Institutional entrepreneurship and professionalization of the rural development of the sisal region in Brazil

This work analyses the professionalization of rural development in the Brazilian Northeastern region and how this created opportunities for entrepreneurship when the professional practices of funding bodies were transformed in accordance with local reality. This professionalization has its own characteristics, including fluid formats and the rolling out of networks, and it contributes to the theorization and dissemination of certain practices instead of being concentrated in professional associations and formal links with educational institutions. The main implications are commonly related to institutional processes related to professionalization, such as the emergence of certain organizational formats and the dissemination of professional practices that are considered legitimate. An additional consequence was observed in the area of rural development: the ideas and practices disseminated through professionalization were reinterpreted when the local entrepreneurs adapted them to their own thinking and needs.

Ações de divulgação de química na Casa da Descoberta - centro de divulgação de ciência da Universidade Federal Fluminense

It presents a brief history of CD and discusses the difficulties concerning the dissemination of Chemistry at Scientific Dissemination Centers. This work also approaches some activities developed throughout the years: experiments performed in relation to the visitors' daily life, training of monitors to act as mediators in the non-formal teaching of Chemistry, production of dissemination materials, elaboration of books, as well as activities that relate formal to non-formal education.

Mapa da rede social de apoio às famílias para a promoção do desenvolvimento infantil

Pesquisa descritiva, com abordagem qualitativa, realizada de setembro a novembro de 2009, em uma unidade de saúde com Estratégia Saúde da Família, de um município da região metropolitana de Curitiba-PR, com oito famílias, representadas por mãe, pai e avó. O objetivo foi identificar a rede social de apoio às famílias para a promoção do desenvolvimento infantil, na perspectiva das famílias. A coleta de dados ocorreu por meio da técnica de grupo focal, e os dados foram analisados segundo a análise de conteúdo. A rede social de apoio às famílias foi classificada como localizada, composta por 16 membros distribuídos entre rede informal e formal, estabelecidos por relações íntimas, com menor grau de compromisso e ocasionais. Considera-se que o entendimento por parte dos profissionais de saúde referente ao papel e importância dessa rede favorece a proposta de entrelaçamento entre os membros que contribuem para apoiar famílias na promoção do desenvolvimento infantil.

Quimiluminescência orgânica: alguns experimentos de demonstração para a sala de aula

The generation of "cold light", visible to the human eye, by chemical reactions has attracted the attention of the scientific community since the beginning of this century. Besides the academic interest in the elucidation of the mechanisms of excited state formations, many chemiluminescence reactions have found widespread analytical applications. Moreover, the phenomenon of chemiluminescence can also be used as a tool in undergraduate and college teaching. In this article, we describe several known chemiluminescence demonstrations, which are suitable for school teaching. The main objective of this work is to produce didactic material in Portuguese to stimulate Brazilian secondary and high school teachers to use these experiments in the classroom. The demonstrations include singlet oxygen emission, the luminol reaction, oscillating chemiluminescence and the peroxyoxalate reaction.

Química orgânica experimental: integração de teoria, experimento e análise

A new approach for teaching in basic experimental organic chemistry is presented. Experimental work goes on parallel to theoretical lectures leading to an immediate application of theoretical concepts transmitted therein. One day/week is dedicated exclusively to the organic laboratory. Reactions are proposed as problems to be solved; the student has to deduce the structure of the product on the basis of his observations, the analytical data and his mechanistical knowledge. 70 different experiments, divided in 7 thematical chapters, are presented. All experiments require the analysis and discussion of 1H and 13C NMR, IR and UV spectra. Additional questions about each reaction have to be answered by the student in his written report. Laboratory safety is garanteed by the exclusion or substitution of hazardous and toxic reagents. Microscale preparations are adopted in most cases to lower the cost of materials and the amount of waste. Recycling of many reaction products as starting materials in other experiments reduces the need for commercial reagents and allows the execution of longer reaction sequences. Only unexpensive standard laboratory equipment and simple glassware are required. All experiments include instructions for the save treatment or disposal of chemical waste.

Eixos mobilizadores em química

Over the last five years there have been significant changes in higher education in Brazil as well as in research funding. As a contribution to the development of Science and Technology, and aiming to portray Chemistry today in Brazil, in the context of last year´s elections for President, State Governors, National Congress and Legislative Chamber, the Directors and Consulting Council of the Brazilian Chemical Society, SBQ, initiated in 2002 a series of activities to produce a document entitled Mobilizing Axes in Chemistry. This discusses undergraduate and graduate teaching in Chemistry, a new model for research funding, and the overall state of the art, and future perspectives. Six mobilizing axes have been identified and discussed to date: 1. Training of highly qualified personnel; 2. Decentralization, and discouragement of institutional in-breeding; 3. Stimulation of entrepreneurship and interdisciplinarity; 4. A guaranteed budget for Science and Technology; 5. Proactive interaction of academics with economic activity; and 6. Removal of institutional bottle-necks of all sorts. The Brazilian Chemical Society hopes that the new administration will in the near future begin the task of improving the national education system and increase funding for Science and Technology.

