What is influencing the dropout behaviour of youth players from organised football?

This article provides a systematised review of relevant factors influencing youth dropout from organised football. The findings of identified 30 studies concerning dropout behaviour in football indicate the multidimensional influences of intrapersonal, interpersonal and structural factors. Most studies investigate the influence of intrapersonal factors. Accordingly, negatively perceived football competence, lack of motivation, goals and incentives and a lower relative age lead to a higher dropout rate. At the interpersonal level, lack of support from significant others (parents, peers, coach) and a disadvantageous team situations promote withdrawal from organised youth football. A lack of organisational and structural conditions promote dropout too. Based on this review, the following identified research gaps should be addressed in future studies: (1) analysis of individuals’ dropout decision as a selection of available alternatives, (2) referencing to corresponding contextual features of dropout behaviour, (3) the longitudinal perspective at dropout behaviour and (4) the perspective of intervention. Furthermore, some practical implications can be derived for the management of youth members in football clubs: (1) strengthen and develop successive coaching competencies, (2) reflection of own club philosophy against the background of divergent expectations of adolescents, (3) measures to promote identification with the football club and (4) anchoring of orientation regarding to young players as a central objective in the club.     

Does a perceptuomotor skills assessment have added value to detect talent for table tennis in primary school children?

ABSTRACT

Talent detection intends to support lifelong sports participation, reduce dropouts and stimulate sports at the elite level. For this purpose it is important to reveal the specific profile which directs children to the sports that connect to their strengths and preferences. This study evaluated a perceptuomotor skills assessment as part of talent detection for table tennis, a sport in which perceptuomotor skills are considered essential to cope with the difficult technical aspects. Primary school children (n = 121) and gifted young table tennis players (n = 146) were assessed using the Dutch perceptuomotor skills assessment measuring “ball control” and “gross motor function”. A discriminant function analysis confirmed the added value by identifying primary school children fitting the table tennis perceptuomotor profile of the young gifted table tennis players (28%). General linear model analyses for the assessment’s individual test items showed that the table tennis players outperformed their primary school peers on all “ball control” items (P < 0.001). In conclusion, the assessment appears to be of added value for talent detection in table tennis at this young age. Longitudinal studies need to reveal the predictive value for sports participation and elite sports.     

Predicting biathlon shooting performance using machine learning

Shooting in biathlon competitions substantially influences final rankings, but the predictability of hits and misses is unknown. The aims of the current study were A) to explore factors influencing biathlon shooting performance and B) to predict future hits and misses. We explored data from 118,300 shots from 4 seasons and trained various machine learning models before predicting 34,340 future shots (in the subsequent season). A) Lower hit rates were discovered in the sprint and pursuit disciplines compared to individual and mass start (P < 0.01, h = 0.14), in standing compared to prone shooting (P < 0.01, h = 0.15) and in the 1^st prone and 5^th standing shot (P < 0.01, h = 0.08 and P < 0.05, h = 0.05). B) A tree-based boosting model predicted future shots with an area under the ROC curve of 0.62, 95% CI [0.60, 0.63], slightly outperforming a simple logistic regression model and an artificial neural network (P < 0.01). The dominant predictor was an athlete’s preceding mode-specific hit rate, but a high degree of randomness persisted, which complex models could not substantially reduce. Athletes should focus on overall mode-specific hit rates which epitomise shooting skill, while other influences seem minor.     

Apprentice or Student? The Structures of Construction Industry Vocational Education and Training in Denmark and Sweden and their Possible Consequences for Safety Learning

There is a notable difference in occupational injury rates in the two Scandinavian countries, Sweden and Denmark, with the latter having a 40% higher rate of fatal occupational injuries in the construction industry. This study explored differences in the vocational education and training (VET) systems between Sweden and Denmark that may be important for students’ safety learning and practice during VET. In both countries, students participate in full-time education, and the curriculum includes school-based as well as company- based training. However, during company- based training Swedish students retain their student status, whereas Danish students are employed as apprentices. From a perspective of viewing safety as a social practice developed through interactions of different social and institutional bodies, the analysis points to this difference in employment status as important for their safety practices and also for the teachers’ position to influence safety learning and practices during company-based training. An analysis of interview and survey data focusing on how VET students enact safety ‘knowings’ across learning sites, suggest how different forms of connectivity models in VET promote various forms of safety learning among students.     

