Energy is a physical quantity very present in physics. Although extremely useful, its concept is very abstract for most students in high school and college. Identify the presence and form of energy in a given phenomenon is not simple, as there is immediate understanding on the transfer and transformation. This work emphasizes the study of mechanical energy in its different forms as well as the thermal energy, considering the possible transformations between them. To this end, use is mad of toys, exploring its potential as an alternative material to be use in supplement classroom teaching in primary and secondary levels. The proposed use of ludic pedagogy takes into account the author’s experience as an intern project Toy Scientific Department of Physics and its role as mediator in the workshops offered by the project to school at these levels

Circus activities have formed over the years as an important content to be exploited by the teachers in the school environment, and current projections, the inclusion of circus activities in physical education classes has been presented and defended by several authors. That being so, the objective was to offer a continuing education program thematising circus activities having as research focused on the analysis of this training process, as well as their implications, contributions, opportunities and challenges for teacher pedagogical practice. The research, qualitative, was developed in two phases: a questionnaire for physical education teachers working in public schools in order to highlight the reasons for the absence of most of the teachers in the training program. The second phase included the development of the continuing education program content circus activities in the continuing education of physical education teachers, the two teachers in the school environment, as well as analysis and reflection of teacher participation in the training program, described in daily class and daily meetings ending this step with a final interview. Participated in the study, 13 physical education teachers of the municipal school system of a city of São Paulo, of which only two teachers participated in the development of the training program in schools. The teachers manifestations through the questionnaire and participation in the training program showed that teachers make themselves available to participate in continuing education programs, however, the priorities of each teacher (such as family, leisure or other chores) can demarcate difficulties in establishing common to all teachers moments, preventing the effective participation of teachers within the continuing education programs. On the other hand, the school is set up as a rich space of experiences and exchanges of experience, contributing to the development of continuing education programs

This research is a short article about urban dances in Brazil, about how did it came and became popular here, and also it will discuss about the different nomenclatures that exists nowadays: street dance, dances from street or urban dances. As a bibliographic reference, a research was made about the history of those dances in an international context, the creators and all the elements that consists the Hip hop culture: Break dance, grafitte, MC and DJ. The research methodology is characterized as a qualitative, it search for information that can be deeply studded, and the method used was history telling, which prize and brings up the man memory of the facts. The interview was also used as a tool in a previously elaborated script with open questions, so the interviewees could answer their own way and talk as much as they need about the issue. The analyze was made using the Bardin (2009) method. The interviewees are very important at the Hip Hop scenario because their lives were dedicated to the research about urban dances and the Hip Hop culture. During the interview they told how they started to dance and that their first contact with urban dances was made by watching movies that came to Brazil in the eighties. Michael Jackson has also contributed to spread this urban dances at that time with his videos. The main goal of this research is to tell the history of the urban dances, how did they got here, who brought it and how it has spread in Brazil. It justify itself during the fact that exists just a few researches in a scientific way that study this issue, thus the history importance that this contents is to the urban dances in Brazil. My conclusion of this article is that the history has many different ways, a lot of names, and that the urban dances in Brazil has began in many different places at the same time, by films influence that has promoted the styles that had came here in the eighties

Exercise, in general have the ability to promote health, reduce loss of physical fitness, reduce declines in body composition and prevent disease, and promote improvements in athletic performance, and that's consensual today. Through analysis of body composition and physical fitness, you can diagnose the possible individuals at risk of developing diseases, and fractures caused by falls in the elderly. The DXA tests were used (densitometry by dual beam X-ray) to assess body composition and regional, 1 RM test to evaluate the maximum strength and girth measurements, diameters and skin folds in order to analyze the balance of power muscle with both body composition as regional. The results showed that the variance in bone mass between older content related to the change in the maximum muscular strength of the upper and lower limbs, but the force values are not related to increased muscle mass. The development of muscle strength fulfills a dual function in aging which is to maintain or reduce the rate of loss of lean body mass, and also so the body bone health

Childhood is a theme that has attracted many controversies and discussions, and winning approaches to the increasingly large over time: biological, psychological, educational, welfare and, more recently, sociological. It is known that the movement, play and game activities are important recurrent and integral development of children, and should be present prominently in early childhood institutions. Based on these assumptions is that this study aimed to analyze the didactic-pedagogical principles postulated by the law, official guidelines didactic teaching and literature, with regard to meeting the needs of children in early childhood education. Unveiling the expectations of the families responsible for children in relation to early childhood education, especially with regard to movement, and play games and compare to what extent these expectations turn away or close to the guidelines on teaching and pedagogical movement, games and postulated in official documents, legislation and literature. To this end, we carried out literature search, selection and analysis of texts relevant to the understanding of the theme. Fieldwork was conducted in a Municipal School of Early Childhood Education Full-time (Emei) of Bauru/SP, and involved the analysis of the Political-Pedagogical Project of the institution, semi-structured interviews with five teachers and five children in the family responsible for Garden II (ages 5 to 6 years). Data were analyzed using thematic content analysis of Bardin and triangulated by the confrontation of literature/legislation, the Pedagogical Political Project of the institution and the expectations of families/guardians. We also realize that the Pedagogical Political Project of EMEI is in routine activities with the children, movement, and play the game are covered and are worked. According to teachers interviewed they assist in learning other areas of work (Oral and Written Language, Nature and Society, etc.) learning of moral...

