ABSTRACT

Studies that have analysed the association between the different movement behaviours and fundamental movement skills (FMS) have considered it in an independent manner, disregarding the compositional nature of 24-h movement behaviours (24-h MB). The aim of this study was to investigate the relationship between the 24-h MB and FMS in preschoolers using a compositional data analysis . Two hundred and four preschoolers (4.5 ± 0.8 years old; 101 boys) provided objectively assessed physical activity (PA) and sedentary behaviour (SB) data (Actigraph wGT3X), and FMS (TGMD-2). Sleep duration (SD) was reported by parents. Association of daily composition of movement behaviours with FMS was explored using compositional analysis and isotemporal substitution (R Core Team, 3.6.1). When considered as a 24-h MB composition (PA, SB and SD), adjusted for age, BMI and sex, the composition predicted locomotor (r2 = 0.31), object control (r2 = 0.19), and total motor score (r2 = 0.35), respectively (all P < 0.001). Reallocation of time from light to moderate-to-vigorous PA was associated with greatest positive changes in total motor score. Achieving adequate balance between movement behaviours over the 24-h period, and its relationship with locomotor and object control skills should be considered and further investigated in early childhood.  相似文献

Student hand-raising is an everyday behavior in classroom interactions with teachers. This research presents two studies that examine the variance in hand-raising and its relation to student motivation in two school subjects, Mathematics and Language Arts. Student hand-raising is introduced as an indicator of behavioral engagement. Study 1 investigated N = 397 high school students in 20 classrooms during a videotaped lesson in each subject. Multilevel regression analysis suggests that student motivation accounts for significant variance in hand-raising. The results show subject-specific differences: Student self-concept predicts hand-raising in Mathematics, while students' situational interest predicts their hand-raising in Language Arts. Students’ externally regulated motivation is predictive across both subjects. In Study 2, N = 14 high school students were interviewed about their hand-raising behavior. The results validate and extend the findings from Study 1. Finally, this research emphasizes the importance of fostering student hand-raising and discusses the implications for future research.  相似文献

The purpose of the present study was to assess an instrument that uses responses from teachers to measure principal behaviors on the critical educational issue of school renewal. To account for the data hierarchy of teachers nested within schools, we employed a multilevel confirmatory factor analysis and estimated multilevel reliabilities at both teacher and school levels to examine the instrument. With 2765 teachers from 148 schools, the instrument showed acceptable structural validity. Specifically, we found that when teachers provide responses as indicators of school renewal, the instrument can generate a valid and highly reliable measure or estimate of school renewal at the school level. However, data analysis at the teacher level attempting to use teacher perceptions of school renewal as either dependent variables or independent variables should be avoided because of the low reliability at the teacher level.  相似文献

ABSTRACT

This study aimed to assess which combination of subjective and empirical data might help to identify the expertise level. A group of 10 expert coaches classified 40 participants in 5 different expertise groups based on the video footage of the rallies. The expertise levels were determined using a typology based on a continuum of 5 conative stages: (1) structural, (2) functional, (3) technical, (4) contextual, and (5) expertise. The video allowed empirical measurement of the duration of the rallies, and tri-axial accelerometers measured the intensity of the player’s involvement. A principal component analysis showed that two dimensions explained 54.9% of the total variance in the data and that conative stage and empirical parameters during rallies (duration, intensity of the game) were correlated with axis 1, whereas duration and acceleration data between rallies were correlated with axis 2. A random forest algorithm showed that among the parameters considered, acceleration, duration of the rallies, and time between rallies could predict conative stages with a prediction accuracy above possibility.

This study suggests that performance analysis benefits from the confrontation of subjective and objective data in order to design training plans according to the expertise level of the participants.  相似文献

This study addresses measurement issues around a standards-based content analysis of mathematics textbooks’ coverage of standards for use in large-scale monitoring of standards implementation as proposed in a 2013 report by the National Research Council. An earlier study produced an exhaustive content analysis of textbooks using the 2012 Common Core State Standards for Mathematics. This yielded an accurate and reliable portrait of a textbook's coverage of standards. However, such an in-depth analysis is not feasible for large-scale standards-implementation monitoring in which a large number of textbooks may need to be analyzed. To provide such a portrait with sufficient accuracy while also substantially reducing the associated resources needed to produce such a portrait, a simulation study was conducted with the exhaustively coded database to compare different sampling schemes. Results indicated that sampling 1 day from each week and coding the corresponding lessons led to sufficiently accurate representations of the overall content of the textbook. The results provide empirical evidence for large-scale standards-based content analyses of mathematics textbooks for monitoring standards implementation which could be adapted for other subject areas.  相似文献

采用实地问卷调查法,收集马拉松参赛者在运动参与行为、实物购买行为和人口特征方面的统计数据,使用k-means聚类分析将马拉松消费者细分为资深马拉松追求者、普通马拉松爱好者和社交者三个集群。研究表明,马拉松消费将面临以下挑战:泛娱乐性大于竞技性造成资深消费群体流失,赛事体系层级不清晰造成消费者混淆,赛事运营服务不专业拉低消费意愿,其他户外运动兴起导致消费份额分化,马拉松消费者非理性消费观念广泛存在。预测未来马拉松消费行为发展的六大趋势:以重点人群为目标扩大马拉松消费;科学跑马服务助力消费者持续参与赛事;沉浸体验式消费不断升级;建设马拉松产业载体拓展消费空间;社交媒体互动式消费发挥中介作用;5G开启智能马拉松消费时代。  相似文献

A named professional with responsibility for overseeing and coordinating the educational inclusion of pupils with special educational needs and disabilities has become an important school role in many countries. In England, the SENCO (special educational needs coordinator) became a mandatory role in 1994, and associated mandatory training was introduced in 2009. A questionnaire survey of 618 in-training and actual SENCOs revealed that their motivating interest in becoming a SENCO varied. An exploratory factor analysis of 32 items covering different interests in the role yielded four interest factors in becoming a SENCO: outward-facing factors (‘inclusion’ and ‘high-quality provision’) and inward-facing factors (‘educational and professional development’ and ‘leadership voice and status’). The outward-facing factors were viewed as more important to respondents than the inward-facing factors. Interest factors did not interact with organisational variables, including age group taught and school quality. Nevertheless, younger SENCOs and those engaged in training were more motivated by educational and professional development. SENCOs holding school leadership contracts were more motivated in developing leadership voice and status compared with their classroom teacher peers. Moreover, there was a significant overall difference with women reporting a higher interest than men across all factors.  相似文献
