Navajo Female Participation In Volleyball: Its Impact/Correlation on Postsecondary Success

January 2012 (has links)
abstract: The purpose of this study was to identify, describe, and analyze Navajo female participation in high school volleyball and its affects on success in higher education. The research was an opportunity to gain an in-depth understanding of the impact athletics, namely volleyball, has within the Diné culture; and how the impact of those role models who provided leadership through athletic instruction had on the lives of Navajo female student athletes in their postsecondary experiences. The qualitative research was an opportunity to recognize that the interviewing process is synonymous and conducive to oral traditions told by Indigenous people. The population consisted of 11 Navajo female student athletes who were alumna of Monument Valley High School in Kayenta, Arizona, located on the Navajo Nation and who had participated in four years of Mustang volleyball from 2000-2010, either currently attending or graduated from a postsecondary institution, and although not a set criterion, played collegiate volleyball. Results indicated that participation in high school volleyball provided the necessary support and overarching influence that increased self-esteem or self-efficacy that led toward college enrollment, maintaining retention, and long-term academic success. Diné teachings of Aszdáá Nádleehé (Changing Woman) through the age old practice of the Kinaaldá ceremony for young Navajo pubescent girls marking their transition into womanhood, the practice of K'é, and Sa'ah naagháí bi'keeh hózhóón were all prominent Diné principles that resonated with the Navajo female student athletes. The leadership skills that the Navajo female student athletes acquired occurred based on the modification and adaptation of two cultures of two given societies: mainstream non-Native, Euro-centric society, and Diné society. The lifestyle, cultural beliefs, and teachings define the identity of female student athletes and the essence of their being.   / Dissertation/Thesis / Ed.D.

Compreensão da lógica do jogo na iniciação do voleibol : a contribuição das novas tecnologias /

Sarruge, Carina da Silva de Lara. January 2018 (has links)
Orientador: Fernanda Moreto Impolcetto / Resumo: A prática do voleibol vem se expandindo no Brasil desde a década de 1980, sobretudo pelas vitórias internacionais das seleções feminina e masculina, sendo as principais responsáveis pelo aumento do número de praticantes. A modalidade se manifesta de várias formas na sociedade, em vários lugares e para múltiplas finalidades, por isso deve ser motivo de reflexão também na iniciação. Embora as tecnologias estejam presentes no contexto esportivo de modo geral e no voleibol, pouco se encontra sobre sua utilização no sentido de melhorar a compreensão da lógica tática do jogo pelos praticantes, pois a prevalência do uso está em oferecer dados e respostas prontas, especialmente aos treinadores ou professores. Sendo assim, essa pesquisa teve como objetivo elaborar, implementar e avaliar uma Unidade Didática de iniciação ao voleibol, baseada na compreensão da lógica tática do jogo, a partir de um diagnóstico das dificuldades de ensino percebidas por professores de voleibol do SESC São Paulo, utilizando recursos de filmagem e Tecnologias de Informação e Comunicação (TIC) para auxiliar no processo de ensino-aprendizagem. A presente pesquisa é de natureza qualitativa com referencial teórico na pesquisa-ação e foi organizada em três etapas: 1) Levantamento diagnóstico com professores de voleibol do SESC São Paulo; 2) Elaboração de uma Unidade Didática de Voleibol e 3) Implementação e avaliação da Unidade Didática. Os professores indicaram, por meio do questionário, que "observar a quadra a...

The modality manifests itself in many ways in society, in many places and for multiple purposes, so it is also a reason for reflection on the initiative. Despite being in a position to improve the understanding of the tactical logic of the game for practitioners, there is a prevalence of use in data and ready-answers, especially the coaches or teachers. Thus, the research aims to develop, implement and evaluate a didactic unit of volleyball initiation, a program of learning difficulties of teaching by volleyball teachers of SESC São Paulo, filming resources and Information and Communication Technologies (ICT) to assist in the teaching-learning process. A qualitative research present with theoretical reference in action research and organization in three stages: 1) Diagnostic survey with SESC São Paulo volleyball teachers; 2) Elaboration of a Didactic Unit of Volleyball and 3) Implementation and evaluation of the Didactic Unit. The teachers indicated through the questionnaire that "they observe an opponent's court and pass the ball in the empty spaces" are like greater difficulties of the beginning students. Based on the use of the Teaching Games for Understanding (TGfU) model as resources of movies and other ICT (cell phone, tablet, notebook, projector, applicat...

