changing. Meanwhile, in the era of "Internet+", it has already become a unavoidable issue in the current background of the time that how teachers in ethnic areas can effectively use new technologies to cope with the challenges of the "Internet+" era, so that the technologies and concept of the "Internet+" era can better help them achieve professional development. At the same time, this issue also is of great significance because it bears on the quality of education in ethnic areas in the future. This study surveys the professional development of teachers in a certain ethnic minority county, aiming to better study the influence and strategies of teachers in the professional development under the background of "Internet+", so as to provide better theoretical support for the research of the academic and educational circles on the professional development of teachers in the region.

Changes in the Roles and Functions of Teachers in the Era of "Internet+"
In the era of "Internet+", the functions that teachers should have are no longer limited to teaching, but tend to be diversified and varied. Teaching also evolves from teaching in front of stage to teaching in front of screen.

The Functions of Teachers Are Increasingly Diversified
In the "Internet+" era, the authority of teachers' roles gradually diminishes, teacher's functions are diversified, and teachers are no longer the traditional people standing on the podium. The changes in these functions are mainly reflected in: 1) the innovator of education and teaching; 2) the leaders, helpers, and organizers of students' learning; 3) the promoters of the development of students' thinking ability; 4) the builders and leaders of the harmonious relationship between teachers and students. At the same time, in the "Internet+" era, teachers must also learn to use the resources and materials on the Internet to enrich the teaching design and improve the quality of teaching [1].

The Roles of Teachers Shift from Teaching in Front of Stage to Teaching in Front of Screen
Traditionally, teachers took the three-foot podium to impart knowledge. However, in the "Internet+" era, teachers go from in front of stages to in front of computer screens. Compared with the students in the past, the new generation of students influenced by the Internet has desired wider and deeper knowledge, which also makes it difficult for many teachers to fully satisfy the students' needs with their current knowledge reserve. For teachers, how to make better use of the resources of the "Internet+" era and achieve professional development to better meet the knowledge needs of students in front of computer screens is a question that calls for consideration.

The Analysis of the Opportunities and Challenges Faced by Teachers in the "Internet+" Era
Based on the previous analysis, we can find that in the "Internet+" era, the functions and roles of teachers have changed, and new demands have been put forward for the professional development of teachers. For teachers, in the era of "Internet+", to achieve their own professional development, they must fully recognize the current opportunities and challenges:

Analysis of Opportunities
The advancement of information and technologies in the era of "Internet+" has provided tremendous opportunities for the professional development of teachers. This is reflected in the following aspects: 1) The sharing of information provides rich resources for teachers' professional development.
In the past, teachers can only seek out-of-school education to improve their own professional quality. In the era of "Internet+", teachers are enabled to break the traditional limitations set by distance. They can obtain new professional knowledge just by connecting to the network and learning on various educational websites or educational platforms. At the same time, on the Internet, teachers can also learn and refer to the classroom teaching methods of other excellent teachers, and have interactions with their peers, which provides resources and methods for the professional development of teachers [2].
2) Network technologies enhance the efficiency of teacher professional development.
In the era of "Internet+", the widespread use of various information technologies has help teachers overcome the limitations of time and space for teacher education and teaching. In the past, teachers can only obtain professional knowledge in certain places to realize professional development. Some knowledge must also be acquired in a certain period of time. In the "Internet+" era, teachers only need a smart phone or tablet to acquire professional knowledge at any time, which greatly enhances the efficiency of teacher professional development.
3) Teacher-student interactions make teachers' professional development more efficient.
The "Internet+" era has also greatly facilitated the interaction between students and teachers [3]. Teachers can not only interact with students in classrooms, but also use various social media in the "Internet+" era to carry out interactions with students after class, so as to get to know the weak points of students' learning and the areas where their teaching needs to be improved. In this way can their professional development be more efficient.

Analysis of Challenges
Although the technologies of the "Internet+" era provide great convenience for the professional development of teachers, they may also cause confusions among teachers about professional development if they rely too much on information and technologies. Specifically, the "Internet+" era has brought the following challenges to the professional development of teachers: 1) The sharing of resource may cause teachers to lose their teaching personalities.
In the context of resource sharing in the "Internet+" era, teachers can not only refer to the cases shared by excellent teachers, but also share their own teaching plans and coursewares [4]. However, one of the negative effects of resource sharing is that it may lead to homogenization among teachers. After resources are shared, teachers in different places and at all levels may cite these resources without giving them any modification, thus causing the loss of personalities and creativity of teachers.
2) There is a lack of consideration for the effectiveness of Internet education resources and technologies.
With the arrival of the "Internet+" era, it has become the choice of teachers to use various Internet technologies to enrich the characteristics of teaching and follow trends of the time [5]. However, some teachers deliberately use Internet education resources and information technologies while ignoring the appropriateness of the use of these resources and technologies. They do not fully consider whether the use of technologies can truly enhance their professional abilities and improve the quality of teaching.

