A teaching-learning sequence of colour informed by history and philosophy of science

In this work, we present a teaching-learning sequence on colour intended to a pre-service elementary teacher programme informed by History and Philosophy of Science. Working in a socio-constructivist framework, we made an excursion on the history of colour. Our excursion through history of colour, as well as the reported misconception on colour helps us to inform the constructions of the teaching-learning sequence. We apply a questionnaire both before and after each of the two cycles of action-research in order to assess students’ knowledge evolution on colour and to evaluate our teaching-learning sequence. Finally, we present a discussion on the persistence of deep-rooted alternative conceptions.

Teaching and learning with social software in higher education: content management systems integrated with Web-based applications as a key factor for success

The change of paradigm imposed by the Bologna process, in which the student will be responsible for their own learning, and the presence of a new generation of students with higher technological skills, represent a huge challenge for higher education institutions. The use of new Web Social concepts in teaching process, supported by applications commonly called Web 2.0, with which these new students feel at ease, can bring benefits in terms of motivation and the frequency and quality of students' involvement in academic activities. An e-learning platform with web-based applications as a complement can significantly contribute to the development of different skills in higher education students, covering areas which are usually in deficit.

Agreement between premortem and postmortem diagnoses in patients with acquired immunodeficiency syndrome observed at a brazilian teaching hospital

Acquired immunodeficiency syndrome (AIDS) is one of the main causes of death in adults worldwide. More commonly than in the general population, in patients with AIDS there is substantial disagreement between causes of death which are clinically suspected and those established by postmortem examination. The findings of 52 postmortem examinations were compared to the premortem (clinical) diagnoses, and there was 46% agreement between them. Fifty two percent of the patients had more than one postmortem diagnosis, and 48% had at least one AIDS-related disease not suspected clinically. Cytomegalovirus infection was the commonest (30.7%) autopsy finding, but not a single case had been suspected premortem. Bacterial infection, tuberculosis, and histoplasmosis were also common, sometimes not previously suspected, postmortem findings. This study shows that multiple infections occur simultaneously in AIDS patients, and that many among them are never suspected before the postmortem examination. These findings suggest that an aggressive investigation of infections and cancers should be done in patients with AIDS, particularly in those who do not respond to therapy of an already recognized condition

EXPERIENCE IN THE EVALUATION OF CHILDREN WITH HEPATOSPLENOMEGALY AT A TEACHING AMBULATORY, SÃO PAULO, BRAZIL

Objectives: Describe cases of children with hepatosplenomegaly (HS) attended at the General Pediatric Teaching Ambulatory (AGER) of Instituto da Criança, São Paulo, identifying the main causes, evolution, necessity for hospitalization and/or referral to specialists. Methodology: Retrospective analysis of the records of children presenting HS on admission at AGER from September 1, 1993 to August 31, 1996. Results: Of the 89 children included (age range, 1 to 148 months; median, 24 months), 64 (72%) were referred from other services for HS investigation. Most common presenting complaints were: fever - 39 (44%); pallor - 26 (29%); weight loss - 21 (24%) and jaundice - 14 (16%). Main alterations noticed on physical examination were: pallor - 47 (53%) and short stature - 17 (19%). Anemia was diagnosed in 70 children (79%); 35 children (39%) had infections; 7 (8%) metabolic disorders and 5 (6%) neoplastic disorders. The most frequent infections were of the urinary tract - 9 (10%) and hepatitis A - 6 (7%).Thirty six children (40%) were referred to specialists, 17 of which were already diagnosed. Conclusions: Most of the children with HS present deficiency anemia associated with infections which the general pediatrician is able to diagnose. Persistence of unexplained HS for more than 2 months, especially when there is substantial volume enlargement or alteration in the organs consistency, is an indication for referral to specialists.

