As an important part of the national higher education system， in the context of higher education incentives， public security education and training， and their own continuous development and competition， how to rely on advantages and characteristics to deepen education and teaching reform constantly improving the quality of personnel training and further meeting the actual needs of public security work and public security team building is an issue of the times that public security higher education workers must face， think and solve. At this stage， with the rapid development of micro-blog， weChat， micro-video， and client-side “three micro-ends”， how to make good use of “three micro-ends” to form a unified interactive platform to improve the quality of education and teaching in public security colleges， and to ensure the reform of education and education. An important development path combining public security education reform with scientific and technological information technology。

1. The necessity of education and teaching reform in public education

1.1 The reform of education and teaching is a realistic task of persisting in the field of higher education and constantly grasping new things

The reform of education and teaching has always been an important proposition in the field of higher education. Especially since the beginning of this century， the call for deepening the reform of education and teaching has become increasingly fierce. The outline of the national medium and long-term education reform and development plan （2010-2020） points out that higher education should “adapt to the needs of national and social development， follow the laws of education and the law of talent growth， deepen education and teaching reform， innovate education and teaching methods， and explore more. A variety of training methods have formed a situation in which all kinds of talents are emerging and top-notch innovative talents are constantly emerging.” Along with the introduction of a series of national documents such as the “ministry of education's several opinions on improving the quality of higher education”， the “educational teaching reform” was promoted to a prominent position， and a new round of nationwide reform of higher education teaching began.

1.2 Education and teaching reform is an important starting point for the continuous improvement and development of public security education and training in the new era

After several decades of development， the public security education and training work has formed an operational system with stable scale， distinctive features and diverse levels. However， there are still deficiencies and shortcomings in structural layout， resource allocation， quality construction， and method innovation. The “guiding opinions of the ministry of public security on strengthening the construction of public education and training bases” fully emphasizes the importance and role of education and teaching reforms in public security education and training， and regards education and teaching reform as an important work in the field of public security education and training in the future. Education and teaching reform has become an inevitable choice and an important starting point for solving outstanding problems and contradictions in the field of public security education in the new era.

2. Preliminary practice exploration of bilingual teaching reform in public education based on the unified platform of “three micro ends”

“Three micro-ends” is gradually developed along with the development of smart phones. According to CCTV news reports， as of September 30， 2017， the number of monthly active users of micro-blog has reached 323 million； the number of monthly active users of WeChat has reached 756 million. Number of people； users cover more than 180 countries. It can be seen that almost all college students are using the “three micro-ends”. Therefore， we can consider building a “three micro-ends” unified platform， relying on the unified platform for all-round and timely. We take the bilingual flipping classroom and the “three micro-ends” unified platform to improve the quality of teaching reform as an example， and carry out preliminary practical exploration.

2.1 Bilingual flip classroom teaching based on the “three micro ends” unified platform can effectively improve classroom efficiency

The bilingual flipping classroom teaching process based on the “three micro end” unified platform mainly includes three stages of learning before， during and after class. Using the unified platform built， the teacher needs to arrange the preparatory work for the students during the pre-class study period. To this end， teachers should issue a learning task list to enable students to clarify the content of self-study. During the learning phase of the class， teachers no longer teach basic knowledge， but communicate with students about the key points and difficulties of the course. In the after-school learning stage， teachers will also arrange learning task lists for students through a unified platform to help students deepen their understanding of the knowledge they have learned and further expand.

2.2 Bilingual flipping classroom based on the unified platform of “three micro ends” is a model of modern science and technology and education

Bilingual flipping classroom effectively combines internet and computer technology with bilingual teaching， making itself feasible and realistic. Among them， the application of modern information technology such as cloud computing is an important means and resource for the realization of bilingual flipping classroom based on the unified platform of “three micro ends”. The important support of the bilingual flipping classroom is the technical support of applying the “three micro ends” to the cloud platform. A very important feature of the bilingual flip classroom is the application of micro video for teaching. Teaching micro video is often referred to as micro-class， and its biggest feature is short and fine. The teacher realizes the recording of the teaching micro video， edits it and publishes it on the cloud platform for students to watch. Each video is targeted at a specific issue and is highly targeted. Moreover， the length of the video is controlled within the time range in which the students’ attention can be concentrated， which is in line with the physical and mental development characteristics of the students； the video released through the network has various functions such as pause， playback， etc.， and can be self-controlled， which is beneficial to the independent learning of the students.

2.3 Bilingual flipping classroom based on the unified platform of “three micro ends” pays attention to the initiative of students

The bilingual flipping classroom based on the unified platform of “three micro ends” changed the proportion of teachers and students’ main characters in classroom teaching， reconstructed the learning process of students， and highlighted the status of students in the design of teaching links. First of all， students can use high-quality educational resources through the Internet before class， and no longer rely solely on the instructor to teach knowledge. Second， the roles of students and teachers in the classroom have changed. Students use the group learning mode to conduct exploratory learning of knowledge. The mutual communication between students helps to promote the internalization process of students’ knowledge. Teachers only use part of the time to explain key and difficult knowledge， and teachers are more responsible for understanding students’ problems and guiding students to use knowledge. In addition， the traditional classroom teaching mode is mainly led by teachers， but because each student’s ability is different， the learning effect between individuals is different. In the bilingual flipping classroom mode， teachers can judge the difference of their abilities and the learning difficulties of students through the answering situation of the students’ pre-study stage， so as to carry out differentiated guidance and training.

3. Conclusion

In summary， the reform of education and teaching is the theme of the era of public security education and training. Therefore， the unified platform of “three micro-ends” can be used as a guarantee for bilingual teaching. This kind of reform is also a realistic task of public security colleges and universities. Facing， thinking and solving together， we will promote the development of public security higher education in a better and faster way.
