For months now, public health experts and educators have been lamenting the long-term impacts of remote learning.In May, researchers estimated that by the beginning of this academic year, the average student would lose a third of their reading progress and half of their math progress from the previous year.“That was kind of assuming kind of a worst-case scenario,” said Beth Tarasawa, executive vice president of Research at NWEA, a nonprofit standardized testing company that released its findings from this fall’s assessment.“Kids remarkably have weathered pretty well in reading and those patterns both in the cross-sectional as well as the longitudinal studies really kind of highlight some good news,” said Tarasawa.But their analysis of data from nearly 4.4 million U.S. students in grades 3-8 found average scores for math were lower – between 5 and 10 percentile points– for students this year as compared to same-grade students last year.The findings represent some of the first empirical measures of how the pandemic has affected student performance.“We're moving slower, which means that we're covering less material over a certain period of time,” said fifth grade teacher Cara Koen.Koen, who has been teaching reading and math for more than two decades, says remote learning has forced her to slow her pace, especially with math.“There may be difficulties with Wi-Fi and different things from day to day” said Koen. “You have to slow down in order to reach all learners.”Kimberly Berens is a child development expert, educator and the author of "Blind Spots: Why Students Fail and The Science That Can Save Them."“Spending more time on repeated reinforced practice of skills to mastery so that when kids have gaps in instruction that are inevitably going to happen from school closures, kids getting sick or pandemics then kids will be more resilient,” said Berens.Still, NWEA’s data set is incomplete. One in four students who they tested in 2019 were missing from this year’s assessment.“They were much more likely to be African-American or LatinX or Hispanic,” said Tarasawa. "They were more likely to be from high poverty schools and they were more likely to be lower achieving in the first place.”That means that while the new data suggests some promising outcomes, we still don’t know just how severely the pandemic is impacting minority and socio-economically disadvantaged students. 2413

FORTVILLE, Ind. — A central Indiana superintendent gave students some fun "assignments" to complete on the first snow day of the year. With the institution of virtual learning during the COVID-19 pandemic, many families thought snow days to be a thing of the past for students. But when snowfall led to messy roads across parts of Indiana, there were still several dozen schools that chose to either delay or cancel classes.Dr. Jack Parker, Superintendent at Mt. Vernon Community School Corporation sent a letter to parents canceling in-person learning in favor of virtual learning — but not the type of virtual learning typically seen amid the pandemic.The note to parents went on to give two assignments that included playing in the snow and throwing snowballs."Students will use the scientific process in planning appropriate clothing to remain warm and dry while spending time outside. Once the hypothesis has been identified, and appropriate attire has been secured, students will be expected to test their theory by going outdoors and playing in the snow," Parker's note read. "Step two of this assignment will be to practice the skills of estimation and measurement when throwing snowballs at one another while maintaining a minimum of 6' of distance with others outside of your household. When being with said snowball, students are expected to practice their social skills and to use their good words."He even gave students a chance to earn some extra credit. "Extra credit can be earned by helping to shovel sidewalks and/or driveways," Parker wrote.And of course, students who aren't feeling well were given an alternate assignment to complete."Students who are not feeling well will be expected to complete the alternative assignment of resting indoors and drinking plenty of fluids," the letter read. 1822

Four days after a massive earthquake?killed at least 347 people on the Indonesian island of Lombok, a 5.9 magnitude tremor hit the island, sending frightened residents onto the streets.Thursday's seismic event follows a 6.9 magnitude quake Sunday that flattened homes and stranded thousands of people on Lombok's northern coast and the nearby Gili Islands.The northern part of Lombok is more residential and less developed than the resort-filled south. Thursday's quake could be felt on Bali, another popular resort island in Indonesia.Endri Susanto, who runs a nongovernmental organization assisting with relief efforts, said the earthquake felt very strong in Mataram, a city on Lombok's west coast. 714

For many restaurants, like Sam's No. 3 in downtown Denver, the experience is part of what they serve.“We were built to serve people inside,” said Sam Armatas, owner of the restaurant. But with ever-changing COVID-19-related dining restrictions and winter looming, delivery is becoming a more enticing option for customers. And for Sam’s No. 3, delivery apps make that easy.“We’re able to continue to serve our product, try and stay relevant as far as people eating our food,” Armatas said. The diner has three locations. At two of them. 90% of orders are now made through delivery apps. This can be convenient for customers, but costly for some of the restaurants. Exposure to consumers has it's price.“There are negatives. I mean they take a commission but those commissions are now capped,” Armatas said. “You're pretty much at the mercy right now of the delivery services hoping to get your food out hot, tasty and attractive still.”He chooses to stick with the apps to get his food out there to people, while for other restaurants, the cons of delivery apps outweigh the pros.“At the moment, we will not use any third-party services at all for delivery,” said Giles Flanagin, Co-founder of Blue Pan Pizza.Blue Pan relies on their team of 17 part-time in-house delivery drivers, instead.“In-house delivery can work cost-wise, if the restaurateur is willing to put in the time and the effort to build that specific revenue stream,” he said. “If I use Doordash, Grubhub, or Postmates and I pay a 25% commission, not only am I losing all of my profit, but I’m in the red.”Flanagin said Blue Pan has been using their own delivery since they opened in 2016. They tried a delivery app to serve areas farther away, but too many bad experiences led them to cancel.“When a customer gets a pizza from a third-party delivery and it’s a poorly delivered experience, they don't look at Grubhub or those businesses. They call us and they're upset,” he said. For him, the reputation of his business and their food is important.“I think the best way I can summarize making a decision to use a third-party delivery service is buyer beware. This is our experience and I’m not saying it's everyone's experience,” Flanagin said.It’s a balancing act for these apps like Uber Eats and Grubhub. They have a business to run, but they also have to consider the restaurant and the driver.“Restaurants are just trying to find any possible ways to break even or minimize their costs,” said Alexandre Padilla, an economist and professor at the Metropolitan State University of Denver. “It’s a very complicated issue where the apps are providing a service where they are trying to attract drivers to meet the increase in demand due to the pandemic.”As potential customers opted to stay home in March when lockdowns began, the demand for drivers went up.Gig economy workers like Julian Rai almost completely switched from rideshare apps to delivery apps backs in March.“Remember that we are basically waiters on wheels, we’re servers on wheels,” he said. “If it weren't for tips, we’re making less than minimum wage just from the delivery fee. Like a waiter, it’s very similar to what a server would make before tips. So at the end of the day, well over two thirds to three fifths of my income comes from tips.”Rai explained they may spend 20 to 40 minutes on one single order so, reasonably, they ask for some compensation for that.It’s a tough balancing act between restaurant, app, and driver.“I don’t know that that balance has been struck yet,” Rai said.For now, delivery is a means to an end for these restaurants that thrive on providing quality food and a great dine-in customer experience.“Our business model isn't built to survive this way,” Armatas said. “We’re just trying to stay relevant, trying to survive. If we can get through winter great. That’s the hope, the dream, is that by March we’re still here.” 3901
