At present, the first batch of “Post-00s” publicly-funded oriented students has been in the teaching position for nearly a year, and new teachers will face many pressures and challenges in the early stage of employment. In order to gain an in-depth understanding of the current situation of the career adaptation of the “Post-00s” publicly-funded oriented students, this study selected three newly recruited “Post-00s” publicly-funded directional students as the research objects, and conducted in-depth interviews with three representative “Post-00s” publicly-funded directional students in H City from four aspects: vocational motivation, career satisfaction, occupational pressure and career help, analyzed the occupational adaptation problems and influencing factors of the “Post-00s” newly recruited teachers, and concluded that the i展开更多
