O tratamento probabilístico da teoria cinética de colisões em livros de química brasileiros para o ensino médio

This paper presents and discusses an analysis of the approaches and the didactic treatment of the kinetic model of collision between particles in chemical reaction (collision theory model) presented by brazilian chemistry textbooks for the medium level. Our starting point at this search was the correct and scientific model for this theory which is based on random events, but most of all the books investigated does not consider this fact like an important and very precious didactic aspect. We utilized in the investigation the writing discoursive analysis technique.

Iniciação científica e formação de professores: breve relato de uma experiência

A revista em que este artigo está publicado foi distribuida no final de abril de 2011, mas vem com data e registros duplicados - um recurso empregado para acertar a periodicidade. Assim, o mesmo e único fascículo contem o número 04 (volume 2) e o número 5 (volume 3), o primeiro referente a julho/dezembro de 2009 e o segundo referente a janeiro/junho de 2010. Neste registro do Lattes indico o ano da produção como sendo 2011 posto que este artigo não constou de nenhum dos relatórios relativos a 2010.

Abordagem experimental da força de atrito em aulas de Física do Ensino Médio

In this paper we propose and describe the performance of an experimental activity to address the concept of friction in High School Physics practical classes. We use a low-cost and simple construction device that enables the determination of the coefficient of static friction between two materials through three different procedures. The results were coherent, with small percentage deviation, which gives reliability to the activity and can stimulate discussions in class. The activity also allows greater contextualization of concepts that are usually discussed only theoretically, requiring a higher abstraction level of the students. This can stimulate discussions and greater interaction between teacher and students.

Física Moderna no Ensino Médio: um experimento para abordar o efeito fotoelétrico

Considering the importance of the inclusion of Modern and Contemporary Physics in the curriculum of Physics in High School, it is proposed in this work an experimental activity, made with low- cost materials, which presents the photoelectric effect. This activity can be used articulating this phenomenon with some technological applications experienced by the students in their daily lives. When working the experiment, the teacher can encourage students to investigate what happens during its execution and, through questions, get them to express their ideas in the previous attempt to explain its operation. This articulation linked to social interaction in the classroom can arouse the students’curiosity and motivation of students to learn the subject taught in classroom.

Cartografias contemporâneas: mapa e mapeamento como metáforas para a pesquisa sobre a formação de professores de Matemática

This essay sketches some principles according to which a research project called “Mapping of math teacher education and practice in Brazil” is been conducted by a group of researchers with the objective of understanding the way policies related to teacher education and practice are effectively implemented in different regions of the country. The main objective of this article is, therefore, to discuss the pressupositions of this project, its foundation, the basic beliefs in which it is rooted. In order to emphasize such principles, some remarks on theorization, methodology, teacher education, narratives and on the concept of mobilization/apropriation are done. The essay is based on a metaphor built on cartographical practices.

Representatividade das redes sociais no processo educacional: potencialidades dos grupos virtuais como ferramentas de ensino-aprendizagem no Ensino Médio

One tool that has been in evidence, especially among young people, is Facebook. It can be classified as a synchronous communication tool that allows communities of people with similar interests to discuss and exchange experiences in real time, promoting the sharing of information and the creation of collective knowledge, even if they being in different parts of the globe. In this paper we show that Facebook can be used as an educational tool to aid the work done in the classroom and the impact of creating closed groups in online social networking for educational purposes. The survey was conducted with a group of students at a private school in Bauru/SP. We investigated the interaction profile of students with a closed group created on Facebook and through a questionnaire analyzed whether students use virtual environments for personal or educational. The survey reveals students perceptions about relevant aspects and the potential use of this tool as teaching-learning strategy

Prática como componente Curricular e estágio supervisionado na formação de professores de Educação Física

This study aims to investigate the main issues presented in the literature relating to teacher training during the period 2005/2014. Particular attention is paid to articles that address the Supervised Training and Practice as a Curriculum Component. For the analysis of the articles from the literature, the technique of Content Analysis was used. The results showed that the potential which is attributed to these curricular components depends on the ability to put the trainee teacher in touch with the experience of being a teacher, whilst enabling the approach of the training content to be consistent with professional practice. The technical and fragmented curriculum for training and the extensive content in the disciplines, limited by outmoded practices, is presented as a barrier against this occurring. This shows a discrepancy in the proposed training between the pedagogical design of the course and, what is actually designed as concrete action in its development.
