Two accounts exist of what transpired, with the first depicting Chrysippus as overcome by strong wine.“Now give the donkey a drink of pure wine to wash down the figs” cried Chrysippus and died in a fit of laughter.The second version is more colorful. Having watched a donkey chomping on figs, an idea occurred to Chrysippus that was far from philosophical. He boisterously suggested giving the creature some wine with its meal. It wasn’t comedy of the highest order but it worked for him. He laughed so much he expired.So a life distinguished by concepts such as propositional logic had ended in a decidedly un-Stoic fashion. Despite this, the death may have made sense to Chrysippus. He was a great believer in fate and the role it played in someone’s destiny.“The Death of Pietro Aretino,” by Anselm Feuerbach. Aretino was an Italian poet who reportedly died from laughter.A quote from De Fato by Cicero, meaning “On Fate,” sums up his thinking: “(But) every proposition is either true or false. Therefore, there is no motion without a cause. And if this is so, then all effects owe their existence to prior causes. And if this is so, all things happen by fate. It follows therefore that whatever happens, happens by fate.”Perhaps the wine and the donkey were there for a reason. Certainly, an unusual philosophical idea but the Ancient Greeks didn’t shy away from difficult questions.The myth of Pandora’s BoxAnother question that would occur to Chrysippus is ‘Can someone die laughing?’ While he died in the midst of mirth, was an underlying condition the real culprit? There are examples throughout history, both ancient and modern, of people keeling over during a fit of laughter.The answer could lie in the death of someone who was watching one of the world’s best-loved comedies. Gizmodo reports, “The most direct death by laughter reported is supposedly audiologist Ole Bentzen who, while watching A Fish Called Wanda, laughed uncontrollably. His heartbeat rose to ‘between 250-500 times per minute’ until he died.”“Gelastic syncope” (or laughter-induced fainting) is a rare but medically recognized condition.John Cleese’s expertly-crafted script aside, the experience put pressure on Ole Bentzen’s heart in the same way a long run or stressful situation might. The list of factors that contribute to heart failure are wide-ranging.An NBC news article from 2011 interviewed Professor of Neurology Dr. Martin Samuels, who provided some insight into possible death by laughter.A partial marble bust of Chrysippus – Roman copy of a Hellenistic original (Louvre Museum). Photo by Sting CC By SA 2.5“Extreme excitement, whether that be sadness or happiness activates the part of the brain that’s responsible for the flight or fight response to threats in the wild… This releases a natural chemical — adrenaline — which in large animals can be toxic to various organs, in particular, the heart.”The article goes on to say, “As a result, extremely strong emotional states — whether positive or negative — can be harmful to the heart, on rare occasions causing an abnormal rhythm which can be lethal.”Read another story from us: Only the Strong Survive: Did Vikings Abandon their Sick Children?So it seems the gift of laughter is actually not such a gift after all. It’s a puzzler that philosophers and comedians will no doubt be thinking about for years to come.Steve Palace is a writer, journalist and comedian from the UK.

Could not be more grateful, especially for their commitment to our veterans.”According to the BBC, “A highly trained dog, Sully can perform a number of commands, including opening doors and fetching items such as the phone when it rings. He will now work as a service dog, assisting with therapy for wounded soldiers.”The former president had been receiving treatment for a form of Parkinson’s disease and had been admitted to the hospital with a blood infection in April.The United States flag is lowered to half mast aboard USS George H.W.

Bush frequently used a wheelchair toward the end of his life, and Sully provided assistance with daily life.“Sully could open doors, pick up items and summon help,” The Associated Press reported.According to the Washington Post, “The display of instinctual, animalistic devotion captured the reaction to Bush’s death in a way that the words spilled all weekend over the Internet could not.

Last week, he was already preparing for Christmas.”That Sully will continue to serve veterans was important to the Bush family. George W.
