This paper comprises a case study within the scope of Chemistry teacher training that aimed to analyze the process of professional development progression of a future teacher. Therefore, we sought to identify the didactic models present in the Work Plans developed in primary schools by graduate students during supervised training. To do so, Rafael Porlán Ariza and Ana Garcia Rivero's theoretical foundation about the knowledge evolution of the teacher's professional knowledge was employed. The investigation results made evident that, during the internship period, the teacher progressed to stages deemed to be desirable to the professional development process. Moreover, evidence was found of the relation between the different academic course experiences and the teaching practices employed by the future teacher. Thus, contributions are pointed out for the comprehension about the path of professional development progression of teachers under training.

In this paper we present a brief introduction to the area of Forensic Science and Criminal Investigation, as well as its importance in elucidating crimes. Furthermore, we propose as examples four didactic modules of experimental character (fingerprints, footprints, blood and ballistic), which may promote understanding of phenomena/concepts involved in areas of chemistry, physics and mathematics, and/or can be used in the development of a teaching proposal in the attempt to unravel a fictitious crime in a contextualized and interdisciplinary form. The teacher or responsible for the activity will fit the role of seeking the best way to use these materials within the context of their classes, and the opportunity to discuss with other teachers in order to exchange experiences and thus perceive other forms of application.

En este artículo se presenta una breve introducción al área de la Ciencia Forense e Investigación Criminal, así como su importancia en la elucidación de crímenes. Más aún, se proponen ejemplos de cuatro módulos didácticos de carácter experimental (impresiones digitales, pisadas, sangre y balística), con los cuales puede promoverse la comprensión de fenómenos/conceptos involucrados en estas áreas de la química, la física y las matemáticas, y que pueden ser utilizados para el desarrollo de una propuesta de enseñanza, bajo la misión de resolver un crimen supuesto en una manera contextualizada e interdisciplinaria. El profesor que sea responsable de la actividad deberá jugar el papel de buscar la mejor manera de emplear estos materiales en el contexto del aula y de discutir con otros profesores para intercambiar experiencias y otras formas de aplicación.

Here are presented discussions that took place in an interactive teacher formation group focused on the production and development of a curricular innovation called Study Situation (SS). The aim of the proposal is to break with the traditional teaching model, in which students are seen as static objects that are isolated from their cultural and social environment, with no choice of voice. In order to contribute with overcoming this situation, a research in action process was developed involving teachers and undergraduates at a Brazilian university, and Elementary Education teachers and students to develop the SS: Drugs - effects and consequences in human beings, as well as analyzing its potential and limitations to build an integrated curriculum taking into consideration themes that are socially relevant so as to contribute to improve life quality without overlooking subject contents. The research shows that this way of teaching encourages effective student participation in their learning process, provides a greater production of senses and meanings to the concepts of chemistry, physics and biology, and contributes to establish teachers who research their daily school deeds.

Este artigo apresenta o planejamento e desenvolvimento de um projeto curricular construído enquanto processo, com o intuito de organizar estratégias metodológicas, entre elas a resolução de problemas, e completar, assim, uma proposta pedagógica com pressupostos construtivistas. A pesquisa foi realizada com uma turma de oitava série do Ensino Fundamental, na disciplina de ciências. A participação de um professor pesquisador, capaz de realizar a interlocução entre teoria e prática, e o diálogo entre professora e alunos tornaram-se elementos determinantes para a estruturação do projeto curricular, buscando a abordagem de conceitos científicos ao mesmo tempo em que necessidades e interesses do grupo em estudo pudessem ser debatidos. A interação em sala de aula e as produções dos alunos, a partir das estratégias utilizadas, foram componentes de análise e discussão para direcionar o desenvolvimento da proposta, e modificaram o comportamento e os hábitos dos sujeitos envolvidos no processo.

This paper presents the planning and development of a curricular project built as a process, with the intention of organizing the methodological strategies used, like problem solving, and to fulfill a pedagogic proposal in a constructivist approach. The research was carried out with an eighth year Elementary Education science class. The participation of a teacher-researcher capable of making the interlocution between theory and practice, and the dialogue between teacher and students, turned out to be determining elements to structure the curricular project, searching for a scientific concepts' approach, at the same time that the needs and interests of the group could be discussed. The classroom interaction and the students' productions, from the strategies used, were analysis and discussion components in order to guide the proposal development, and they modified the behavior and habits of the subjects engaged in the process.

