What are the disadvantages of online learning?

One pair of eyes is harmful, and the other pair will delay your study time. After all, our primary school students are not strong in self-control and discrimination. There are not a few people who play truant or truant because they are obsessed with the internet. The most important thing is that surfing the Internet is harmful to your eyesight. The eyes are the windows to the soul. What is more important than the window to protect the soul? Surfing the Internet deprives us of the opportunity to get close to nature. Since the advent of the internet, we have no interest in facing the cold monitor and mouse every day. Doing so is not only harmful to our health, but also harmful to us when we sit in front of the computer for a long time and receive too much radiation. Playing games online is not good for primary school students either. Playing online games will make people addicted to it, wasting time, spending money indiscriminately, neglecting their studies and wasting their time. Nowadays, it is not uncommon for people who stay at home for days and nights because they are addicted to online games, and it is not uncommon for games to be played until the early hours of the morning. It's easy to make some irresponsible friends online. There are thousands of people, and there are many no three no four people on the Internet. It is precisely because of the virtual network that we are easily confused when making friends. Dealing with such people for a long time will not only affect your study, but also get into bad habits. According to the survey, among the more than 30 million netizens in China, there are 6 million young netizens. A sample survey of primary and secondary school students by Tianjin Academy of Educational Sciences shows that 64% of primary and secondary school students have online experience. Nanyang City/KLOC-Ren Mou, a 0/5-year-old girl, met the netizens in Xichuan County of this province when chatting online. 2001September 18, Ren came to Xichuan County, more than 0/00 kilometers away, to meet netizens. However, after coming to Xichuan County, netizens did not know where to go. At the end of the day, Ren ran out of money. The next day, Ren got into the Internet cafe and went online to look for netizens. A whole day passed, but the netizen still didn't show up. In the middle of the night, Ren, who had no money to pay the Internet fee, had to stay in the Internet cafe. At the time of the "crisis", Kim, a 7-year-old boy/kloc-0 who also surfed the Internet in the Internet cafe, paid off the Internet fee for Ren, invited Ren to eat, and then took Ren to the suburbs for obscenity. Fortunately, he was found. After the incident, Kim was sentenced by the Xichuan County Court for attempted rape. This is an extreme example of teenagers indulging in surfing the Internet. Xu, director of the Cardiovascular Department of Jiangxi Provincial People's Hospital, believes that long-term addiction to stimulating computer online games makes people's brains highly nervous. Over time, it is likely to lead to the phenomenon of "over-restraint" and weaken the "focus of excitement" outside, and people will be indifferent or even numb to the surrounding things, leading to autonomic nervous disorder, which is manifested as sweating, impatience, rudeness and excitement. Ophthalmologists also remind that more than 60% people who surf the Internet for a long time will feel eye fatigue, blurred vision, dry or congested eyes, photophobia, acid swelling, elevated intraocular pressure, headache and even inattention, which will lead to retinal detachment in severe cases. In the Spring Festival of 2002, many young people in Beijing chose to spend the Spring Festival in Internet cafes. As a result, the number of people who feel tired or uncomfortable due to excessive internet access has surged.

The strong attraction of the online world to children and the mixed quality of the online world have indeed brought great difficulties to children's education. Moreover, in order to survive, parents have to deal with all aspects of things, and it is difficult to spare a lot of time to educate their children. However, for the healthy growth of children and the smooth crossing of the Internet, parents must overcome all kinds of difficulties, strive to "drive" the network direction that dual children need and make more efforts for their children.

First, according to a survey, many primary school students have become small "internet addicts", addicted to the Internet, spending 90% of their time on online games, becoming prisoners of the Internet and obsessed with "Internet cafes" and "chat rooms". Not only did he delay his study, but he even committed a crime. According to Guangzhou Daily in April 2000, a 65,438+05-year-old middle school student killed his cousin in order to play online games "casually" and take possession of her computer.
