　Comparative analysis bet365 champions league context of visualization

In order to ensure the scientificity and objectivity of comparative research，Correctly reflects the context and overall situation of the development of bet365 champions league classrooms in China and the United States，We selected two databases that are authoritative and popular in both Chinese and American academic circles for comparative research，They are the Chinese Social Science Citation Database (CSSCI) and the Web of Science (WOS) core collection database。

First，Analysis from the perspective of the number of papers related to flipped bet365 champions league published annually。Documents retrieved from two databases，Utilize visual analysis tools，Obtained the data on the number of publications related to flipped bet365 champions league in China and the United States from 2012 to 2019，And plotted into a chart (Figure 1)。Data display，China’s overall publication volume is not stable in the statistical year，Showing a trend of first growth and then decline。Starting from 1 article in 2012，Reach the annual peak of 199 articles by 2015，Then it decreased year by year。The number of articles published in the United States is increasing year by year。1 article from 2012，Grown to 274 articles in 2019。Can be found by comparing data，The total number of papers on flipped bet365 champions league is more than 200 in the United States than in China，There was a research boom in China，Research in related fields in the United States maintains a certain degree of persistence and growth。

Secondly，Analysis from the perspective of flipped bet365 champions league research related subject distribution。As can be seen from Figure 2，2012-2019，The subject distribution of papers on flipped bet365 champions league in China mainly involves education、Language、Library, information and archives and other disciplines，Among them, the education discipline ranks first with 752 articles，Accounting for 89 of the total number of posts.2%；The second place is language subject，The number of articles published is 45，Proportion 5.3%。The combined proportion of these two disciplines is almost 95%，There are very few publications involving other disciplines。As can be seen from Figure 3，The subject distribution of papers on flipped bet365 champions league in the United States is relatively balanced，Mainly focused on education and teaching research、Educational Science、Chemistry Multidisciplinary、Health care science、Computer science and other disciplines。The number one ranking is education and teaching research，The number of articles published is 429，Accounting for 37 of the total number of posts.9%；The second place is the subject of Educational Science，The number of articles published is 305，Accounting for 27%。Comparison picture 2、Can be found in Figure 3，The distribution of disciplines in China is mainly concentrated in the discipline of education，The research content is mostly at the theoretical level；American disciplines present a multi-disciplinary distribution status，Mainly distributed in applied practical disciplines。

AGAIN，Analysis of institutions conducting flipped bet365 champions league research in China and the United States。As can be seen from Table 1，Research in related fields in China is mainly concentrated at East China Normal University、Beijing Normal University、Shaanxi Normal University、Central China Normal University and Peking University；The United States is mainly concentrated in Harvard University、University of California、University of North Carolina、University of Florida and the Commonwealth of Pennsylvania System of Higher Education。The research institutions with the largest number of publications in China and the United States are East China Normal University (31 articles) and Harvard University (30 articles) respectively。But the obvious difference between China and the United States is，China’s research institutions are mostly concentrated in normal colleges and universities，In the United States, most of them are concentrated in comprehensive universities，This also supports the discipline distribution rules summarized above。China mainly carries out research on flipped bet365 champions league in the field of teaching subjects，Therefore，Research institutions are mostly normal universities；The United States conducts more research in the field of practical applications，Therefore, most research institutions are comprehensive universities。

Finally，Analyze the differences in teaching models between China and the United States。The American flipped bet365 champions league teaching model is student-centered，Emphasis on communication and interaction between teachers and students and between students，Students are the protagonists of the bet365 champions league。Students can consider their own characteristics and knowledge differences before class，Flexible、Learn professional knowledge freely，You can discuss projects and goals in class、Communication。my country’s flipped bet365 champions league teaching capacity is large、High requirements，The teaching model is mainly teacher-centered，Pay attention to basic knowledge in teaching，Emphasis on students’ acceptance and mastery of basic knowledge。

　　Analysis and Suggestions on bet365 champions league Prospects

In terms of development strategy，We should shift from simple imitation to focusing on localization。Discoverable through existing measurement data and visual analysis，Research on flipped bet365 champions league in China mainly focuses on the field of education，Mostly flipped bet365 champions league model、Development Trend、Theoretical introduction and research on American cases and other aspects，However, there are relatively few localization studies based on the national conditions of education in my country。Flipped bet365 champions league originated in the United States，To use it more effectively in our country，Make it an effective starting point to promote the reform of teaching methods in our country，We must take the localized development path，Based on actual national conditions，Find a development method that suits you。

On development goals，Should shift from subject exploration to domain sharing。It can be found from the comparison of the previous data，The subjects that use the flipped bet365 champions league model in the United States are relatively widely distributed，This is similar to the early start of flipped bet365 champions league in the United States、The research is relatively mature。The distribution of disciplines using the flipped bet365 champions league model in my country is mainly concentrated within education。Therefore, we should consider which fields in China are suitable for adopting the flipped bet365 champions league model，How to transfer the flipped bet365 champions league model to other subjects。

In the direction of development，Should shift from theoretical discussion to practical application。The essence of flipped bet365 champions league is to mobilize students’ subjective initiative、Combined before and after class、Teaching methods to improve students’ learning efficiency and creativity。It stems from practical dilemma，Improving through practical exploration，Deepen in practice and promotion。Only in specific practical applications，In order to know the specific operation method，Get first-hand teaching experience，To better apply it in future teaching。Therefore，Our country’s flipped bet365 champions league should be based on practice、Development orientation into practice，Realize from model construction to practical application、Transition from a single subject area to a multi-disciplinary area。

In terms of development ideas，Should shift from teacher-centered to student-centered。Development goals from flipped bet365 champions league、Look at specific applications and practical exploration，The main direction is to promote the transformation of teachers' role from "protagonist" to "director"。To realize the transformation from teacher-centered to student-centered teaching model，Need to cultivate two consciousnesses。First, cultivate teachers’ sense of service in the teaching process；The second is to cultivate students’ awareness of self-control。Let students continuously deepen their awareness of active learning during the learning process，Through self-management of the learning process，Develop self-management、Active exploration、The ability to actively build a knowledge system。

On the development concept，We should shift from traditional teaching to actively learn from international advanced experience。The difference in educational concepts between China and the United States is mainly reflected in whether they value universal education or individualized education。From the successful experience of American teaching practice，Studying before and after class is equally important as learning in the bet365 champions league。Therefore，We should break through the traditional single bet365 champions league teaching concept，Change to the advanced teaching concept of "before class + during class + after class" trinity。
