This study was conducted in accordance with recognized ethical guidelines for social science research. Prior to commencement, the research protocol, including the informed consent forms, survey instrument, and interview questions, was reviewed. All participants were provided with a detailed information sheet outlining the study's purpose, the voluntary nature of their participation, their right to withdraw at any time without penalty, and the measures in place to ensure anonymity and confidentiality. Written informed consent was obtained from every participant before data collection began.
Ensuring the best ethical standards possible was the priority in this study. The rule of anonymity was followed; all data were anonymized at the transcription and analysis stages, and any point of identification included was eliminated. Pseudonyms refer to participants in this manuscript. To address confidentiality, all digital data was stored on a password-protected secure server. In contrast, physical records were stored in a locked cabinet to which only the primary researchers had access. The interview was conducted in a confidential setting where the participants felt comfortable and were free to express their opinions. Moreover, the researchers also took the stance of reflexivity, whereby their views were also taken into consideration, and the voices and experiences of the respondents were depicted without bias or compromise of their viewpoints.
Research design
To achieve a comprehensive understanding of the research problem, this study employed a sequential mixed-methods research design. This approach integrates quantitative and qualitative data collection and analysis within a single study to provide a more complete and nuanced analysis than either method could alone21. The quantitative phase involved a cross-sectional survey to gather broad, generalizable data on the prevalence and nature of job-crafting dilemmas among physical education teachers. This was followed by a qualitative phase consisting of in-depth, semi-structured interviews. The purpose of this second phase was to elaborate, clarify, and contextualise the statistical findings, exploring the underlying reasons and personal experiences behind the quantitative trends. The combination of these methods allowed for triangulation, where the convergence of findings from different data sources strengthens the validity and depth of the conclusions.
Population and sampling
The target population for this study was in-service physical education (PE) teachers in secondary schools and universities within the Zhejiang province of China, who are involved in or exposed to initiatives in intelligent physical education. A sequential mixed-methods sampling strategy was employed. For the quantitative phase, a stratified random sampling technique was used to enhance representativeness. The sampling frame was constructed by first identifying major urban and suburban school districts within Zhejiang, as well as universities with physical education programs. Schools were then randomly selected from these lists. Within each selected institution, PE teachers were invited to participate. This approach ensured a broad and varied cross-section of the provincial teaching workforce. A total of 150 questionnaires were distributed, yielding 126 valid responses, resulting in a high response rate of 84% (Table 1). The demographic profile (presented in Table 2) reflects a sample with varied experience; notably, the largest group (41.3%) had 6-10 years of teaching experience. The sample was predominantly male (72.2%), reflecting a gender distribution common in the field within the region. It is essential to clarify that the reported proportion of respondents holding doctoral degrees (20.8%) pertains specifically to the university-level instructors and senior academic staff within the sample, which included faculty from teacher training programs at institutions such as Zhejiang Normal University and Hangzhou Normal University. This is not representative of frontline schoolteachers, among whom such qualifications are less common. For the subsequent qualitative phase, a purposive sampling strategy was used to select information-rich cases from the survey respondents who agreed to further contact. Five PE teachers were selected to ensure maximum variation in gender, teaching experience, and institutional level (secondary vs. higher education) (Table 3). This strategic selection aimed to capture diverse perspectives, from early-career schoolteachers adapting to new technologies to experienced university educators navigating role transformation22.
Data collection procedure
First, quantitative data were gathered using a self-designed questionnaire titled "Survey on the Influence of Artificial Intelligence on Job Crafting of Physical Education Teachers." Before widespread distribution, the instrument was piloted with 36 teachers (not included in the main study) to assess clarity, reliability, and validity. The finalized questionnaire was then administered to the stratified random sample of 150 teachers. The survey was designed to measure key dimensions of job-crafting dilemmas cognitive, task-related, and relational, within the context of intelligent sports education. Following the preliminary analysis of the survey data, the second, qualitative stage was initiated. Following the quantitative analysis, the second stage involved in-depth, semi-structured interviews designed to explore and contextualize the specific job-crafting dilemmas identified in the survey. The primary researcher, who had no prior relationship with any participants, contacted five respondents from the survey sample who had consented to follow-up contact. Initial contact was made via the official email or institutional communication channel provided during the survey, extending a formal invitation that reiterated the study's purpose and ethical assurances.
All interviews were conducted formally, following a predesigned protocol. They were held in a private, neutral setting such as a reserved meeting room at the participant's institution to ensure confidentiality and comfort. The interviews were conducted in Mandarin Chinese, the participants' native language. Each session lasted between 45 and 70 min, with an average duration of approximately 55 min. The conversations were guided by an open-ended question schedule but allowed for flexibility to probe emerging themes. All interviews were audio-recorded using a dedicated digital recorder, with the participant's written consent obtained again at the start of each session. No video recording was used to minimize participant discomfort. To ensure accuracy, the audio files were transcribed verbatim in Mandarin by the researcher shortly after each interview. The transcribed texts were then thematically analyzed, with key illustrative quotes selected for the final manuscript. These quotes were translated into English by the research team, employing a back-translation check with a bilingual expert to verify semantic equivalence.
Data analysis methods
The collected data were analyzed using specialized software to ensure rigor (see Figure 1). The quantitative data from the 126 valid questionnaires were imported into statistical analysis software. Descriptive statistics (frequencies, percentages, means, and standard deviations) were calculated to summarize the demographic characteristics and the general trends in the responses. Reliability analysis (Cronbach's Alpha) was conducted on the scales to confirm internal consistency, and inferential analyses were likely performed to examine relationships between variables. The qualitative data from the interview transcripts were analyzed to facilitate a structured and systematic thematic analysis. This process involved repeatedly reading the transcripts to achieve familiarity, generating initial codes, and then collating these codes into potential themes. The themes were then reviewed, refined, and defined to ensure they accurately represented the data collected. This inductive process allowed the core dilemmas, cognitive, task-based, and relational, to emerge directly from the participants' narratives, providing rich, qualitative evidence to support and explain the quantitative findings23.
