Teaching satisfaction and resilience play important roles in the education field, but most research focuses on higher education, with few scholars studying their impact on language teaching within the context of middle school education. In this sense, this study employs a mixed-methods research design, selecting 375 Chinese middle school English teachers to investigate the roles of teaching satisfaction and resilience in the relationship between self-efficacy and teachers’ well-being. A structural equation modeling approach and NVivo were utilized to analyze quantitative data and qualitative data, respectively. Quantitative results reveal that both teaching satisfaction and resilience mediate the relationship between self-efficacy and teachers’ well-being. Qualitative interviews reveal that teaching satisfaction primarily enhances job commitment, reduces job stress, improves student relationships, and increases professional growth. Meanwhile, resilience plays a crucial role in stress management, positive adaptation, and emotional regulation. This research offers insightful implications for improving teachers’ well-being and contributes significantly to the broader discourse on foreign language teacher education.

UN’s 2030 Agenda for Sustainable Development highlights the crucial role of education in securing a promising future for humanity, especially in today’s digital era. However, the prevalence of smartphones has fostered an increase in students’ usage and subsequent digital multitasking tendencies, posing a significant threat to education process, especially in higher education. To gain further insights into this phenomenon, this exploratory descriptive study surveyed 519 students from China university to investigate the magnitude of students’ digital multitasking, motivation behind digital multitasking, and beliefs about reducing phone use. The study found that, (1) despite many respondents reporting the existence of phone limits, no possible reduction in phone use frequency was observed; (2) digital multitasking was positively correlated with mobile phone dependence and non-study motivation; (3) while a majority (86.71%) students expressed their intent to reduce digital multitasking, they were mostly hesitant to follow the moderate or strict rules on phone use; (4) no clear consensus was established (49.90% vs. 50.10%) regarding whether schools should pose more restrictions to encourage such reduction. Our research provides further insights into students’ digital multitasking to improve learning quality and sustainable education.
