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

Apply it on your skin and let it dry. Then rub it off and wash. Do this once or twice a week. Another option is to create a natural scrub. For softer arm skin, combine sugar crystals with rose oil.

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.

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