As representações dos professores acerca da participação de alunos com necessidades educativas especiais em diversas atividades escolares

Os paradigmas concernentes à educação e ao atendimento de crianças com necessidades educativas especiais têm evoluído ao longo do tempo. De facto, se no paradigma da segregação o foco de incapacidade se situava no indivíduo, com o paradigma da inclusão o foco desloca-se para o ambiente, na medida em que este se deve organizar e preparar para dar resposta aos indivíduos com incapacidade. Por conseguinte, o meio deve assumir-se como facilitador à participação de todas as crianças. Tal fundamento comporta desafios para os professores e educadores, aos quais compete identificar as pressões de exclusão que inibem a participação plena de todos os alunos em todas as atividades inerentes ao meio escolar e acionar os suportes necessários para que tal não suceda. Com a realização deste estudo pretendemos conhecer de modo mais aprofundado as representações dos professores acerca da participação de alunos com diferentes tipos de incapacidade em variadas atividades e contextos escolares, identificando barreiras e facilitadores à sua participação e analisando os possíveis contributos pessoais dos professores para incrementar o nível de participação dos alunos com incapacidade em atividades inerentes ao meio escolar. O estudo operacionalizou-se através da aplicação de um inquérito por questionário, destinado a professores de todos os níveis de ensino e grupos de recrutamento. Através da aplicação deste instrumento, procurámos obter informações sobre os inquiridos, as representações dos professores acerca da participação de alunos com diferentes tipos de incapacidade em diversas atividades escolares, e, por fim, possíveis contributos para incrementar o nível de participação desses mesmos alunos. Os resultados sugerem que o tipo de incapacidade apresentado pelo aluno influencia as expetativas de participação de educadores e professores do ensino regular e da educação especial. Contudo, não confirmámos a existência de diferenças estatisticamente significativas entre os dois grupos de professores. No que concerne a possíveis contributos para incrementar a participação de alunos com incapacidade em diversas atividades escolares, identificámos a necessidade de se fomentar e desenvolver uma cultura de inclusão na escola.

