New data shows that those who use Duolingo — a popular language app — can learn the equivalent of four semesters of university study. The app is free for all, and parents and teachers say it is a good supplement for students of all ages who are learning from home this fall.Averill, 10, is quite the Duolingo master. Her Spanish teacher recommended the app to pair with her in class lessons a few years back. Averill took that one step further.She's currently learning Korean. When she masters that, it will be her third language."My dad is Korean, and so my grandparents speak Korean," Averill said. "I'm trying to learn it because we're planning a trip to Korea to visit some relatives and I'm trying to learn it so I can speak to them a little bet,ter than I can right now."She likes to take what she's learned and practice on her grandparents. So far, she says, she's doing pretty well.Korean and Spanish are two of the 39 featured languages on Duolingo. This spring, when COVID-19 sent America into lockdown, new users flocked to the app. Dr. Cindy Blanco is a learning scientist at Duolingo."Our new users spiked 66%, which in any other time would be enormous but the spike continued the rest of the month," said Dr. Cindy Blanco, a learning scientist at Duolingo. "Our new user growth in March was 113%, which is unprecedented — kind of the word of the year."People were also downloading the app to keep their language skills sharp and because teachers needed help."The most important thing to not fall behind in a language course is to keep getting in front of that language," Blanco said.As a Doctor of Linguistics, Blanco is a Duolingo user herself. She's currently trying to keep up with her Russian. She's already well-versed in Spanish, French, Catalan, Italian and American Sign Language.Blanco says Duolingo offers all sorts of content, including lessons, short stories, podcasts, and seven a virtual language practicing event. Because Duolingo is app-based, it means users can access it from anywhere, anytime."It's more important than ever that we create products that can meet people where they are and where they are is at home with small handheld devices," Blanco said. "So, how can we get language learning literally in your hands?"It's also fun. The program moves away from textbooks and worksheets that many find monotonous, especially when it comes to language."We often associated language-learning with dry high school classes of textbooks and worksheets," Blanco said. "So, to see something that's fun, that you like doing, you're deceiving yourself. 'Well, I can't possibly also be learning, I'm enjoying it too much.'" 2655

North Korea has tested a "newly developed ultramodern" weapon in an event supervised by leader Kim Jong Un, state media said Friday, amid faltering nuclear disarmament negotiations with the United States.Very little is known about the weapon or whether it is even new, but the test is the latest sign that Pyongyang is prepared to return to a more militaristic relationship with Washington if talks continue to go poorly."He's tiptoeing towards a more aggressive posture in negotiations with the US and he's signaling that he's not going to give way and can simply return to his old practices if (the US) don't change their approach," Josh Pollack, senior research associate at the Middlebury Institute of International Studies at Monterrey, told CNN.North Korea's state news agency KCNA announced the test on Friday morning, providing no details on the location of the event and little information about the weapon itself other than it was "tactical" and had been commissioned "personally" by Kim's father and predecessor, Kim Jong Il.A South Korean government source with military knowledge told CNN the weapon was likely a piece of long-range artillery "likely to be a multiple rocket launcher.""As it is a tactical weapon test, we do not view it as a North Korean military provocation," the source said. 1320

Her well-being, the alert said, was at risk.CNN has reached out to Mexico's attorney general and the federal police for comment, but has not heard back.Esterly was expected to be extradited back to Pennsylvania. 1027