Constituição de professores universitários de disciplinas sobre ensino de Química

This paper focuses on the teaching development practice in the field of chemistry covering such disciplines as chemistry teaching practice, chemistry teaching instrumentation and chemistry teaching methodology and/or didactics, thereby describing and analysing the logics of the development practice and the role of teachers as well as the epistemological identity configurations (knowledges which are proper to said identity) within this discipline field.

O que sabemos sobre os primeiros livros didáticos brasileiros para o ensino de Química

This paper deals with the Brazilian textbooks of Chemistry from the XIX century to 1930. After presenting the science and its teaching contexts in Imperial Brazil and describing the first Chemistry textbook written by a Brazilian, the state of knowledge about these prime Brazilian books is presented. These works show the texts had strengths overlooked by current materials, a fact confirmed by analyzing textbooks from three authors from the period. The study concludes by compiling a list of 50 titles of early Chemistry books to help guide future research.

MOTIVAÇÃO PARA A CARREIRA DOCENTE E CONSTRUÇÃO DE IDENTIDADES: O PAPEL DOS PESQUISADORES EM ENSINO DE QUÍMICA

This research aims to identify the reasons that lead students to pursue a specific course of chemistry teacher training, i.e., their perspectives on the course and the teaching career, and if they are motivated by trainers to become basic education (BE) teachers. It was concluded that most students did not want to be teachers of BE. They identified through the social context of the course that the teachers focused on the area of chemistry teaching sought to motivate them for this career, whereas the teachers of these specific areas of chemistry encouraged them to seek other career opportunities.

BLOGS NO ENSINO DE QUÍMICA: ANÁLISE DE COMENTÁRIOS PUBLICADOS EM DISCIPLINA DE COMUNICAÇÃO CIENTÍFICA

Blogs and other technology tools are commonly used in our society. Although we are familiar with the use of technology for social interaction, its application in the classroom environment is still not fully appreciated by the teaching community as a useful learning tool. This paper sheds light on this use by presenting the analysis of the comments posted on a blog used by undergraduate chemistry students for a scientific communication undergraduate course. On the course, students used the blog to ask questions and discuss assignments. All the comments were monitored by the professor and her teaching assistant, who also posted their comments. We analyzed the content of these comments using the model proposed by Henri and adapted by McKenzie and Murphy. The results show a predominance of administrative comments, followed by course content comments. The findings also indicated that this tool complements classroom discussions, supports the participation of students who would otherwise not take part, and allows a continuous learning process for all the students. We concluded that the use of blogs improved the classroom experience and supported the instructional classroom activities.

CONHECIMENTO PEDAGÓGICO E CONHECIMENTO QUÍMICO NA FORMAÇÃO DE PROFESSORES: A CONSTRUÇÃO DA IDENTIDADE DOCENTE

This paper presents results of a content analysis of the formative professional profile of undergraduates within the context of Brazil's expansion of its federal education system and implementing of teacher training policies. The analysis focuses on the conceptions of undergraduates regarding elements of their initial training and professional perspectives, as recorded in narratives, interviews, and questionnaires. Based on the relationships identified between the recorded content and the Educational Course Project, we identified three categories of analysis that point to tensions generated during the professional development of chemistry teachers: 1) The relationship between pedagogical knowledge and chemical knowledge; 2) the conceptual aspects of science education, as represented by the different ways that students understand the "ionization process"; and 3) teaching identity, including the elements indicative of the identity construction of future teachers. The results indicate that the educational and professional profile of undergraduates is marked by a particular tension between chemical content knowledge and pedagogical content, as well as a lack of objectivity and focus on the course's original intent. This situation has produced a multifaceted training context in which there is confusion regarding aspects relating to the licensing, teaching modalities, and preparation of the chemistry education professional.

System to outline the graduatestudents

Objective: to evaluate the system to outline the graduate students from the Post-Graduate Programs of CAPES Medicine III area. Method: it was analyzed the book of indicators and the Document of Area of the Post-Graduate Programs of Surgery, also checking the literature about this issue. Results: there was a paucity of data from most of the programs, as regards to the methods for evaluation of graduate students. The current system lacks a standard and an institutional support to outline the graduate students. In the public system there is a concentration of postgraduate students in Medicine; however, they represent a small part of those Brazilians students who finished their graduation courses in Medicine. In the current context, the quest for the post graduate courses and consequently for a research field or even a teaching career, has been replaced by the private sector jobs and the labor market, both in non-academic assistance activities. Conclusion: it is imperative to establish not only science and technology innovation policies but also educational and health policies acting harmoniously and stimulating the qualification and the teaching career, improving the post-graduate courses. It is necessary to develop a single form under the institutional guidance of CAPES with the conception of a National Program for Graduate Student in order to consolidate guidelines to mapping the graduate students of post-graduate programs in surgery, in our country.
