O Ensino de ligações químicas por meio do conceito de energia: uma proposta didática para o ensino médio

This work presents discussions on the teaching of Chemical Bonds in high school and some implications of this approach in learning chemistry by students. In general, understanding how the chemicals combine to form substances and compounds, it is a key point for understanding the properties of substances and their structure. In this sense, the chemical bonds represent an extremely important issue, and their knowledge is essential for a better understanding of the changes occurring in our world. Despite these findings, it is observed that the way in which this concept is discussed in chemistry class has contributed, paradoxically, to the emergence of several alternative designs, making the understanding of the subject by students. It is believed that one of the explanations for these observations is the exclusive use of the "octet rule" as an explanatory model for the Chemical Bonds. The use of such a model over time eventually replace chemical principles that gave rise to it, transforming knowledge into a series of uninteresting rituals and even confusing for students. Based on these findings, it is deemed necessary a reformulation in the way to approach this content in the classroom, taking into account especially the fact that the explanations of the formation of substances should be based on the energy concept, which is fundamental to understanding how atoms combine. Thus, the main question of the survey and described here of the following question: Can the development of an explanatory model for the Chemical Bonds in high school based on the concept of energy and without the need to use the "octet rule"? Based on the concepts and methodologies of modeling activity, we sought the development of a teaching model was made through Teaching Units designed to give subsidies to high school teachers to address the chemical bonds through the concept of energy. Through this work it is intended to make the process of teaching and learning of Chemical Bonds content becomes more meaningful to students, developing models that contribute to the learning of this and hence other basic fundamentals of chemistry.

A educação a distância e a formação docente

This study was guided by the following question: Is it possible to prepare good teachers for Basic School in Distance Learning (DL) online? The over all objective of this study was to identify and systematize the essential knowledge and skills for the practice of teaching in basic education as well to investigate whe ther the Distance Learning courses which train and prepare future teachers include all the knowledge and skills necessary for teaching practice. This is a qualitative the oretical and bibliographic research that aims to analyze the current stageof the knowledge on this theme. We selected recent papers on this subject, in order to study what has been written by the authors as well to know which are their significant findings. Data were collected from dissertations, thesis and books published on the theme. Preliminarily, the theme of the presentation and contextualization has been made and the argument about the relevance of the study for education. In the second section, we present an overview of the Distance Education in Brazil: coargumentncepts, characteristics, emergence, evolution and regulation. The third section the working environmentin training teachers and students in on line education, targeting to be familiar to Learning Virtual Environments (LVE), analyzing how these new learning spaces are settled and how students and teachers be have in front of the new settings of teaching and learning using Information and Communication Technologies (ICT). In the fourth section aimed to identify which are the essential knowledges and skills that the teacher must master in order to work competently as well to discover which are the personal and professional characteristics of a good teacher in the XXI century. The fifth section studied and analyzed the current situation with in Distance Education is carried out in Brazil. We identified the most significant contributions of Distance Learning to Brazilian Education System in order to contribute to advances in the debate on the effectiveness of teacher training courses in distance education mode online.Finally in the sixth section were made final remarks and presented the study results.

Uma proposta de ensino de frações no 6º ano do ensino fundamental a partir da teoria histórico-cultural

This text presents developed in the Graduate Program in Science and Mathematics Education at the Federal University of Uberlândia, in which it was intended to answer the question: What are the pedagogical implications for the fractions concept learning for students of the 6th grade of elementary school that the teaching guide activities can provide? The objectives of this research were: a) analyze the possible pedagogical implications for the learning of the fraction's concept for students of the 6th grade of elementary school through guiding teaching activities; b) using the conceptual connections of the fraction to enable students to develop an abstract thought and c) investigate whether guiding teaching activities reflect on 'how to think' and 'how to do' of the student. Five teaching activities have been developed (MOURA, 2002) from the perspective of teaching guiding activity (TGA) and had as object of study the teaching of fractions for students in 6th year of elementary school. They have been prepared and proposed activities in which it was intended to investigate the use of history of mathematics as an aid in learning the conceptual fraction links (CARAÇA, 1951) by students. Such activities, for analysis, were organized into episodes and scenes (MOURA, 2004) and discussed how students deal with the measurement of whole quantity (all) and subunits (part); how they represent in verbal or written language. It is hoped that the research is set up as an important contribution to mathematics teaching area and may contribute to the initial and continuing training of mathematics teacher sand the formation of theoretical thinking of elementary school students.