Gaze behaviour of volleyball players during successful serve reception

Ramphomane-Aandahl, Bonolo January 2013 (has links)
The aim of this study was to identify and compare the gaze behaviour of both advancement levels (Advanced and Not Advanced) and genders (female and male) during successful serve reception. A quantitative, exploratory and quasi-experimental research design was used in which 50 ToppVolley Norway student athletes aged 16 to 19 years were sampled. The gaze behaviour of junior volleyball athletes was assesed as they received two types of serves (1 float and 1 top spin jump serve) and performed a forearm and/or overhead pass to a setter’s target while wearing an ASL mobile eye tracker. Gaze characteristics such as fixation number, fixation duration and areas of interest were used to achieve the aim of the study. The study found that Advanced participants differed from the Not Advanced athletes in employing fewer (9.70 ± 1.14 versus 10.77 ± 3.63 , p<.05, d>.20 ) fixations but for longer durations per fixations (1.64 ± 0.20 versus 1.60 ± 0.34, p<.05, d>.20 ) in receiving the float serve. Contrary, for the reception of the top spin jump serve, the Advanced athletes employed more fixations (12.11 ± 2.40 versus 11.83 ± 2.17, p<.05, d>.20 ) but for shorter durations per fixations (1.57 ± 0.26 versus 1.65 ± 0.34 sec, p<.05, d>.20 ) than the Not Advanced athletes. Male athletes in this study were more experienced than their female counterparts (5.97 ± 1.62 years versus 4.75 ± 1.59 years, p<.05, d>.20 ) with males employing more fixations than the females (11.02 ± 3.63 versus 9.19 ± 1.55 and 12.26 ± 2.46 versus 11.36 ± 1.69, p<.05, d>.20 ) for the float and top spin serves respectively but for shorter durations per fixation (1.62 ± 0.27 versus 1.76 ± 0.29 sec (float) and 1.56 ± 0.32 versus 1.73 ± 0.28 sec (top spin) p<.05, d>.20 ) than the female athletes. These results and findings suggests that Advanced athletes for both serves attended to the most appropriate visual information through the top-down approach, their knowledge and past experiences. For gender differences, the results show that the female athletes employed fewer fixation points in receiving float serves, however the employment of fewer fixation points during the top spin jump serves was due to receiving serves characterised by easily identifiable trajectories and lower speeds. The contradicting finding of the Advanced athletes employing more fixation points for the top spin jump serve may be due to task complexity demands. Thirteen areas of interests were also identified. The combined results for both gender and advancement levels suggest that the athletes fixated on similar areas of interests, primarily the upper body and secondary on the ball (flight), serve reception phase, arrival at target and contact point. The aim and objectives of this study were achieved in that both absolute and relative values for number of fixations, duration of fixations and areas of interest fixated on, were established. However the outcome of comparisons made, were not all expected particularly that of the Advanced group for the top spin jump serve. Possible explanations were offered, but further research is required in this regard.

L'interaction corporelle, une sémiotricité de la communication motrice : analyse de trois contextes praxiques en volleyball / Body interaction, a motor semiotic of communication : analysis of three praxis contexts in voleyball