Sports team, specifically soccer and handball, has traditionally composing the physical education school contents as a curriculum component. There are several criticisms to extend this approach beyond the sportive discourse. While we recognize this need for expansion, we believe that the methodological endeavors to teach these sports content are still very poor, requiring, therefore, studies that guide us in changing not only contents but also the way of teaching it, which implies new e teaching, pupils and teaching relationship perspective. In this sense, the objective of this study was to identify and analyze, from a sports team tactics teaching approaches of invasion, the demonstrations by students, the phases of handball and soccer games, as well as the elements/dynamic structural, functional and operational in the same school environment. Given this objective, qualitative research, specifically, collaborative action research, best meets investigation is this scenario, since classroom teacher and students also participated in the content construction and strategies undertaken during the intervention. The study enrolled 28 students in the fifth grade, aging 10 to 11 years, in a Bauru/SP public school, physical education teacher and the researcher. Were planned and taught together, 14 classes over a semester with the handball and futsal content, guided for teaching tactics approaches. The data collections were made through systematic lessons observation (through filming and recording diary), interviews with students and descriptive reports made by the classroom teacher and researcher. The results indicate that there was an improvement in the phases of soccer and handball game, even though only the latter has changed its category phase to decentralized anarchic phase. Several students showed in the situational interviews, a more elaborate game understanding than the one identified in the game demonstration. In the analysis of relationship levels..

Swimming is a sport well suited to any age group, it worked properly when the individual stimuli that provides assist in human development. But water stimulation, is not something that is so easily in physical education in Brazil. Development corresponds to changes that occur throughout life, but that depends on the stimuli provided. Several studies have shown positive effects of swimming in relation to the child. This study aimed to verify if children swimmers and physical education classes have better motor development than those who do not practice the sport. Collection was done with two groups of 10 students between 9 and 11 years. As a group consisting of non-swimmers, and another formed by those that complement the physical education class with the regular practice of swimming. To develop the study was administered a battery of the proposed motor adapted Rosa Neto (2002) in which each child performed tasks corresponding to their chronological age (CA) and were only able to perform the task at a later age, when it was obtained successful in completing the task as originally proposed. At the end of the application of all statistical tests was done getting mean and standard deviation of the old motor (IM), calculated the ratio General Motor (MGQ) for the classification of the child's motor development and application of the t test with p <0.05 to observe the level of significance in the results. The results showed that the group swimmers had better agility tests which resulted in a difference between (IC) and (IM) higher compared with the non-practitioner. They also had higher average (MGQ), but these were not sufficient to classify the group into another level of development, however, by observing isolated cases, two children that practice would be a greater level of development. Through the t test was observed that the group swimmers had significant difference in balance ability. We conclude that the swimming group got positive overall...

The control of stances such as the upright stance seems not to have a purpose in itself; this control could facilitate the execution of other simultaneous tasks, the so-called suprapostural tasks. The goal of this study was to determine the effects of saccadic eye movements on the control of posture. Twelve adult participants had their body oscillations analyzed while standing upright, for 70 s, in the postural conditions of feet apart and feet together, performing fixation in the central target or horizontal saccadic movements, in the conditions slow (0,5 Hz) and fast (1,1 Hz). The results showed that saccadic movements, independently of their frequency, strongly reduced trunk and head oscillations in the anterior-posterior (AP) axis. In this axis, there was an effect of feet position only in head oscillation. In the medio-lateral (ML) axis, the results showed a strong effect of feet position with body oscillation decreased in the condition of feet apart. The effect of the visual task in the ML axis occurred only for trunk oscillation, not reaching significance level in the pairewise comparisons. In the AP axis, the data corroborate a facilitatory explanation of the control of posture: the reduction in body oscillation limited the variations of the stimulus image projected on the retina, facilitating the execution of saccadic movements as compared to fixation. In the ML axis, the effect of reducing the basis of support was more evident than the effect of saccadic movements, suggesting that the available resources were used primarily for the postural task in detriment of the visual task. Additionally, aspects like attentional focus and sensory information pick up are discussed as mechanisms involved in this task