Formação inicial, profissão docente e competências para a docência: a visão dos futuros professores

No primeiro capítulo – intitulado Formação inicial, profissão docente e competências para a docência: a visão dos futuros professores – investiga-se o que os futuros professores pensam sobre a profissão docente e sobre as competências necessárias ao exercício profissional e identificam-se as suas perceções sobre os contributos da formação inicial (curso de formação pré-Bolonha) na construção de competências profissionais. O estudo seguiu uma linha qualitativa e recorreu a entrevistas semidiretivas para a recolha dos dados. A análise de conteúdo releva a natureza multidimensional da profissão docente; as múltiplas competências pessoais/profissionais necessárias ao exercício da docência, as fragilidades do modelo de formação para dois ciclos de ensino e a fundamental articulação entre os saberes teóricos e a prática profissional. Na verdade, como referimos, a formação dos professores resulta, não apenas da formação inicial, mas sobretudo da socialização do aprendiz de professor enquanto aluno e da socialização pelo trabalho e da interação com os pares.

Formação docente continuada, desenvolvimento de práticas pedagógicas em sala de aula e promoção da saúde do professor: relações necessárias

This article presents an analysis of the results of an action of teacher continuing education in a public Brazilian university. It presents and discusses relations that proved to be necessary between the aforementioned action, the development of classroom pedagogical practices and the promotion of teachers’ health. Its theoretical and methodological foundations consist on a clinic, developmental and dialogic-argumentative character and employ the method of simple and crossed self-confrontation,in order to address professional teaching gestures. The results indicate the necessity of actions related to teachers’ continuing education, focused primarily on the concrete classroom work, which, in addition to allowing the development of pedagogical practices, makes the promotion of teachers’ health itself possible.

Aprendizagem de um gênero de discurso e de atividade de autoconfrontação em ações de formação docente continuada na educação superior

The objective of this text is to discuss a central question in a doctorate study, in progress, about the learning of the speech genre in self-confrontation situations. This consists of a procedure, which a worker observes your own images, video recorded at the time it performs activities related to their craft; It requests that he comment on what he was doing on the images in order to clarify matters for himself and another - be it a intervenant (simple self-confrontation) or a coworker (crossed self-confrotation). (CLOT, 2008/2010). In the context of this research, the confronted workers are university teachers and students who participate in an action of teacher continuing education. The object of the research is the process of speech genre of learning self-confrontation situation, having as subject a person who conducts self-confrontations training, which initially observed the conduct of dialogues and reflections, and will gradually participating in the self-confrontation activity and becoming also forming another. The theoretical foundations of the research seeks an articulation between sciences such as the Psychology of Labor, the Cultural-historical Psychology and Linguistics. The concepts that are employed come from Clot´s theory of the Psychology of Labor, that is, from the Clinic of Activity and from the activity genre studies (CLOT, 2008/2010); they also come from the Vygotskian theory of human development, with the concepts of thinking and speech (VIGOTSKI, 1934/1998); and from the Bakhtinian dialogic principle (BAKHTIN, 1979/2011). We believe that the formation of the person conducting self-confrontation occurs through learning a gender of speech and a genre of activity.

Estilos motivacionais de professores: propriedades psicométricas de um instrumento de avaliação

The purpose of this study was to conduct an exploratory factorial analysis of Problems in School, a teachers' motivational styles evaluation instrument, constructed by Deci et al. The original instrument is in a Likert-scale format with the underlying assumption of the existence of a continuum of four different styles contributing to promote students' autonomy. Translated into portuguese, the instrument was applied to 582 elementary and junior high school teachers from several regions of Brazil. Factorial analyses revealed a solution with four orthogonal distinct factors, the authors' initial supposition (existence of a continuum) was not confirmed. In fact, only two opposite styles (both high promotion of autonomy and of control) corresponded to the Deci et al. original ideas. Problems regarding the validity of the other remaining styles emerged. Data was discussed and a revised version of the scale was developed. Directions for further research were also suggested.
