The paper presents the most comprehensive and large-scale global study to date on how higher education students perceived the use of ChatGPT in early 2024. With a sample of 23,218 students from 109 countries and territories, the study reveals that students primarily used ChatGPT for brainstorming, summarizing texts, and finding research articles, with a few using it for professional and creative writing. They found it useful for simplifying complex information and summarizing content, but less reliable for providing information and supporting classroom learning, though some considered its information clearer than that from peers and teachers. Moreover, students agreed on the need for AI regulations at all levels due to concerns about ChatGPT promoting cheating, plagiarism, and social isolation. However, they believed ChatGPT could potentially enhance their access to knowledge and improve their learning experience, study efficiency, and chances of achieving good grades. While ChatGPT was perceived as effective in potentially improving AI literacy, digital communication, and content creation skills, it was less useful for interpersonal communication, decision-making, numeracy, native language proficiency, and the development of critical thinking skills. Students also felt that ChatGPT would boost demand for AI-related skills and facilitate remote work without significantly impacting unemployment. Emotionally, students mostly felt positive using ChatGPT, with curiosity and calmness being the most common emotions. Further examinations reveal variations in students’ perceptions across different socio-demographic and geographic factors, with key factors influencing students’ use of ChatGPT also being identified. Higher education institutions’ managers and teachers may benefit from these findings while formulating the curricula and instructions/regulations for ChatGPT use, as well as when designing the teaching methods and assessment tools. Moreover, policymakers may also consider the findings when formulating strategies for secondary and higher education system development, especially in light of changing labor market needs and related digital skills development.

Grounded in self-determination theory (SDT), the present study tested how students’ perceptions of autonomy support from physical education teachers predicts objectively measured moderate-to-vigorous physical activity (MVPA) of adolescents. According to SDT, it was expected that psychological needs and autonomous and controlled forms of motivation would mediate these relationships. Students (n = 397) aged from 11 to 15 years in 17 different schools filled in questionnaires regarding SDT variables. In addition, objective MVPA was measured using an accelerometer (ActiGraph GT3X; ActiGraph, Pensacola, FL, USA) for 7 days. Structural equation modelling was used to examine the hypothesized relationships among the study variables. The theory-based model showed a good fit with the data: χ2 = 642.464, df = 257; comparative fit index = 0.932; non-normed fit index = 0.921; root mean square error of approximation = 0.062; root mean square error of approximation 90% confidence interval: 0.054–0.067. As hypothesized, there was a significant and positive direct relationship between autonomy support and need satisfaction (β = 0.81, p = 0.001). In turn, need satisfaction positively predicted intrinsic motivation (β = 0.86, p = 0.001). Intrinsic motivation was positively related to MVPA (β = 0.29, p = 0.009). A significant indirect effect (β = 0.20, p = 0.004) supported the mediating role of psychological need satisfaction and intrinsic motivation in the relationship between perceived autonomy support and objectively measured MVPA. The findings of the current study support the applicability of the SDT-based model in explaining the antecedents of objectively measured MVPA of adolescents. To enhance adolescents’ daily MVPA, special focus should be put on increasing their intrinsic motivation toward physical education.

Students’ health-related quality of life (HRQoL) may depend on the extent to which the school environment fostered by their teacher is perceived as autonomy-supportive. We tested a conditional process model in a physical education context in which students’ perception of their teachers’ autonomy-supportive behaviour moderated the relationship between perceived controlling behaviour and HRQoL via need frustration. School students (N = 1042) completed self-report measures of perceived teachers’ autonomy support, perceived controlling behaviour, need frustration, and HRQoL. As predicted, the effect of perceived teachers’ controlling behaviour on HRQoL was mediated by need frustration. Perceived autonomy support did not moderate this indirect effect. Specifically, higher levels of autonomy support did not attenuate the indirect effect of perceived controlling behaviour on HRQoL through need frustration. Findings highlight the importance of minimizing controlling behaviour, rather than an exclusive focus on enhancing autonomy-supportive behaviour, to enhance students’ HRQoL.

The current research adopts the trans-contextual model of motivation (TCM) to examine the role of perceived autonomy support from peers, parents, and physical education (PE) teachers on adolescents’ autonomous motivation, intentions, and physical activity (PA) and health-related quality of life (HRQoL) over a one-year period. Adolescents (N = 264) aged between 11 and 15 years (M = 13.24; SD = 0.96) filled in relevant questionnaires during a four-wave longitudinal study. Perceived autonomy support from peers, parents, and PE teachers predicted PA (β ≥ 0.03, p < 0.009) and HRQoL (β ≥ 0.01, p < 0.009) mediated by constructs of TCM over a one-year period. The regressions of PA (β = 0.45, p < 0.001) and HRQoL (β = 0.56, p < 0.001) on themselves over a one-year period were significant. PA significantly predicted the HRQoL measured one year later (β = 0.20, p < 0.001), but not vice versa (β = 0.04, p = 0.52). The unidirectional cross-lagged relationship with the flow from PA to later HRQoL suggests that intervention programs focusing on promoting PA behaviour in adolescents should produce the most pronounced effects if their aim is also to promote HRQoL.

This research aimed to develop and validate an instrument to assess the students’ perceptions of the teachers’ autonomy-supportive behavior by the multi-dimensional scale (Multi-Dimensional Perceived Autonomy Support Scale for Physical Education). The participants were 1,476 students aged 12- to 15-years-old. In Study 1, a pool of 37 items was generated based on past literature and feedback from students and academic experts. In Study 2, the factorial structure of the questionnaire was tested using exploratory and confirmatory factor analysis. The confirmatory factor analysis yielded a final 15-item three-factor solution of the Multi-Dimensional Perceived Autonomy Support Scale for Physical Education, covering organizational, procedural, and cognitive dimensions of perceived autonomy support. In Study 3, the incremental validity of the Multi-Dimensional Perceived Autonomy Support Scale for Physical Education was supported. The results provided initial evidence for the reliability and validity of the Multi-Dimensional Perceived Autonomy Support Scale for Physical Education, as well as its invariance across gender and age. Suggestions for the use of the scale and further research are discussed.