The purpose of the present study was to analyze the visual control of braking a bicycle when the cyclist is surprised by an obstacle in his way. According to Lee (1976), visually controlled braking based on time to collision information utilizes the optic variables tau and its first derivative in time, tau-dot, to initiating the braking action and regulating its intensity. Seven young adults performed a bicycle braking task in curvilinear trajectory under distinct velocity (high, medium, and low) and uncertainty (certainty and uncertainty) conditions. Results showed that, independently of velocity and uncertainty levels, participants utilized tau and tau-dot to initiating and regulating the braking action, avoiding collision with the obstacle. Cognitive, attentional, and other psychological factors resulting from both increased velocity and uncertainty were not capable of altering the use of time to collision information, corroborating the tested hypothesis

Physical education in their school environment can contribute positively in the training of students as it is in this discipline that many students feel more motivated to discuss and reflect on conflicts related to school life or in society. In this study we treat the rugby exploring attitudes and values that are present in this sport, considered important for the development of the student, with the methodological approach the dimensions of the contents developed by Coll et al. (2000) and Zabala (1998). Thus, the aim of this study was to develop rugby content emphasizing the values linked to it with students of the 5th year of primary education in a public school in the city of Rio Claro / SP. Among the values are integrity, passion, solidarity, discipline and respect that will be developed through conceptual and procedural lessons about rugby and its educational values, also taking advantage of situations up to during classes for discussions. The survey was conducted for 3 months. The evaluation was by holding a tournament organized by the students and by the researcher to observe what they learned regarding the dimensions of rugby contents (conceptual, Procedural and Attitudinal) and an essay where students expressed the experiences. As a result we see the importance of working educational values in society and the implementation of educational sports at school as a motivational tool. With the contribution of this research, it is expected that rugby can be worked in schools as an educational sport for the training of the individual and the development of physical culture of the students

Sabe-se que o atletismo vem sendo pouco ensinado nas aulas de Educação Física das escolas brasileiras, dadas justificativas tais como: falta de materiais e de espaço, falta de interesse dos alunos ou o fato do professor não saber como ensiná-lo. Pensando em formas para motivar o ensino do atletismo na escola, verificamos a possibilidade de utilização de videogames, já que, desde os mais antigos, o atletismo tem aparecido com uma das modalidades esportivas que podem ser jogadas virtualmente. Nesse sentido, o objetivo dessa pesquisa foi identificar os jogos de videogames relacionados ao atletismo, analisando, em um deles, isto é, no Kinect Sports (Xbox 360), as proximidades e distanciamentos em relação à modalidade esportiva oficial, a fim de se verificar suas possibilidades pedagógicas. A análise deste videogame revelou que este possui características que podem ajudar o professor no ensino do atletismo, já que aborda algumas de suas regras e movimentos específicos, particularmente, da corrida de velocidade, lançamento do dardo, salto em distância, lançamento do disco e corrida com barreiras. Entretanto, o videogame apresenta fragilidades em relação as características antes apontadas, as quais merecem ser realçadas pelo professor de Educação Física em suas aulas. Conclui-se, portanto, que são várias as possibilidades pedagógicas deste jogo de videogame para o ensino do atletismo em aulas de Educação Física, desde que haja uma apropriação devida por parte do professor

O atletismo é uma modalidade esportiva pouco explorada em aulas de Educação Física Escolar. Há muitos motivos para isso, tais como: falta de espaço adequado na escola para que possa ser realizado, falta de material, desinteresse dos alunos e de professores. Em virtude disso, esta pesquisa tem como objetivo investigar as experiências pedagógicas de professores de Educação Física com o atletismo, registradas em vídeos disponibilizados na internet, mais especificamente no Youtube, verificando suas contribuições para o ensino e difusão desta modalidade esportiva na escola. Para tanto, foram coletados vídeos da rede social Youtube, a fim de elaborado um banco de dados sobre o assunto, de forma a auxiliar professores de Educação Física, incentivando-os a divulgarem seu trabalho na internet. Após a análise dos vídeos, foram criadas duas categorias: a primeira denominada Vídeo Amador e a segunda Vídeo semiamador. A partir dessas duas categorias, elaboramos 3 eixos que auxiliaram na obtenção dos resultados, que foram: Eixo 1 - Conteúdo e meios, Eixo 2 - Ambiente e fase escolar e Eixo 3 - Poder de difusão. Ao final das análises os resultados nos mostraram que o atletismo, está de certa forma sendo ensinado no âmbito escolar, mais especificamente nas aulas de Educação Física, mas como evidenciamos no Eixo 3 - Poder de difusão, os vídeos com estas experiências, não estão sendo publicados, mais que isso, não estão sendo visualizados por professores e alunos, a fim de aumentar a difusão do atletismo, tanto quanto, o ensino deste. Concluímos que a partir desta pesquisa possamos fornecer subsídios para que os professores de Educação Física possam construir, junto à escola e aos seus alunos, possibilidades de ensino-aprendizagem em torno desta modalidade esportiva, contribuindo para a sua difusão no âmbito escolar
