(1) pertinence and effectiveness. Adult education and teaching is based on the different needs of different objects, production and work-oriented, effective service and strong pertinence. At the same time, the object of adult education and teaching is adults who have already taken part in work or entered social life. They pay more attention to their work and life, and pursue self-realization and self-improvement more urgently, which determines the effectiveness of their learning and seeking advice, that is, only those knowledge that is useful to them are willing to seek advice, and those almost empty sermons will not arouse their much interest. (2) Practicality and applicability. The content of adult education teaching is mostly technical knowledge or operational knowledge, and the teaching of theoretical knowledge also serves the purpose of application. Therefore, in the teaching process, if we can strengthen the practice link and combine theory with practice for teaching and demonstration, we can often have better results. The best way is to guide students to do it themselves, apply the knowledge and skills they have learned to actual production or work, and cultivate students' ability to use and solve problems flexibly. (3) Autonomy and cooperation. In adult education and teaching, students' initiative is more prominent, because for them, life experience and work experience are relatively rich, world outlook and outlook on life have become stable, and they have independent consciousness and initiative. In teaching, teachers should pay attention to highly respecting students, arouse students' autonomy in learning, and cooperate effectively in teaching to ensure teaching quality and efficiency. (4) Short-term quick effect. Adult education and teaching can be completed in a short time, so that adults can learn and master certain knowledge and skills after work or during breaks, without going through a long period like ordinary schools. At the same time, after adults engage in learning, accepting knowledge and forming skills, their benefits can be reflected in a short time and achieve the expected results.
