Step-by-step explanation:

Answer:

The COVID-19 has resulted in schools shut all across the world. Globally, over 1.2 billion children are out of the classroom.

As a result, education has changed dramatically, with the distinctive rise of e-learning, whereby teaching is undertaken remotely and on digital platforms.

Research suggests that online learning has been shown to increase retention of information, and take less time, meaning the changes coronavirus have caused might be here to stay.

While countries are at different points in their COVID-19 infection rates, worldwide there are currently more than 1.2 billion children in 186 countries affected by school closures due to the pandemic. In Denmark, children up to the age of 11 are returning to nurseries and schools after initially closing on 12 March, but in South Korea students are responding to roll calls from their teachers online.

With this sudden shift away from the classroom in many parts of the globe, some are wondering whether the adoption of online learning will continue to persist post-pandemic, and how such a shift would impact the worldwide education market.

Answer:

The COVID-19 pandemic has changed education forever. What do you think? Which one is better--Online or offline learning?5 or 10 years ago, this shift would have been very painful, mainly because internet bandwidth was required for live, video classes were not available, or was just too expensive. Today’s internet bandwidth made this a reality, however, online teaching has its own set of challenges.If offline traditional methods of teaching are applied online, they can jeopardize (or limit) the success of the training.

Most schools or other institutions struggle with these since neither their teaching material addresses this nor have they had training on this.

The Pandemic has changed the education sector; it has pushed optimization in delivery methods. Schools and education institutions have been forced to move online. A new normal has been created and it is teaching online. While a lot of institutions have moved online by buying licenses for video conferencing tools, the question is, have they moved online?

If offline traditional methods of teaching are applied online, they can jeopardize (or limit) the success of the training.

Various issues come in when moving offline to online learning, how does one provides informal social interactions, how to ensure student attention, or even how to ensure active participation? Most schools or other institutions struggle with these since neither their teaching material addresses this nor have they had training on this.

Major issues

If one sees the impact of Covid-19 globally, at its peak 95 per cent+ learners were affected with over 1 billion learners affected in absolute terms. This ensured that learners moved from offline methods of delivery to online and, more so the shift was quick.
