Vielseitigkeit als Ausbildungsstrategie im leistungssportlichen Nachwuchstraining

This paper presents an excerpt from a comprehensive study on the concepts of long-term athlete development. Following a qualitative research methodology and using a hermeneutic-reconstructive procedure the purpose of this paper was to gain insight into expert youth sports coaches’ understanding of the two main trajectories leading to elite performance: early specialization and early sampling. Analysis of the transcribed interviews suggests that the training strategy is primarily the result of a complex decision making process. Additionally, coaches perceived a trend towards early specialization which conflicts with existing considerations of long-term athlete development. The results of this study provide an opportunity to understand the subject of diversification in youth sports and to raise awareness for the problems of practitioners.     

The Nature and Role of Common Ground in the Learning of Mathematics in Small-Group Discussions

This study investigates the nature and role of common ground in group learning of mathematics by means of the analytical constructs of focal projects and contextualization. The analysis investigates two students (12–13 years old) playing a dice game, where their task is to distribute a set of markers based on the total of two dice. The analysis shows how consistency between the students' focal projects became crucial in their progression from a uniform to a non-uniform distribution of the markers used in the game. The task system and concrete manipulatives became important in furthering the students' explorations. In the frame of a frequency context, we also discuss how a contextualization may restrict certain aspects of probability from coming into play during such explorations.     

The objectification of the right-angled triangle in the teaching of the Pythagorean Theorem: an empirical investigation

In this paper, we present the design and the results of a teaching experiment carried out to investigate the hypothesis that it is feasible to facilitate the students’ possibility for experiencing the reactivation of the objectification of the right-angled triangle. For this purpose, a teaching design of the Pythagorean Theorem was developed and taught to an experimental class of 14-year old students. The results of our teaching were compared with a control class with the employment of a questionnaire and semi-structured interviews. The quantitative and qualitative analyses supported our hypothesis that the students of the experimental class would develop qualitatively different understandings of the theorem than the control class, thus suggesting their possibility for experiencing the reactivation of the objectification of the right-angled triangle.

Ein Beitrag zur systematischen Sportgeräteentwicklung

Sporting goods companies face significant challenges. As a result, the importance of a structured and systematic product development process has increased. There are several paradigms to support the product development, with the integrated product development paradigm as one of the most important ones. This study aims at the verification of an efficient application of Integrated Product Development for the development of sports equipment. For that purpose Insider Action Research is used. Three different case studies (leisure, fun and professional sports market) were conducted and analysed. To objectify the results, objective and subjective efficiency criteria were defined. The results show a positive evaluation of the criteria. So far, the development projects have been performed in an academic context only.     

Caring and Daring Discourses at Work: Doing Gender Through Occupational Choices in Elderly Care and Police Work

This paper aims to problematise how gender is being done—1. through occupational choices in two occupations that are traditionally gender divided, elderly care and police work, and 2. through the division of work assignments in police work. Interviews with care workers and police officers are analysed using a “doing gender” perspective, a post-structural notion of subjectivity inspired by Michel Foucault and positioning theory. We argue that a caring discourse operates in elderly care workers’ and police officers’ statements concerning occupational choices, while a daring discourse operates in statements concerning occupational choices within police work. Through these discourses, gender is being done in different ways; caring dispositions are constructed as totally female within the context of elderly care but as more gender-neutral in police work. At the same time, a macho or daring attitude is constructed as a male attribute in police work. Such constructions may have social consequences in terms of dividing work tasks for police, where male officers work in more prestigious and “dangerous” areas, while female officers are left with less prestigious, more caring-associated working areas.
