A comparison of well-peer mentored and non-peer mentored athletes’ perceptions of satisfaction     

Matt D. Hoffmann  Todd M. Loughead 《Journal of sports sciences》2016,34(5):450-458

The purpose of the present study was to compare well-peer mentored and non-peer mentored athletes’ perceptions of satisfaction. A total of 444 intercollegiate athletes (272 well-peer mentored and 172 non-peer mentored) from a variety of sport teams participated in the study. Athletes from both well-peer mentored and non-peer mentored groups reported their satisfaction levels using the Athlete Satisfaction Questionnaire. The results of a MANOVA and follow-up post hoc ANOVAs showed that well-peer mentored athletes were significantly more satisfied than their non-peer mentored counterparts in terms of individual performance, personal dedication, team task contribution, team social contribution, team integration, ethics, ability utilisation and training and instruction. Overall, the findings suggest that athletes who are well-peer mentored by a teammate perceive higher satisfaction levels with various aspects of their athletic experience than athletes who are not peer mentored by a teammate. Given these positive findings, practitioners (i.e., coaches, sport psychology consultants) should inform athletes on the benefits of peer-to-peer mentoring. The practical implications of the results and strategies to promote peer athlete mentoring relationships in sport are highlighted.  相似文献

Motivbasierte Passung von Sportprogrammen     

Ass. Prof. Dr. Gorden Sudeck  Achim Conzelmann 《Sportwissenschaft》2011,41(3):175-189

Regarding the phenomenon of mood improvements through physical exercise, secondary analyses indicate that improvements can hardly be generalised. Rather, personal and situational factors need to be taken into consideration in order to define the effects in a more precise manner. This contribution investigates to what extent explicit motives and goals of individuals in middle adulthood can be considered as personal moderators of mood changes. Five exercise programmes were developed in a quasi-experimental design and were conducted over a 3-month intervention period. These programmes were based on the “motive-based types of sportsperson” (Sudeck, Lehnert & Conzelmann, 2011), which define groups of individuals with similar motive and goal profiles. One hundred and thirty-three individuals participated in either a programme tailor-made to their motive and goal profile or in a non-tailored programme. The influence of this motive-based tailoring was investigated based on the mood dimensions of valence, calmness and positive activation using handheld PCs during and after exercise sessions. Results indicate a moderating influence of explicit motives and goals. This moderation was however not a general one but rather depended on the exercise programmes’ specific goals and content as well as on individuals’ goals regarding recreation. These findings point towards a systematic consideration of explicit motives and goals in the planning of health and leisure sport programmes.  相似文献

Defining information—II: A quantitative evaluation of the information content of documents     

Eliahu Hoffmann 《Information processing & management》1982,18(3):133-139

For the quantitative determination of the information content (IC) of documents, two requisite parameters were defined. First, the information unit (IU) as the smallest unit consistent with our previous definition of information, and second, its connectivity (C), namely, the extent to which it is connected with other information units in the document. The total quantity of information contained therein is then a function of the number of information units, as well as their connectivities.  相似文献

Advisory work as assistance in problem-solving — Problem-solving models as basic concepts for advisory work     

Volker Hoffmann  Angelika Thomas 《The Journal of Agricultural Education and Extension》2013,19(2):61-73

Abstract

This article summarises some basic concepts of advisory work, incorporated into novel forms of extension over the past half century at Hohenheim University, Stuttgart, Germany. It emphasis a certain understanding of advisory work: as support through “mental help” in structuring and restructuring by informing, motivating and enabling. Through exercises given in the article one can get the idea that problem situations are determined by one's own lack of insight and difficulties in breaking through the limitations of perceptions. The concept presented here in “stages of systematic problem-solving” starts with the perception of a problem by the client. The further critical steps are described within this process from perception of a problem towards solutions and evaluation of results. Two other models that are useful in thinking about problem-solving are also presented. Advisors should value them and be able to make use of them in a flexible way.  相似文献   

Promoting schoolchildren’s self-esteem in physical education: testing the effectiveness of a five-month teacher training     

Benjamin Rubeli  Esther Oswald  Achim Conzelmann  Jürg Schmid  Stefan Valkanover 《Physical Education & Sport Pedagogy》2020,25(4):346-360

ABSTRACT

Background: Schoolchildren’s personality development is considered a central goal of physical education (PE). With regard to the relationship between psychological well-being and global self-esteem over the life course, the promotion of positive self-esteem is an issue of particular significance. Past research revealed that PE taught with an individualized teacher frame of reference (iTFR) and a reflexive teaching style is associated with positive effects on facets of children’s perceived sports competence. However, it remains an open question whether this teaching styles has the potential to promote positive self-esteem.

Purpose: The present study investigated whether a five-month teacher training, aimed to enhance the teachers’ iTFR and their reflexive teaching style in PE, has a positive effect on students’ perceived sports competence and their global self-esteem. To analyse the implementation quality, changes in students’ perceived iTFR and perceived reflexive teaching style were investigated.

Method: A total of 21 teachers were assigned to either an intervention group (n?=?13), receiving the five-month teacher training, or a control group (n?=?8) consisting of regular teaching without teacher training. The teacher training encompassed five three-hour consecutive sessions during which the teachers acquired theoretical and practical knowledge about the promotion of competence perceptions in PE with a reflexive teaching style and an iTFR. Between the sessions, the teachers were instructed to implement an iTFR and a reflexive teaching style into their own PE classes. To evaluate the effects of the teacher training, their students’ (N?=?315, 53.7% girls, M_age?=?13.2 y, SD_age?=?1.3 y) perceived teaching style (iTFR and reflexive teaching), perceived sports competence and global self-esteem were measured with paper-pencil questionnaires at three measurement points (pre, post and follow-up).

Findings: Linear mixed effect models showed that students of the intervention group reported an increase in their teachers’ reflexive teaching style, but there were no changes with regard to iTFR. With regard to students’ perceived sports competence and global self-esteem, there were significant interaction effects between time and group over a period of eight months (from pre-test to follow-up), indicating positive effects on these self-concept dimensions due to the teacher training.

Conclusion: The present study indicates that a long-term teacher training supports PE teachers to implement teaching styles with the aim to promote students’ self-concept. Furthermore, the findings lead to the assumption that a more pronounced iTFR in combination with an enhanced reflexive teaching style has the potential to positively influence schoolchildren’s perceived sports competence and global self-esteem.  相似文献