O uso da divulgação científica como instrumento pedagógico é o tema de nosso trabalho. Partindo da perspectiva de trazer para a educação em ciências e em química a literatura de divulgação científica (LDC) como um veículo para construção do conhecimento escolar e como alternativa ao livro-texto, apresenta-se neste trabalho a percepção de professores de química do Ensino Superior sobre a sua possibilidade de inserção na prática docente com a finalidade de facultar ao professor em formação o conhecimento deste recurso didático às suas aulas e que isso faça parte do currículo.

This paper focuses on the use of scientific dissemination literature as a pedagogical tool. This study departs from the perspective that the scientific dissemination literature (SDL) can be employed in scientific and chemical education as a means of knowledge construction at school and as an alternative to the didactic textbooks. In this sense, this paper presents the perceptions of chemistry professors on the possibility of employing SDL in teaching. The aim is to provide teachers in training with knowledge of how to use this didactical resource in the classroom, suggesting the inclusion of such knowledge in the teachers' training syllabi.

In this paper we critically analyze a successful case of an introductory Chemistry course at the University of Aveiro, Portugal. Our goal was to identify the main characteristics of the innovations carried out which may tentatively explain the high rate without lowering academic standards. Data collected from different pieces of information were cross analyzed and four characteristics emerged: lectures were organized so as to actively involve students in the learning process; teaching was organized to stimulate the students for the study of Chemistry and also so as to reflect the way Chemistry is done; course coordination ensured an appropriate balance between pedagogical coherence within the group and the individual initiatives of staff members. Overall, these aspects reveal a clear shift from traditional teacher-centered practices to student-centered instruction congruent with constructivist ideas.

The teaching of general chemistry involves both the choice and the organization of its concepts. Although College Teachers make their choices, frequently the text books play an important role in this selection. In the present project we intend to show what are Teachers' perceptions of conceptual organization and selection as well as their perceptions of how to teach general chemistry. This demonstration is carried out through the use of metaphors from new information technologies.

Este texto pretende enfatizar alguns aspectos da vida docente problematizando-os através dos Estudos Culturais e com algumas análises de inspiração foucaultiana. Pretende-se evidenciar os diferentes discursos que formam a identidade docente, bem como a dificuldade enfrentada pelos novos/as professores/ as em sua chegada à escola. Considera-se a escola como possuindo uma cultura específica de produção de saberes e de formação dos docentes que participam de sua estrutura institucional. Os/as professores/as são constituídos/as pelo título e colados/as a ele, onde há uma carga de significados que são deste mundo moderno e que não “podem” ser pensados diferentemente. É claro que esta produção não é exclusiva da cultura escolar, ela se faz intra e extramuros da escola. Essas são as discussões que perpassam todo o texto, enfatizando-se a necessidade de pensar como está sendo narrado, subjetivado e identificado este ser professor/a e quão importante é conhecer estas narrativas. Conhecer é um ato de governo.

This paper intends to emphatize some aspects of teaching life, dealing with troubles based on Cultural Studies and with analysis from Foucault's inspiration. We aim to point out the different speeches that form the teacher's identity, even though the hardness faced by the new teachers in their arrival at the schools. We consider the school possessing a specific culture regarding to the production of knowledge and in the formation of the teachers that participate in its institutional structure. The teachers are constituted by a title and are bind to it. There is a charge of meanings that are proper of this modern world and that cannot be thought in a different way. It becomes clear that this production is not exclusively from a school's culture, it is done in and outside from the walls of the school. These are the discussions focused through the entire text, pointing out the necessity of thinking how this teacher it is being narrated, subjectived and identified and how it is important to know such narratives. Knowing is an act of governing.

This work evidences a survey conducted during a teacher professional qualification in Rio Grande do Sul, Brazil. This survey analysed the textbooks used by these teachers. The dynamics consisted of choosing the analytic criteria used by teachers, and adding new criteria for examining their difficulties and ways to choose textbooks. This article emphasises the problematics and difficulties teachers have to make choices and their loss of skills and authority to consider these books more profoundly.

In this paper we discuss an approach for two initial topics in Chemistry: atomic structure and periodic table. The focus of this approach is the use of educational software resources in the perspective of teacher's formation.
