Abstract

In elite sport, to remain competitive at the international level, it is critical to understand the game demands on players to ensure sport specific training programmes are designed for optimal athlete preparation and conditioning. In netball, recent research examining the activity patterns of players at the elite level is lacking, with only one study undertaken on this level of competition in the past 30 years. Therefore, the aim of this study was to provide coaches with up to date knowledge of player activity patterns as a basis for the design of optimal sport specific training programmes. The Australian female netball team were analysed using video footage of three international test matches. Player activity was categorised into five movement and eight game-based activities; and further classified as work or rest. Results suggest that differences in the current game exist when compared to the previous analysis. Positional differences were also found with regard to player activity confirming the need for an individualised component of training based on player position.  相似文献

In order to better understand the effects of student-life stress on Education and Health Service majors (n?=?195) at a private, religious, Midwestern university in the USA, we assessed student perception of overall stress level and physical stress level using the Student-life Stress Inventory. The targeted sample consisted of students with declared majors that lead to careers involving interaction with vulnerable populations (i.e., children, individuals with disabilities, patients). Women in this study experienced a significantly higher (F?=?7.092 [1195], p?=?.008) overall stress level than their male counterparts. When the physical stress reaction scores were isolated, women still experienced significantly higher stress levels (F?=?7.758 [1195], p?=?.01). Regardless of gender, seniors and graduate students had an overall stress difference that was 11 points below that of freshman students in overall stress scores. There was a significant difference in the overall stress score (F?=?6.484 [2181], p?=?.001) between students who took 18 or more credit hours and those who took less. Students who worked more than four hours per week had a significantly higher overall stress level. Students in the age category 23+ had significantly less physical stress. There was a significant difference between students who prayed at least daily and students who never pray (F?=?1.114 [3188], p?=?.03). This study provides a valuable insight into the characteristics of individuals more likely to have difficulties adjusting to the demands of college life and the inherent stress of a profession in Education or Health Service.  相似文献   

Parameter Recovery and Classification Accuracy Under Conditions of Testlet Dependency: A Comparison of the Traditional 2PL,Testlet, and Bi-Factor Models     

Natalie A. Koziol 《教育实用测度》2013,26(3):184-195

ABSTRACT

Testlets, or groups of related items, are commonly included in educational assessments due to their many logistical and conceptual advantages. Despite their advantages, testlets introduce complications into the theory and practice of educational measurement. Responses to items within a testlet tend to be correlated even after controlling for latent ability, which violates the assumption of conditional independence made by traditional item response theory models. The present study used Monte Carlo simulation methods to evaluate the effects of testlet dependency on item and person parameter recovery and classification accuracy. Three calibration models were examined, including the traditional 2PL model with marginal maximum likelihood estimation, a testlet model with Bayesian estimation, and a bi-factor model with limited-information weighted least squares mean and variance adjusted estimation. Across testlet conditions, parameter types, and outcome criteria, the Bayesian testlet model outperformed, or performed equivalently to, the other approaches.  相似文献   

The relationship between vocabulary and writing quality in three genres     

Natalie G. Olinghouse  Joshua Wilson 《Reading and writing》2013,26(1):45-65

The purpose of this study was to examine the role of vocabulary in writing across three genres. Fifth graders (N = 105) wrote three compositions: story, persuasive, and informative. Each composition revolved around the topic of outer space to control for background knowledge. Written compositions were scored for holistic writing quality and several different vocabulary constructs: diversity, maturity, elaboration, academic words, content words, and register. The results indicated that students vary their vocabulary usage by genre. Story text had higher diversity than informative text as well as higher maturity as compared to persuasive text. Persuasive text contained higher diversity than informative text, and higher register than both of the other genres. Informative text included more content words and elaboration than the other text types as well as more maturity than persuasive text. Additionally, multiple regression and commonality analysis indicated that the vocabulary constructs related to writing quality differed by genre. For story text, vocabulary diversity was a unique predictor, while for persuasive text, content words and register were unique predictors. Finally, for informative text content words was the strongest unique predictor explaining almost all of the total variance in the five factor model, although maturity was also a unique predictor.  相似文献   

Associations Among Pubertal Development,Empathic Ability,and Neural Responses While Witnessing Peer Rejection in Adolescence     

Carrie L. Masten  Naomi I. Eisenberger  Jennifer H. Pfeifer  Natalie L. Colich  Mirella Dapretto 《Child development》2013,84(4):1338-1354