NEW YORK (AP) — Facing a potentially ruinous wave of new sex-abuse lawsuits, the Boy Scouts of America is increasing its annual youth membership fee by more than 80%.The group says the move, which has dismayed many of the Scouts' adult volunteer leaders who warn the increase is prohibitively steep for some, is needed to meet rising operating costs, notably for the liability insurance that covers all official Scouting activities.For years, the BSA has been entangled in costly litigation with plaintiffs who said they were abused by scout leaders in their youth. Hundreds of lawsuits may lie ahead with the recent enactment of laws in New York, New Jersey, Arizona and California making it easier for victims of long-ago abuse to seek damages.The fee increase, disclosed to the Scouts' regional councils last week, seeks to relieve some of the financial pressure. As of Jan. 1, the annual membership fee for 2.2. million youth members will rise from to ; the fee for adults will rise from to , the Scouts said. The increases could generate more than million in additional funds in the coming year.The BSA says it's exploring "all available options" to maintain its programs and has not ruled out the possibility of declaring bankruptcy.As part of that process, the Scouts said they are consolidating their departments and recently eliminated more than 35 positions at its National Service Center.The BSA's current youth participation is down from more than 4 million in peak years of the past. It has tried to offset the decline by admitting girls, but the membership rolls will take a big hit as of Jan. 1, when the Church of Jesus Christ of Latter-day Saints — for decades a major sponsor of Boy Scout units — cuts its ties with the BSA and launches its own global youth programs.In its announcement, the BSA made no specific reference to the sex-abuse litigation but made clear the fee increase was driven by insurance costs."Unfortunately, the cost of liability insurance we must carry to cover all Scouting activities has increased dramatically over the past several months, and the organization is no longer able to offset the cost of insurance," the BSA said.In addition to insurance, the BSA said, membership fees cover other "essential services" such as background checks for adult leaders, program development and updated youth protection and safety training.The national fees do not cover costs for uniforms and handbooks, which can easily exceed 0 per year.Scores of the Scouts' volunteer adult leaders weighed in on the fee increase in comments on a blog operated by the BSA's Scouting Magazine. Several of the leaders warned that the increase would be financially burdensome for low-income families and might drive them away from scouting.The BSA insists that the scouting remains a good value, compared with many other organized youth activities."While most extracurricular activities are seasonal, Scouting is a year-round program that remains one of the most valuable investments we can make to support young men and women," the BSA announcement said.The organization says it will strive to assist families who feel they cannot afford the higher fees. It announced creation of a fund, supported through donations, to provide financial assistance.Many of the volunteer leaders commenting on the blog were upset by the timing of the announcement. It came after Scout units had already begun collecting fees for their 2020 registration renewal process and setting their budgets for the coming year."I am extremely disappointed in the handling of this increase," wrote John Guild, a Dallas attorney who has helped lead a Cub Scout pack and slammed the move for lack of transparency as well as its poor timing. Guild also questioned how effective the fee increase would be, contending that the BSA "is facing hundreds of millions of dollars is liabilities and tens of millions of dollars in legal fees."Jason Krut, who is active with a Pittsburgh-area Cub Scout pack, called the increase "unconscionable.""It reeks of incompetence and mismanagement," he wrote on the blog. "It will force children, leaders, and families away from scouting and to seek out BSA alternatives. "Brandon Boos, a leader of a Cub Scout pack in Worthington, Ohio, said the magnitude of the increase was understandable but he faulted the timing."The roll-out did not demonstrate the same high quality of character we are trying to instill in our Scouts," Boos wrote on the blog.In a subsequent email to The Associated Press, Boos said he still loves the Boy Scouts, plans to continue as a volunteer and hopes other parents do likewise.Donald Dement, a volunteer leader with his sons' Boy Scout troop in Frisco, Texas, said most of the parents would have no trouble affording the higher fees, while hard-up families would likely get assistance from their troops.Dement said some conservative families in Frisco continue to resent major changes made by the BSA in the past decade — these included opening its programs to girls, and admitting gays as scouts and adult leaders. One local troop, he said, made hats for summer camp last year emblazoned with "Make Scouting Great Again."But regarding the fee increase, he said most scouting families "will be understanding and accepting."The Boy Scouts filed lawsuits last year against six of its own insurers, saying they have improperly refused to cover some of the sex abuse liabilities incurred by the organization. The insurers say the coverage obligation is voided because the BSA failed to take effective preventive measures such as warning parents that scouts might be abused."We believe insurance companies should uphold their commitments by paying their share of claims," the BSA said in an email to The Associated Press on Thursday. "We remain in disputes with some carriers and look forward to a resolution that benefits victims and helps them on their journey towards healing." 5951
