且微课的制作过于耗费时间、精力，这使得本身工作量就比较大，时间比较紧的

Moreover, the production of micro-classes takes too much time and energy, which makes the workload relatively large. It is difficult for teachers with tight time to make micro-classes autonomously and apply micro-class teaching to daily teaching work. <br>(2) The resources are not rich enough. There is no dedicated micro-class website that provides various micro-class resources and is well known to everyone. All the downloads are scattered micro-classes, and the micro-classes produced are not specifically displayed. platform. <br>(3) Accepting and applying requires a process. The use of micro-classes in teaching lacks reference experience, and the production of micro-classes needs to be continuously revised and improved in order to form a teaching strategy suitable for students. Although micro-classes have been known by more and more people, in terms of application, most of them are still in the form of, and they have not really played its value, and still need to be further promoted. <br>2. Future research ideas <br>(1) The integration of micro-class teaching with traditional class teaching needs further research and practice. How to effectively combine micro-curriculum resources and courses, and solve the temporary problems in the classroom in time, and how to make up for the shortcomings of micro-curriculum in terms of breadth, depth and complexity. The extensive use of multimedia makes classroom teaching more vivid, but how to integrate with traditional classrooms makes classroom teaching more coherent, which requires teachers to grasp this degree in time, and guide them well to avoid "deviation". Effectiveness can really cultivate students' interest in learning mathematics and inspire students' thinking

And the production of micro-course is too time-consuming, energy, which makes its own workload is relatively large, the time is relatively tight teachers are difficult to independently through the production of micro-classes, micro-class teaching applied to the daily teaching work.<br>(2) resources are not rich enough, there is no special micro-course website, provide a variety of micro-course resources, and everyone is well-known, all of you are downloading are some scattered micro-lessons, the production of micro-courses also do not have a dedicated display platform.<br>(3) Accepting and applying requires a process. The use of micro-courses in teaching lacks reference experience, the production of micro-courses needs to be constantly modified and constantly improved in order to form a teaching strategy suitable for students' situation. Although micro-lessons have been known more and more people, but in the application, most of it is still in form, did not really play its value, still need further promotion.<br> 2. Future research ideas<br> (1) The integration of micro-course teaching with traditional classroom teaching has yet to be further studied and practiced. How to combine micro-course resources with courses effectively, and solve the temporary problems in the classroom in a timely manner, and how to make up for the potential deficiencies in the breadth, depth and complexity of micro-courses. The extensive use of multimedia makes classroom teaching more vivid, but how to integrate with the traditional classroom, so that classroom teaching is more coherent, which requires teachers to grasp this degree in a timely manner, do a good job of guiding not "run-off", to make each lesson effective, in order to really cultivate students' interest in learning mathematics, to inspire students' thinking

Moreover, the production of micro class consumes too much time and energy, which makes the workload of itself relatively large. It is difficult for teachers who are tight in time to apply micro lesson teaching to daily teaching work through making micro class.<br>(2) The resources are not rich enough. There is no special micro class website to provide various micro lecture resources, which are well known to all. All the people download are scattered micro courses, and there is no special display platform for the micro lessons produced.<br>(3) It takes a process to accept and apply. The use of micro class in teaching is lack of experience for reference. The production of micro class needs to be constantly modified and improved to form teaching strategies suitable for students' situation. Although the micro class has been known by more and more people, but in the application, most of it is still a mere formality, and it does not really play its value, so it still needs further promotion.<br>2.

How to effectively combine the micro class resources with the curriculum, and timely solve the temporary problems in the classroom, and how to make up for the possible deficiencies in the breadth, depth and complexity of the micro class. The extensive use of multimedia makes classroom teaching more vivid. However, how to integrate with traditional classroom teaching to make classroom teaching more coherent requires teachers to grasp this degree in time, do a good job in guiding and not "deviate", and make every class effective, so as to cultivate students' interest in learning mathematics and inspire students' thinking