Links among concurrent and longitudinal changes in pubertal development and empathic ability from ages 10 to 13 and neural responses while witnessing peer rejection at age 13 were examined in 16 participants. More advanced pubertal development at age 13, and greater longitudinal increases in pubertal development, related to increased activity in regions underlying cognitive aspects of empathy. Likewise, at age 13 greater perspective taking related to activity in cognitive empathy‐related regions; however, affective components of empathy (empathic concern and personal distress) were associated with activity in both cognitive and affective pain‐related regions. Longitudinal increases in empathic ability related to cognitive and affective empathy‐related circuitry. Findings provide preliminary evidence that physical and cognitive‐emotional development relate to adolescents' neural responses when witnessing peer rejection.  相似文献

The Stability of Perceived Motor Competence of Primary School Children from Two Countries over One Year     

Carmen van Veen  Nadja Schott  Natalie Lander  Maike Tietjens  Trina Hinkley  Dennis Dreiskämper 《Measurement in physical education and exercise science》2020,24(1):74-80

ABSTRACT

Children’s positive perceived motor competence (PMC) provides motivation for physical activity. Theoretically young children (<8 years) have inflated PMC but as children cognitively develop, perceptions are hypothesized to decrease. This study investigated strength of PMC association over time, whether any change was negative (i.e. PMC decreased) and sex differences. A total of 198 children participated, 88 (44.4%) girls and 110 (55.6%) boys, aged 8.37–11.3 years at time point one (T1). Test–retest reliability using intraclass correlation was moderate for locomotor and moderate-to-good for object control perception. Hierarchical regression analysis showed PMC at T1 positively predicted significant variance one year later (T2) for locomotor (23.1%) and object control skill (5 items: 37.7%; 7 items: 39.9%). Whilst boys and girls differed on perception level there was no interaction between PMC and sex. Incongruent with previous theoretical perspectives this study identified stability in children’s PMC across an important developmental period.  相似文献   

Engineering work integrated learning placements: the influence of capitals on students’ access     

Megan Paull  Natalie Lloyd  Sally A Male  Teena Clerke 《Journal of Higher Education Policy & Management》2019,41(5):534-549

ABSTRACT

Work Integrated Learning (WIL) is embraced in Australian higher education (HE) and is a feature of most Australian HE ‘entry to profession’ engineering education programs accredited by Engineers Australia. Accreditation guidelines articulate the need for curriculum-integrated engagement with professional practice (EPP) and encourage EPP in a separate workplace environment, e.g. WIL. This article reports on the analysis of semi-structured interviews with staff and student engineers from four Australian HE institutions with mandatory engineering WIL. Framed by a Bourdieusian theoretical perspective, the influence of capitals on student access to engineering WIL placements was investigated. The research found that students’ capitals influenced access to engineering WIL placements. Policy and educational practice recommendations are made.  相似文献   

Observing justice in the primary school classroom     

Natalie Ehrhardt  Johanna Pretsch  Ivana Herrmann  Manfred Schmitt 《Zeitschrift für Erziehungswissenschaft》2016,19(1):157-190

Justice-related situations are a part of students? everyday life. In order to test the antecedents, correlates, and consequences of (in)justice in school, valid measures of justice are needed. To our knowledge, this is the first study to develop an observer low inference rating instrument that can be applied to measure justice in the primary classroom. In two pre-studies, justice-relevant situations in the classroom were extracted and observable indicators for these situations were developed. In the main study, this instrument was used to observe 208 primary school students with regard to their experiences of justice or injustice. In addition to this, other measures of justice were developed to examine the convergence between observer low inference ratings of classroom justice and high inference rating instruments for teachers, students, and external observers.Factor analyses and correlations between the different indices of the observer low inference rating and the high inference rating items suggested that incidents of justice and injustice in the classroom do not tend to co-occur frequently. Teachers do not appear to have a general tendency to treat a child more or less justly across a large number of situations.The findings suggest that a comprehensive assessment of classroom justice requires a multi-method approach where the justice ratings of students, teachers and external observers are all taken into consideration.  相似文献   

Using Wordless Picture Books to Support Emergent Literacy     

Mary Renck Jalongo  Denise Dragich  Natalie K. Conrad  Ann Zhang 《Early Childhood Education Journal》2002,29(3):167-177

Wordless books—picture books that rely entirely on illustrations to tell a story—are an excellent resource for educators of young children. This article provides a research-based rationale for using wordless books, offers a developmental sequence for introducing children to stories told through pictures, suggests a general strategy and wide array of early literacy activities based on books without texts, and recommends ways of communicating with parents/families about the value of wordless books. Outstanding wordless books and examples of children's responses to this growing genre of children's literature are also included.  相似文献
