As atividades de demonstração e a teoria de Vigotski: um motor elétrico de fácil construção e de baixo custo

The experimental demonstration is one of the traditional activities used in the ambit of the Science teaching and of the scientific divulgation. However, this activity has not been fully explored yet in the classroom, because teachers have faced considerable difficulties due to the lack of demonstration equipment. In this work we present the explanation of an easy and low-cost assembly of an electric motor, to be used in Physics classes in High School. In addition, we employed Vigotski’s theory to guide this experimental activity in the classroom.

Presents and discusses the difficulties and feasibility to include the blind for birth student in thermology’ classes. Through content analysis identifies four classes of functioning implies difficulties and feasibility. In conclusion, emphasizes the importance of creating appropriate communication environments, the inclusive function of element interactivity, as well as the need for dismissal of a segregated environment within the classroom.

Grupo de estudo/discussão como estratégia formadora de autonomia docente em professores de física

This work is intended to promote a reflection about the forms of work in groups for continuous training of teachers. Based on the hypothesis that the groups of study / discussion of specific topics in physics can have very effects significant and recommended by the literature, we based on the propositions of the educator José Contreras Domingo about autonomy of teachers and we does a report of an experience with group of continuing education in which they succeeded in developing the characteristics of autonomy of teachers in a job with physics teachers who participate in a group of study / discussion of topics of Modern and Contemporary Physics. In this way presents arguments relating the autonomy of teachers with the teacher continuing education and presents the report of a group of training teachers of physics who works along these lines.

Ação comunicativa na organização do primeiro encontro de ex-alunos de licenciatura em física

In this paper, we aim to understand the discourses of public school teachers who were former students of an Undergraduate Physics Education course, when they are perceived as actors speakers a public sphere concerned about teacher eduaction. So, we focused virtual dialogues occurred between these former students and a professor of the same course during the organization of the First Meeting of Ex-students inserted in an annual event called Meeting of the Teaching Practice in Physics of Ilha Solteira (ENPEFIS). Thus, we analyze these dialogues according to concepts of public sphere, communicative action and teachers as intellectuals according to elements of the content analysis of these virtual dialogues. Therefore, we envision in this work an important discussion for science teaching , since it reflects briefly on Physics Education committed to discussing science teaching in order to overcome the dogmatic and instrumental science education.

Saberes docentes mobilizados por futuros professores de Física em processos interativos discursivos

This research deals with teachers’ education, discussing elements related to the teachers’ knowledge and discursive interaction. Teaching knowledge can be mobilized in different situations and spaces; however, here, we considered them in the classroom environment and the interactive context among teacher-students and students-students. We analyzed the discursive interactions in a 23 future high school physics teachers sample, observed during the development of activities of supervised teaching, in an undergraduate teachers’ initial education program, in one of the São Paulo State universities, in Brazil. The main research question was: which teachers’ knowledge is mobilized by future high physics teachers during the interactive discursive context aiming the construction of scientific knowledge by students? Data showed that in the communicative interaction process in the classroom the student-teachers mobilized teaching knowledge related to the content and to its pedagogy.

Aprendizagem significativa do conceito de ressonância

In this research work we verified the interaction between teacher and students through the use of reading an alternative text, the use of an experimental activity demonstration and presentation of videos involving the concept of resonance in a room on the 3rd year of teaching medium, led to meaningful learning of that concept. The instruments for the creation of data were based on audio and video records, taken during the lecture and the written evaluations performed by the students two weeks later. The results showed that this interaction, mediated by the use of these resources, led to meaningful learning of the concept of resonance. It was also possible to observe the students' motivation to participate actively in class.

Determinação do teor alcoólico da cachaça: uma abordagem das propriedades intensivas

The Resolution number 3 of the Câmara de Educação Básica (CEB)/Conselho Nacional de Educação (CNE), published in 1998, June 26 (BRASIL, 1998), which established the National Curriculum Guidelines for High School Education, emphasizes the interdisciplinarity, in its 8th Article. However, almost fourteen years later, the reality in most of our schools is the adoption of a merely disciplinary methodology, vis-à-vis the difficulty related to educational planning activities of this kind. In this paper, we present a proposal of an interdisciplinary experimental activity that addresses the concept of surface tension, connecting physicists and chemists. The idea is that students determine the alcohol content of “cachaça” and discuss the concepts of surface tension forces between equal molecules, similar and different.

