A competência reflexiva processual em serviço social na ação profissional junto às populações

Este artigo resulta de pesquisa etnográfica desenvolvida em Portugal, Brasil e Canadá sobre a atividade profissional dos assistentes sociais e se centra nos aspectos relacionados ao saber que se mobiliza na interação junto às populações. A atividade profissional dos assistentes sociais responde a problemas vividos por indivíduos de forma singular, mas que decorrem do funcionamento das estruturas socioeconômicas e políticas e de seus sistemas que influenciam percursos, modos e condições de vida de pessoas, grupos e identidades individuais e coletivas. A resposta a esses problemas da ação exige um saber profissional proveniente de uma estrutura sociocognitiva específica que está na base da forma identitária que se constrói e reconstrói pela reflexão individual e coletiva e pela afirmação da autonomia profissional na ação. Os profissionais trabalham em tensão permanente, intrínseca à própria ação, para reinventar e adaptar procedimentos difíceis de codificar e formalizar no cruzamento de relações sociais complexas com lógicas individuais e coletivas diversas e mesmo antagônicas. Tensões, conflitos e limites nos contextos de interação com as populações são fatores de complexificação e de incerteza no saber. Mas, para agir nessas condições, o profissional precisa de algum padrão de regularidade e de generalidade que se constituem como procedimentos profissionais de seu saber de ação, como mostra este artigo.

Correio eletrônico como recurso didático no ensino superior: o caso da Universidade Federal do Ceará

O correio eletrônico é uma aplicação popular da Internet, constituindo-se um incentivo para os professores integrarem esse recurso tecnológico em suas disciplinas, podendo ser utilizado como uma técnica para aprimoramento do ensino-aprendizagem. Algumas disciplinas de cursos de graduação e de mestrado da Universidade Federal do Ceará vêm contemplando os alunos matriculados com a utilização do correio eletrônico, com o propósito de melhorar o intercâmbio das informações entre os alunos e entre estes e os professores. Esta pesquisa teve como objetivo fundamental avaliar a opinião dos alunos sobre o uso do correio eletrônico e o sucesso instrucional proporcionado pela sua utilização. Aplicou-se um instrumento, contendo duas escalas de opinião, em uma amostra aleatória de 123 alunos de disciplinas que usam o correio eletrônico. Observou-se que somente 27,6% dos entrevistados apresentaram alto nível de concordância nos 13 itens da escala referentes à utilização do correio eletrônico como recurso. No entanto, 72,5% dos respondentes à escala com 12 itens sobre o sucesso instrucional e a troca de experiências apresentaram alto nível de concordância.

Promovendo a argumentação no ensino superior de química

Studies have demonstrated the importance of argumentation in science education. Based on this assertion, we have tried to develop argumentative abilities in chemistry undergraduate students through a teaching methodology based on case studies. The process culminated with class presentations by student groups about possible solutions for the cases. To assess the quality of students' argumentation, videotapes of group presentations were collected and analyzed using Toulmin's Argument Pattern (TAP). TAP illustrates the nature of an argument in terms of claims, data, warrants, backings, and rebuttals. The findings of this work support the idea that the case study approach is an effective strategy for enhancing students' ability to argument.

Gestão integrada de resíduos químicos em instituições de ensino superior

Since chemical residues management must be seriously considered at institutions of higher education and due to the relevance of this subject for students, this work proposes the involvement of the scientific community in the establishment of a program for management of chemical residues at universities, starting with a committee, to coordinate the process. The program should integrate the entire scientific community in an organized effort. The program involves legislative, educational and environmental management aspects, with environmental education as an important tool to integrate all the administrative areas of a chemistry department.

Artigos científicos como recurso didático no ensino superior de Química

Chemistry teachers increasingly use research articles in their undergraduate courses. This trend arises from current pedagogical emphasis on active learning and scientific process. In this paper, we describe some educational experiences on the use of research articles in chemistry higher education. Additionally, we present our own conclusions on the use of such methodology applied to a scientific communication course offered to undergraduate chemistry students at the University of São Paulo, Brazil.

Implantação das diretrizes curriculares nacionais para formação de professores de química em uma instituição federal de ensino superior: desafios e perspectivas

The Curricular Proposals for Chemistry Teaching Courses aim at producing a reflexive-researcher teacher, who will be able to deal with cross-disciplinary subjects. The challenge faced by the majority of the federal universities, in implementing these guidelines, is to attain these objectives inside their departmental structure. We present here the formulation of the Chemistry Teaching Course Pedagogic Project from Federal University of Pelotas concerning on the CNE/CP 1/2002 and 2/2002 Resolutions. We discuss the impact of these Proposals, the difficulties faced and the new perspectives of organization inside of these institutions, which resulted in new spaces with cross-disciplinary and cross-departmental orientation.

Formação docente no ensino superior de Química: contribuições dos programas de aperfeiçoamento de ensino

The literature on the challenges of teacher education in undergraduate chemistry teaching is limited. In the present study, the application of didactic proposals elaborated by two authors of this paper, graduate students and teaching assistants of the teaching improvement program at University of São Paulo, was investigated in terms of their contribution to the teaching assistants' education and undergraduate students' receptivity toward them. Such proposals were based on the jigsaw cooperative learning strategy and applied in two undergraduate courses. The results indicate students' good receptivity and suggest their importance to teaching assistants' education.

Jogos de empresa: aplicação à gestão da qualidade no ensino superior de química

Business games have become a popular choice of pedagogical technique for teaching in higher education. The objective of a business game is to offer students the opportunity to learn by doing, engaging them in a simulated experience of the real-world. This paper discusses how a business game has been played by undergraduate chemistry students in a Quality Management course. The responses from the teaching evaluation questionnaires revealed that they not only improved their quality management practices, but also enjoyed working in teams. The level of participation by students was good and the classroom activities provided a meaningful learning experience.

O conceito de eletronegatividade na educação básica e no ensino superior

The goal of this study was to examine the means used by textbook authors to introduce, define, and explain the electronegativity concept in high school and introductory college chemistry textbooks. Results obtained showed that most textbooks lacked history precedence and did not deal with the conceptual understanding and manifesting a strong standardization of characteristics that, from our point of view, do not favor the teaching-learning of the electronegativity concept.

Investigando a presença da história da ciência em livros didáticos de Química Geral para o ensino superior

This paper aims at analyzing the history of science content of three general chemistry textbooks used in Brazilian universities: the translations of Kotz and Treichel's Chemistry & Chemical Reactivity, Atkins and Jones's Chemical Principles, and Garritz and Chamizo's Química. Results revealed different trends for the inclusion of history of science in chemistry teaching. Kotz & Treichel and Atkins & Jones used history mainly as curiosity and ornament. Garritz & Chamizo adopted the historical approach as one of the organizing axis of their textbook. Nevertheless, the historical content of the three textbooks may be criticized from current historiographical standpoint.
