Apple is fighting to take back the classroom.The company revealed on Tuesday in Chicago what it believes is the future of education. CEO Tim Cook and his executive team took the stage at Lane Tech High School to discuss "creative new ideas for teachers and students."Apple showed off a new budget iPad specifically targeted toward students. The 9.7-inch device -- the same size as the traditional iPad -- will cost 9.The new iPad works with the Apple Pencil to support art projects — similar to what comes packaged with the higher-end iPad Pro tablet. Apple also teased software features such as smart annotations to help teachers mark up papers, and augmented reality support which will "enable new ways to learn."Alleged leaks of the upcoming iOS 12 software have shown a "ClassKit" platform for developers to create puzzles, tests and lesson plans for students. Augmented reality integration is a good bet, too.Apple's education business has had its ups and downs. iPads and Mac computers were once the primary devices used in American schools. But in recent years, Apple's dominance has slipped. Now, Google's budget-friendly Chromebook laptops occupy nearly 60% of all devices in the classroom, according to research firm Futuresource. Apple devices make up just 17% of the education marketshare.Perhaps it has learned from its mistakes. In 2015, a Los Angeles school district planned to give every student in the city an iPad with preloaded curriculums. Wired reported that the program, which was expected to become a billion deal, fell apart.After a volatile few years, Apple said in 2017 that iPad sales for the classroom ticked up 32% after dropping the price for its entry-level iPad to 9. Apple also made small tweaks to make it easier for students to share in the classroom, such as removing its Apple ID requirement.To get ahead of Apple's news, Google announced on Monday its first tablet running Chrome 10: Acer's Tab 10. At 9 — the same price as the cheapest iPad — Google and Acer hope to bring the flexibility and versatility of the Chrome operating system to an even more portable device.This is Apple's first education-focused keynote in six years — and its second ever. The company hosted a digital textbook launch in New York City in 2012.Chicago is a fitting backdrop for its latest event. The city is home to one of the largest school systems in the United States, and Apple expanded its "Everyone Can Code program" late last year to teach more students its Swift programming language.It's unlikely, however, that Apple will reveal details about its next generation iPhone on Tuesday. But with its annual World Wide Developer Conference only three months away, we may hear some subtle software teases of what will land on iOS and OS soon.  2788

An eruption from the Kilauea volcano's summit shot ash and smoke into the air early Thursday on Hawaii's Big Island, and the resulting plume is expected to cover the surrounding area, according to the Hawaiian Volcano Observatory.Nearby residents are being asked to shelter in place if they are in the path of the ash plume, which the wind is carrying to the southeast of the volcano."Driving conditions may be dangerous so if you are driving pull off the road and wait until visibility improves," an alert from the observatory warned.Thursday's eruption is just the latest volcanic activity contributing to the nightmare on the Big Island since the volcano first went off May 3.An ash plume Wednesday rose roughly 12,000 feet into the air, and on Tuesday, the US Geological Survey issued a red alert, which means a major eruption is imminent or underway and ash could affect air traffic.It is not clear if this was a phreatic eruption, which US Geological Survey officials have been saying is capable of sending ash plumes as far as 12 miles away from the summit.These are steam-driven explosions that occur when water beneath the ground or on the surface is heated by magma, lava, hot rocks or new volcanic deposits, the USGS says. The intense heat may cause that water to boil and result in eruptions.The lava lake in the crater has been dropping since May 2, which increases the chances for a phreatic explosion, but it will be difficult to warn residents who may be in the path of such an eruption.Phreatic eruptions are "notoriously hard to forecast, and can occur with little or no warning," Hawaiian Volcano Observatory geologist Janet Babb said.While the ash being launched into the sky is not poisonous, Hawaii County officials have warned residents about toxic sulfur dioxide seeping out of 21 fissures caused by the volcano."Severe conditions may exist such as choking and inability to breathe," the county's Civil Defense Agency said Wednesday. "This is a serious situation that affects the entire exposed population."The-CNN-Wire 2051

An email sent to businesses and organizations across the country on Thursday appears to be a hoax, authorities from the New York Police Department said. According to NYPD's Twitter page, the email, which prompts victims to make a Bitcoin payment, is a scheme to either "cause disruption and/or obtain money."Police in New York said they have searched various places where the email has been sent, and no devices have been found. NYPD said they will continue to respond to calls for service if anyone receives a threat. Authorities in other states have conducted similar searches. Police in Tennessee said they believe the email originated from outside of the United States. The FBI issued the following statement: 746

Approximately two dozen white nationalists rallied in the nation's capital on Sunday, one year after clashes in Charlottesville, Virginia, left one person dead and elevated racial tensions in America.But they were vastly outnumbered by throngs of counterprotesters.The showing from "Unite the Right 2" participants fell far short of the hundreds that organizer Jason Kessler was expecting, based on his event permit application.Photos: 'Unite the Right' white supremacist protest and counterprotest in Washington, D.C.Kessler, who organized last year's "Unite the Right" rally in Charlottesville, blamed the low turnout on logistical issues and confusion regarding the group's transportation -- a claim echoed by at least two men who spoke to reporters. "People are scared to come out after what happened last year," one of the men added.A small stage and speaker system was set up in the park, where attendees stood silently and listened to a slate of impromptu speakers.They addressed the small group over the jeers of the anti-racist demonstrators, who chanted, "Nazis go home!" and "Shame! Shame! Shame!"The white nationalists left the park not long after they arrived, prompted by the sound of thunder and rain, and were whisked away in white vans. 1261

ARVADA, Colo. — An 11-year-old girl penned a letter to Santa filled with heartache, asking him to stop her “sadness” after losing her father and grandmother in a house fire over the summer.Brooklynn Alexander, 11, wrote her Christmas wish and dropped off her letter in Santa’s mailbox in her hometown of Arvada.Amber Klein built the mailbox to ensure Santa received every letter written by kids in Arvada before Christmas.“Every night, I send the letters off to Santa,” Klein said.While helping Santa read through the letters, Klein came across Brooklynn’s wish, a heartfelt letter raw with pain.“Santa, I’ve been suffering from depression and my anger issues have been bad lately. So, what I am trying to say is — I shouldn’t get presents and can you please stop my sadness,” Klein read in the letter.In July, a fire tore through Brooklynn's home, killing her father and grandmother. A neighbor rescued her from inside. She was put on a ventilator and spent more than a week at the hospital. The pain and anguish Brooklynn feels brought memories of Klein’s dad rushing back.“My dad passed away in a house fire and I just immediately wanted to protect her,” Klein said.Klein took to Facebook to track down Brooklynn. It didn’t take long for the two families to bond.“I told her about my dad and how he died,” Klein said. “I showed her the necklace that I wear that has my dad’s ashes in it and now Brooklynn wants the same thing.”Two lives, decades apart, found each other as Brooklynn learns to navigate her pain.“I feel like whether it be my dad or Brooklynn’s dad, that they brought us together,” Kelin said.Through tears, Brooklynn says Kelin’s story gives her hope that life will get better.Brooklynn has since written a second letter to Santa. Her wish list includes a body pillow, fluffy socks and a paint-set with watercolors. She's also asking for letters from the public to help bring joy back into her life.“It’s just really fun seeing letters from people that I don’t even know cause even though they don’t even know me, they care about the situation,” Brooklynn said.This story was originally published by Adi Guajardo on KMGH in Denver. 2158
