This study presents the results of a study on the development of the concept of force and their possible applications in physics teaching. The historical study has focused on Aristotelian natural philosophy, medieval theories of strength in impressed and on classical Newtonian mechanics. The Newtonian concept of force was also an object lesson of physics analyzed in this study. In this lesson, conducted in a preuniversity course, spontaneous conceptions or alternative conceptions of students about the concept of force proved very entrenched, resulting in studies on the Model Change on Conceptual and epistemological obstacles in view Bachelardian. The theoretical frameworks adopted led us to trace parallels between spontaneous conceptions revealed by the students and some views about the concept of force found in the study of history. The results show that while some old conceptions have been replaced by scientifically Newtonian concept of force, they are still present in the students' ideas and resist to changes even after the study of Newton's laws. Like main result shows that the history of science can be a great ally for the deconstruction of alternative conceptions, particularly when these concepts were previously presented and overcome the course of history of the development of a concept

There are three distinct and complementary objectives The first objective is to present a short historical overview on the establishment of evening courses in Brazil (classes are held on weekdays, generally from 7:00 pm to 10:30 pm), including those in the higher education level, occurred on the middle of last century. The second objective is to demonstrate the growth of evening higher education, considering that in 1998, of the 2.1 million college enrollments, 55.3% were enrolled in evening courses; in 2010, twelve years later, of the 5.4 million students enrolled, there were 63.5% enrolled in evening courses. The third objective is to discuss current public policies to expand evening openings in public institutions which represent nowadays only 16.1% of the 3.4 million enrollments for evening classes. In the third objective it is included the discussion of programs for scholarships and tuition loans. The research results pointed to the importance of federal programs for scholarships and tuition loans for students from private institutions such as the 1,382,484 scholarships since 2004 (PROUNI Program) and the 847,000 tuition loans since 1999 (FIES Program). Important steps have been made by the Brazilian government. Considering that there are 3,987,424 enrollments in private institutions, the effectiveness of the programs for scholarships and tuition loans is still insufficient to meet the universal benefits for the student’s needs. Evening courses became the real instrument of social inclusion for many Brazilian youths and must be expanded quantitatively and qualitatively, with aggressive public policies, including also, scholarships and tuition loans.

The execution of a appropriate odontological surgical treatment for patients with Myocardial Infarction has been based in established protocols for important works in world wide literature during the sixty’s and seventy’s decade, established with a minimum of six months before the noncardiac surgery. The recent advancements in the medical assessment of surgical risk based on the individual analysis of each case with availability of new therapeutic tools in reference to medical or dental treatment, allowing for new procedures that can be used in the execution of safer odontological surgery for each patients. This review of the literature shows the actual tendencies of the treatment of patients with Myocardial Infarction concerning specific care before, during and after surgery based on laboratory evaluation and drug therapy as well as the possibility of surgical treatment before six months post-infarction.

We report here some outcomes of a research related to a didactical experience aiming to integrate the History of Science to the Physics Teaching, taking as background the historical development of the gravitational attraction. The research, of qualitative approach, is a case study and it was carried out in a sample of eleven students belonging to an undergraduate physics program (called licenciatura in Brazil) designed to from High School physics teachers in a São Paulo State Public University. We tried initially to reveal prospective teachers’ conceptions in order to provide a prepare that was used to guide the activities from the reality’s diagnosis. The aim was to promote discussions on the existence and persistence of alternative conceptions, on the historical evolution of the subject gravitational attraction, through readings and debates of texts contemplating recent subjects on the Science Education research, in order to generate dissatisfaction with traditional teaching models. The future High School physics teachers were asked to construct their own teaching proposal, through the development, in real situations, in a High School, of a minicourse based on: debates and synthesis developed in University classroom, the History of the Science and the student’s alternative conceptions. In this paper we will analyze future teachers’ alternative conceptions, the development of the course proposed, and details of the mini-courses taught by the prospective teachers in real situations, among High School students, its coherence and the posture changes observed in them.

