Online Learning vs. Offline LearningAbstractBecause of the 2019 novel corona virus (2019-nCoV) epidemic, online learning is popular, while the development of science and technology for online learning provides the possibility. Online learning and offline learning comparison have become a hot topic. Their advantages and disadvantages also let people think deeply.After various investigations, it is concluded that although online learning is very popular, it has also proved that offline learning is irreplaceable.Key Words: online learning ,offline learning ,advantages,disadvantages.IntroductionWith the development of online and offline learning technology, two different ways of learning have emerged. During the 2019 novel corona virus (2019-nCoV) epidemic, "suspension of classes is not suspended". Online learning has become the way of learning for many students, and online education is also highly regarded. But everything has its advantages and disadvantages. At present, both online education and offline education have advantages and disadvantages.BodyⅠ. Offline learningOffline classroom is a face-to-face teaching activity between teachers and students in a fixed classroom with the help of blackboard, chalk and multimedia courseware.Most of school education is offline teaching, which has many advantages.First of all, offline teaching is still the main way of learning at present, and the teacher is a person with professional teacher qualification after special study. Therefore, both the discipline and the level of teacher's ethics are relatively guaranteed. Secondly, face-to-face teaching between teachers and students enables students to better immerse themselves in the classroom atmosphere, which is advantageous carries on the learning activity in the students, and teachers can supervise and urge students to a certain extent. Finally, teachers and students participate in the classroom together, teachers can understand students' study condition well, and adjust the teaching content and difficulty according to the students' classroom generation classroom generation, which makes teaching more flexible.However, there are also some deficiencies in offline education.First of all, the teaching location, teaching time and teachers of offline education are fixed, but each student’s learning prefer ence and learning ability are different. Maybe students will miss class because of sick leave and personal leave, or they may not adapt to or like the teacher’s teaching methods, but they do not have too many choices, which will lead to the uneven learning effect.Secondly, the learning content of offline classroom can not be selected, which is easy to produce negative psychology and frustrate their learning enthusiasm.Finally, the offline classroom is faced with student groups rather than individual students. Teachers often only explain once, or explain more common problems. If the middle school students do not understand this time, or the teacher has already mastered the content of the teacher’s explanation, then undoubtedly, for him, the learning purpose has not been achieved.Ⅱ. Online learningAs a new teaching method, online classroom has incomparable advantages compared with traditional offline classrooms. It is precisely because of these advantages that it develops rapidly and is welcomed by the majority of the audience.First of all, the learning terminal needed for online classroom is just a computer, a mobile phone or a tablet, or even a smart TV. These terminals can meet the user’s most comfortable or convenient place and time to learn through these terminals.Secondly, the online classroom of recording and broadcasting has greater flexibility in learning time. Students can study anytime and anywhere, instead of fixed time and fixed points like offline classroom learning, which makes learners have greater flexibility in learning. It can be completely free from the impact of epidemics and other major disasters, and everyone can stay at home or study anytime and anywhere.Finally, online classroom has a large number of excellent learning resources and famous teachers from all over the country. Students can learn according to their own learning needs and personal preferences. During the epidemic period, there were many free online learning channels: for example, Beijing Digital School, Learning Power, Central Video and other websites provided a large number of free learning materials. And these online courses can be repeated or intercepted to listen, which is conducive to the realization of learning objectives. With the progress of science and technology, as well as the chang e of people’s habits, online education and training will show more and more new advantages and new advantages!Although online learning has many advantages, it has not been generally satisfied with the effect of online learning during the current epidemic.First of all, some places have clocked in, turning "non-stop schooling" into "non-stop learning", and making online learning copy of offline learning with seven classes a day. Teachers, parents, especially students, are at a loss about online learning. In reality, many students do not enter the learning state and can not make good use of this valuable learning time.In addition, there are also holiday syndrome: because the work and rest time are not as regular as in school, students are easy to stay up late, work late, study inefficiently and pay no attention. When the holiday is over, students need to adapt to the school's work and rest rules and learning intensity, and schools need to take appropriate measures to help students transition.Secondly, the content of some online education and training is superficial. Although it sounds very relaxing, even entertaining and funny, it is mixed with good and bad. Most of the online training courses are fragmented learning, focusing on fragmentation, simplification, relaxation, and even entertainment and leisure, which seriously lacks systematicness and practicality.Online training, some only 15 seconds, 59 seconds, 5 minutes, 30 minutes. Of course, life class courses also have several hours long. Of course, there are also a series of chapter based training courses. However, almost all of them are fragmentary learning, which lacks systematicness and practicality. Although it sounds easy, it can not achieve the effect of systematic learning, which is far from the real effect of closed offline education and training. Most of the time, society is impetuous, especially because of the epidemic situation. When people began to develop online education and training in a rush, many people with low strength were transformed into online anchors, live teachers and even masters. However, the content lacks real value, so it is OK to listen for entertainment and superficial learning.It is believed that many people have read The Eagle Shooting Heroes. Although Guo Jing got the common guidance of the Seven Freaks of the South , his martial arts skills were always mediocre. Later, he met Hong Qigong and Zhou Botong. With a little guidance, they immediately improved their martial arts. This shows that suitable for their own online teachers can make their own learning by leaps and bounds.Finally, with the current online education and training, some teachers intellectual property rights are difficult to get effective protection. Tiktok, Kwai, NetEase, Tencent, Taobao, Baidu and so on will also find many examples of online training platforms. Copying, plagiarizing, and matching are very serious. A good content, a good idea, and a good plan will be copied by many people in a moment. Kwai, Tiktokhas seen many as like two peas in the family. A video of maggots crawling on the shaking of the year’s Eve has seen many, many identical imitations. Plagiarism in the online training industry is also very strict.Ⅲ. Will offline education and training die out?Some people will say that in what era did they even engage in offline education and learning? Now that science and technology are very developed, the Internet is developed. Online platforms are emerging endlessly, and the era of 5g is coming. Why not all online learning? This can only show that these people actually do not understand the education and training industry. Education and training pay attention to both process and result. Online education, no matter how well you speak ,is difficult to achieve the effect of offline education. If you want to really learn well, you must have offline training and teaching. Although this epidemic can be said to be a devastating blow to the offline education and training industry, online education and training can hardly replace offline education and training.Ⅳ. Combination of online and offlineBoth online and offline learning have their own advantages and disadvantages. Therefore, how to realize the mutual integration and mutual promotion of the two kinds of classroom teaching and better serve the students, learning is worth our thinking and continuous exploration. At present, the home course of multidimensional happiness curriculum developed by the school is consciously carrying out online and offline learning. In the course, both online and micro courses are explained, and students learn and explore by themselves offline. In addition, teachers timely evaluation is added to maximize the role of the course.No matter what kind of learning method or not, the purpose of existence is to provide a platform for students' learning, hoping that each student can choose his own way to lay the foundation for their own happy growth.References[1]Vincenzo Pacelli.
