Recent，Global Management Consulting Company McKinsea Silicon Valley Office Global Education Practice Manager Emma Dorn (Emma Dorn) and others published an article on McKinsey's official website to point out，Although American teacher、Management and parents are trying to maintain their studies through online education，But it seems that it can not ensure that it provides the same teaching quality as offline classrooms。And，In terms of income level and academic performance，There are always obvious gaps between white students and African -American and Latin students，The academic gap is even more prominent。School closure will not only cause students to varying degrees of academic losses，It will even cause more students to drop out of school，It will also affect its future economic income，Therefore, the overall economic growth and equilibrium level of the United States Bet365 app download are affected for a long time。

Over the past few decades，We rarely see any improvement of the above -mentioned student group academic performance.。African -American and Latin students' grades usually lag far behind white students in the same grade，There are very few students in the low -income family in the excellent student group。

This article creates a data model，For white family students from relatively high income and low -income families、African -American、Latin three types of students from three types of students remote online learning time and effect differences revealed，Low -income family、African -American and Latin students are more difficult to obtain high -quality long -range learning resources or beneficial learning environment than white students，If you are not disturbed, a quiet space、No need to share with others、High -speed network and parents' learning supervision，Caused by losses than university karma。According to Curriculum Associates， LLC) data provided by)，Only 60%of low -income family students will receive online guidance Bet365 app download regularly，and this proportion of high -income family students is 90%。Affected by the epidemic，Many disadvantaged students have to leave school。It is estimated that 2%-9%of high school students will drop out of school due to the new crown epidemic and school closure，that is 232,000 to 111,100 to eleven grades。

　　The economic impact of out of school and dropout

The negative effects brought by the rate of losing school and high dropout rate are difficult to easily eliminate in the short term。The impact caused by the epidemic is likely to be derived into long -term damage to individuals and society。Due to the possible secondary epidemic affected，Large -scale offline classroom may not be restored until January 2021。

Model calculation display，Average lifelong income of future graduates will decrease by 6.1 million to 82,000 US dollars (calculated from the US dollar value in 2020，equivalent to one year of unemployment)，This is just the impact caused by the out of school caused by the new crown epidemic。Where，The loss of African and Latin students will be greater。Assuming that the working life of white graduates is 40 years，It earns less $ 1348 each year (decreases bet365 live casino games 1.6%)，and non -American graduates will earn less than $ 2186 (decrease 3.3%)，Spanish graduates earn less than 1809 US dollars (decrease 3.0%)。It is estimated，This will cause the entire K-12 student group to lose the losses of 110 billion U.S.，Among them, US $ 98.8 billion may be related to out of school，and the remaining $ 11.2 billion is related to the rise in the dropout rate of colleges and universities。This is not just an economic problem，It also involves various problems such as society。Multiple studies believe，The higher education level of residents will improve the level of health、Reduce crimes and increase political participation。

　　Blowing the action number angle

These numbers are alert，But it is not unavoidable。If the United States can quickly take effective measures，It is possible to avoid the worst results。The current new crown epidemic may make the educational injustment of educational injustice under the existing traditional offline education framework。So，American education authorities urgently need to take effective measures to support vulnerable students。If most students bet365 live casino games are allowed to continue using free online learning resources，Innovative schemes that encourage students to encourage students in summer，Including cooperation with institutions that host summer camps and youth training programs，Expand the number of students participating in the summer project，Invite companies to help choose volunteers as candidates for mentors and conduct necessary training。For example，Tennessee is recruiting 1,000 college students to guide students with backward grades，New York State will hold a remote summer school for 17,7700 students (44,000 students in 2019)。

Regardless of the epidemic，Teachers need to fully learn how to improve the teaching effect，To this end, it is necessary to provide teachers with effective remote guidance training。At the same time，You also need to cooperate with parents to create a good family learning environment for students。other，We also need to call on students to use social and mental health services to exclude psychological pressure caused by the epidemic，and ensure that all students have long -range learning infrastructure (such as laptops、tablet Bet365 app download computer and smooth broadband)。

Significant gap between students' academic performance and their negative overflowing effects The problem of prominent issues Since receiving attention in 1966，It has not been effectively resolved，and the new crown epidemic may exacerbate this situation。Different income families and ethnic students achieved grades，Not only does the United States pay hundreds of billions of dollars in economic costs，It also affects the improvement of social cohesion。It's time to deal with the challenge。
