An examination of the multidimensionality of situational interest in elementary school physical education

It has been demonstrated that situational interest in physical activity may derive from five dimensional sources, Novelty, Optimal Challenge, Attention Demand, Exploration Intent, and Instant Enjoyment. The purpose of this study was to examine the multidimensional sources in elementary school physical education. The five dimensions were measured in 5,717 students in third, fourth, and fifth grades from a random sample of 30 elementary schools. Students' responses were randomly divided into two samples for a two-step confirmatory factor analysis. The results confirmed that the five dimensions are primary sources of situational interest for elementary school physical education. The findings implied that situational interest should be taken into account as a necessary curricular component in elementary physical education.     

Content specificity of expectancy beliefs and task values in elementary physical education

The curriculum may superimpose a content-specific context that mediates motivation (Bong, 2001). This study examined content specificity of the expectancy-value motivation in elementary school physical education. Students' expectancy beliefs and perceived task values from a cardiorespiratory fitness unit, a muscular fitness unit, and a traditional skill/game unit were analyzed using constant comparison coding procedures, multivariate analysis of variance, X2, and correlation analyses. There was no difference in the intrinsic interest value among the three content conditions. Expectancy belief attainment, and utility values were significantly higher for the cardiorespiratory fitness curriculum. Correlations differentiated among the expectancy-value components of the content conditions, providing further evidence of content specificity in the expectancy-value motivation process. The findings suggest that expectancy beliefs and task values should be incorporated in the theoretical platform for curriculum development based on the learning outcomes that can be specified with enhanced motivation effect.     

Developing a Psychometric Instrument to Measure Physical Education Teachers’ Job Demands and Resources

Based on the job demands–resources model, the study developed and validated an instrument that measures physical education teachers’ job demands–resources perception. Expert review established content validity with the average item rating of 3.6/5.0. Construct validity and reliability were determined with a teacher sample (n = 397). Exploratory factor analysis established a five-dimension construct structure matching the theoretical construct deliberated in the literature. The composite reliability scores for the five dimensions range from .68 to .83. Validity coefficients (intraclass correlational coefficients) are .69 for job resources items and .82 for job demands items. Inter-scale correlational coefficients range from –.32 to .47. Confirmatory factor analysis confirmed the construct validity with high dimensional factor loadings (ranging from .47 to .84 for job resources scale and from .50 to .85 for job demands scale) and adequate model fit indexes (root mean square error of approximation = .06). The instrument provides a tool to measure physical education teachers’ perception of their working environment.     

我国网络谣言辟谣研究现状综述

以“中国期刊全文数据库”及“中国优秀博硕士学位论文数据库”的119篇文献为数据源进行分析,获知我国辟谣研究尚处在发展阶段,近两年学者在辟谣创新观点的研究上遇到瓶颈,大部分学者的研究关注点在于理论阐述谣言传播机制、谣言防控治理策略、自媒体平台和谣言热点事件,缺乏有说服力的实证研究数据支撑。因此,未来可从定量研究、防控网络谣言的预案机制、网络舆情监测技术和法制建设实践上展开实证研究。

Culturally Mixed Groups on International Campuses: an Opportunity for Inter‐cultural Learning

One of the major educational goals of the internationalisation of higher education is to prepare students to function in an international and inter‐cultural context. Cultural diversity on university campuses creates ideal social forums for inter‐cultural learning, yet, one of the most disturbing aspects of the internationalisation of higher education in Australia is the lack of interactions between local and international students from Asian backgrounds. This article examines the factors which students believe are affecting the formation of mixed groups for the completion of academic tasks. It also explores the nature of change in students’ perceptions after a successful experience of mixed group work. The focus on both local and international students’ appraisals of the situation highlights the two‐way, interactive nature of group formation and shows how both parties share some responsibility in the lack of cultural mix.
