Reflexões para a implementação do movimento CTS no contexto educacional brasileiro

In the present article we initially situate the historical appearance of the Science-Technology-Society movement (STS). As it is a movement emerging in contexts which are quite different from ours, we then discuss aspects to be considered in the configuration of STS's aims for the Brazilian educational context, identifying potential limitations and challenges. We also remark our...

A biologia nos museus de ciências: a questão dos textos em bioexposições

This paper discusses the process of elaborating texts to be used in science museums.

This research's main goal was to identify the processes and results during the realization of the activities connected...

La célula vista por el alumnado

Using the Mental Models Theory of Johnson-Laird as the theoretical reference, representational drawings produced by pre-university course students are analyzed, aiming to establish deductions and inferences about the possible mental models generated as internal representations. In this analysis, the ways in which students see the Cell are studied and compared with what is shown...

Abstract: This paper presents the main features respect the : *explicitation de theoretical frameworks *selection and organization of scientific contents *integration of cognitive,methodological and affective components of contents The importancie of these processes in science teachers education is detache

Do fazer ao compreender ciências: reflexões sobre o aprendizado de alunos de iniciação científica em química

The paper is based on a study of the laboratory work of undergraduate chemistry students during the time they were involved in undergraduate research projects. The aim of the study was to gain insight into what students learn about the nature of science from this approach to science instruction. The data were gathered through students' and professors' interviews and were analyzed...

Estudos de caso como estratégia de ensino na formação de professores de física

The work is part of a research project that investigates strategies for the formation of science teachers supported by a virtual learning environment. This paper describes a curricular proposal adopted in a physics teacher preparation course, based on knowledge as a construction and on the teacher's spontaneous thought transformation. Cases had been adopted as strategy for the...

Educação anti-racista: reflexões e contribuições possíveis do ensino de ciências e de alguns pensadores

Many writers have reflected on the subject of racism. Nevertheless, this theme has not been discussed by science educators. Taking this into account, the aim of the present paper is to introduce some important concepts involved with racism and discuss how it has developed. The paper also presents some possible contributions from science teaching and from sociology and phsycology...

"Conhecimento tradicional

This article is positioned in the field of cultural studies that includes the school curriculum as a place of disputed legitimacy for the expression of the knowledge of different cultures. Based on this theory, and committed to the empowerment of indigenous Kaiowá/Guarani people, this work aims to understand the specific knowledge of traditional societies and raise issues that...

Resolución de problemas científicos desde la historia de la ciencia: retos y desafíos para promover competencias cognitivo lingüísticas en la química escolar

The objective of this article is to approach the resolution of problems in the construction of knowledge in school science. In first place, show some aspects from specialized Literature. Later, we describe a historical episode of the discussion of Lavoisier and Priestley in S.XVIII about the combustion of the air. This is to be used as a strategy that promotes linguistic...

A intermediação da noção de probabilidade na construção de conceitos relacionados à cinética química

In this work we analyze the way that high school students appropriate the concepts and models related to Chemical Kinetics, mainly the kinetic model of collision between particles in chemical reactions (Collision Theory Model). This investigation was based on the studies of Piaget and Inhelder, of Piaget, Jun and Fischbein, who have analyzed if young students exhibit some kind of...

Aprendizaje escolar y obstáculos: estudio de caso de una profesora de ciencias de secundaria

This article describes a case study of a secondary education science teacher as a part of an investigation-action group. We analyze how reflection and action interact, and the influence on teacher professional development. To undertake this study we have developed a progression hypothesis that we call The Complexity Hypothesis, which progresses from technical efficiency, passing...

Uma hipótese curricular para a formação continuada de professores de Ciências e de Matemática

This paper describes the development and the analysis of a curricular proposal for basic educational level Science and Mathematics teachers' didactic-methodological conceptions evolution. This curricular proposal was carried out in the context of Pelotas Federal University' School of Education. Objectives, curricular structure, and teaching methodologies were guided by the DIE...

A comunicação como barreira à inclusão de alunos com deficiência visual em aulas de mecânica

This paper is a part of a broader study aiming to understand the main barriers for including visual handicapped pupils in physics' teaching contexts. It analyzes communication difficulties between future physics teachers and visual handicapped pupils during Mechanics classes.
