Noise and Ecosystems

Research suggests noise can rattle an ecosystem. Birds, for example, rely on their voices to woo mates, size up rivals, scrounge for dinner. Horn blasts and engine revs can scramble auditory cues. Birds try singing louder, singing at a higher frequency, singing at night. Some abandon their nests altogether. This can trigger an ecological cascade, one that extends even to vegetation; noise can scare away some birds that would normally scatter seeds.

I read a lot of random stuff over the course of a week, and I tweet out many of them (follow me @mandercorn), but I also know that roundups of links, ala Chalkbeat NY, Vox, Eduwonk, Marginal Revolution, and many others, are a really useful way to sharing items that are interesting.

I’m going to begin posting a weekly roundup of items that bear a connection to the themes and ideas that we explore on Schools & Ecosystems.

Please let me know if there’s a format I should consider that will make these more easily digestible and useful to you.

Schools that teach in two languages foster integration — so how come so many families can’t find programs?

There has been a long overdue discussion of integration and increasing diversity in our public schools. While those discussions typically refer to racial and socioeconomic diversity, and the subsequent resistance from well-off white parents, Catherine Brown and Conor Williams are forwarding a refreshing vision for increasing diversity: expanding Dual Language Immersion programs.

While no integration effort is ever simple —especially one that requires schools to implement a new instructional model — today’s conditions are encouraging. Schools have increasing numbers of linguistically diverse students, and greater flexibility for deciding how to meet their needs. Furthermore, families of varied backgrounds increasingly expect schools to offer unique academic themes that help students succeed. Dual immersion programs recognize and celebrate their diverse backgrounds, not as a side benefit, but as a core element of the model’s effectiveness. That’s an extraordinary opportunity for policymakers — and well worth their attention.

Hospitals Realize Their Own Noise Is a Health Issue All By Itself

Quartz reports on a study which found that ambient noise in hospitals is LOUD, which is unsurprising to anyone who has stayed in a hospital.

Hospital stays can be an ordeal all by themselves beyond the condition you’re there being treated for. As medicine becomes more holistic in its perspective, it only makes sense that hospitals are realizing what an important role sound can play in effective healthcare.

On Average

A podcast episode from 99% Invisible describes the tremendous influence that the science of averages, promulgated by Belgian astronomer and mathematician Adolphe Quetelet, has had on design.

Did you know that clothing sizes of Large, Medium, and Small were first created by the mass production for soldier uniforms required by the Civil War? Lincoln drew from the science of averages.

There’s a common discourse in the education world: we standardize tests and our education systems, but children aren’t standardized. It might sound trite, but it’s scientifically accurate, according to research by Gilbert S. Daniels. He discovered that there was a discrepancy between the averages of all soldier measurements and the actual individual sizes of each soldier. In other words, very few individual soldiers actually conformed to the average.

This problem manifested in the design of cockpits, which were based on average measurements of soldiers in the 1920s. By WWII, those averages no longer applied, and resulted not only in the exclusion and subsequent shortage of many pilots during a time of high need, but even many avoidable deaths.

It was again our military which then pioneered the concept of adjustment in its design to meet individual needs. That’s why we can adjust our car seats now.

Whether it’s the equipment, or the whole work environment, design must accommodate more people who are outside the average … because in reality no one is actually average.

Trudging the fields at Gettysburg to teach leadership in hospitals

Speaking of hospitals and the Civil War . . . Stat reports on a leadership program for hospital staff which brings them to the battlefield of Gettysburg and prompts them to consider the decision-making challenges that people working within large organizations can make while under stress.

“Communication can break down at every single level,” said David Ottati, chief executive of Florida Hospital Waterman. “As leaders, we need to make sure we understand the objectives and each others’ personalities and motivations.”

In the Age of De Blasio, A Bloomberg Era Small School Reunion

Andrea Gabor writes a thoughtful piece on an innovative small school, Global Technology Preparatory, that was created as part of Bloomberg/Klein’s “iZone” initiative. By explaining what makes this school a success, and examining how that success has been hampered by politics and bureaucracy, Gabor brings a critical lens to the new administration.

One of the buried ledes in this story is that an educator, David Baiz, had been rated Unsatisfactory in his first school in the South Bronx, but after moving to Global Tech, he became a “nationally recognized math teacher.”

New York City educators loved to hate the Bloomberg/Klein administration, with its penchant for serial reorganizations and its army of MBAs. At the same time, some of the city’s best principals conceded that the businessman-mayor’s school administration had made their lives easier. For principals who survived the New York City iZone’s many incarnations, or who had inherited the small-school mantel from Meier and Alvarado, the Bloomberg years were an opportunity to experiment with some relief from bureaucratic control.

When our dream school had no space for my son, I panicked. Then I confronted prejudice I didn’t know I had

A mother and educator describes how the experience of choosing a school for her son confronted her with her own prejudice and that of others.

The more I dug into my soul, the more I come back to the idea that choosing a school is essentially about choosing the class you want to belong to and not about education at all. The truth that nobody wants to talk about is they want their white child to go to a white school. They want to go to a school where everyone eats Pirate Booty instead of Cheetos, where parents send their kids to New York Kids Club instead of Chuck E. Cheese’s.

Noise Affects Learning

Noise has also been shown to affect learning ability. In 1975 Bronzaft collaborated on a study of children in a school near an elevated train track that showed how exposure to noise can affect children’s reading ability. Half of the students in the study were in classrooms facing the train track and the other half were in classrooms in the school’s quieter back section. The findings, published in the December 1975 issue of Environment and Behavior, were that students on the quieter side performed better on reading tests, and by sixth grade they were a full grade point ahead of the students in the noisier classrooms.

Bronzaft and the school principal persuaded the school board to have acoustical tile installed in the classrooms adjacent to the tracks. The Transit Authority also treated the tracks near the school to make them less noisy. A follow-up study published in the September 1981 issue of the Journal of Environmental Psychology found that children’s reading scores improved after these interventions were put in place. “After we did the study, more than twenty-five other studies were done examining the effect of noise on children’s learning ability,” Bronzaft says. “They have all found the same thing to be true: noise can affect children’s learning.”
