Even if there is no on-site instruction, knowledge can be conveyed. Math-Youtuber Daniel Jung explains how this works.

As of this Monday, most schools in Germany will be closed due to the corona virus. Most teachers are now faced with the question of how they can still convey content and provide teaching materials to their students. Daniel Jung operates a YouTube channel on which he has been providing explanatory videos for math since 2011. His channel “Math by Daniel Jung” has more than 600,000 subscribers and his videos have been viewed more than 200 million times. He is also the author of the book “Let’s Rock Education – What School Must Learn Today”.


SZ: Mr. Jung, the school closings are now the Opportunity for digital lessons?

Daniel Jung: As always in crises, there are opportunities. And the school closings are a huge opportunity. Perhaps schools and teachers will now proactively use the digital products and learning opportunities that are already there. It’s an educational jungle out there on the internet. There is an unbelievable amount of good quality videos on YouTube that explain content. You can see them wherever you are.

Doesn’t the social component of teaching get lost?


Even on YouTube there are simple comment functions that you can use to exchange information quickly and easily. And there are various platforms through which you can network or work together on documents. You don’t even have to be a big tech nerd to do that. Knowledge is not only consumed passively.

Will the teachers even become redundant in the end?

But on the contrary! You always need someone who structures and leads the process and also someone who can answer any questions that remain unanswered.

Interview in the morning

This series of interviews is devoted to current topics and will appear on SZ.de from 7.30 a.m. on Monday to Friday. All interviews here.

What can teachers now learn from the digital offerings that already exist?


The students are not on YouTube, Snapchat, Instagram or Tik Tok for nothing. These platforms are always stable and are very easy to use. We have to pick up the students. If everyone is on YouTube, let’s learn together. Due to the school closings, the young people will spend even more time on these offers than they already do. And I think at the moment the young people there tend not to consume any knowledge content.

Maybe teachers are also scared. For example, before violating data protection regulations.

That is certainly an issue. Precisely because many American companies do not take data protection very seriously. Here a framework is needed to ensure that teachers are legally on safe ground.


Certainly not every teacher wants to be exposed on YouTube. We all know that what is on the net never goes away.

Not everyone has to start putting YouTube videos online themselves. There are many good explanatory videos for each subject. You can also tell students to look at them. Basically, I’m happy about every teacher who offers tutorials. The more of it, the greater the likelihood that users will see it in their feed. And when teachers convey knowledge on the Internet, students can at least be sure that the content is correct.


Can you assume as a teacher or as a school that all students have the necessary technical requirements at home? That is also a privilege.

No, you cannot assume that. There are probably still many who do not have an electronic device or do not have the appropriate access to consume a video or a stable live stream. Maybe you have to start a discussion about why stable internet cables and devices are not a problem anywhere in the world, only we have a hard time. That means a lot has to happen relatively quickly now.
