I. Positive impact

First of all, the new media culture spreads knowledge and information by high-tech means, and builds an encyclopedic information platform for people to consult, retrieve and download freely.

This makes young people's vision not only stay in the things and people around them, but also see current news, political and economic trends, culture and art in different regions and countries, enriching young people's knowledge.

Secondly, teenagers participate in cyberspace with the help of devices and terminals, and are free to express their feelings and interact with others, regardless of identity and geographical restrictions. The public is not only the receiver of new media culture, but also the creator of new media culture, and teenagers can expand the scope of communication in this way.

Finally, the new media culture fully embodies the respect and free interpretation of individuality. In the new media era, more and more grass roots have gradually entered the public eye, and everyone's personality has been fully respected, which provides a good platform for the free development of young people.

Second, negative constraints.

First of all, the new media culture is an open culture. With the help of the new media platform, people can freely express their views and opinions, which makes all kinds of information on the Internet mixed. Teenagers' discrimination ability is not strong, and they are easily impacted by negative information.

In addition, teenagers are in a rebellious period of youth development. If the information they receive from the new media is different from the education they usually receive, they will blindly trust their own judgments and affect the formation of the correct values of teenagers.

Secondly, the new media culture is a simple and convenient audio-visual culture. Teenagers receive information through quick browsing or video presentation, lacking their own thinking and opinions.

Nowadays, the new media culture presents everything that needs thinking in a more direct way. Along this line of thinking, teenagers will form a mindset, ignore thinking and belittle their thinking ability.

Third, almost everyone of teenagers today has a mobile phone and a computer. The convenience of new media enables teenagers to see everything on the internet as long as they have equipment.

This has led to a phenomenon that no matter when teenagers are surfing the Internet, during class, during recess, before going to bed, before getting up, and even when doing homework, they will study while surfing the Internet, which greatly reduces their learning efficiency.

Moreover, they also surf the internet in class, which seriously affects their class. Over time, teenagers will get used to this lifestyle and become dependent on new media, leading to lifestyle changes.

Renew educational ideas and actively respond to the challenges brought by new media culture;

1. First of all, we should correctly face the challenges brought by new media culture to youth education, actively update educational concepts, broaden educational horizons, adhere to the people-oriented educational concept, and pay attention to humanistic care for young people.

2. Secondly, we should attach importance to the dominant position of teenagers, combine their psychological characteristics, and educate them in a way that teenagers can easily accept.

3. Finally, we should give correct and effective guidance to teenagers, guide them to correctly understand and use new media, and stimulate their awareness of self-education.
