Em Portugal, a partir de finais da década de 1980, têm-se acentuado as dificuldades de inserção profissional dos diplomados do ensino superior nas diferentes áreas científicas e, ao nível da empregabilidade, o desemprego entre os licenciados passa a consubstanciar-se como um problema social, no quadro de um fenómeno estrutural assente na relativa massificação deste grau de ensino que origina uma alteração radical da relação entre a escola e o mercado de trabalho, inviabilizando a possibilidade de estabelecimento de formas de planeamento e de regulação entre o sistema de ensino e o sistema de emprego, entre a qualificação e as necessidades de mão-de-obra qualificada. Este problema passa a reflectir-se no campo das tecnologias da saúde a partir da última década, em que se verificaram alterações profundas nos cenários de empregabilidade com a alteração da relação entre a oferta formativa e a oferta de trabalho/emprego, devido sobretudo ao exponencial aumento da oferta de ensino nesta área que é muito superior aos lugares disponíveis no mercado de trabalho. Até ao início da década de 2000, o desemprego não constituía um problema nas diferentes áreas funcionais das Tecnologias da Saúde, pelo contrário, em geral, existia uma oferta de trabalho superior à procura, o mercado absorvia os diplomados e criou a possibilidade de acumulação do exercício profissional para grande parte destes profissionais. Actualmente, não há dados seguros sobre a real dimensão do problema, contudo existe uma tendência crescente para este se acentuar, com efeito, entre 2000 e 2009, o número de escolas que ministram cursos nas áreas das Tecnologias da Saúde multiplicou-se (6 em 2000 e 24 em 2009), estando no conjunto dessas escolas matriculados 14318 estudantes (ano lectivo 2008/09 - Fonte: Gabinete de Planeamento, Estratégia, Avaliação e Relações Internacionais â GPEARI do Ministério da Ciência, Tecnologia e Ensino Superior), ou seja, cerca de metade das cédulas profissionais que eram 27361 em 2010 (Fonte: Administração Central do Sistema de Saúde - ACSS), mesmo considerando que esse número possa não representar o total de profissionais destas áreas. Este cenário impõe um estudo rigoroso sobre a incidência do desemprego e das diferentes formas de inserção profissional dos diplomados nos cursos do campo das tecnologias da saúde como base para se definirem estratégias activas de promoção de emprego e inserção profissional, de modo a minimizar o problema. Embora a transição do ensino superior para a actividade profissional se enquadre num processo multidimensional que envolve dinâmicas sociais, económicas e políticas que ultrapassam a esfera de acção das instituições escolares e, portanto, a inserção dos diplomados não dependa apenas das instituições de ensino, estas têm a obrigação de se preocuparem com o destino profissional daqueles que aí foram formados. Consciente deste aspecto, a Escola Superior de Tecnologia da Saúde de Lisboa (ESTeSL) tem identificado esta necessidade em diferentes «Planos de Desenvolvimento», desde 2002. à neste contexto que se apresenta este relatório com o intuito de expor os resultados do estudo efectuado acerca das diferentes formas de inserção profissional dos diplomados da ESTeSL nos últimos anos e criar as condições para implementar um Observatório Permanente de Análise e Acompanhamento da situação (inserção profissional dos ex-estudantes da ESTeSL), ferramenta importante para a definição de estratégias futuras, delineadas com base no conhecimento e reflexão actualizada sobre o tema.

This work presents the use of projects as an alternative for teaching statistics, for that it was elaborated a Project that involves the educational socioeconomic reality from the families of the students and built a link between the reality and the scholastic knowledge. This project was applied in Sesi School - Pato Branco between the months of August to September 2014 with 25 students from the 1o and 2o grades from High School. To work the statistics concepts a questionnaire was applied for the parents of the students of the Project´s, they answer it and through these answers the students made frequency tables and graphs, besides measure calculations on measures of central tendency and dispersion measure. All of the construction were realized manually and in the Excel spreadsheet and some of them were chosen to be in this work to with the purpose of showing the hits and the mistakes done. The students worked in groups of 5 students, except in the last class when it was done a test referring to the contents taught in the classroom and a questionnaire for them to evaluate the project´s application. The results show that the teaching of Statistics trough projects motivate the students interest, stimulating the statistical reasoning, in addition made the students know a Math that was different from the one they have already known, with a lot of calculation but with no final objective.

This paper presents a differential approach of financial mathematics developed in high school, focusing on financial education. We seek through the insertion of texts, analysis of some financial products and by the interpretation of problems to contribute to the financial training of students. Aiming to make financial mathematics more attractive and accessible to the day-today, there are available for studies some practical tools like the citizen calculator which are available for computers and mobile phones. As well as spreadsheets and software Geogebra, that allow you to compare and analyze the financial costs of consortia, financing and financial applications,in addition to being allied in the preparation and control of personal and family budget. By applying the teaching sequence proposed in a nocturnal class of high school, we realized some difficulties that have limited the financial learning of math concepts.Yet identified progress regarding the financial education of students. These observations were made through qualitative and quantitative analysis from notes in the field diary and also answers given by students in specific form.

