A bomb threat caused the evacuation of parts of Facebook's headquarters in Menlo Park, Calif. on Tuesday, prompting a large police response. The evacuation came around 6 p.m. on Tuesday. Police later gave the all clear.According to KGO-TV, a tip was received by Crime Stoppers in New York, and relayed to authorities in California. The phone call was anonymous and no other details were shared. Many of Facebook's 33,606 employees work out of the company's Menlo Park headquarters. An FBI spokesperson told CNN that a few buildings were evacuated, but all staff members are safe and were allowed to return to the buildings. 661

A disproportionately large number of poor and minority students were not in schools for assessments this fall, complicating efforts to measure the pandemic’s effects on some of the most vulnerable students, a not-for-profit company that administers standardized testing said Tuesday.Overall, NWEA’s fall assessments showed elementary and middle school students have fallen measurably behind in math, while most appear to be progressing at a normal pace in reading since schools were forced to abruptly close in March and pickup online.The analysis of data from nearly 4.4 million U.S. students in grades 3-8 represents one of the first significant measures of the pandemic’s impacts on learning.But researchers at NWEA, whose MAP Growth assessments are meant to measure student proficiency, caution they may be underestimating the effects on minority and economically disadvantaged groups. Those students made up a significant portion of the roughly 1 in 4 students who tested in 2019 but were missing from 2020 testing.NWEA said they may have opted out of the assessments, which were given in-person and remotely, because they lacked reliable technology or stopped going to school.“Given we’ve also seen school district reports of higher levels of absenteeism in many different school districts, this is something to really be concerned about,” researcher Megan Kuhfeld said on a call with reporters.The NWEA findings show that, compared to last year, students scored an average of 5 to 10 percentile points lower in math, with students in grades three, four and five experiencing the largest drops.English language arts scores were largely the same as last year.NWEA Chief Executive Chris Minnich pointed to the sequential nature of math, where one year’s skills — or deficits — carry over into the next year.“The challenge around mathematics is an acute one, and it’s something we’re going to be dealing with even after we get back in school,” he said.NWEA compared grade-level performance on the 2019 and 2020 tests. It also analyzed student growth over time, based on how individual students did on assessments given shortly before schools closed and those given this fall.Both measures indicated that students are advancing in math, but not as rapidly as in a typical year. The findings confirm expectations that students are losing ground during the pandemic, but show those losses are not as great as projections made in spring that were based in part on typical “summer slide” learning losses.A November report by Renaissance Learning Inc., based on its own standardized testing, similarly found troubling setbacks in math and lesser reading losses.The Renaissance Learning analysis looked at results from 5 million students in grades 1-8 who took Star Early Literacy reading or math assessments in fall 2019 and 2020. It found students of all grades were performing below expectations in math at the beginning of the school year, with some grades 12 or more weeks behind.Black, Hispanic, American Indian and students in schools serving largely low-income families fared worse but the pandemic so far hasn’t widened existing achievement gaps, the Renaissance report said.NWEA said that while it saw some differences by racial and ethnic groups emerging in its data, it was too early to draw conclusions.Andre Pecina, assistant superintendent of student services at Golden Plains Unified School District in San Joaquin, California, said his district has scrambled to stem learning loss by issuing devices to all of its students, but the district continues to struggle with connectivity for students at home.Students who are typically 1.5 grades behind are now two grades behind, he said.“We’ve really just gone back to the basics where we’re focusing on literacy and math. That’s all we do,” Pecina said.“I feel like we’re trying our best,” he said. “Our students are engaged, but it’s not optimal. The learning environment is not optimal.”___Associated Press reporter Jeff Amy contributed from Atlanta, Georgia. 4028

A college student from Georiga's jail sentence was reduced from four months to two months on Tuesday in the Cayman Islands after she and her boyfriend violated strict COVID-19 measures last month.According to The New York Times and CNN, the Cayman Islands Court of Appeal reduced 18-year-old Skylar Mack and her 24-year-old boyfriend Vanjae Ramgeet's prison sentence, saying the initial sentence "was not appropriate."Last week, Mack and Ramgeet were sentenced to four months after they both violated the island's mandatory two-week quarantine.Per the Associated Press, Mack arrived on the island on Nov. 27, but on Nov. 29, she broke quarantine by leaving with her boyfriend to attend a water sports event.According to The Times, Mack and Ramgeet initially pleaded guilty to breaking the quarantine rules and were to complete 40 hours of community service. They were also fined ,100.But last week, the prosecutor appealed the ruling saying the sentences were too lenient and a judge sentenced to four months in jail.The Cayman Compass reported that Mack nor Ramgeet plan to appeal the Court of Appeal's ruling. 1121

A growing number of countries are banning travelers from the United Kingdom after a new coronavirus variant was found there.A variant or mutation happens when the genetic structure of a virus changes and this is common.The variant first appeared in September. Health experts have found it is more infectious than the original virus.“Let me tell you what, there is no evidence of nor reason to believe, it is not any more lethal or any more dangerous than the normal coronavirus, no evidence to suggest that, no reason to believe it,” said Admiral Brett Giroir, Assistant Secretary for Health at the Department of Health and Human Services (HHS).The variant has already been found in Australia, Denmark, South Africa and the Netherlands. Italy reports it has at least one patient infected with the mutation.While the U.K. works to control the new variant, several countries have banned flights coming from there, as well as countries where they've seen such infections.Despite the mutation, health officials remain adamant that it's important to get the COVID-19 vaccine.“There is also no evidence to suggest nor reason to believe that it would evade our vaccines that we have right now. Remember, our vaccines developed antibodies against multiple parts of that spiked protein, not just one that's the mutated one, so we are very encouraged about that,” said Giroir.A U.S. travel ban that began in March regarding the U.K. is still in place. 1449
