Because under the epidemic, Brazil is about to face a repeat situation, so whether to conduct offline education or online education has become a dilemma for Brazil. Because if offline education is carried out, it may lead to the further expansion of the epidemic in Brazil, and even this time it will hurt the younger generation in Brazil. However, if online education is carried out, some areas in Brazil cannot enjoy good online education because of poor public facilities and incomplete network coverage.

Now that Brazil is about to resume classes, the mayor of Rio allowed private schools to resume classes before, but the court rejected this judgment. The court's decision made many parents breathe a sigh of relief, because we know that the epidemic situation in Brazil is very serious now and it has become the second largest epidemic country in the world. Although Brazil has slowly entered the fifth stage of economic restart, it means that many public places are slowly opening up. The mayor said that if private schools can keep clean, disinfect regularly and let students observe the defense work, they can actually resume classes. However, despite this promise, many parents are still worried, because if the epidemic prevention can be done well, the epidemic situation in Brazil will not be so serious. Even if their children go to class, even if the danger is small, it will be infinitely magnified in the eyes of parents.

However, classes in Brazil have been suspended for a long time now. Since the COVID-19 epidemic began to ravage Brazil in March this year, classes have been suspended all over Brazil. At that time, when to start classes again and how to start classes in a safe situation were problems that the whole country had to face. Now, just like the Rio municipal government, all governments want to resume classes when the epidemic is not completely controlled, but in fact they have to have difficulties.

If Brazil chooses online teaching, it will greatly increase the difficulty of online education, because once online teaching is carried out, almost all teaching procedures will be changed, not only for these teachers to adapt, but also for students to adapt to this new teaching mode. At the same time, due to Brazil's incomplete infrastructure and incomplete network coverage, many areas may not be able to keep up with the progress of teachers' online teaching because of network or infrastructure problems. Before, the Brazilian Ministry of Education changed all schools in the country into online courses, but according to statistics, more than 20% students in various regions of Brazil did not participate in online courses, which shows that the efficiency of online courses is very low.