This study will introduce a brief history of the Geometry development, focused in the appearing of the organization in the logical deductive structure achieved by Euclid. Following will be discussed the situation of the learning and teaching of geometry topics since antiquity until the present day, where we will notice that it does not happen with the logical-deductive perspective. After this contextualization, we will propose the realization of a geometry workshop for students of the sixth grade of elementary school, focusing to the development of logical-deductive reasoning. Applied to workshop, changes were observed in the organization of thought of the participating students in the research, furthering the understanding of the concepts and properties of flat euclidean geometry.

This essay presents a proposal on methodology over the mathematical object Exponential Function which enables the development of interpretative and creative skills with potential meaning to the students starting from a didactic sequence structured on the light of The Theory of Didactic Situations from Guy Brousseau and, from the Records of Semiotic Representation of Duval, providing interactions among the students, the teacher and the environment of cooperative learning where the students feel free to express their own ideas as well as to suggest their own approaches. The methodology presented has been developed according to the students first knowledge, valuing their different ways of registering, which have such an important role during the teaching and learning processes. The proposal has been applied to the students from the first year of high school of Colégio Estadual José de Anchieta Ensino Fundamental e Médio, located in a town called Dois Vizinhos âParaná. In order to the development of the research the methodological tool Didactic Engineering Artigue which consists in a methodology developed only to the research with didactic situations. The main goal has been reached at first, which was to work on the conceptual part of the Exponential Function, the relation of dependence and its main characteristic so that the variable part is in the exponent. Moreover with no imposition but starting from suitable didactic situations, the students were able to realize that they could solve the problems which involve the exponential function and furthermore create new problems (according to their universe) modeled by this kind of function. Its believed that the methodology based on the theory of didactic situations, analysis of students registers, observation on mistakes and obstacles as well as reflections over the aspects of the didactic contract are of fundamental importance to the teaching practice and determinant during the teaching-learning process.

This work presents results, reflections, conclusions and considerations about the research entitled "Social representations of environmental education and objectivations in teaching practices in elementary school ". She intended to make known research whose objectives were to know the current environmental education framework (EA) developed by the teachers of the early years of elementary school of that city; identify their social representations about EA and the ways in which these representations are objectified in their teaching practices. Thus, the methodology is characterized by the qualitative approach; whose data collection instruments were the Free Evocation Questionnaire (QEV), the semi-structured interviews and documentary research. The QEV consists of free recall questions and essay questions, whose data is quantitative and qualitative. Data from this instrument were analyzed according to the procedures of the Structural Approach to Theory of Social Representations. In turn, the analysis of data obtained through the interview and reading the documents followed the guidelines of the Content Analysis method. The theoretical and methodological basis of this research was the Theory of Social Representations and critical approach to environmental education. Thus, the results obtained in the investigation allowed us to identify the social representations of EA of participants; confirm that such representations are being targeted in their pedagogical practices that are characterized as conservative. Also confirm that the teaching documents of the surveyed network are in line with the official documents on EA; the AE actions developed in the network are referenced in the teaching documents of the network and in the official documents of EA and the EA practices of survey participants teachers relate directly with their social representations on Environmental Education.

This masters thesis discusses the studying and the teaching of drama and its implications among teenagers of the contemporary world. This paper also analyses an extracurricular project entitled Drama in the development of citizenship , which was carried out in the public state school Berilo Wanderley in Natal/RN, between 1999 and 2005 with high school students. It comprises a case study that aimed at understanding how and why they chose to take drama classes outside of the school curriculum and even after they graduated, some of them never left the school project and even started participating in the cultural and artistic context of the city of Natal quite actively, both as part of an audience as well as on artistic, political, social and pedagogical performance. The project was high significant for its participants, for the school and for the community, by creating a sense of recognition of the relevance of the pedagogical and artistic production in the public school, as it managed to yield knowledge that helped students to understand the values of group work, sharing information, collaborative assessment and, most of all, to engender actions of protagonism by the teenagers themselves within their social environments. The empirical process developed is placed in a contemporary historical context where educational paradigms shifts occur, and where categories of youth empowerment and protagonism are fundamental to the educational process in the 21st century. The objective of this study is to reflect upon the pedagogical dimension of drama classes for teenagers, aiming at providing further discussions on the role of acting classes in the construction of the personality among youngsters, thus hoping to contribute to other teaching practices, including drama and other subjects of general education

à hoje em dia inquestionada a importância da inovação para o crescimento económico e para o desenvolvimento sustentado das empresas e da sociedade. Sendo verdade que o desempenho em termos de inovação das empresas, regiões ou países está condicionado por múltiplos factores de contexto, não é menos verdade que o verdadeiro motor desse desempenho são as iniciativas das empresas e das organizações. O sucesso dos projectos de inovação depende de um elevado número de factores, alguns dos quais são frequentemente negligenciados aquando da análise dos processos de inovação, tais como alianças estratégicas e parcerias, estrutura dos consórcios, protecção dos direitos de propriedade intelectual, estratégias de exploração dos resultados dos projectos, etc. Este artigo centra-se na análise e caracterização do processo de inovação em projectos de desenvolvimento de novos produtos levados a cabo por consórcios liderados por empresas industriais em Portugal. Após uma breve introdução ao problema, descreve-se de forma sucinta o enquadramento metodológico proposto e apresentam-se e discutem-se resultados obtidos através de um estudo conduzido pelo INESC Porto e pelo Observatório das Ciências e do Ensino Superior (OCES) do Ministério da Ciência, Inovação e Ensino Superior (MCIES).
