Efeitos de campos elétrico e magnético em um sistema dissipativo pulsante

The main idea of this work is to understand and analyze the dynamical aspects of the motion of a particle moving in the annular billiard, which corresponds to two circles of radius R and r (rto the particle. Likewise, the collisions with the circles are studied in the conservative (elastic) and dissipative (non-elastic) cases. When we introduce magnetic and electric fields, the particle is submitted to the Lorentz force. It also can suffer successive collisions with the breathing circles, winning or losing energy. For the elastic time-dependent case, we have already observed that a particle can gain unlimited energy. The purpose of this work is to study the effects of both external fields in the mean energy of the system, for the time-dependent case with and without dissipation. Our initial results conduct us to believe that electrical field can contribute to the increasing of mean energy, and a magnetic field applied to the vertical axis of coordinate (what guarantees the particle do not travel away the billiard’s plane) uses to arrest the particle to the whispering gallery orbits and do not contribute to the Fermi acceleration indeed. However, in presence of the electric field, to same values, the magnetic one together can improve this referred process, obtaining greater energy values to the same number of iterations. These results are applied to the concentric case, that was reported did not haven any significant energy gain on the free particle motion

A presença das TIC no curso de licenciatura em matemática da UNESP - campus Guaratinguetá

This research shows an investigation on teaching formation in regards to the TICs. Our interest in this subject is due to the fact that new generations of students who attend school require that the classes make use of technology in the classroom environment. By following the phenomenological orientation we have carried out a study which involved a field research at the College of Engineering in Guaratinguetá using the graduate as well as senior students of the Bachelor's Degree in Mathematics of this university. We have analyzed the data under the light of texts of the following authors: Filho (2007), Valente (1993), Miskulin (2006), Borba and Penteado (2001) among others in order to understand the teacher`s formation process to act using technologies in the classroom and its relevance. The data that has been analyzed was obtained in interviews which were conducted with the students of this university. The interviews were transcribed and analyzed according to the rigor of phenomenological research procedures involving ideographic and nomothetic analysis. This analysis has led us to three open categories: 1) Mathematics learning through TICs; 2) Technologies that have been used; 3) Teacher`s role. By understanding the open categories we have been able to grasp that the students -future teachers- admit feeling capable of using technology in their classes, however their testimonies in regards to the TIC`s have led us to believe that there would be a reproduction of the content studied at their time at college without using further reflection upon the subject or autonomy in order to create new projects for teaching Mathmatics using these TICs

Formação inicial de professores de ciências: reflexões a partir das abordagens das estratégias de ensino e aprendizagem em um curso de licenciatura

We developed a case study aimed to identify and to analyze how the approach to teaching and learning strategies occurs in a science teaching degree course and what are the possible influences of this formation on the pedagogical practice of these educators. The analysis focused on documents, questionnaires and interviews with lecturers and students. There is reduced diversity of strategies in the disciplines of the specific area, with prevalence of expository classes and of laboratory, and the lecturers seem to believe that a good knowledge of specific content is enough for teaching. Despite that pedagogical disciplines do explore diverse practices, many students incorporate the academic view prevailing in the course, repeating the model of their lecturers. We stress the need for initial teacher training to take into account both aspects, the domain of the specific contents and the best ways to mediate them, forming intellectuals able to discuss and to redraw their educative actions in a perspective of transformation of the reality.

A questão da colonização no Brasil: historiografia e documentos

In this article we draw attention to the fact that the documentation relating to the decision to colonize Brazil, as well as the early stages of colonization, comprising two interpretations about the reasons to occupy, populate and organize the production on American soil. The Brazilian historiography joined the explanation of that pressure from European nations led to the Portuguese crown decided on an occupation more effectively. But without ignoring this reason, the documentation allows to take into account their own historical circumstances created by the development of trade. These are essential conditions for the emergence and effectiveness of the proposal to colonize Brazil. Thus, when considering only the pressure of European nations the Brazilian historiography remained on the surface of events. It’s necessary to take into account the documentation on what it allows to grasp the colonial process as a historical phenomenon and not just as an act of will.

