Purpose of this monograph is a critical review of articles and publications worldwide. The insertion of green chemistry concepts in the curriculum components of general chemistry lab, plays a fundamental role in the early years of a Chemistry course towards early embed the philosophy of green chemistry. The fundamental concepts of green chemistry are highlighted in order to present the huge number of challenges in developing new chemistry l in research, industry and education. The practice of a chemical that takes into account ethical environmental attitudes thought since the formation of professionals, may lead to adoption of technical microscale, replacement of toxic agents, reduction of waste generation, etc. who snore a lot with the concept of sustainability

Este artigo descreve um conjunto de atividades educativas desenvolvidas no âmbito do projeto “Lab InCognITA – Laboratório de Inovação em Cognição, Informação, Tecnologia e Aprendizagem”, que objetiva promover o desenvolvimento de um conjunto de atividades e projetos com escolas públicas de nível médio, vinculadas à Diretoria de Ensino de Guaratinguetá, buscando despertar o interesse dos alunos para as áreas tecnológicas e engenharias. Destaca-se a importância dos recursos didáticos, em especial os baseados em experimentação, para promover uma melhoria no interesse dos estudantes pelas ciências exatas. A operacionalização do projeto é descrita por meio da apresentação das atividades previstas para o seu desenvolvimento, e de como estas são realizadas durante eventos denominados “Visita à UNESP”, em que alunos das escolas vêm até o Campus da UNESP – Guaratinguetá. Os resultados parciais obtidos sugerem que as atividades desenvolvidas durante as visitas têm contribuído para despertar o interesse dos estudantes para as áreas de Exatas e Engenharias.

We report here a study about the application of a formal teaching strategy about heat and temperature concepts applied among high school students. The strategy belongs to a research trend which deals with epistemological analogies and has an innovative character related to the students’ preparation for rational debates between conceptions and/or rival theories, using didactical rational reconstruction (DRR) which aims to help scientific concepts rational learning. We investigate the outcomes of this preparation and students’ conceptual development, analyzed through a qualitative-interpretative methodological approach.

This article is part of a study that seeks to understand the main barriers to the inclusion of visually   impaired   students   in   learning   Physics.   Analyzing  modern physics classes, we examine the difficulties in communication between teachers and visually impaired students. Our study emphasizes the analyses of empirical­sensory and semantic structures of speech, indicating factors that may hamper  students’ understanding in the classroom. We recommend alternative procedures that aim to facilitate the effective participation of students with visual impairment in the communication process, such as:  elimination of the interdependent   audiovisual structure and the exploration of the communicational potentialities of a speech based on empirical structures whose accessibility does not depend on visual skills.

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.

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.

The aim of this paper is to discuss the problematization in Physics Teaching subsidized by a methodology based on the steps of the process of psychoanalysis proposed by Santos (1998) and based in Bachelard’s epistemology. The work was developed and applied in extracurricular course and it was investigated at conceptions of students of the degree in Physics from Unesp-Bauru about the topics of the electromagnetism. The data were categorized into level of complexity and showed in tables and graphs. The results allowed us to infer the conceptual or epistemological profiles of the sample investigated.

In this paper, we analyze the educational importance of teaching Physics in the early grades of elementary school from a teaching experience with students of 5th grade, using five experiments on electricity and magnetism. The theoretical framework used was the socio-historical psychology, especially Vigotski's studies on concept formation. It can be stated that the teaching of Physics and the use of experimental activities in the early grades cannot be simply associated to the teaching of certain scientific concepts, but should be explored bearing in mind the child's development.

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.

Our work aims to discuss the teaching of science in the context of informal education. Thus, we present and analyze the results of an initiative that we have made seeking to interest high school students to study sciences and technology. The Energy shows are activities which are presented in experimental demonstrations of science concepts to middle school students. After the show the students respond to a questionnaire which formed the basis for this study. The results indicate that the achievement of shows have had an impact on students.

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.
