Background: With the outbreak and spread of the COVID-19 epidemic, online teaching time has been extended continuously. The changes in teaching methods, teaching conditions, and teaching environment have brought great pressure and difficulties in adjustment to teachers, which have led to a series of physical and mental problems such as negativity, lack of confidence, and depression. The long-term accumulation of these problems makes teachers’ turnover intention increasingly serious. Methods: Based on these premises, this study took 449 high school teachers in China as research objects and investigated the relationship between high school teachers’ resilience, job burnout, and turnover intention in the context of the COVID-19 epidemic. Results: The resilience of high school teachers had a significant negative predictive effect on job burnout and turnover intention (r = −0.473, p < 0.05; r = −0.283, p < 0.05), while job burnout had a significant positive predictive effect on turnover intention (r = 0.485, p < 0.05). At the same time, job burnout played a moderating role between resilience and turnover intention (λ = −0.019, p < 0.001). Discussion: This study suggests that society, schools, families, and individuals should adopt various strategies to improve teachers’ adaptability and relieve teachers’ job burnout, so as to solve the practical problem of teachers’ high turnover intention and ensure continuous improvement and healthy development of online teaching.

Background: Considering the weakening of the economy and the shrinkage of jobs under the current global epidemic crisis, the employment of college graduates is facing unprecedented and cruel competition. However, many college students lack a reasonable understanding and orientation of themselves, which leads to them having high expectations for future careers and not considering whether they are competent or not. Due to a lack of ability and self-confidence, they appear to be at a loss and hesitant when facing career choices. Therefore, the purpose of this study is to explore the relationship between perfectionism, career adaptability and career decision-making difficulties from both positive and negative aspects. Methods: We sampled 400 college students in China and used a questionnaire to obtain cross-sectional data through the Perfectionism, Career Adaptability, and Career Decision Difficulties scales. This study explored the relationship between them using statistical analysis software such as SPSS and AMOS through the results of correlation analysis and mediating role analysis. Results: College students’ perfectionism, career adaptability, and career decision-making difficulties were significantly correlated (p < 0.01). Positive perfectionism has a negative predictive effect on career decision-making difficulties, and career adaptability plays a completely mediating role in it (the direct effect is −0.032, the mediation effect is −0.244, and the total effect is −0.276.). Negative perfectionism plays a positive predictive role in career decision-making difficulties, and career adaptability plays a part in mediating roles (the direct effect is 0.334, the mediating effect is 0.099, and the total effect is 0.433.). Conclusions: College students will more or less pursue “perfect”, but often with their own preferences to pursue, cannot be done based on the rational analysis of things to pursue perfect. College students have higher positive perfectionism and negative perfectionism, and their career adaptability is also at a higher level, but there is a higher degree of career decision-making difficulties. Positive perfectionism of college students can reduce the difficulty of career decision-making, and career adaptability plays a completely mediating role in it. Negative perfectionism of college students will lead to difficulties in career decision-making, in which career adaptability plays a mediating role.

As one of the important factors to predict future sustainable development, the difficulty of career decision-making has aroused widespread concern in psychological research. Core self-evaluation and career calling have a positive impact on college students’ career development, employees’ organizational behavior, life satisfaction, and life meaning, thus promoting individual sustainable development. Based on the Social Cognitive Career Theory (SCCT), this study mainly discusses the positive role of core self-evaluation and career calling in overcoming college students’ career decision-making difficulties, which provides support for strengthening theory and proposing educational countermeasures. This study investigates the relationship among core self-evaluation, career calling, and career decision-making difficulties for 483 Chinese college students. The results show that core self-evaluation positively predicts career calling, while core self-evaluation and career calling negatively predict career decision-making difficulties. Accordingly, career calling plays a partial mediating role between core self-evaluation and career decision-making difficulties. Therefore, college students’ career calling can be enhanced by improving their core self-evaluation, so as to further solve the difficulties in career decision-making. In the future, effective strategies should be taken to reduce the career decision-making difficulty for students’ sustainable development.

Career adaptability has attracted extensive attention from international scholars as one of the important factors predicting the future sustainability of individuals. Proactive personality and calling have a positive influence on individual career development and life satisfaction, with reference to promoting the sustainable development of individuals. This study focuses on the positive effects of career adaptability and calling on shaping female primary school pre-service teachers and provides suggestions for training excellent elementary school teachers and building quality primary education. This study investigated the relationship between proactive personality, calling, and career adaptability among 707 female pre-service elementary school teachers in Chinese universities. The results showed that proactive personality positively predicts calling and that proactive personality and calling positively predict career adaptability. Calling partially mediated the relationship between proactive personality and career adaptability. Therefore, it is possible to enhance calling by cultivating the proactive personality of female pre-service teachers in elementary schools, thus further promoting the career adaptability of this group. On this basis, effective strategies should be adopted in the future to improve the career adaptability of female pre-service teachers in elementary schools for the sustainable development of this group.

Based on the theory of sustainable development education, this paper tested the adaptability of contemporary university freshmen. Using the compilation and revision of China’s College Student Adjustment Scale (CCSAS). This paper examines five dimensions: personal emotional adaptability, learning adaptability, interpersonal adaptability, university identity, and living adaptability. Using a sample of 640 freshmen (from more than 30 universities) and considering the three dimensions of gender, major, and origin, the paper reaches the following conclusions. Generally, the adaptability of freshmen was positive and their adaptation is good; from the perspective of gender, males and females are different in physiology and psychology; from the perspective of major, there are no significant differences; from the perspective of students’ origin, there was no significant difference in general, but there were significant differences in personal emotions and university identity. Based on the above results, this paper emphasizes that to achieve the goal of sustainable development education, universities should begin to pay attention to the adaptability of students as soon as they enter the university. In addition to paying attention to the quality of teaching and learning, universities should also pay attention to the individual differences among students and the related factors that hinder their sustainable development. To ensure that students can meet the challenges of society in the future, the university should cultivate students’ awareness of sustainable development and their ability to participate in and develop sustainable practices.
