New York, October 28, 2016: Teachers underrating girls’ ability to solve problems in Mathematics will likely contribute to the widening of gender gap in the subject, finds a study.
According to the study, published in the journal AERA Open, beginning in early elementary school boys outperform girls in math — especially among the highest math achievers.

This leads to teachers giving lower ratings to girls’ math skills while both the genders have similar achievement and behaviour towards the subject.
“Despite changes in the educational landscape, our findings suggest that the gender gaps observed among children who entered kindergarten in 2010 are strikingly similar to what we saw in children who entered kindergarten in 1998,” said Joseph Robinson Cimpian, Associate Professor at the New York University.
Data showed that boys and girls began kindergarten with similar math proficiency, but disparities developed by Grade 3 with girls lagging behind. The gap was particularly large among the highest math achievers.

Research also revealed disparities in teacher perceptions of students, with teachers rating the math skill of girls lower than those of similarly behaving and performing boys.
Finally, the researchers examined gendered patterns of learning behaviours to try and explain why boys are more likely to score as high math achievers.
They found that girls’ more studious approaches to learning pay off by boosting them at the bottom of the achievement distribution, but do not help the persistent gap at the top as much.
The researchers explored the early development of gender gaps in math, including when disparities first appear, where in the distribution such gaps develop, and whether the gaps have changed over the years.

In addition to math achievement, they examined two potential contributors to gender gaps: students’ learning behaviours and teacher expectations.
Overall, the researchers found remarkable consistency across both cohorts. They observed that the gender gap at the top of the distribution (among the highest achievers in math) develops before students enter kindergarten, worsens through elementary school, and has not improved over the last decade.

Maryam Mirzakhani was the only woman to win mathematics equivalent of Nobel Prize
She died on Saturday as she was battling breast cancer
She was born in Iran and joined Stanford University in 2008 as a mathematics professor
STANFORD, CALIFORNIA, July 18, 2017:Maryam Mirzakhani, a Stanford University professor who was the first and only woman to win the prestigious Fields Medal in mathematics, has died. She was 40.
Mirzakhani, who battled breast cancer, died Saturday, the university announced. It did not indicate where she died.
In 2014, Mirzakhani was one of four winners of the Fields Medal, which is presented every four years and is considered the mathematics equivalent of the Nobel Prize. She was named for her work on complex geometry and dynamic systems.
“Mirzakhani specialized in theoretical mathematics that read like a foreign language by those outside of mathematics: moduli spaces, Teichmüller theory, hyperbolic geometry, Ergodic theory and symplectic geometry,” according to the Stanford press announcement. “Mastering these approaches allowed Mirzakhani to pursue her fascination for describing the geometric and dynamic complexities of curved surfaces — spheres, doughnut shapes and even amoebas — in as great detail as possible.”
The work had implications in fields ranging from cryptography to “the theoretical physics of how the universe came to exist,” the university said.
Mirzakhani was born in Tehran, Iran, and studied there and at Harvard University. She joined Stanford as a mathematics professor in 2008.
Iran’s President Hassan Rouhani issued a statement Saturday praising Mirzakhani. “The grievous passing of Maryam Mirzakhani, the eminent Iranian and world-renowned mathematician, is very much heart-rending,” Rouhani said in a message that was reported by the Tehran Times.
Iran’s foreign minister, Mohammad Javad Zarif, said her death pained all Iranians, the Tehran Times reported.
“The news of young Iranian genius and math professor Maryam Mirzakhani’s passing has brought a deep pang of sorrow to me and all Iranians who are proud of their eminent and distinguished scientists,” Zarif posted in Farsi on his Instagram account. “I do offer my heartfelt condolences upon the passing of this lady scientist to all Iranians worldwide, her grieving family and the scientific community.”
Mirzakhani originally dreamed of becoming a writer but then shifted to mathematics.
When she was working, Mirzakhani would doodle on sheets of paper and scribble formulas on the edges of her drawings, leading her daughter to describe the work as painting, according to the Stanford statement.
Mirzakhani once described her work as “like being lost in a jungle and trying to use all the knowledge that you can gather to come up with some new tricks, and with some luck, you might find a way out.”
Stanford President Marc Tessier-Lavigne called Mirzakhani a brilliant theorist who made enduring contributions and inspired thousands of women to pursue math and science.
Mirzakhani is survived by her husband, Jan Vondrák, and daughter, Anahita. (VOA)
New approach to this study made by Eunsoo Lee who is a PhD student in Classics at Stanford University
Lee was confused by the blind spot in the study of Elements which changed drastically over time after multiple copies and translations
His professor considered his project as unique and groundbreaking in the field of classics
June 26, 2017: Geometry diagrams and patterns have been with us for a very long time. Whether we liked it or not, we all had to make diagrams and read geometry books when we were in school. Now, researchers are trying to understand the geometric patterns through examinations of texts and writing which is also known as philology.
There is a new approach to this study made by Eunsoo Lee who is a PhD student in Classics at Stanford University by tracing the changes and variations in diagrams over the course of human history.
Lee examined the changes in diagrams used in a collection of 13 books on mathematical and geometry concepts called Elements, written by Euclid, an ancient Greek mathematician.
Lee first got to know about Elements during his mathematics undergraduate degree at Seoul National University. He said, “I was fascinated by its simple logic and structure.”
Reviel Netz, professor of classics said, “Until recently, no one has really examined the visual side of ancient science, you would try to recover the words that people said but you didn’t try to recover the visual impact, the images.”
Lee was confused by the blind spot in the study of Elements which changed drastically over time after multiple copies and translations. This became the basis of Lee’s project, which his professor considered as unique and groundbreaking in the field of classics.
Netz Said, “We’ve come to realise just how central images are to scientific thinking. You do one kind of science when you assume that diagrams are precise pictures, and you do a different kind of science when diagrams are assumed to be just rough sketches.”

