When favourites fail: Tournament trophies as reward cues in tennis finals

Abstract

In tournaments in various sports that feature one–on–one competition, the trophy is sometimes prominently displayed near the athletes during the final. Based on recent research on subtle reward cues, we propose that such trophies have the potential to induce choking under pressure in the match favourites, who are known to be most at risk. To test this idea, we analysed real-life tennis performance data (service performance and rally performance) from professional tournaments. While favourites generally outperformed underdogs during rallies, they did not do so in finals in which (a) large amounts of money were at stake and (b) a trophy was on display near the court. These findings support the idea that tournament trophies may distract favourites by continuously reminding them of what is at stake, and via that route may severely thwart their performance.     

Dynamics of the martial arts high front kick

Fast unloaded movements (i.e. striking, throwing and kicking) are typically performed in a proximo‐distal sequence, where initially high proximal segments accelerate while distal segments lag behind, after which proximal segments decelerate while distal segments accelerate. The aims of this study were to examine whether proximal segment deceleration is performed actively by antagonist muscles or is a passive consequence of distal segment movement, and whether distal segment acceleration is enhanced by proximal segment deceleration. Seventeen skilled taekwon‐do practitioners were filmed using a high‐speed camera while performing a high front kick. During kicking, EMG recordings were obtained from five major lower extremity muscles. Based on the kinematic data, inverse dynamics computations were performed yielding muscle moments and motion‐dependent moments. The results indicated that thigh deceleration was caused by motion‐dependent moments arising from lower leg motion and not by active deceleration. This was supported by the EMG recordings. Lower leg acceleration was caused partly by a knee extensor muscle moment and partly by a motion‐dependent moment arising from thigh angular velocity. Thus, lower leg acceleration was not enhanced by thigh deceleration. On the contrary, thigh deceleration, although not desirable, is unavoidable because of lower leg acceleration.     

Who's Responsible for the Digital Divide? Public Perceptions and Policy Implications

Addressing the reasons for—and the solutions to—the “digital divide” has been on the public agenda since the emergence of the Internet. However, the term has meant quite different things, depending on the audience and the context, and these competing interpretations may in fact orient toward different policy outcomes. The goals of this article are twofold. First, the authors unpack the term “digital divide” and examine how it has been deployed and interpreted across a range of academic and policy discourses. Second, through a framing experiment embedded within a nationally representative survey, the authors demonstrate how presenting respondents with two different conceptual frames of the digital divide may lead to different perceptions of who is most accountable for addressing the issue. From this, they discuss the dynamic relationship between the construction and communication of policy discourse and the public understanding of the digital divide, as well as implications for effective communication about the digital divide and information and communication technology policy to the general public.     

Creation of new routines in physical education: second-order reflection as a tradition-challenging form of reflection stimulated by inquiry-based learning

ABSTRACT

The time we live in is characterised by social and cultural changes, but teaching in physical education (PE) does not necessary match these changes. Consequently, the present project explored how second-order reflection (SoR) as a tradition-challenging and developing form of reflection can be stimulated by an inquiry-based learning (IBL) approach in physical education teacher education to transform current pedagogy to align with social and cultural changes. SoR fosters development and learning by inter-professional collaboration and inter-professional dialogue and is an extended form of higher-order thinking (HoT) including critical thinking and problem-solving. The project explored how an IBL approach stimulated a group of pre-service teachers (n?=?32) developing their professional practice by using SoR. Data were generated through video observations and audio recordings of the pre-service teachers’ discussions, reflections and actions during the IBL unit. Furthermore, written reflections regarding the challenges were collected. All data were inductively analysed in order to identify and extract common themes and patterns in relation to SoR. The analyses of the data revealed that during the IBL approach the pre-service teachers used both reflection at first and second-order level. Reflections in the form of technical and practical considerations were common, while examples of SoR were seen especially in the phases of IBL where the pre-service teachers used new theoretical knowledge and experiences from other contexts than PE. Consequently, the findings supported that IBL enhanced the second-order reflective skills of some of the pre-service teachers. However, with further use of guiding and facilitation of the IBL process or keeping the pre-service teachers to their challenges, hypotheses and plans, the methodology has even more potential to enhance the second-order critical reflection of the participants; thereby developing their coming practice to be more reflective, engaging and probably motivational.     

Learning from instruction: the case of mathematics

Starting from a brief analysis of adaptive competence in mathematics, this article describes a series of research-based characteristics of the kind of learning processes that should be elicited in students to facilitate and support in them the progressive acquisition of such competence. Four major characteristics are discussed in some detail: learning is constructive, self-regulated, situated or contextual, and collaborative. A rather new approach to transfer of learning is then presented in which transfer is conceived as the preparation for future learning. Throughout the article it is argued that, notwithstanding the progress made in research on learning from instruction, numerous and complex issues and problems remain for continued inquiry.
