Clinical decisions in dentistry are often based on the knowledge obtained during graduation, clinical experience, information shared with colleagues and professor, textbooks, seminars, conferences and continuing education courses. However, it is necessary to know if this information is derived from scientifically validated researches since too much information may complicate this process. Initially in medicine and later in other health areas a method which enables a critical evaluation of scientific papers related to a specific issue and also, whenever it is possible, an evaluation of the results by meta-analysis,was developed by Cochrane in order to reduce the bias towards all information obtained. The aim of this work is to present some aspects of the Evidence Based Dentistry (EBD) and to show how this methodology can be used to better substantiate scientifically the clinical decision of the dentist and improve researches design with scientific validity. The paper discusses editorial trends focused on the EBD, shows the differences between a systematic and a conventional review, describes data about Cochrane and the advantages of scientific evidence synthesis and the implications of EBD for clinical practice and research as well as recommendation grades and evidence levels of general scientific studies.

The teaching of Science is one great challenge not only for educators but also for researchers in our country. In a globalized world where the social foundations, cultural and economic depend fundamentally on science and technology, science education is a basic requirement for the exercise of citizenship. Multiple initiatives have been taken to improve the quality of teaching of science practiced in our schools: the ReAction Program is the result of a set of actions developed by a public educational policy that invests in improving the Teaching of Science the elementary school. In this work, we present a history of this program and the search on the contribution and the actions developed, the collaborative research with a group of teachers-multiplier, and the evaluation of the teaching of science, measured from notes, frequency and speech teacher.

In Brazil, the discussion about thereplacement of analog television signals to digitaland its impact on society, in media companies andgovernment began in the 90s. Embryonic steps towardsdigitalisation of the television signal ground were thegovernment of Fernando Collor de Mello (1990-1992),with advances during the government of FernandoHenrique Cardoso (1994-2001) and in the governmentof Luiz Inacio Lula da Silva (2002). The academy startsthe discussion in 1996. This article aims to bring to lightthe results obtained from the survey Digital television:a historical perspective , which received the supportof CNPq for funding of two scholarships for scientifi cinitiation between August 2008 and July 2009. Theproject sought to identify what has been published onthe subject in the fi eld of Social Sciences and from threemacrodescritores (information management, publicpolicy and value chain), providing the li ing of a virtualcollection Zotero bibliographic innovative platform.The mapping serves to show the growing interest anddevelopment of research in the country during theperiod - when the number jumped to three works inthe fi rst seven years (1995-2001) to 198 in the last sevenyears (2002-2008). The research sought to identify themajor authors and works related to digital televisionand published in the country. The survey took intoaccount books, articles published in books, journals,Annals of Compós and Intercom, and dissertations andtheses. Data and refl ections on the survey are containedin this communication.

This survey attempted to find out whether or not the management styles adopted by schools can be associated with teacher stress. The study considered 175 teachers working with 1st‑to 4th grades in twelve public schools. The instruments first identified the leadership style predominant in the schools, then sought to identify the presence of stress in the teachers. Although stress was present in the majority of the teachers, an association with specific management styles could not be confirmed. This can be linked to the fact that the stress was already present in the teachers and did not allow the identification of additional influence by the schools’ leadership style

The use of technologies called computedassisted, such as CAD - (Computed Aided Design), CAM - (Computed Aided Manufacturing) and CNC - (Computed Numerical Control), increasingly demanded by the market, are needed in the teaching of subjects technical drawing and design courses for engineering and design. However its use findl barriers in the more conservative wing of the academy, who advocate the use of traditional drawing, for the settling of the concepts and the development of spatial reasoning. This study aimed to show the results obtained with the design and production of an apparatus for measuring a three-dimensional computer-aided milling machine, interaction, integration and consolidation of concepts, fully demonstrating that the learning of computer-assisted technology is possible, and its use is most appropriate, meaningful and productive, than the use of instruments in the classic design.

In the Brazilian public archives,it is not unusual to find photographs recording the daily school educational institutions since at least the early twentieth century. The historian often has conceptual difficulties in dealing with the photographic documentation as a research source. The current workproposes to present the debate over the use of photographyas a privileged source for research on Education History. Photography can be an instrument of knowledge and information for observers awayfrom the place and time in which the images originated. Its contents have been tentativelyused in researchfor the Historyof Education. The methodologyof this studywill approach the ideas proposed byBoris Kossoyand Susan Sontag on photographyas a record of realityand its use in historical research. As interlocutors with the ideas of these three authors will be presented photographs of reports from the Regional O ffice of Education in the 1930s,preserved in the Public Archives of São Paulo. It is the purpose of this study to help researchers in History of Education in methodological reflection on the use of photographs as documentarysource of research.
