AP Exams Are Still On Amid Coronavirus, Raising Questions About Fairness

; Credit: /Jackie Ferrentino for NPR

Carrie Jung | NPR

A lot is at stake for students taking Advanced Placement exams, even in normal times. If you score high enough, you can earn college credit. It's also a big factor in college applications. But for some students, the idea of studying right now feels impossible.

"I'm constantly thinking about making sure my family doesn't get sick and I don't get sick," says Elise, a high school junior outside Boston. (We're not using her full name because she's worried about hurting her college applications.)

Concerns about the coronavirus have put most standardized tests, such as the SAT and ACT, on hold this spring. But AP exams are going forward with a new online format — and that's raising questions about fairness.

Elise, 17, says she spent months preparing for what is typically a three-hour, multiple-choice and essay-based exam; she was blindsided when she learned it will now be an online, 45-minute, open-response test.

"I have no idea what I'm going to get when I open that test," she says.

Elise was hoping the College Board, which administers AP exams, would cancel this year's exams, as it did the spring SATs. But since the tests are being offered, she says she feels she has to take them. She worries it would look bad on her college applications if she opted out.

For other students, just the idea of taking the exam at home is causing anxiety. Kayleen Guzman, 17, from Boston says it's hard to find peace and quiet in her house right now.

"Currently, it's me, my mom, my dog, my sister and my stepdad," she explains. "Sometimes I feel like it's too much chaos."

But Guzman is glad she still has the opportunity to take the AP exams at all this year. She says she worked hard in her two AP classes and she wants the chance to earn college credit.

However, it's still unclear how much credit colleges will give students for this year's exams.

"None of us would say that we are confident that a 3 or 4 or 5 on the AP exam this year means the exact same thing as a 3, 4 and 5 on the exam last year," says Harvard University's Andrew Ho, who studies the reliability of educational tests.

Ho says that because of the new format, this year's AP exams won't be measuring the same thing as previous years' exams. For one, the new tests will cover less material. And changing where kids take it — from a proctored classroom to their laptops at home — is a big deal. But Ho adds, "Just because it's not completely comparable doesn't mean the College Board and colleges, through their own policies, couldn't adjust."

Some colleges are already adjusting. The University of California system has come out explicitly to say it won't change the way it credits AP scores. Other colleges that didn't want to go on the record say they are planning to change their policies, but the details weren't ready to share just yet.

In a statement, College Board spokesperson Jerome White said the organization decided to move forward with AP testing to give motivated students the opportunity to earn college credit. He added that the organization is making "a significant financial investment" to make the exams available online, from cheating prevention software to helping students who may not have an Internet connection or access to a computer.

Still, some educators worry that those efforts won't be enough.

"This situation has created a lot of distraction," says Savannah Lodge-Scharff, an AP Physics teacher for Boston Public Schools. She argues that without in-person classes, many students won't be able to engage with the material in the same way. On top of that, financial stress means many of her students are juggling additional responsibilities, like taking care of siblings.

"I have some of my students who are working 40, 50, 60 hours a week at the grocery store right now in the fear their parents are going to be laid off," she explains.

And then there's the question of geographic equity. This year's exams will be administered at the same time worldwide, meaning students in Hong Kong will be up at midnight to take it.

FilmWeek®

Brad Bird has made a name for himself as the director of new age, animated classics, like “The Iron Giant” and “The Incredibles”. Now he’s teaming up with Turner Classic Movies to share his picks for classic movie watching that will keep you busy and entertained while you’re stuck at home.

Bird has curated a list of his favorite films which will air on this season’s “The Essentials” with TCM Primetime host Ben Mankiewicz. Every Saturday from May up to January of next year, TCM will air one of twenty movies chosen by Bird. His list includes big-name classics that any movie buff will recognize, like “Casablanca” and “Dr. Strangelove”. But Bird throws in a few surprises, one being that there are no animated films on his list. Another surprising thing viewers will notice is that about a third of the films included are musicals, like “Singin’ In The Rain” and “Guys And Dolls”. With TCM’s seemingly infinite library of movie classics to choose from, Bird says narrowing it down to only twenty favorites was a challenge. According to Bird, his list comprises movies that are not only entertaining but “transcend time” and “speak in a language that is still in many ways current”.

