An educational platform that was created to help the nation's teacher shortage is now helping schools backfill during the pandemic."Elevate K-12" offers live instruction, and some districts say it's filling in the gaps for students.Eighth-grade science looks a lot different these days, at least in Louisiana's Caddo Parish Public Schools."We really are almost the districts in one," Caddo Parish Public Schools Chief Academic Officer Keith Burton said.Of the district's 61 schools, 65% are Title 1 schools, meaning they receive federal funds for having large concentrations of low-income students.While the district also has magnet and gate programs, there were some instructional gaps."We really struggled in the area, as most districts do around the nation with needing enough mathematics teachers — especially around the middle and high school area — as well as science and foreign language teachers," Burton said.The district discovered Elevate K-12 two years ago and now use their live teachers for 67 periods."Anywhere from seventh-grade math to Spanish II, Algebra II, in about every corner of our district," Burton said."If you look at the entire U.S. K-12 population, there are 58 million students, of which 50.8 million are in the public school system," said Elevate K-12 CEO and founder Shaily Baranwal. "In that, about 22 million are low-income. The teacher shortage problem specifically plagues the low-income neighborhoods. We work with some states in some zip codes where they can't even find a grade four math teacher."Baranwal grew up in Mumbai, and Elevate K-12 was born out of a business school project."I'm that one Indian that rebelled and said I do not want to do engineering," Baranwal said. "I've always followed my heart, followed my passion. I'm an extreme non-conformist, so I did not follow that path and got an early childhood teaching certification. I then worked as a preschool teacher in India, came to the U.S. to Michigan to get my MBA."She says she created the platform to solve one problem: the nation's teacher shortage."One of the school districts we work with in Georgia — when I was talking to the head of talent there, they did not have an Algebra I teacher for the last four years," Baranwal said. "So, what they had to do was they took the local priest and made the local priest get an Algebra I secondary certification so the local priest could then teach the class."Elevate K-12 now helps large and small school districts around the country, and it just so happens to be in a unique position to help those who have gaps because of the COVID-19 pandemic."This solution was not created to solve a COVID problem," Baranwal said. "The teacher shortage problem has been plaguing the U.S. K112 schools and districts and specifically the low-income neighborhoods for years. What COVID has done for us is accelerated the entire acceptance of live streaming instruction as a solution."They have a network of more than 2,000 teachers, and more than 300 are actively teaching now. All are certified and based in the U.S."We are shaking up the K-12 antiquated system in making people realize that you should not offer a class like German or cybersecurity or science or math, just because you don't have a teacher," Baranwal said. "Take those barriers away and use live-streaming instruction so the teacher can be anywhere in the country. Your kids can be where they are and still learning in a highly engaging format."Burton says Caddo Public Schools hasn't had to use it for reasons related to the COVID-19 pandemic as of yet, but they're in a position to, should they need it.He added that the students adjusted quickly, and some even prefer personal and private teacher-student interaction."Now I'm able to leave those classrooms and see students engaged see students learning," Burton said. "Many times, students are saying I'm having conversations with a teacher in Colorado or North Carolina, and those students are loving it. They really are." 3992

As disinfecting wipes and sprays fly off store shelves, companies are looking for new ways to keep surfaces coronavirus-free. Some are looking at repurposing UV light technology, a cleaning solution that’s been used for decades.Ava Robotics and the Massachusetts Institute of Technology partnered on a project to create a robot that uses UV-C light to disinfect large areas.“It was about a 4,000 square foot space. It was able to disinfect that in less than 30 minutes,” said Youssef Saleh with Ava Robotics.The purpose -- cleaning large, busy spaces of virus and bacteria, specifically coronavirus.“UV is not new. Robots are not new themselves,” Saleh said.“It's actually been in practice in hospitals for probably four decades plus,” said Dr. Eric Hill, the Chair of Emergency Services at Medical Center of Aurora. It’s usually used to sterilize rooms.“Anything that the light hits, it can kill. So it has to be in direct contact with the light beam and it has to be in contact for a certain period of time,” Hill said.“There are three factors of effectiveness of UV light, the first is the power itself,” Saleh explained. “Then there's the distance to the object that you're trying to disinfect, and then there is the amount of time.”"We cannot see it, it's the same kind of UV radiation you’d get from the sun,” Hill said. “It works by destroying the DNA and the RNA of the organism. And it doesn't affect just viruses, it affects bacteria, viruses, mold, and spores.”While it can kill germs, it can also do damage to us. UV light plays a role in diseases like skin cancer. “It is dangerous for humans to be in direct contact with it,” Dr. Hill said.That’s why the project with Ava Robotics and MIT also factors in safety for humans.“Safety elements have to be part of the solution, thought through, and understood,” Saleh said. The team is working on making the robot more adaptable to changing spaces, like warehouses, and potentially other large spaces like grocery stores and schoolsBut Hill says UV light isn’t a complete replacement for traditional cleaning methods.“It does not take the place of things like wiping something down,” he said. “But after you do that...adding in a UV light system can really hit in a broad area...and get all the microorganisms that were in there.”Hill also warns consumers that are interested in this to look at products closely.“Several hundred dollars is realistic for a good UV light system,” he explained. “We have seen much more of a demand of it, if you go on Amazon the amount of UV light products I’ve seen pushed out is incredible.” 2591

An 11th child has died and 23 additional children have become sick in connection with an adenovirus outbreak at a New Jersey health care facility, the state's Department of Health announced Friday.The children have weakened immune systems and other serious medical issues, and many of them require assistance to breathe and function. They became sick at the Wanaque Center for Nursing and Rehabilitation in Haskell, New Jersey.An ongoing investigation has revealed that not being able to separate the sick from those without symptoms -- in part due to "limitations in the facilities" -- is among the "major reasons for the outbreak being as severe as it has been," Dr. Shereef Elnahal, commissioner of the New Jersey Department of Health, said Friday.But after deaths and hospitalizations, the facility now has enough space to separate them."Up until this week, it has not been possible to completely separate those patients," Elnahal said. "But now, due to decreasing census at the facility, it is."On Thursday, health officials requested help separating those who are sick, putting out a statewide call for volunteers from New Jersey Medical Reserve Corps. The health department has required that the Wanaque facility finish the process by Wednesday."The fact that we are continuing to see new, confirmed cases at this point, despite all efforts toward strict adherence to protocols, has made the facility's layout limitations clear," Elnahal said in a statement this week.Citing "serious infection control deficiencies cited in ongoing inspections," the health department has also required the Wanaque facility to hire new staffers with expertise in infection control, including an infectious disease doctor.State health officials are prohibiting any new admissions to the facility, and requests to readmit former residents must be specifically approved. 1865