Depending on the location, the proliferation of IS has drawn varied resistance from the Afghan military, U.S. air support and ground troops, local militias, Taliban forces and other militant groups
Afghan army planes on Wednesday night accidentally air dropped vital supplies of food and water to IS militants in the Darzab district of northern Jouzjan province instead of to their own besieged troops
In the Tora Bora area, where IS has made a strong stand in recent days, local villagers and militias joined with Taliban to rout IS
June 25, 2017: The Islamic State group is rapidly expanding in parts of Afghanistan, advancing militarily into areas where it once had a weak presence and strengthening its forces in core regions, according to Afghan and U.S. officials.
Depending on the location, the proliferation of IS has drawn varied resistance from the Afghan military, U.S. air support and ground troops, local militias, Taliban forces and other militant groups.
Attacking IS has become such a priority in the country, that disparate forces sometimes join together in the ad-hoc fight, with Afghan and U.S. forces finding themselves inadvertently supporting the enemy Taliban in battling IS.
Confusion leads to mistakes
All too often, officials say, mistakes are made due to confusion on the ground.
Afghan army planes on Wednesday night accidentally air dropped vital supplies of food and water to IS militants in the Darzab district of northern Jouzjan province instead of to their own besieged troops, provincial police chief, Rahmatullah Turkistani told VOA. The supplies were meant to help Afghan forces that are countering twin attacks by IS and Taliban militants but were used instead by IS.
“It’s not getting better in Afghanistan in terms of IS,” U.S. Chief Pentagon Spokeswoman Dana White told VOA this week. “We have a problem, and we have to defeat them and we have to be focused on that problem.”
Reinforcements for the IS cause reportedly are streaming into isolated areas of the country from far and wide. There are reports of fighters from varied nationalities joining the ranks, including militants from Pakistan, India, Iran, Iraq, Syria, Russia and Central Asian neighbors.
Still, the Islamic State-Khorasan (ISK) as IS is known in Afghanistan remains a fragmented group composed of differing regional forces with different agendas in different parts of the country.
“IS-K is still conducting low-level recruiting and distribution of propaganda in various provinces across Afghanistan, but it does not have the ability or authority to conduct multiple operations across the country,” a recent Pentagon report said. But where it operates, IS is inflicting chaos and casualties and causing confusing scenarios for disparate opponents.
In the Tora Bora area, where IS has made a strong stand in recent days, local villagers and militias joined with Taliban to rout IS. IS regained ground after a few days, leading to U.S. military air attacks on IS positions in conjunction with Afghan intelligence instructions and army operations.
IS fighters reportedly have fled from mountain caves of Tora Bora, where al-Qaida’s leader Osama bin Laden hid from U.S. attack in 2001.
IS fighters were also reportedly advancing in neighboring Khogyani district, displacing hundreds of families, according to district officials. It is one of several areas in Nangarhar province, near the Pakistani border, where IS has been active for over two years.
Fierce clashes in the Chaparhar district of Nangarhar last month left 21 Taliban fighters and seven IS militants dead, according to a provincial spokesman. At least three civilians who were caught in the crossfire were killed and five others wounded.
“IS has overpowered Taliban in some parts of Nangarhar because the Taliban dispatched its elite commando force called Sara Qeta (Red Brigade) to other parts of the country, including some northern provinces to contain the growing influence of IS there,” Wahid Muzhda, a Taliban expert in Kabul, told VOA.
IS has also expanded in neighboring Kunar province, where, according to provincial police chief, it has a presence in at least eight districts and runs a training base, where foreign members of IS, train new recruits.
Hundreds of miles from Nangarhar, IS is attempting to establish a persistent presence in several northern provinces where it has found a fertile ground for attracting militants and recruiting unemployed youths, mostly between the age of 13 and 20.
IS has been able to draw its members from the Pakistani Taliban fighters, former Afghan Taliban, and other militants who “believe that associating with or pledging allegiance” to IS will further their interests, according to the Pentagon report.
Hundreds of militants have joined IS ranks in northern Jouzjan and Sar-e-Pul province where local militant commanders lead IS-affiliate groups in several districts.
Qari Hekmat, an ethnic Uzbek and former Taliban militant who joined IS a year ago, claims to have up to 500 members, including around 50 Uzbek nationals who are affiliated with the Islamic Movement of Uzbekistan (IMU) — previously associated with al-Qaida and Taliban in Afghanistan.
IS and Taliban are reportedly fighting over the control of Darzab district in Jouzjan which they stormed this week from two different directions and besieged scores of government forces. The Taliban has reportedly captured the center of the district while IS militants control the city outskirts.
Afghanistan faces a continuing threat from as many as 20 insurgent and terrorist networks present or operating in the Afghanistan-Pakistan region, including IS, the Pentagon said.
“In areas where the government has limited influence and control, IS attempts to emerge and expand there,” Ateequllah Amarkhail, an analysts and former Army general in Kabul told VOA.
IS has also claimed responsibility for several recent attacks in urban areas, however, with a hit-and-hide strategy that is proving effective. And it is engaging too in more skirmishes with U.S. forces that initially were sent to the country to help Afghan forces halt the spread of Taliban.
Three American service members based in eastern Afghanistan were killed in April during operations targeting IS militants, according to the Pentagon.
“ISIS-K remains a threat to Afghan and regional security, a threat to U.S. and coalition forces, and it retains the ability to conduct high-profile attacks in urban centers,” the Pentagon said. (VOA)
