Early this century, several crises are intertwined and the environmental crisis is the most global of them all. In this context, emerged as an environmental education learn to overcome the crisis. This article aims to discuss the ideas of biology teachers in the city of Piracicaba-SP on Environmental Education and from there to reflect on the theme of inclusion in the initial training of teachers. The methodology used a structured questionnaire-based instrument VOSTS (Views on Science-Technology-Society), produced by Aikenhead and Ryan (1992) and the data were analyzed qualitatively. The results indicate that the biology teachers surveyed still have a naive conception of environmental education and training courses need to commit to structural and curricular changes that make the effective insertion of the subject in teacher training in the region studied.

Neste trabalho, relatamos as propostas que temos efetivado em três disciplinas que abordam conteúdos de Ciências e de Meio Ambiente, em um curso de Pedagogia. Nessas disciplinas, procuramos propiciar o desenvolvimento de práticas investigativas, que articulem conhecimentos de diferentes campos, contribuindo para uma visão integradora da realidade e para a exploração das múltiplas relações entre Ciência, Tecnologia, Sociedade e Ambiente (CTSA). Entendemos que a realização de trabalhos com esse enfoque, durante a formação, pode contribuir para a valorização das áreas de Ciências e Educação Ambiental e de seu ensino por parte dos docentes em formação e, como consequência, para o enriquecimento da prática educativa com crianças nos anos iniciais da escolarização.

A culture of resistance in the semi-arid, expressed by mentalities and values, goes against the economic potential of sheep and goat raising, considered as an inferior activity when compared to the cattle raising, historically linked to social status and prestige. This paper attempts to shed light on aspects that make possible to clarify the roots of the cognitive apparatus that supports this view, resorting to it to the production of relevant authors dealing with the issue of displacement of colonizer and livestock in the hinterlands. Ultimately, it seeks evidence of the influence of the historical process of economic and social organization of space on the present.

As an alternative to improve the adaptation of prefabricated posts in flared canals and weakened roots, the option is for relining prefabricated pin, known as a technique of anatomical post. This technique, which can be made with composite resin increases the adjustment post to the walls of the canal and reduces the cementing line, causing the retaining post is less dependent on the mechanical properties of the cementing agent. This article aims to provide an overview of anatomical posts, specifically in the last two decades, based on studies extracted from Scielo, Scopus and Pubmed, referring to the following terms of MeSH Data Base: custom made fiber post, indirect fiber glass posts, root canal therapy and post and core tecnique. According to the literature review in this article, it can be concluded that this technique has been used by several authors and has been shown effective and promising, it creates an individualized retainer with better adaptation and decreased mechanical imbrication cementing line .