A formação de docentes inclusivos: um desafio para a educação brasileira

Respect for differences is one of the most important subjects in debate in the Brazilian and World society today. It’s consensus that diversity education is very important to make humanity fairer and more equal. In this context, it’s necessary to separate real pedagogic actions from political demagogy. So, our objective in this paper is to enrich this discussion with the results of our project “Perspectives of teachers about the inclusion of special students in Programa UNESP de Educação de Jovens e Adultos”. These results will demonstrate a good example of inclusive education and will prove the inadequacy of training in special education offered to Brazilian university students. In our opinion, it’s impossible to believe in diversity education without appropriate training in inclusive education because this work requires accommodation of social, political, physical, religious, cognitive and cultural differences and this demands a skilled professional in all teaching methods.

O lúdico no desenvolvimento infantil: um estudo teórico

It is a fact that childhood is a period of play and it is through them that the child meets their interests, express their way to organize, disorganize, build, think, making new discoveries. Therefore, the playful stands as one of the most important and effective in children's learning process forms, as it enables the development of imagination, feelings and fantasies, helping the child progress in their motor, psychomotor, cognitive, and physical skills emotional. This gives her the exercise of attention and memory to play activities adults engage, thus expanding their knowledge about the world. The teacher's role in this process is essential, where it can bring to everyday life of the child in various situations themes, turning the simple play on continuous learning and not just using the play as a complementary activity to the child because they provide pleasure and relaxation which do interact with the new learning and the group operates. The psychology emphasizes that play is essential to the balanced development of the psychosocial human being, because when in childhood, the relationship with the toy and gaming in general develops affectivity, creativity, and reasoning ability. Playing, the child increases their independence by building their knowledge. The aim of this work is to make a theoretical study based on a literature search, aiming to understand the play within the child development process, where it is recognized as very important in a child's learning starting from the theoretical conceptions of thinkers such as Piaget, Vygotsky, Wallon among others. With this, it can also be possible to recover the importance of the play that is being extracted from the infant universe due to new reasons to experience the modern world brings, as the excess number of activities assigned to the child, electronic games, etc. Finally, a playful approach to provide a reflection for parents and educators, bringing children's learning...

História da comunicação social: um campo em construção

Not intending to exhaust the subject, we will attempt to show the issue status in the construction of the History of Mass Media. An initial literature review, in order to identify works relating to the subject, shows us how this issue has gone unnoticed in Academy. Expert authors in the history of every media outlet (newspaper, radio, television, movies, and more recently, internet) have been rising, but few have faced the challenge of building a History of Media. There are many reasons to justify this. It comes from the fact it is a young science, in construction, to the absence of a clear definition regarding the subject matter, sources, and methods of their own area of expertise. After all, journalism and film, for example, can be inserted in the same methodological procedure?

Nível de atividade física e imagem corporal de alunos ingressos de um curso de educação física da Cidade de Santo André - SP

The aim of this study was to evaluate the level of physical activity confronting to the real and ideal body image of 65 individuals of both gender (27 women and 38 men) aged between 18 and 37 years old, all students of a Physical Education College of Santo André´s City - SP. The instruments used were the International Physical Activity Questionnaire, Short version (IPAQ, 2005) and Test for assessment of Body Image proposed by Stunkard et al., (1983) and adapted by Marsh and Roche (1996). According to the results, male subjects are more actives compared with female, as well as for the real and ideal body image males showed no significant difference, however, the females showed differences between the real and the ideal body image, between the gender no significant differences existed on the real and ideal body image. We can conclude that the students of this Physical Education College mostly presents in moderate or high level of physical activity, showing that the male are pleased with the real and ideal body image, and for a willing female body silhouette thinner ideal than real, with no significant differences between genders, and thus leading us to believe that the physical education College lead the students to experience practical activities becoming them lifestyle most active in search of a better quality of life and wellness.
