【推荐1】James Gross, a psychology professor at Stanford University, has a 13-year-old daughter who loves math and science. “It hasn’t occurred to her yet that’s unusual,” he says. “But I know in the next couple of years, it will.”

She’s already being pulled out of class to do advanced things with a couple of other kids, who are guys. And as someone who studies human emotion for a procession, Gross says, “I know as time goes on, she will feel increasingly lonely as a girl who’s interested in math and science, and be at risk of narrowing her choices in life before finding out how far she could have gone.’’

Gross’ concern clearly shows what has been a touchy subject in the world of science for a long time: Why are there still so few women in science, and how might that affect what we learn from research?

Women now make up half the national workforce, earn more college and graduate degrees than men, and by some estimates represent the largest single economic force in the world. Yet the gender gap in science persists, to a greater degree than in other professions, particularly in high-end, math-intensive fields such as computer science and engineering.

According to US Census Bureau statistics, women in fields commonly referred to as STEM (science, technology, engineering, mathematics) made up 7 percent of that workforce in 1970, a figure that had jumped to 23 percent by 1990. But the rise essentially stopped there. Two decades later, in 2011, women made up 26 percent of the science workforce.

【推荐2】Examining the classroom practices of National Teacher of the Year winners and finalists, the study, by Michigan State University scholars, suggests successful educators aren’t afraid to push the boundaries by adding real world, cross-disciplinary（跨学科的）themes into their lessons.

The study, published online in the journal Teachers College Record, is one of the first in depth investigations of how teachers use creativity in the classroom.

“The best teachers are taking their own creative interests – from rap music to cooking to kickboxing – and are finding ways to include these into the curriculum,” said Danah Henriksen, lead author of the study. “They’re bringing together different subject matters and finding areas of connections so students can learn both in interesting ways.”

America’s test-driven educational policy, Henriksen argues, has impeded creativity in teaching and learning. Many teachers today struggle to balance high-stakes（高风险）testing and responsibility to act flexibly and independently in their classrooms.

“I think that there’s a lot of fear.” one of the award-winning teachers says in the study, “And when teachers are teaching in fear, they take few risks, for they have to consider exams and academic performance.”

The findings have major implications（含意）for teaching and learning. Teachers’ unique creative interests should be brought into classroom lessons, along with arts and music across varied academic content. Teacher education programs and professiona1 development courses should include a focus on real world. Administrators and policymakers should support opportunities for teachers to take creative and intellectua1 risks in their work.

“If we want teachers to be creative, we need to provide them with opportunities to bring those outside interests into their professional life,” said Mishra, study co-author and MSU professor of educational psychology and educational technology. “The point is to find what works for you, what is your passion and interest and how can you put that into what your students are learning. Finally, we teach who we are. That’s the most powerful finding.”

【推荐1】Seated at the grand piano in MIT’s Killian Hall last fall, first-year student Jacqueline Wang played one piece of Mozart’s music. When she’d finished, Mi-Eun Kim, a pianist and lecturer at MIT, asked her to move to the back of the hall. Kim tapped at an iPad. Suddenly, the music Wang had just played poured forth again from the piano - its keys sinking and rising just as they had with Wang’s fingers on them. Wang stood with a confused expression, taking in a repeat of her own performance.

This unusual lesson took place during a three-week residency (驻留期) of the Steinway Spirio|r, a piano that obtains the data of live performances and offers students new possibilities for studying and experimenting with music.

Wang was one of several participants to have the experience of hearing herself play while watching the data of her performance move up and down across a screen: color-coded rectangles (矩形) indicating the speed and duration of each note, and a moving line charting her use of the damper pedal (阻尼踏板). Wang could even edit her own performance when Kim suggested her rhythmic use of the pedal might be unnecessary. Using the iPad interface to erase the pedaling entirely, they listened to the playback again, the notes gaining new clarity,

For Wang, the session introduced an element she’d never experienced since beginning her piano studies. The visual display of how long each key was played and with what speed gave her a more precise demonstration of the ideas of voicing and evenness.

Playing the piano is one of the most complex activities that humans do with their hands. Some people might think the new technology will replace the pianist. In Kim’s view, that human complexity is complemented by this kind of technical possibility. But it doesn’t mean all of the things that go into learning music will be abandoned. It’s going to be an invaluable third partner: the student, the teacher, and the Spirio | r. It’s going to play a necessary role in lots of musical efforts.

【推荐2】Languages like Italian or Finnish can be spelled more easily because each letter of the alphabet matches to one sound. Students studying these languages can have 90 percent reading accuracy after the first year. However, students even after years of learning English are still far below Italian or Finnish students in reading accuracy.

English started as a Germanic language. It is most closely connected to German and Dutch, especially in grammar and basic vocabulary. During the Norman invasion in the 12th century, Old English was spoken but French was used in government and legal documents. And Latin was used in religious and educational activities. As a result, more French and Latin words entered the English language. The printing press invented in the late 1400s helped to establish English spelling. The English of today is how the language was written at the time. However, the spoken language started to change in the 1500s with the pronunciation of all long vowels (元音). For example, “bite” was pronounced closer to “beet” in the 1400s, before changing through the years to its current sound. The effect was that the English language had old spellings, but new sounds.

【推荐3】New research links outdoor air pollution — even at levels considered safe — to an increased risk of diabetes (糖尿病) globally, according to a study from the VA St. Louis Health Care System. The findings raise the possibility that reducing pollution may lead to a drop in diabetes cases in heavily polluted countries such as India and less polluted ones such as the United States.

Diabetes is one of the fastest growing diseases, affecting more than 500 million people worldwide. The main drivers of diabetes include eating an unhealthy diet, having a sedentary lifestyle and obesity, but the new research indicates the extent to which outdoor air pollution plays a role.

“Our research shows a significant link between air pollution and diabetes globally,” said Ziyad Al-Aly, MD, the study’s senior author and an assistant professor of medicine at the University of Washington. “We found an increased risk, even at low levels of air pollution currently considered safe by the US Environmental Protection Agency (EPA) and the World Health Organization (WHO). This is important because many industry lobbying (游说) groups argue that current levels are too stringent and should be relaxed. Evidence shows that current levels are still not sufficiently safe and need to be tightened.”

While growing evidence has suggested a link between air pollution and diabetes, researchers have not attempted to quantify that burden until now. “Over the past two decades, there have been bits of research about diabetes and pollution,” said Al-Aly. “We wanted to thread together the pieces for a broader, more solid understanding.”

The researchers also found that the overall risk of pollution-related diabetes tilted (倾斜) more toward lower-income countries such as India that lack the resources for environmental mitigation systems and clean-air policies. For instance, poverty-stricken countries facing a higher diabetes-pollution risk include Afghanistan, Papua New Guinea and Guyana, while richer countries such as France, Finland and Iceland experience a lower risk. The US experiences a medium risk of pollution-related diabetes.