Defining health law or the edgewood syndrome

ABSTRACT - The authors’ main purpose is to present ideas on defining Health Law by highlighting the particularities of the field of Health Law as well as of the teaching of this legal branch, hoping to contribute to the maturity and academic recognition of Health Law, not only as a very rich legal field but also as a powerful social instrument in the fulfillment of fundamental human rights. The authors defend that Health Law has several characteristics that distinguish it from traditional branches of law such as its complexity and multidisciplinary nature. The study of Health Law normally covers issues such as access to care, health systems organization, patients’ rights, health professionals’ rights and duties, strict liability, healthcare contracts between institutions and professionals, medical data protection and confidentiality, informed consent and professional secrecy, crossing different legal fields including administrative, antitrust, constitutional, contract, corporate, criminal, environmental, food and drug, intellectual property, insurance, international and supranational, labor/employment, property, taxation, and tort law. This is one of the reasons why teaching Health Law presents a challenge to the teacher, which will have to find the programs, content and methods appropriate to the profile of recipients which are normally non jurists and the needs of a multidisciplinary curricula. By describing academic definitions of Health Law as analogous to Edgewood, a fiction house which has a different architectural style in each of its walls, the authors try to describe which elements should compose a more comprehensive definition. In this article Biolaw, Bioethics and Human Rights are defined as complements to a definition of Health Law: Biolaw because it is the legal field that treats the social consequences that arise from technological advances in health and life sciences; Bioethics which evolutions normally influence the shape of the legal framework of Health; and, finally Human Rights theory and declarations are outlined as having always been historically linked to medicine and health, being the umbrella that must cover all the issues raised in the area of Health Law. To complete this brief incursion on the definition on Health Law the authors end by giving note of the complex relations between this field of Law and Public Health. Dealing more specifically on laws adopted by governments to provide important health services and regulate industries and individual conduct that affect the health of the populations, this aspect of Health Law requires special attention to avoid an imbalance between public powers and individual freedoms. The authors conclude that public trust in any health system is essentially sustained by developing health structures which are consistent with essential fundamental rights, such as the universal right to access health care, and that the study of Health Law can contribute with important insights into both health structures and fundamental rights in order to foster a health system that respects the Rule of Law.-------------------------- RESUMO – O objectivo principal dos autores é apresentar ideias sobre a definição de Direito da Saúde, destacando as particularidades desta área do direito, bem como do ensino deste ramo jurídico, na esperança de contribuir para a maturidade e para o reconhecimento académico do mesmo, não só como um campo juridicamente muito rico, mas, também, como um poderoso instrumento social no cumprimento dos direitos humanos fundamentais. Os autores defendem que o Direito da Saúde tem diversas características que o distinguem dos ramos tradicionais do direito, como a sua complexidade e natureza multidisciplinar. O estudo do Direito da Saúde abrangendo normalmente questões como o acesso aos cuidados, a organização dos sistemas de saúde, os direitos e deveres dos doentes e dos profissionais de saúde, a responsabilidade civil, os contratos entre instituições de saúde e profissionais, a protecção e a confidencialidade de dados clínicos, o consentimento informado e o sigilo profissional, implica uma abordagem transversal de diferentes áreas legais, incluindo os Direitos contratual, administrativo, antitrust, constitucional, empresarial, penal, ambiental, alimentar, farmacêutico, da propriedade intelectual, dos seguros, internacional e supranacional, trabalho, fiscal e penal. Esta é uma das razões pelas quais o ensino do Direito da Saúde representa um desafio para o professor, que terá de encontrar os programas, conteúdos e métodos adequados ao perfil dos destinatários, que são normalmente não juristas e às necessidades de um currículo multidisciplinar. Ao descrever as várias definições académicas de Direito da Saúde como análogas a Edgewood, uma casa de ficção que apresenta um estilo arquitectónico diferente em cada uma de suas paredes, os autores tentam encontrar os elementos que deveriam compor uma definição mais abrangente. No artigo, Biodireito, Bioética e Direitos Humanos são descritos como complementos de uma definição de Direito da Saúde: o Biodireito, dado que é o campo jurídico que trata as consequências sociais que surgem dos avanços tecnológicos na área da saúde e das ciências da vida; a Bioética cujas evoluções influenciam normalmente o quadro jurídico da Saúde; e, por fim, a teoria dos Direitos Humanos e as suas declarações as quais têm estado sempre historicamente ligadas à medicina e à saúde, devendo funcionar como pano de fundo de todas as questões levantadas na área do Direito da Saúde. Para finalizar a sua breve incursão sobre a definição de Direito da Saúde, os autores dão ainda nota das complexas relações entre este último e a Saúde Pública, onde se tratam mais especificamente as leis aprovadas pelos governos para regular os serviços de saúde, as indústrias e as condutas individuais que afectam a saúde das populações, aspecto do Direito da Saúde que requer uma atenção especial para evitar um desequilíbrio entre os poderes públicos e as liberdades individuais. Os autores concluem afirmando que a confiança do público em qualquer sistema de saúde é, essencialmente, sustentada pelo desenvolvimento de estruturas de saúde que sejam consistentes com o direito constitucional da saúde, tais como o direito universal ao acesso a cuidados de saúde, e que o estudo do Direito da Saúde pode contribuir com elementos

Standard commercial education robotic platform: intermediate solution to teaching robotics

Teaching robotics to students at the beginning of their studies has become a huge challenge. Simulation environments can be an effective solution to that challenge where students can interact with simulated robots and have the first contact with robotic constraints. From our previous experience with simulation environments it was possible to observe that students with lower background knowledge in robotics where able to deal with a limited number of constraints, implement a simulated robotic platform and study several sensors. The question is: after this first phase what should be the best approach? Should the student start developing their own hardware? Hardware development is a very important part of an engineer's education but it can also be a difficult phase that could lead to discouragement and loss of motivation in some students. Considering the previous constraints and first year engineering students’ high abandonment rate it is important to develop teaching strategies to deal with this problem in a feasible way. The solution that we propose is the integration of a low-cost standard robotic platform WowWee Rovio as an intermediate solution between the simulation phase and the stage where the students can develop their own robots. This approach will allow the students to keep working in robotic areas such as: cooperative behaviour, perception, navigation and data fusion. The propose approach proved to be a motivation step not only for the students but also for the teachers. Students and teachers were able to reach an agreement between the level of demand imposed by the teachers and satisfaction/motivation of the students.

