Marcos da história da radioatividade e tendências atuais

The first days of radioactivity, the discoveries of X-rays, radioactivity, of alpha- and beta- particles and gamma- radiation, of new radioactive elements, of artificial radioactivity, the neutron and positron and nuclear fission are reviewed as well as several adverse historical marks, such as the Manhattan project and some nuclear and radiological accidents. Nuclear energy generation in Brazil and the world, as an alternative to minimize environmental problems, is discussed, as are the medicinal, industrial and food applications of ionizing radiation. The text leads the reader to reflect on the subject and to consider its various aspects with scientific and technological maturity.

Compreensão da sexualidade por jovens com diagnóstico de deficiência intelectual

The study describes the comprehension of concepts about sexuality by youths diagnosed with intellectual deficiency, during classes on sexual education. The analysis of selected episodes from video transcriptions of five classes (Human Body, Kiss, Flirting, Coitus, Condom/STD) showed: the appropriation and understanding of concepts, partial difficulties of comprehension, and inhibition. The analysis of the transcripts indicated that all students were attentive to the classes, participated in the proposed tasks, and answered the questions. The observed signs of inhibition and the expression of values were similar to those observed in other youngsters, indicating the appropriation of culturally established values. The obtained evidences contrast with mythical visions related to sexuality in these youngsters, and suggest more studies about their competences.

História, filosofia e sociologia da educação matemática na formação do professor: um programa de pesquisa

We present and discuss in this article some features of a research program whose central object of investigation is the way in which the recent fields of history, philosophy, and sociology of mathematical education could take part in a critical and qualified manner in the initial and continuing training of teachers in this area. For that, we endorse the viewpoint that the courses for mathematics teacher education should be based on a conception of specificity through which a new pedagogical project could be established. In such project those new fields of investigation would participate, in an organic and clarifying way, in the constitution of multidimensional problematizations of school practices, in which mathematics would be involved, and that would be guided by academic investigations about the issues that currently challenge teachers in the critical work of incorporation, resignification, production, and transmission of mathematical culture in the context of the school institution.