Ghannouchi Ben Salem, Neila 28 September 2016 (has links)
La présente recherche traite des mécanismes de communication de type praxique qui sont au cœur des interactions ludomotrices qui se nouent au sein de la pratique du volleyball. Cette perspective de recherche offre la possibilité de mieux appréhender et comprendre les conduites motrices des joueurs qui se façonnent dans un réseau sociomoteur s’articulant autour de rapports de coopération et d’opposition. De là, il nous a semblé intéressant d’étudier le contenu du volleyball qui se pratique aussi bien dans le milieu professionnel qu’à l’école. Le réseau de communication mixte de ce sport est bâti sur la trame de comportements moteurs observables des pratiquants dont l’aisance et l’efficacité motrices espérées s’acquièrent au fil des séances d’entraînements conduits par les entraîneurs/enseignants. Dans ce contexte, l’approche techniciste et classique du Volleyball est-elle privilégiée à l’approche « sémiotrice » fondée sur la lecture des conduites motrices des pratiquants et sur la communication praxique ? La recherche de l’efficacité en situation de match accentue-t-elle cette tendance auprès des éducateurs et des joueurs sur le plan de leurs représentations ? Pour répondre à ces interrogations et mettre en évidence ce réseau subtil d’interactions motrices, nous avons analysé des matchs chez trois populations issues du sport de haut niveau, d’association sportive scolaire et en éducation physique à l’école. Ces observations ont été croisées avec des entretiens semi-directifs réalisés auprès des joueurs et des éducateurs et avec un questionnaire reposant sur la procédure de Condorcet. Les résultats ont révélé d’une part qu’au sein du sport de haut niveau les rapports d’interactions motrices des joueurs se fondent sur des réseaux de communications praxiques plus riches qu’au sein du volleyball scolaire et associatif, mettant en valeur des rapports d’opposition et de coopération autour de sous-rôles sociomoteurs variés et privilégiés. D’autre part, le niveau de pratique à l’échelle scolaire, observé dans le contenu des séances menées par les enseignants, privilégie l’aspect technique et physique du volleyball. Par ailleurs, on relève des distinctions quant aux représentations des pratiquants et de la part de leurs entraîneurs et ce, dans les trois populations comparées : pour les pratiquants, l’intérêt porte principalement sur les aspects techniques, tactiques et physiques. Quant aux entraîneurs, outre les aspects techniques et tactiques, l’organisation et la planification de l’entraînement sont valorisés pour atteindre les objectifs visés. La sportivisation des pratiques telles que le préconisent depuis longtemps les finalités éducatives des instructions officielles (1990) en Tunisie, et observées ici, ne facilite pas la mise en œuvre pédagogique et didactique du volleyball dans une perspective sémiotrice. La référence sportive fondée sur des habiletés motrices (techniques corporelles) du volleyball ne fait qu’entraver la réussite des échanges praxiques entre les élèves. Nous nous proposons ainsi de construire une approche originale de l’enseignement du volleyball scolaire sous l’angle d’un apprentissage fondé principalement sur la sémiotricité. / This study deals with praxis communication mechanisms that are at the heart of motor playfulness interactions that are formed in the practice of volleyball. This research perspective offers the opportunity to better grasp and understand the motor behavior of players that are shaping a social motor skills network revolving around cooperative and adversarial. From there, it seemed interesting to study the content of practicing volleyball both high level and at school. The joint communication network of sport is built on the frame of observable motor behavior of practitioners whose ease and hoped drive efficiency gain over the trainings sessions led by trainers / teachers. In this context, is the technocratic and traditional approach of Volleyball is preferred over the approach motor semiotic based on the studyof motor behavior of practitioners and the praxis communication? The search for efficiency in game situations accentuates this trend with educators and players in terms of their representations? To answer these questions and highlight the subtle network of motor interactions, we analyzed the matches of three populations from high-level sport, school sports association and physical education at school. These observations were crossed with semi-structured interviews with players and educators with a questionnaire based on Condorcet Method. Results revealed that within high level sports, motor interactions of players are based on praxis communication networks are richer within school and club volleyball, thus highlighting links of opposition and cooperation around diverse and under-privileged social motor skills roles. On the other hand, the level of practice at the school level, observed in the content of the sessions conducted by teachers, emphasizes the technical and physical aspects of volleyball. Furthermore, we note distinctions as to the representations and practitioners from their coaches and within three populations: for the first, mainly the focus is on the technical, tactical and physical aspect. As for the second category, in addition to technical and tactical aspects, organization and training of planning are emphasized to achieve objectives. The sportization practices such as have long advocated the educational purposes of official instructions (1990) in Tunisia, observed here, do not make easy the educational and teaching work in a volleyball motor semiotic perspective. Sports reference based on motor skills (body techniques) volleyball only hinder the success of praxis exchanges between students. We thus propose to build an original approach to teach school volleyball in terms of learning based primarily on motor skills semiotic.