Survey on the Professional Development of Teachers in Ethnic Areas in the Era of "Internet+"
Under the background of "Internet+", this study conducted a questionnaire Therefore, the effective sample rate of this survey is 95.51%.

Questionnaire Design
Based on the previous analysis, in the "Internet+" era, the roles and functions of teachers have changed. At the same time, the "Internet+" era has also brought opportunities and challenges to the professional development of teachers. The Likert scale was introduced into questionnaires when designing answers to all questions. Each answer has five options, namely "completely disagree", "disagree", "neutral opinion", "agree", "completely agree", which corresponds to 1 -5 points respectively. Then, the questionnaire results were calculated by finding out the average value of each question.

Analysis of the Survey Results
According to the collected statistics of the first part of the questions-1) You are aware that the functions of teachers are increasingly diversified, and 2) During daily teaching, you often use Internet media and new media to communicate with students besides teaching in front of stage, the scores are 4.124 and 4.232 respectively, which is located between "agree" and "completely agree". This demonstrates that teachers in ethnic areas can fully realize the transformation of teachers' roles and functions in the era of "Internet+".

Strategies for the Professional Development of Teachers in Ethnic Areas in the Era of "Internet+"
Under nologies. Based on these findings, this paper puts forward the following strategies for the professional development of teachers in ethnic areas in the "Inter-net+" era.

Use Interactive Teaching to Promote Professional Development
According to the previous survey, we know that teachers in this ethnic area do not pay attention to using the Internet to interact with students, which is also commonly seen in other ethnic areas. This is because many ethnic areas are mostly located in economically underdeveloped areas, and ethnic minority students may use Internet devices less frequently and and can only find less diverse resources compared with their counterparts in economically developed areas.
However, with the arrival of the information age, it can be forecast that students from ethnic areas will have access to more Internet devices for learning in the future, which lays a material foundation for the online interaction between teachers and students. Therefore, the author suggests that teachers in ethnic areas should take advantage of the opportunities brought by the "Internet+" era, make full use of interactive teaching to communicate with students effectively and thus learn about their learning situation, as well as students' evaluation of their own teachings. With these efforts, teachers can find flaws in their current teaching and make corresponding improvements to enhance their professional teaching level [6].

Use Online Platforms to Promote Professional Development
According to the previous survey, teachers in ethnic areas have not fully utilized the online platform to share experiences with other teachers on the internet, and they also make less use of online platforms to receive continuing education.
Therefore, the author suggests that teachers in ethnic areas should use various online platforms to help promote their professional development, and also real-

Cultivate the Subject Consciousness of Professional Development and Construct Teaching Content with More Local and Ethnic Characteristics
According to the previous survey, the sharing of education resources in the era of "Internet+" is causing teachers to lose their own teaching personalities. Subject consciousness is the core of teachers' professional development, and also the key to highlighting the professionalization of teachers. In the context of "Inter-net+", teachers in ethnic areas should pay attention to constructing the subject consciousness of their own professional development. For instance, when learning and drawing on the teaching experience and teaching methods of excellent teachers in developed regions, teachers in ethnic areas can make corresponding adjustments in light of the reality of minority students, and construct teaching content with more local and ethnic characteristics. The unique culture of ethnic areas can be incorporated into their own teaching, thus enriching the characteristics of their own teaching.

Reflect on and Improve the Use of Information Technologies and Online Education Resources
According to the previous survey, teachers in ethnic areas often deliberately use information technologies and online education resources. Meanwhile, teachers are facing such challenge as how to choose appropriate ones from the excessive education resources on the Internet. Faced with this problem, the author believes that teachers in ethnic areas should integrate what they have learned with real practice, put their knowledge into flexible use and make regular reflection and improvement in the process of professional development with the help of information technologies and online education resources. In practice, reflection and improvement are also essential strategies for the professional development of teachers. In the era of "Internet+", teachers in ethnic areas must first consider whether the use of information technologies can truly improve the quality of teaching and achieve the goal of teaching, rather than blindly follow suit and use various information technologies and online education resources. At the same time, teachers in ethnic areas should also reflect on and evaluate the effect of the use of information technologies and constantly revise the used methods, so as to give full play to the role of information technologies and promote the sustainable development of their professional quality.

Conclusion
In summary, with the arrival of the "Internet+" era, the roles and functions of teachers are constantly changing, and the technologies and resources of the "In-ternet+" era also bring opportunities and challenges to the professional devel-