“The Essentials” was filmed in early December, but Bird’s list is coming out during a time when movie-going is looking very different these days. The virus has put the entire film industry on pause, with studios halting production and theaters closing their doors indefinitely. In lieu of new movie releases and regular theater-going, many are taking the opportunity to revisit the classics and Bird’s list provides a starting guide for which ones should be on your watch-list.

Today on FilmWeek, Brad Bird joins us to talk about his favorite movies, what projects he has lined up, and his thoughts on how the film industry is adjusting to and getting through the pandemic.

TCM’s “The Essentials” will air on Saturdays at 8 p.m. beginning May 2. For the full list and schedule of films, click here.

Guest:

Brad Bird, animator, director and screenwriter whose directing credits include Pixar’s “Ratatouille” and “The Incredibles” films and Disney’s “The Iron Giant”; he tweets at @BradBirdA113

Assessing cumulative impacts on seabed ecosystems

Understanding the impacts of human activities on Marine and Coastal is important to ensure their sustainability. New research has indicated that seafloor ecosystems are less likely to recover from fishing if they are in rocky or reef habitats and if dredging and bottom trawling equipment is used for shellfish and various fish species. When fishing is combined with the extraction of aggregate for mineral resources, the impacts are even more damaging.

Antarctica needs global and local responses to protect ecosystems

A new study has investigated the impacts of human activity on Antarctic Marine and Coastal. Alongside local effects of fishing, pollution and invasive alien species, global climate change is causing sea temperature rises and ocean acidification. Action is therefore needed at all levels to address these impacts.

One-Way Sidewalks And Parking Lot Dining Rooms: Is This The Future?

Small businesses are essential to cities and towns across the country. They create jobs, they create a sense of place — think of New York City without bodegas, Portland, Ore., without bike shops, or your town without its dance studio or hardware store — but they also create sales, income, and property tax revenues.

"[It's] super important that we make it very easy for people to keep their purchases local," said Karina Ricks, director of the Department of Mobility and Infrastructure in Pittsburgh, Pa.

Cities like Pittsburgh must make it possible to return to the streets and shop without losing the safety of physical distancing, said Ricks. If only so many people are allowed into a store at one time, how can others line up outside? If restaurants operate at 25 percent capacity, where will expectant diners wait?

"It's going to require us to reimagine our streets," she said. "How much of our streets can we turn over?"

Many cities have already removed cars from streets to allow more people to walk and bike. They'll need even more space if people are allowed to go to shops and restaurants again, said Brent Toderian, the former chief planner for Vancouver, Canada who now leads his own company, TODERIAN UrbanWORKS.

"All of it requires more space between buildings, more life between buildings," he said. "If we try to do all that without inconveniencing the cars, we will fail."

In Tampa, Fla., officials will allow restaurants to add tables to streets in front of their establishments. In an Atlanta, Ga. suburb parking lots are the new dining room. Ricks wonders if one-way sidewalks could limit people's exposures to one another the way one-way aisles do in grocery stores. She said some Pittsburgh streets may open to cars only at certain times of the day, or speeds could be dramatically reduced. That way, street parking could be dedicated for walking, biking, or cafe tables while an adjacent travel lane for cars remains.

"I don't have the answers right now, but it's something that we're actively looking at," she said, citing a new city task force that will investigate the issue.

Public space always influences health outcomes and can produce health risks, said Keshia Pollack Porter, a professor at John Hopkins University's Bloomberg School of Public Health. Whatever "normal" cities think they're returning to, this is a chance to evaluate how the public realm worked before, she said.

"We know that there are significant inequities," she said, pointing to pedestrian and cyclist fatalities that continue to rise, and communities that have lacked access to safe streets for decades.

In a post-pandemic world, with even fewer dollars for infrastructure and transportation, officials must be more careful than ever, said Toderian.

"Where we put our money based on our assumed narratives around what people will want to do — drive more, take public transit less — will create self-fulfilling prophecies," he said, and could exacerbate that other existential threat, climate change.

More Census Workers To Return To Rural Areas In 9 States To Leave Forms

The Census Bureau says it will continue its relaunch of limited field operations for the 2020 census next week in some rural communities in nine states.; Credit: Matt Rourke/AP

Hansi Lo Wang | NPR

The Census Bureau says it is continuing the gradual relaunch of limited field operations for the 2020 census next week in nine states where the coronavirus pandemic forced the hand-delivery of paper forms in rural areas to be suspended in mid-March.

