微课革新了传统的教学与教研模式，突破了教师传统的听评课模式，教师的电子

Micro-classes have revolutionized the traditional teaching and teaching research model, and have broken through the traditional listening and evaluation mode of teachers. The resource application of teachers’ electronic lesson preparation, classroom teaching and after-class reflection is also more targeted and effective. School-based training and regional network teaching and research will be very useful and become one of the important ways for teachers to grow professionally. Fourth, the production of micro-classes is the process of micro-research. The process by which front-line teachers find problems, analyze problems, solve problems, and make micro-classes in actual teaching is a process of teaching reflection, which can effectively promote teachers' business growth. Finally, micro-classes facilitate the dissemination of the Internet and mobile devices, facilitate the exchange of teaching experience and methods between teachers, facilitate teachers' knowledge management, and effectively promote the professional development of teachers and improve the teaching effect. <br>4. Design various types of micro-classes to raise students' interest in learning and meet students' personalized learning needs. <br>In my country's existing education model, classroom teaching is the most important form of teaching. Due to differences in learning abilities, students may not be able to master and understand all knowledge within the same time. The clear knowledge explanation and typical example analysis in the micro-class can enable students to understand the learned knowledge faster, stimulate students' interest in learning, broaden their knowledge, and promote students' systematic and cooperative learning of knowledge, and cultivate their self-learning ability. Once the content of the micro-course is determined, it is necessary to select the appropriate type of micro-course according to the teaching content. There are many types of micro-courses, including lecture type, question and answer type, heuristic type, discussion type, demonstration type, experimental type, practice type, performance type, autonomous learning type, cooperative learning type, inquiry learning type, other types and so on. Combined with the teaching content and the characteristics of students, the targeted selection should be based on the use of appropriate types of micro-classes, which can help mobilize students' learning initiative and improve the effect of micro-classes. Based on the characteristics of short, small, precise and tough micro-teaching, teachers can select topics, design, shoot and produce according to the subject teaching knowledge points or the focus, difficulties and doubts of student learning, so that the theme is prominent and the direction is clear so that students Learn the most critical content in the least amount of time

Micro-courses have innovated the traditional teaching and research model, broke through the traditional teachers' listening and evaluation mode, teachers' electronic preparation, classroom teaching and after-school reflection of the resource application is also more targeted and effective, based on the micro-course resource library of school-based research, regional network teaching and research will make a great difference, and become one of the important ways of teachers' professional growth. Fourth, the production of micro-course symbre is the process of micro-research, the first-line teachers in the actual teaching to find problems, analysis of problems, problem solving, make micro-course process, is a process of teaching reflection, can effectively promote the business growth of teachers. Finally, micro-courses are convenient for the spread of the Internet and mobile devices, facilitate the exchange of teaching experience sage and methods between teachers, facilitate teachers to carry out knowledge management, effectively promote the professional development of teachers, improve the teaching effect.<br> 4, design a variety of types of micro-classes, to raise students' interest in learning, to meet the needs of personalized learning students.<br> In our country's existing education model, classroom teaching is the most important form of teaching. Because of the differences in ability to learn from all aspects, students may not be able to master and understand all the knowledge in the same time. Clear knowledge explanation and typical case analysis in micro-courses can enable students to understand the knowledge learned more quickly, stimulate students' interest in learning, broaden their knowledge, and promote students to study systematically, study cooperatively and cultivate their own learning ability. Determining the content of micro-course stakes needs to choose the appropriate micro-course type according to the teaching content. There are many types of micro-courses, such as lecture-type, question-and-answer type, inspirational type, discussion type, presentation type, experimental type, practice type, performance type, independent learning type, cooperative learning type, inquiry learning type, other types and so on. Combined with the teaching content and the characteristics of students, targeted selection to use the appropriate type of micro-course, help to mobilize students' learning initiative, improve the effectiveness of micro-classroom. Based on the characteristics of short, small, fine and strong micro-courses, teachers can select topics, design, shoot and produce subjects according to subject teaching knowledge points or students' learning points, difficulties, and questions, so that the theme is prominent, pointing clearly, so that students can learn the most critical content with the least time.

Micro lecture innovates the traditional teaching and research mode, breaks through the traditional listening and evaluation mode of teachers, and the resource application of teachers' electronic lesson preparation, classroom teaching and after-school reflection is more targeted and effective. School based research and regional network teaching and research based on micro class resource library will have great achievements and become one of the important ways for teachers' professional development. Fourth, making micro class is the process of micro research. The process of finding problems, analyzing problems, solving problems and making micro lessons by front-line teachers in actual teaching is a process of teaching reflection, which can effectively promote teachers' business growth. Finally, the micro class is convenient for the spread of Internet and mobile devices, the exchange of teaching experience and methods between teachers, and the knowledge management of teachers, which effectively promotes the professional development of teachers and improves the teaching effect.<br>4.

Clear knowledge explanation and typical example analysis in micro class can make students understand the knowledge more quickly, stimulate their interest in learning, broaden their knowledge scope, promote students' systematic learning and cooperative learning, and cultivate their autonomous learning ability. To determine the content of micro class, we need to choose the appropriate micro class type according to the teaching content. There are many types of micro class, such as lecture, question and answer, initiation, discussion, demonstration, experiment, practice, performance, autonomous learning, cooperative learning, inquiry learning, and other types. Combined with the teaching content and the characteristics of students, the appropriate micro class type should be selected and used, which helps to mobilize students' learning initiative and improve the effect of micro class. Based on the characteristics of short, small, fine and fierce, teachers can select, design, shoot and make subject selection, design, shooting and production according to the subject teaching knowledge points or the key, difficult and doubtful points of students' learning, so as to achieve the prominent theme and clear direction, so that students can learn the most critical content in the least time<br>