This paper intends to reflect on the search, in the process of teaching formation, of pre-defined contents for the teaching of Geography and History in the series of primary school. This desire for clarity about the appropriated contents for the various series often overshadows the real need to clarify what is the goal of teaching this or that content. It is necessary, in the teacher training, resume and historically contextualize this search for curriculum contents. The risk of prioritizing the discussion about contents is transforming the contents itself into the content goals of education. Reifying the contents contributes to the common process of disconnect teaching from learning. In this case, the educational process becomes a contest of teaching contents, not bothering if these contents were or not learned by the students, which makes education extremely conservative. This phenomenon has it origins in the 1970s, during the curriculum discussions of the various areas of school knowledge. Since then, the concept of didactic transposition has been questioned progressively, in which the curricula were designed as adapted teaching to lower levels of scientific knowledge produced in universities – the place for higher education. The school knowledge, since the 1970s, is considered as autonomous. In other words, knowledge in dialogue with university science, but with typical characteristics of education in school systems. If the curriculum of primary and secondary educations is not the result of the didactic transposition, what content it should be made of? The current paper touches this issue, but subordinates it to most relevant questions about the purposes of learning in inseparable connection with teaching.

Sexual Orientation is present in the curriculum of many schools for elementary and high school. This subject generates controversy in the school community. This a fact that leads many teachers postpone the start of this topic. Fifty students participated in this study, 24 boys and 26 girls with average age of eleven years. The study aimed to investigate conceptions on sex in adolescents using the cartoon. The analyzed results suggest that students understand sex as intercourse only. However, there are a multitude of features mentioned by students. These are issues that require further reflection about issues not always discussed in class: pregnancy and abortion, condom use, sexual desire, anal sex, becoming a single mom, group sex, AIDS, prostitution, size of genitals, masturbation, among others.

OBJETIVO: Estimar a prevalência do uso de serviços odontológicos por pré- escolares e fatores associados. MÉTODOS: Estudo transversal com 1.129 crianças de cinco anos de idade da Coorte de Nascimentos de Pelotas 2004, RS, de setembro de 2009 a janeiro de 2010. Registrou-se o uso de serviço odontológico pelo menos uma vez na vida e o motivo para a primeira consulta odontológica da criança. As categorias do desfecho foram: ter feito a primeira consulta por rotina, para resolver um problema ou nunca ter ido ao dentista. Os exames bucais e as entrevistas foram realizados nos domicílios. Aspectos socioeconômicos e variáveis independentes ligadas à mãe e à criança foram analisados por meio de regressão logística multinomial. RESULTADOS: A prevalência de uso por qualquer motivo foi 37,0%. Os principais preditores para consulta de rotina foram nível econômico mais elevado, mãe com maior escolaridade e ter recebido orientação sobre prevenção. Principais preditores para consulta por problema foram ter sentido dor nos últimos seis meses, mãe com maior escolaridade e ter recebido orientação sobre prevenção. Cerca de 45,0% das mães receberam orientação de como prevenir cárie, principalmente fornecida por dentistas. Filhos de mães com história de maior aderência a programas de saúde tiveram maior probabilidade de ter feito uma consulta odontológica de rotina. CONCLUSÕES: A taxa de utilização dos serviços odontológicos por pré- escolares foi inferior às de consultas médicas (puericultura). Além da renda e da escolaridade, comportamentos maternos têm papel importante no uso por rotina. Relato de dor nos últimos seis meses e número elevado de dentes afetados por cárie, independentemente dos demais fatores, estiveram associados ao uso para resolver problema. É necessária a integração de ações de saúde bucal nos programas materno-infantis.

This article aims to analyze the movement of weavers' strike (according to an specific context), its origins, actions and consequences, prompting the internal system of factories (their regulations), the hierarchical relationships of power, and struggles to guarantee the right of association, which resulted in the stoppage of all activities of the textile sector. The attitude to go on a strike, mobilizations and the stroll show that the direction of the movement and the working class were aware of their actions and those likely consequences, what signalize, beforehand, the ideological, classist and political character of women´s actions: radicalized by the practices of confronting the authoritarianism employers and threats (police repression, harassment of the press). They endured through the collective support and a network of solidarity
