Answer:

Though the world has dealt with other pandemics in the past, COVID-19 has been spreading fast. Additionally, the virus is quite contagious and can pass between people before any symptoms appear.

 

The worry around the virus, and the effort to contain it, stems from a lack of previous experience with it. Since the virus is previously unknown, highly contagious, and passes easily from one person to the next, public health and government officials around the world are working hard to contain the spread of the virus while a vaccine is still unavailable.

Why Schools Are Closing

As part of the effort to contain the spread of the coronavirus, public spaces such as schools, universities, and offices are closing down so that people can stay at home and prevent further spread.

 

In countries, such as China, where testing and quarantine measures were taken, the spread was able to level out. Measures that are taken to slow the rate of infection include social distancing, limits on event sizes, and home quarantine when necessary.

 

Closing schools and offices ensures that people can limit their interactions with others and slows the spread of the virus while the healthcare system copes with the pandemic.

What Are The Alternatives When Schools Close

1. Online learning

 

Many schools and universities are opting to continue their normal classes on online platforms. This includes the use of online tools, such as group video programs, that allow teachers and students to meet and conduct classes over the internet.

 

Another way that students are continuing their studies is through distance education, which uses online programs that replace instructors with educational material that students study on their own.

 

An example of distance learning would be online classes or videos which students use on their own time, as opposed to meeting live with the teacher and other students.

 

However, not all schools and universities were able to make it online and may soon be closed forever. Institutions like University of the People – an online, tuition-free, US accredited university – have always been online. Because of that, students can learn with us anywhere, anytime. We don’t have a physical campus, so our doors are always open! Nas Daily, an impactful social media influencer, talks about this, how students are demanding more value and lowers costs for their collegiate studies, and other higher education news in his video below.

 

 

 

 

2. Free online programs

 

In light of the pandemic, and the interruption of normal education, many online educational platforms have been advertising free educational tools for students around the world who are stuck at home.

 

Companies such as Scholastic and Coursera are advertising free online courses to encourage students to continue learning at home, and websites such as Unesco and Openculture are creating lists of free online courses and resources for anyone who wishes to learn at home