Uso de apoio tecnológico para scout como instrumento de melhoria de rendimento em equipes de voleibol /

Calixto, José. January 2016 (has links)
Orientador: Adriane de Souza Beatriz Serapião / Banca: Cynthia Yukiko Hiraga / Banca: Alaercio Perotti Júnior / Resumo: O voleibol é uma das modalidades que mais se popularizou no Brasil. Nessa premissa, destacamos aqui a descrição dos fundamentos do voleibol e a as tecnologias aplicadas a essa modalidade, além da utilização de um conjunto de planilhas eletrônicas (em Excel) customizadas para análises técnicas e táticas e para verificação de que as estatísticas geradas pelas planilhas são relevantes para atletas e comissão técnica. Foram elaborados e aplicados dois questionários, um para técnicos e outro para atletas, com 10 perguntas cada um, para avaliar a importância da estatística na visão dos entrevistados. Participaram do estudo 8 técnicos e 89 atletas de voleibol acima de 18 anos, do sexo masculino, nos Jogos Abertos de 2015. Diante das respostas, constatou-se a importância dada pelos entrevistados à estatística nos jogos e treinamentos da própria equipe e das equipes adversárias, melhorando rendimento e sendo determinante para se vencer uma partida, embora nenhuma das equipes entrevistadas possua uma pessoa exclusiva para a coleta dos dados, justificando a falta de profissionais qualificados e alto custo de softwares e equipamentos específicos para essa atividade. Após a coleta dos dados, através de filmagem dos jogos, os mesmos foram visualizados por uma tela de televisão e notebooks para que o pesquisador atribuísse a pontuação para a ação de cada jogador, transcritos e levados para discussão, avaliação e análises. Cada pontuação foi inserida em planilha eletrônica (Excel) customizada para esse fim. As análises técnicas e táticas (estatísticas do jogo) das equipes de Araras e Monte Aprazível, campeã do evento, apresentaram as falhas e eficiências nos fundamentos entre outras informações gráficas que permitiram a visualização de rendimento em cada set, posicionamento tático em quadra e direcionamento de saque ...

On This premise, we emphasize here the description of volleyball fundamentals and technologies applied for this modality, beyond of the use of a series of spreadsheets (Excel) customized for technical and tactical analysis and verification of the statistics generated by spreadsheets that are relevant to athletes and coaching staff. Were created and applied two questionnaires, one for technicians and another for athletes, with 10 questions each, to evaluate the importance of statistics in the interviewees vision. 8 technicians and 89 volleyball athletes with over of 18 years, male, in the Open Games 2015 participated in this study. With the responses exposed, there was the importance given by respondents to statistical games and training the team itself and the opposing teams, improving performance and being decisive to win a match, although none of the teams had interviewed an exclusive person for this job, justifying the lack of qualified professionals and high cost of specific software and equipment for this activity. After collecting the data, through filming of games, they were viewed by a television screen and notebooks so that the researcher attributed the score for the action of each player, transcribed and taken for discussion, evaluation and analysis. Each score was entered in a spreadsheet (Excel) customized for this purpose. The technical and tactical analysis (game stats) teams of Araras and Monte Aprazivel, that was winner in this tournament, showed the failures and efficiencies in the fundamentals and anothers graphical information that allowed the measure the performance in each set, tactical positioning on the court, direction of serve and attacking each of player, supporting and structuring training and matches by importance, ease of interpretation of the data issued by the spreadsheet scout / Mestre
