Physical activity (PA) and exercise benefit both the mother and the fetus. Many pregnant women avoid or severely limit PA, leading to complications before and after delivery. This study elucidated the precise effect of each moderator variable on prenatal physical activity (PPA) by examining demographic factors, the PPA-related health belief level (HBL), and the current PPA level. The health belief model (HBM) in conjunction with the international prenatal physical activity questionnaire was used. The HBL in pregnant parous women (PPW) (3.42) was significantly higher than that in nonpregnant nulliparous women (NNW) (3.06). The PPA level in pregnant nulliparous women (PNW) (5.67 metabolic equivalent-hours per week (MET-h/week)) was lower than in the PPW (6.01 MET-h/week). All HBM dimensions (except for perceived barriers) were positively correlated with exercise expenditure in both PNW and PPW. According to the regression tree, participants in PNW aged ≤ 23 years with annual household incomes > CNY 100,001–150,000 had the highest energy expenditure (10.75 MET-h/week), whereas participants in PPW with a perceived benefit score of >4 had the highest energy expenditure (10 MET-h/week). The results demonstrated that the HBL in all groups was acceptable, whereas the PPA level was lower than the recommended PA level. In both PPW and PNW, the HBL was most strongly correlated with exercise expenditure. There is an urgent need to organize public-interest courses to alleviate household expenditure, raise the HBL about PPA in pregnant and NNW, and ensure personal health in the context of COVID-19.

The provision of advanced specialized content knowledge (SCK) that facilitates in-service teachers’ pedagogical content knowledge (PCK) is one aspect of physical education (PE) worth attention. To some extent, instructional models for training PE teachers on PCK implementation have been studied internationally. Cooperative learning (CL) is rarely reported in China, where direct instruction (DI) is commonly used to assist PE teachers. This study fills in the gaps and investigates whether PE in-service teachers receive proper training during short sessions to improve their PCK. We examined the effect of scaffolding procedures on in-service PE teachers’ PCK, skills, and self-efficacy compared to CL and DI. Hence, the question arose as to whether this support training provided by the instructor would assist in-service teachers in their perception of their efficacy as PE teachers. We deliberately selected 72 in-service PE teachers from twelve middle schools in Chengdu, Sichuan Province, China (23, 22, and 27 teachers for CL with scaffolding, CL, and DI conditions, respectively). CL and CLS participants were divided into mixed-sex teams using the CL procedure (Jigsaw) during the training session, while DI participants practiced the same training session in tandem. Pre- and post-tests were used to measure PE in-service teachers’ SCK, skills, and self-efficacy improvements. Additionally, PCK was also examined in the post-test. The mean scores for teaching self-efficacy, performance, and knowledge of practice for all three training conditions (CLS, CL, and DI) were similar at baseline. These parameters significantly differed between the three groups at the pre- and post-test. Post hoc tests revealed that participants in CLS programs improved their performance scores more from pre-test to post-test than participants in DI programs. Among CLS and CL participants, post hoc analyses indicated that their scores improved more significantly than those of DI participants between the pre- and post-tests. The correlation analysis showed positive correlations between post-test performance, PCK, and teaching self-efficacy in each condition. Direct access to teacher intervention information would be the key to developing instructional knowledge. CL training designs should incorporate scaffolding to help in-service teachers develop self-efficacy through physical activities.

Effective physical activity (PA) programs may enhance students’ awareness, competence, and motivation to participate in PA in the future for their health and mental well-being. The most effective way to accomplish this is through in-school and after-school activities. However, certain obstacles (traditional ways) may prevent some students from gaining these benefits. By eliminating these and other barriers, transforming after-school PA programs into in-school PA programs can enhance access to PA services. Despite this, the change in learning context from after-school to in-school may affect student engagement and program effectiveness by altering the interaction between students and teachers. Self-determination theory was employed to explain how the learning context affects motivation and social outcomes in PA programs for primary school students. The study involved 513 students from 12 different schools in Shanxi Province, China, in 2022. They represented 46.24% girls and 53.76% boys, ranging in age from 9 to 12. Teachers conducted PA programs to motivate students to participate in healthy activities. Assessment of student–teacher interactions, psychological needs satisfaction, and motivation was conducted among PA students through questionnaires. Relationships between students and teachers were incorporated into a structural equation model as direct and mediated determinants of motivation for attendance PA programs. There is agreement between the results and the hypothesized model, which predicts higher levels of psychological need satisfaction and higher levels of intrinsic motivation. In addition, the learning context only negatively affects less-self-determined motivations. Results confirm that positive perceptions of teachers by students play a significant role in promoting incentives for PA program participation in more self-determined manners. Furthermore, innovative strategies to reduce the detrimental effects of long-standing institutional structures and procedures should be considered and incorporated into in-school programs that motivate students to participate in these programs.

Although successful educational practices (SEPs) in higher education institutions have well-established student outcomes, the vast majority do not meet physical education standards in schools. Despite the promising nature of policy initiatives supporting schools, there is scant evidence of how these SEPs affect student outcomes. This review aimed to determine the status of the literature and the type of evidence regarding school SEPs. Several studies have demonstrated that these SEPs contribute directly or indirectly to improving student outcomes. Three objectives were examined and synthesized in our review of SEP research findings. The first goal is to identify different types of impacts on students in schools. The second goal is to provide educators, principals, and policymakers with a unified and comprehensive framework. Lastly, we provide suggestions for future SEP research. The review identified 45 studies that met our inclusion criteria. Our reviewed studies documented impacts on the individual level. It encompasses both students' instrumental abilities and their sense of self-esteem and motivation. Secondly, improving interpersonal relationships, reducing conflict, and increasing group cohesion are important components at the group level. Finally, there are factors at the community level, including absenteeism reduction, parental involvement, and changes in attitudes toward school. Current research supports the effectiveness of successful school practices. It stresses the importance of implementing policies to maximize student outcomes. Finally, the review concludes by discussing findings implications and future research directions.

Researchers have examined the common and specialized content knowledge (CCK/SCK) of physical education (PE) teachers and compared their pedagogical content knowledge (PCK) with student learning outcomes globally. However, little research has been reported in China on the relationship between PCK and student learning in PE settings. The aims of the study were (i) to investigate the influence of teacher content knowledge (CCK/SCK) on student development stages in PE settings and (ii) to examine the impact of teachers’ PCK on students’ performance in Tai Chi techniques (TCTs) after six days of instruction. Two PE teachers were chosen from two urban, public, mid-sized middle schools located in Chengdu, Sichuan Province, China. This study involved 332 students from six 5th and six 6th grade classes. The study consisted of 185 5th-grade students (98 boys and 87 girls) and 147 6th-grade students (70 boys and 77 girls). We examined how teacher PCK and student TCT changed after a professional development workshop (PDW). Each PE teacher had two classes randomly assigned to the control or experimental condition groups. This study had three phases. Initially, the control condition was introduced; then, a PDW was provided for the teachers; and finally, the experimental condition was implemented. Teaching behaviors were described using mean values, and t-tests based on the highest TCT scores were conducted to examine the effect of teachers’ PCK on students’ TCT learning. Furthermore, PCK effect sizes were calculated using Cohen’s d. Significant relationships existed between teachers’ PCK, CK, and students’ knowledge, with effect sizes ranging from 1.92 to 6.82. Additionally, improvements in teachers’ PCK were associated with improved TCT performance in students (p < 0.05). Increased knowledge and skills can improve teachers’ PCK behavior, resulting in improved student performance in TCTs. These findings may provide evidence for future recommendations regarding knowledge and skill training programs for physical education teachers.