Violent Extremism,National Security and Prevention. Institutional Discourses and their Implications for Schooling

Currently, threats to societal security from extremist groups are high on the political agenda in many countries. Politicians, policymakers at various levels and communities are searching for methods to counteract recruitment to violent organizations. These efforts are often referred to as Prevention of Violent Extremism (PVE-programmes). One of the earliest PVE programmes in Europe was the British PREVENT programme, and it has to some extent served as a model for other countries, including Sweden. In this article, we scrutinize a particular method, inspired by the PREVENT, and developed by the Swedish National Coordinator against violent extremism, called The Conversation Compass (CC) intended for so-called front-line workers. This article reports an analysis of this method in order to provide a broader understanding of how the discourse on preventing violent extremism meanders from political and policy discourses into claims about how to organize educational practices and social work and the regulations under which these institutions operate. The results show that the CC contributes to a securitization of the educational system in ways that are not in line with educational traditions of schools in Sweden, or with the laws and policies that regulate the educational system.     

Newly qualified teachers’ professional digital competence: implications for teacher education

The professional digital competence (PDC) of teachers is of growing importance in classrooms, now that digital resources and digital media are becoming important parts of teachers’ everyday practice. This study explores how newly qualified teachers are prepared to use information and communication technology (ICT) in their initial teacher education (ITE). We present findings of a nationwide survey in Norway on 356 newly qualified teachers. It explores how these teachers’ ICT self-efficacy is related to how they perceive the quality of, and contributions from, their ITE related to ICT and the development of their PDC. In general, newly qualified teachers report fairly poor quality and contribution of ICT training during their teacher education. We claim that continuous effort is needed to review the quality of ITE and contribute specifically to the development of PDC and developing student teachers’ ICT self-efficacy in ITE.     

Students’ Ability to Apply Their Knowledge in a Gaming Exercise: An Exploratory Study

This paper reports on a study exploring master students’ ability to apply their knowledge when solving an internal pricing problem in a supply chain. Analyses of 33 negotiation progress reports and 8 recordings of discussions demonstrate that most of the students were not able to apply relevant concepts and models to guide their handling of the task. The main reason for the variability in performance was the significant differences in the students’ general problem-solving abilities. Most students did not perform a thorough task analysis or develop a solution strategy before they met for negotiations, and they did not keep track of their task performance. The implications for teaching are highlighted, and directions for further research are proposed.     

Reciprocal peer assessment as a learning tool for secondary school students in modeling-based learning

The aim of this study was to investigate how reciprocal peer assessment in modeling-based learning can serve as a learning tool for secondary school learners in a physics course. The participants were 22 upper secondary school students from a gymnasium in Switzerland. They were asked to model additive and subtractive color mixing in groups of two, after having completed hands-on experiments in the laboratory. Then, they submitted their models and anonymously assessed the model of another peer group. The students were given a four-point rating scale with pre-specified assessment criteria, while enacting the peer-assessor role. After implementation of the peer assessment, students, as peer assessees, were allowed to revise their models. They were also asked to complete a short questionnaire, reflecting on their revisions. Data were collected by (i) peer-feedback reports, (ii) students’ initial and revised models, (iii) post-instructional interviews with students, and (iv) students’ responses to open-ended questions. The data were analyzed qualitatively and then quantitatively. The results revealed that, after enactment of the peer assessment, students’ revisions of their models reflected a higher level of attainment toward their model-construction practices and a better conceptual understanding of additive and subtractive color mixing. The findings of this study suggest that reciprocal peer assessment, in which students experience both the role of assessor and assessee, facilitates students’ learning in science. Based on our findings, further research directions are suggested with respect to novel approaches to peer assessment for developing students’ modeling competence in science learning.
