First of all, it is necessary to change and establish an educational concept different from that of ordinary senior high schools, from "managing students" to "serving students". Students should be strongly encouraged to carry out self-study according to their own work characteristics, and provide supporting services such as online answering questions, instead of being too entangled in whether he is absent from class; In the teaching arrangement, try to make the curriculum compact, instead of dogmatically and step by step implementing the teaching plan similar to full-time high schools. As long as adult students enter school, they can get a complete teaching plan for their major, and some courses can be taken in any semester, as long as they complete all courses before leaving school. The school does not arrange courses according to classes, but according to majors.

Secondly, adjust the teaching plan and increase professional courses and practical courses. The biggest difference between adult students and ordinary high school students is that their basic knowledge is far less solid than that of ordinary high school students, but their practical experience is far higher than that of ordinary high school students. It is necessary to foster strengths and avoid weaknesses, reduce the burden on students by reducing basic courses, and increase specialized courses and practical courses to improve students' professional skills. At present, some adult colleges and universities have done a good job in this respect. For example, the accounting major in a vocational school is a professional and practical course except advanced mathematics, English and computer. Adult education run by colleges and universities is generally inferior in this respect. For example, in the logistics management major of a university, there are as many as 13 basic courses, but only 10 specialized courses and 0 practical courses.

Thirdly, adjust the examination method, reduce the composition of theoretical examination and increase the proportion of practical examination. If conditions permit, we can even go further, allowing students to take the evaluation of their professional ability by their units as the results of the corresponding professional skills courses. Doing so, on the one hand, can encourage students to study with questions; On the other hand, it can help us understand the real needs of society and employers, thus promoting the construction of our related courses; At the same time, it can also strengthen our contact with employers and achieve a win-win effect among students, schools and employers.

Finally, broaden the channels of teacher selection, establish a teacher elimination system, introduce enterprise teachers and increase the proportion of case teaching. In addition to the teachers at the headquarters, we should also find ways to hire some senior executives of enterprises as teachers for adults to teach professional or vocational skills courses. Their rich work experience and lessons are a living case teaching material. Their involvement will undoubtedly enhance the teaching strength of practical teaching and increase the attraction of the course to students. The purpose of establishing teacher elimination system is to highlight the characteristics of adult education. It is necessary to invite teachers who understand the characteristics of adult education as much as possible, and to avoid teachers who are not suitable for adult education as much as possible.

Of course, there are many ways to improve the teaching quality of adult higher education in colleges and universities. This paper only talks about this problem from the experience summarized in adult teaching in recent years. From all aspects, the development of adult education has encountered certain difficulties in recent years, and the difficulties in the future may be even greater. However, we still have reason to believe the famous saying "only sunset enterprises, no sunset industry". As long as we work hard, we will do it well.