A afinidade com a Física: uma análise feita com estudantes da Universidade Federal de Mato Grosso do Sul (UFMS)

The aim of this study is to investigate aspects that influenced students of Physics at the Federal University of Mato Grosso do Sul (UFMS) to choose that course and the influence that their own teachers had on their decision. In order to do that, a questionnaire was prepared and answered by forty-five students of Physics (bachelor's course or teacher's course). In the results we highlighted that those students developed affinities with physics knowledge before choosing the course. The analysis suggests that the teacher, although not predominant in these choices, is an important catalyst, thus influencing students to choose a career in science co-operating.

Determinação de sacarose no xarope artificial de groselha por medidas de viscosidade: uma abordagem interdisciplinar

The development of the National Curriculum Parameters for High School (PCN) is established from a logic in which the disciplines are integrated and coordinated in order to promote interdisciplinarity. However, there are few didactic-pedagogic activities that enable teachers in practice to reach this goal. In this paper, we propose an experimental activity to be used with High School students, addressing the concept of viscosity from an interdisciplinary perspective between the disciplines of Physics and Chemistry. For that purpose, flow times of sucrose solutions of different concentrations will be measured in a glass Ford and these data will be used to construct a calibration curve, which will be used to determine the concentration of sucrose in artificial flavor syrup of gooseberry.

Função estética dos signos artísticos para promover processos discursivos em sala de aula

The study investigated the use of an artistic work as mediator to trigger and sustain discursive participation of high school students in the classroom. Since the discursive dimension is an essential factor in constructivist teaching orientation, the general idea behind the work seeks to make use of the aesthetic function of signs to enhance the participation of learners discourse. With this goal in mind, the artistic sign painting Water Fall of the artist Maurits Cornelis Escher is employed for teaching physics concept of conservation of mechanical energy. The study compares two methods of a teacher who tries to promote students interactivity discursive. One methodology is guided only by formulating questions and other uses also an artistic sign along with the questions. The work shows that the teacher gets more successfully discursive participation of their students using the second methodology.

Interpretando la estrutura curricular de programas brasileños de licenciatura en Física, a partir de una perspectiva epistemológica de la Didáctica de la Física

This study aims to contribute to understanding the complexity related to the definition and practice of "Didactics of Physics" in initial physics teachers training. We intend to make evident how is understood the Didactics of Physics in curricular organizations, since an "observation" from a perspective based on an analysis of theoretical frameworks of Science Teaching, according to which "Didactics of Physics" is an articulating axis between different disciplines and constitutes the knowledge body to be taught in order to teachers learn to teach physics. For that, we used techniques of documentary analysis, constituting a text from a systematic search of information about Physics teachers’ initial education programs, looking for criteria justifying their organizations and contents of disciplines that aim to contribute to the training for teaching, in a study carried out during 2011. We found on these curricular organizations the presence of disciplines in fields such as: Exact Sciences, Humanities, Social Sciences and Teaching Practice, which indicates a consideration of interdisciplinary training which must receive the future teacher. However, without being consistent with Science Education' epistemology, requesting the integration of interdisciplinary knowledge to solve problems related to teach physics in high school, with some exceptions in the preparation for the subject "traineeship" or training for "Didactic transposition", but since different interpretations.

Aportes teóricos e metodológicos para a constituição de um grupo de planejamento conjunto com docentes da licenciatura em física

We present in this paper parts of the results of a research that had the intention to promote a space of communicative interaction among teachers of an undergraduate Course of Physics Teaching so they could plan their courses together. From the theoretical recommendations of the Theory of Communicative Action , by Jürgen Habermas , it was possible to draw a way of rationality crisis in training degree in physics in Brazil and then propose the creation of a Joint Planning Group (JPG) with teachers of specific nature disciplines of physics and disciplines about physics teaching. They start a joint discussion about the relationship among the disciplines in delivering of a project for future high school teachers' training. All meetings developed over a school year in the GPC were recorded, transcribed and analyzed with a part of a methodological analysis feature of the intersubjective interactions. This methodology was developed specifically for the research. The conclusions are related to the joint constructions developed by the JPG, its local contexts and the possibility of extension of this group. The joint constructions undertaken in the group point to the defense of the formation of JPG in the formation of the professors who teach these courses.
