Developing interactive mathematical talk: investigating student perceptions and accounts of mathematical reasoning in a changing classroom context

In recent years there has been an increased focus on the need for teachers to develop learning communities where all students have opportunities to engage in interactive discourse. However, there are few studies that focus on student perceptions and accounts of mathematical reasoning in classrooms with interactive mathematical talk as a focus of reform. A framework of teacher actions to develop classroom and mathematical practices was developed from classroom observations. Photo-elicitation interviews were used to investigate student perception and accounts of mathematical explanations and reasoning. The professional development programme, shifts in the teacher actions, and subsequent shifts in student perception and their recall of their own and peers’ mathematical reasoning over a school year are highlighted. Developing interactive dialogue in the classroom took considerable time and attention. Facilitating change to the way students both participated and understood their obligations required constant, ongoing attention to both the classroom and mathematical practices.     

How Counsellors Cope with Traumatized Clients: Personal, Professional and Organizational Strategies

This qualitative study examined the experiences of counsellors and their perceptions of resources that helped them cope with traumatized clients and difficult client sessions. The research was conducted using in-depth interviews with a purposive sample of eight counsellors working in five counselling agencies. The study identified how counsellors develop their own personal and professional strategies for coping with challenge, and the supportive structures and coping strategies provided by agencies. From these counsellors’ stories of learning to cope with traumatized clients and traumatic material, we highlight some recommendations that may facilitate the development of effective coping strategies for the prevention or amelioration of vicarious traumatization.     

Daily fluctuations in young children’s persistence

Children's behavior changes from day to day, but the factors that contribute to its variability are understudied. We developed a novel repeated measures paradigm to study children's persistence by capitalizing on a task that children complete every day: toothbrushing (N = 81; 48% female; 36–47 months; 80% white, 14% Multiracial, 10% Hispanic, 2% Asian, 1% Black; 1195 observations collected between January 2019 and March 2020). Children brushed longer on days when their parents used more praise (d = .23) and less instruction (d = −.22). Sensitivity to mood, sleep, and parent stress varied across children, suggesting that identifying the factors that shape an individual child's persistence could lead to personalized interventions.     

A case study comparison of objective and subjective evaluation methods of physical qualities in youth soccer players

ABSTRACT

Subjective and objective assessments may be used congruently when making decisions regarding player recruitment in soccer, yet there have been few attempts to examine the level of agreement between these methods. Therefore, we compare levels of agreement between subjective and objective assessments of physical qualities associated with youth soccer performance. In total, 80 male youth soccer players (13.2 ± 1.9 years), and 12 professional coaches volunteered to participate. Players were objectively assessed using five fitness measures: Yo-Yo Intermittent Recovery Test Level 1; Countermovement vertical jump; Functional Movement Screen?; 5/20 m sprint; alongside anthropometric measures. Additionally, coaches subjectively rated each player on the same five physical qualities using 5-point Likert scales. Inter-rater agreement between ratings from lead and assistant coaches was established for each age group. Moreover, Bayesian regression models were fitted to determine how well coach ratings were able to predict fitness test performance. Although inter-rater agreement between lead and assistant coaches was moderate-to-substantial (ω = 0.48–0.68), relationships between coaches subjective rating’s and corresponding fitness test performance were only highly related for the highest and lowest performing players. We suggest that while ratings derived from objective and subjective assessment methods may be related when attempting to differentiate between distinct populations, concerns exist when evaluating homogeneous samples using these methods. Our data highlight the benefits of using both types of measures in the talent identification process.     

From the field of play to the laboratory: Recreating the demands of competition with augmented reality simulated sport

ABSTRACT

Biomechanical analysis has typically been confined to a laboratory setting. While attempts have been made to take laboratory testing into the field, this study was designed to assess whether augmented reality (AR) could be used to bring the field into the laboratory. This study aimed to measure knee load in volleyball players through a jump task incorporating AR while maintaining the perception-action couplings by replicating the visual features of a volleyball court. Twelve male volleyball athletes completed four tasks: drop landing, hop jump, spike jump, and spike jump while wearing AR smart glasses. Biomechanical variables included patellar tendon force, knee moment and kinematics of the ankle, knee, hip, pelvis and thorax. The drop landing showed differences in patellar tendon force and knee moment when compared to the other conditions. The hop jump did not present differences in kinetics when compared to the spike conditions, instead of displaying the greatest kinematic differences. As a measure of patellar tendon loading the AR condition showed a close approximation to the spike jump, with no differences present when comparing landing forces and mechanics. Thus, AR may be used in a clinical assessment to better replicate information from the competitive environment.     

Canoe slalom – competition analysis reliability

The aim of this study was to assess intra-observer and inter-observer reliability of data gathered from a lapsed-time time–motion analysis of canoe slalom competition. The data were collected using a definition set developed in conjunction with elite canoe slalom coaches. Competition runs from four national-standard paddlers in a national selection race were analysed in random order three times by three observers. For each run, observers identified various events specific to canoe slalom, including time taken between gates, touched and missed gates, turn times, major and minor avoidance, rolls, paddle in and out of water times, and stroke classification. The error of measurement was determined for each of these variables. For time taken between gates and turn times, the error was ≤ 0.21 and ≤ 0.39 s for intra-observer and inter-observer analysis, respectively. The error for stroke in and out of water times was ≤ 0.08 and ≤ 0.13 s for intra-observer and inter-observer analysis, respectively. Analysis of stroke classification identification for intra-observer comparisons revealed that 91% of the time identical stroke identification occurred. Inter-observer analysis revealed identical stroke identification was achieved 81% of the time. These reliability data compare favourably with previous time–motion analysis in other sports using fewer variables.     

Aboriginal Football in Australia: Race Relations and the Socio-Historical Meanings of the 2014 Borroloola Tour to the Brazil World Cup

Abstract

This paper tells the history of the Borroloola Tour to the 2014 Brazil World Cup, when eight Aboriginal adolescent footballers from the remote town of Borroloola in Australia’s Northern Territory were selected to be part of a tour to Brazil. In Brazil they followed the Australian team from the stands, socialized with football idols such as Tim Cahill, and visited a Brazilian Indigenous tribe. John Moriarty, the first Aboriginal Australian to be selected to Australia’s national football team executed this excursion. Considering that race relations within the Australian sporting arena have historically, been tense and contested, this paper brings to light an under-explored aspect of football in Australia. It is timely too, given the insertion of Australian football within the Asian Football Confederation. The paper examines the historical meanings of the Borroloola Tour through the lens of its key participants; as well as by unveiling John Moriarty’s history as the first Aboriginal person to be selected to play for the Socceroos. In conclusion, it reveals that both the past and contemporary history of Aboriginal people’s involvement in Australian football has an emerging face that will shape football in Australia and in Asia in the coming years.     

Leadership and engagement in South Cambridgeshire District Council

How can action learning be used as part of an overall approach to changing the culture of an organisation? This article describes some of the work being done by managers in South Cambridgeshire district to build a more empowered and engaged organisation following the appointment of a new chief executive tasked with raising standards in an organisation which had had a challenging history, where morale was low and where significant reductions in the workforce were taking place. The article describes the purpose of action learning in this particular context, the membership of the action learning groups and the uses to which action learning is being put by managers in the Council.
