Abstract Background “Freshman seminar”, as the first important learning revolution course for freshmen, originated in American colleges and universities in the middle of last century. It was not until 2003 that some research universities in China gradually launched the “freshman seminar”, which has become one of the most popular courses for the group. The course was set up late in application-oriented undergraduate colleges, and the overall teaching staff, teaching content, teaching mode and teaching evaluation are still immature and still in the exploratory stage. In particular, the emotional changes of students are not clear enough. Research design Taking the “freshman seminar” of physical education major in Nanchang Normal University as an example, this paper investigates the current situation and confusion of physical education teachers and students in Nanchang Normal University in 2019, 2020 and 2021 by means of questionnaire and interview. A total of 268 valid questionnaires were obtained. There were 6 questionnaires for teachers and 262 questionnaires for students. In order to study the impact of emotional regulation on female employees' retirement decision-making, the study adopts the Core Self-evaluation Scale. The core self-evaluation is measured by the core sel evaluation scale (CSES) compiled by judge et al. The scale consists of 10 items and adopts Likert 5-point scoring method. 1 ~ 5 points represent “very inconsistent” to “very consistent”. Previous studies have shown that the scale has good cross-cultural applicability. The internal consistency of the Core Self-evaluation Scale in this study α The coefficient is 0.824. 1.2.3 the emotional regulation self-efficacy scale adopts the emotional regulation self-efficacy scale (REEs) compiled by Caprara. Domestic research shows that the scale has high reliability and validity and is suitable for Chinese people. The scale adopts lik ⁃ ERT 5-point scoring and includes three dimensions: adjusting positive emotional efficacy, adjusting depression / pain emotional efficacy and adjusting anger / anger emotional efficacy. Emotion regulation self-efficacy scale Research results The teaching form of the freshman seminar in the Department of physical education of Nanchang Normal University is still based on the traditional theoretical lectures of administrative courses, and there is a lack of effective teaching means and methods to guide students to actively discuss. Another factor leading to the poor effect of classroom discussion is the lack of communication between teachers and students before class and students' ignorance of learning objectives. Single evaluation methods and relatively backward teaching conditions also make students lack learning motivation. Research Conclusion Based on the national undergraduate curriculum construction standards, this paper creatively puts forward the “group progressive interaction” teaching mode of “freshman seminar“ by combining the OBE education concept with the effective education theory, and constructs a curriculum teaching system with the unity of temperature, height, breadth and effectiveness. “Freshman seminar” is a teaching system with temperature, height, breadth and effectiveness. It can not only effectively improve the teaching quality of the course, but also provide some references for the “freshman seminar” of different majors in the same university. We should fully understand the important position of group discussion in group emotional factors and actively improve the group's role psychological ability. We should pay special attention to its impact on life attitude and healthy behavior, and be a healthy self-manager, coordinator and collaborator. According to the psychological characteristics of these groups, we should actively and flexibly organize colorful activities, strive to create a relaxed and harmonious living atmosphere, create a friendly and mutually beneficial emotional artificial intelligence relationship, encourage and guide these groups, adjust their psychology to the best state, and promote the healthy development of their good cognition and life.
