How Language Supports Adaptive Teaching Through a Responsive Learning Culture

For students to learn optimally, teachers must design classrooms that are responsive to the full range of student development. The teacher must be adaptive, but so must each student and the learning culture itself. In other words, adaptive teaching means constructing a responsive learning culture that accommodates and even capitalizes on diversity to ensure that each student is learning optimally. There are 2 primary resources for accomplishing this, engagement and the classroom talk that the teacher orchestrates.     

Testing Measurement Invariance of Hedonic and Eudaimonic Entertainment Experiences Across Media Formats

The aim of this study is to investigate the measurement invariance of media users’ entertainment experiences as conceptualized by two-process models of entertainment (i.e., enjoyment and appreciation) across different media formats. With this purpose, the present research relates to the recent rise of entertainment research, embracing more and more media types and formats with which entertainment experiences may occur. At the same time, it addresses a methodological issue that has rarely been addressed in communication research. Focusing on one of the most often used measurement instruments in entertainment research, on three different media formats (political talk shows, comedies, and dramas), the study finds evidence for configural, metric, and scalar invariance for the scale. The theoretical and practical implications of the findings are discussed.     

IMPROVING PRODUCTIVITY IN THE NEWSROOM?

In an attempt to produce more news stories, faster and on different platforms, the national Danish Broadcasting Corporation, DR, has introduced a new workflow. This new workflow is based on principles and practices known internally as “the news engine,” and it has brought with it changes in regards to both the news products, the news processes and the individual news producers. This article is based on newsroom observations, interviews with employees and content analyses, and it shows how the practice of journalism at DR News has been altered in several ways after the implementation of the news engine. The changes in DR News have become the inspiration for other television stations, and the study concludes by discussing how this particular workflow affects the profession of journalism. Rather than a proletarianization of the profession, this study points to a polarization where some journalists experience a deskilling and a decrease in autonomy, while others experience an increase in autonomy as part of a process of reskilling and multiskilling.     

Differences in strength and speed demands between 4v4 and 8v8 small-sided football games

ABSTRACT

The aims of this study were (i) to characterise the acceleration demands of two different formats of small-sided game (SSG), i.e., 4v4 + goalkeepers (4v4 + GK) and 8v8 + goalkeepers (8v8 + GK); (ii) to analyse the correlation between performance in power-based tests and acceleration-based physical loading during the two different SSG formats and (iii) to analyse the neuromuscular-induced fatigue. Eighteen adult male footballers participated in the study (20.7 ± 1.0 years, 178 ± 5 cm and 71.4 ± 2.1 kg). Baseline measurements were obtained from countermovement jumps, 15 s repeated jumps and 5 and 15 m sprints. A total of 36 min was analysed for each SSG (4v4 + GK: two sets of 3 × 6 min, and 8v8 + GK: 2 × 18 min). Heart rate, blood lactate, perceived exertion and movement pattern (GPS) were analysed. Distances covered by very-high-intensity activities and very-high-speed running were lower in 4v4 + GK than in 8v8 + GK (effect sizes (ES) = ?0.69 ± 0.67 and ?1.04 ± 0.67, respectively; very likely), while accelerations and decelerations were higher in 4v4 + GK than in 8v8 + GK (ES = 1.13–1.52; almost certainly). Blood lactate concentrations were higher (ES = 1.40 ± 0.58; almost certainly) and players perceived themselves to be more tired (ES = 0.80–2.31; almost certainly) after 4v4 + GK than after 8v8 + GK. Sprint ability in 5 and 15 m tests decreased (ES = 0.87 ± 0.58 and 0.89 ± 0.58, respectively; almost certainly) only after 4v4 + GK. This SSG format appeared more demanding in relation to repetitions and fatigue development of muscle power-based actions than 8v8 + GK. It may therefore be logical to use the former type of SSG to target development of power-related football actions.     

Early Football and the Emergence of Modern Soccer: A Reply to Tony Collins

This paper seeks to defend one part of what has become known as the ‘revisionist’ account of the historiography of football in nineteenth-century England. In so doing, it responds to the critique by Tony Collins in his article ‘Early Football and the Emergence of Modern Soccer’ between 1840 and 1880, calling into question the reliance in his arguments of what he describes as ‘legal organized games’ as the only measure of a football culture outside of the public schools. His classification of small-sided games of football as an ‘informal leisure practice or folk custom’ is also interrogated and found wanting. Alternatively, further evidence is presented from 1860 of football games played in a variety of forms, usually alongside other sports, and mainly on church, works’ or schools’ outings, at rural fetes, galas and celebrations, or as street or casual football, the latter taking place in meadows, fields, and greens. Importantly, these were predominantly small-sided games and are, arguably, the ones closest to Association football, as it was codified in 1863, and constituted a broad, tenacious, and increasingly visible football culture that existed amongst the general population across mid-century uninfluenced by the public schools and public school boys.     

The development and validation of the Interpersonal Support in Physical Activity Consultations Observational Tool

This study describes the development and psychometric characteristics of an observational instrument that examines four aspects of interpersonal support (or lack of) provided during physical activity (PA) promotion consultations (i.e., Autonomy Support, Involvement, Structure and Interpersonal Control), as identified by Self-determination Theory (SDT). The reliability and validity of the Interpersonal Support in Physical Activity Consultations Observational Tool (ISPACOT) were examined within an exploratory randomised control trial. Recorded consultations (N = 42) conducted by qualified PA advisors (N = 14) at 13 leisure centres across the West Midlands (UK) were rated. Intra-class correlation coefficients (ICC) indicated moderate to high inter-rater reliability for overall interpersonal support (0.80), and the Autonomy Support (0.74), Involvement (0.73) and Structure (0.91) dimensions, but low reliability for Interpersonal Control (0.35). The advisors, who conducted PA promotion consultations that were rated as low in their interpersonally supportive features, were perceived by their clients as being less supportive (F(1,10) = 5.0, p <.05). Ratings on the ISPACOT differentiated advisors who were trained in SDT principles and those who were not. Overall, the findings provided preliminary evidence for the reliability and convergent validity of the ISPACOT.     

Training the inspiratory muscles improves running performance when carrying a 25 kg thoracic load in a backpack

Load carriage (LC) exercise in physically demanding occupations is typically characterised by periods of low-intensity steady-state exercise and short duration, high-intensity exercise while carrying an external mass in a backpack; this form of exercise is also known as LC exercise. This induces inspiratory muscle fatigue and reduces whole-body performance. Accordingly we investigated the effect of inspiratory muscle training (IMT, 50% maximal inspiratory muscle pressure (P_Imax) twice daily for six week) upon running time-trial performance with thoracic LC. Nineteen healthy males formed a pressure threshold IMT (n?=?10) or placebo control group (PLA; n?=?9) and performed 60?min LC exercise (6.5?km?h^–1) followed by a 2.4?km running time trial (LC_TT) either side of a double-blind six week intervention. Prior to the intervention, P_Imax was reduced relative to baseline, post-LC and post-LC_TT in both groups (pooled data: 13?±?7% and 16?±?8%, respectively, p?P_Imax increased +31% (p?TT (+18%, p?P_Imax at each time point was unchanged (13?±?11% and 17?±?9%, respectively, p?>?.05). In IMT only, heart rate and perceptual responses were reduced post-LC (p?p?相似文献