On May 13, some local census offices in Florida, Georgia, Kansas, Kentucky, Missouri, North Carolina, Oregon, Pennsylvania and Washington are scheduled to restart that fieldwork, according to an updated schedule the bureau published on its website Friday.

All workers are expected to be trained in CDC guidance in preventing the spread of COVID-19, and besides a new reusable face mask for every 10 days worked and a pair of gloves for each work day, the bureau has ordered 2 ounces of hand sanitizer for each census worker conducting field operations, the bureau tells NPR in an email.

The announcement means more households that receive their mail at post office boxes or drop points are expected to find paper questionnaires left outside their front doors soon. In areas where access to the online census form at my2020census.gov can be spotty, paper forms help ensure that all homes can participate in the once-a-decade head count of every U.S. resident.

The results are used to determine how many congressional seats and Electoral College votes each state gets through 2030. They also guide the redrawing of voting districts and the distribution of an estimated $1.5 trillion a year in federal funding for schools, roads and other public services in local communities.

The Census Bureau also announced on Friday that fingerprinting for newly hired census workers will pick up again next week in and around Philadelphia, Seattle, Portland, Ore., and Pittsburgh. With responses from close to 86 million households bringing the national self-response rate to just over 58% as of Thursday, the federal government is relying on staffing up with enough door knockers to complete the count. They're currently scheduled to make in-person visits to unresponsive homes starting in August.

Last month, Census Bureau officials asked Congress to consider pushing back the legal deadlines for delivering census data used to reapportion House seats and reshape voting maps by four months because of the delays brought on by the coronavirus.

In a letter to U.S. Senate leaders released on Friday, more than a dozen Democratic senators led by Brian Schatz of Hawaii are calling for the next COVID-19 relief package to include more funding and requirements for the Census Bureau "to keep both field workers and the public safe while conducting this constitutionally required enumeration."

Small firms and nonprofits like KPCC struggle with technology's diversity problem

Brian Watt

KPCC recently reported on the tech world’s diversity problem. Technology firms face challenges in hiring diverse staffs of its coders, web developers and software engineers.

It’s also a challenge at nonprofits such as Southern California Public Radio,  parent of 89.3 KPCC, which has always sought to build a staff that reflects the region it serves. The section of that staff that develops the KPCC app and makes its website run is all white and mostly male.

But a small talent pool means the diversity challenge is even greater for nonprofits and even smaller tech firms.

“The first problem is that all of the people working for me are male,” says Alex Schaffert, the one female on KPCC’s tech team.  “I’m kind of focusing on maybe getting another girl into the mix.”

Schaffert can use the term “girl” because she happens to be the leader of the tech team:  KPCC’s Managing Director of Digital Strategy and Innovation. 

Why diversity is important

Schaffert recently launched the topic of diversity – or lack thereof – at a weekly meeting of her team. She expected a “stilted and awkward” discussion from the five white men on her team, but a few of them didn’t hold back.  

“Not having diversity represented on the team leaves us more susceptible to circular thinking and everyone sort of verifying each other's assumptions,” said Joel Withrow,  who was serving at the time as KPCC’s Product Manager. “It impacts the work. It limits what you’re able to build.”

Sean Dillingham, KPCC’s Design and Development Manager, said living in a diverse community is what attracted him to Los Angeles, and he wants diversity in his immediate work team, too.

“When I look at other tech companies, I will often go to their ‘about us’ page, where they’ll have a page of photos of everyone, and I am immediately turned off when I just see just a sea of white dudes, or even just a sea of dudes,” Dillingham said.

Big competition, small talent pool

Dillingham and Schaffert are currently recruiting heavily to fill two tech-savvy positions. When a reporter or editor job opens up at KPCC, Schaffert says close to 100 resumes come in.

"But if you post a programmer job, and you get three or four resumes, you may not get lucky among those resumes," she says. "There may not be a woman in there. There may not be a person of color in there."

In other words, the talent pool is already small, and the diversity challenge makes it even smaller. KPCC is competing for talent with Google and Yahoo and all the start-ups on L.A.’s Silicon Beach. 

Schaffert’s being proactive, mining LinkedIn and staging networking events to attract potential candidates. She’s also trying to make sure KPCC’s job descriptions don’t sound like some she's seen in the tech world.

"If you read between the lines, they’re really looking for someone who is male and is somewhere between 25-30 years old and likes foosball tables and free energy drinks in the refrigerator," Schaffert says. “So you read between lines, and you know that they’re not talking about me, a mother of two kids who also has a demanding career. They're talking about someone different.”

Pay vs. passion

Schaffert's challenges and approaches to dealing with them are similar to those of Mary Ann de Lares Norris, the Chief Operating Officer at Oblong Industries. Based in downtown Los Angeles and founded in 2006, the company designs operating platforms for businesses that allow teams to collaborate in real time on digital parts of a project.

“I think technology and diversity is tough,” Norris told KPCC.  She’s proud her company’s management ranks are diverse, but says only 12 percent of its engineers are female. “Pretty standard in the tech industry, but it’s not great,” Norris says. “We really strive to increase that number, and all of the other companies are also, and it's really hard.”

Like Schaffert at KPCC, Norris works hard fine-tuning job descriptions and communicating that her company values diversity and work-life balance. But sometimes, it just boils down to money.

"We have to put out offers that have competitive salaries,” Norris says, adding that she can’t compete with the major tech firms. "The Googles and the Facebooks of the world can always pay more than we can. So we attract people who are passionate about coming to work for Oblong.  And, of course, we also offer stock options."

KPCC doesn’t have the  stock options, but we’ve got plenty of passion. Could that be the secret recruiting weapon for both small tech companies and nonprofits?  

LinkedIn recently surveyed engineers about what they look for in an employer. Good pay and work-life balance were the two top draws. Slightly more women prioritized work-life balance and slightly more men chose the big bucks. 

Clinical Entrepreneurship professor Adlai Wertman says that, historically, nonprofits and small businesses actually had the upper hand over big companies in recruiting minorities and women.

"There’s a feeling that they’re safer, more caring environments, less killer environments, and we know that corporate America has been the bastion of white males," said Wertman. 

But Wertman says that advantage disappears in the tech world because of the "supply-and-demand" problem with talent. When big firms decide to focus on diversity – as some have recently — they have plenty of resources.

"They’re always going to be able to pay more, and in truth they’re getting access to students coming out of these schools in ways that we as nonprofits and small companies never will," said Wertman. 

Wertman worked 18 years as an investment banker on Wall Street, then left to head a nonprofit on L.A.’s skid row. Now he heads the Brittingham Social Enterprise Lab Enterprise Lab at USC’s Marshall School of Business. He believes that, early on, the big companies have the best shot attracting diverse tech talent. But in the long run, much of that talent will turn back to smaller firms and nonprofits.

"I think ultimately people vote with where they’re most comfortable, where 'my values align with my employer's values, and if I don’t feel those values align, then I’m going to leave,'" Wertman said. "Ultimately, I think, for a lot of women and minorities, there’s a lot of value alignment within communities that are doing good in the world."

Microplastic particles in North Sea could harm marine organisms and enter human food chain

Researchers have discovered high levels of plastic particles and fibres, as well as black carbon (BC), which is formed by the incomplete burning of fossil fuels, in the waters of the Jade Bay, an inshore basin off the coast of Germany in the Southern North Sea. The concentration of suspended particles are of concern because they have the potential to be ingested by fish and other marine life, and enter the food chain.

Marine litter in deep sea ecosystems of the Mediterranean

Marine litter is a major issue in deep sea ecosystems in the Mediterranean Sea, new research confirms.

Global groundwater pumping lowers the flow of water bodies and threatens freshwater and estuarine ecosystems

Groundwater is the earth’s largest freshwater resource and is vital for irrigation and global food production. In dry periods farmers pump groundwater to water crops, this is already happening at an unsustainable level in many places — exceeding the rate at which rain and rivers can refill the groundwater stores. This study seeks to identify where groundwater pumping is affecting stream flows and estimates where and when environmentally critical stream flows — required to maintain healthy ecosystems — can no longer be sustained.

Routine monitoring of Mediterranean boats and marinas could help protect ecosystems from invasive alien species

A survey of over 600 private boats docked in marinas throughout the Mediterranean showed that 71% are carrying non-indigenous species. In certain cases, non-indigenous species can become ‘invasive’ and have enormous and long-lasting impacts on ecosystems. The findings suggest that a common monitoring strategy may be necessary to prevent further disruptions to natural ecosystems.

Future challenges for water hazard early warning systems

Researchers have reviewed early warning systems (EWS) for water hazards, such as flash flooding, landslides, river flooding and coastal flooding.