Teaching accounting and management through business simulation

Everyday accounting and management teachers face the challenge of creating learning environments that motivate students. This chapter describes the Business Simulation (BS) experience that has taken place at the Polytechnic Institute of Porto, Institute of Accounting and Administration (IPP/ISCAP). The chapter presents students’ perceptions about the course and the teaching/learning approach. The results show that pedagogical methods used (competency-oriented), generic competencies (cooperation and group work), and interpersonal skills (organisational and communication skills) are relevant for future accounting professionals. In addition, positive remarks and possible constraints based on observation, staff meetings, and past research are reported. The chapter concludes with some recommendations from the project implementation

Candida bloodstream infection: data from a teaching hospital in Mato Grosso do Sul, Brazil

The incidence of Candida bloodstream infection has increased over the past years. In the Center-West region of Brazil, data on candidemia are scarce. This paper reports a retrospective analysis of 96 cases of Candida bloodstream infection at a Brazilian tertiary-care teaching hospital in the state of Mato Grosso do Sul, from January 1998 to December 2006. Demographic, clinical and laboratory data were collected from medical records and from the hospital's laboratory database. Patients' ages ranged from three days to 92 years, with 53 (55.2%) adults and 43 (44.8%) children. Of the latter, 25 (58.1%) were newborns. The risk conditions most often found were: long period of hospitalization, utilization of venous central catheter, and previous use of antibiotics. Fifty-eight (60.4%) patients died during the hospitalization period and eight (13.7%) of them died 30 days after the diagnosis of candidemia. Candida albicans (45.8%) was the most prevalent species, followed by C. parapsilosis (34.4%), C. tropicalis (14.6%) and C. glabrata (5.2%). This is the first report of Candida bloodstream infection in the state of Mato Grosso do Sul and it highlights the importance of considering the possibility of invasive Candida infection in patients exposed to risk factors, particularly among neonates and the elderly.

Rapid HIV diagnostic test in undocumented pregnant women applied at an inner-city teaching hospital

A significant number of Brazilian gestational-age women are still not tested for HIV, representing a high risk of transmission to their newborns. The current study sought to identify the number of pregnant women with no previous testing or undocumented for HIV referred to the Gynecology and Obstetrics Department of a Regional Teaching Hospital and included diagnosis of HIV infection determined by a rapid test and perinatal transmission in pregnancy. Medical records of all pregnant women admitted to hospital from January 2001 to December 2005 were reviewed. Pregnant women without HIV results were submitted to a rapid HIV test. Those who tested positive were further tested by ELISA and confirmed by indirect immunofluorescence assay (IIA) or Western blot (WB). The viral load from babies born to HIV-infected mothers was assessed by bDNA. Of the 16,424 pregnant women analyzed (6.6%), 1,089 were undocumented for HIV. Eleven women were positive in rapid testing and 10 were confirmed by ELISA, IIA or WB, with 0.9% seropositivity. Mother/infant pairs received zidovudine monotherapy prophylaxis and infant viral load was lower than 50 copies/mL. A higher number of pregnant women previously tested for HIV during antenatal care was verified, compared to that obtained nationwide.

Motivação de crianças e jovens para a prática vocal

Este relatório foi escrito no âmbito do estágio de Prática Educativa do Mestrado em Ensino da Educação Musical no Ensino Básico da Escola Superior de Educação do Instituto Politécnico do Porto. No primeiro capítulo encontra-se a caracterização dos contextos onde decorreu a Prática Educativa – escolas, turmas e comunidades educativas. O segundo capítulo engloba a reflexão e fundamentação das opções realizadas ao longo das três Práticas Educativas, que resultaram da negociação entre os ideais, os programas e as crianças e os jovens envolvidos, suas competências, anseios e motivações. O terceiro capítulo é dedicado ao projeto de investigação realizado sobre a motivação de crianças e jovens dos 2º e 3º ciclos do ensino básico para participarem em atividades de prática vocal extracurriculares e suas implicações para a Educação Musical na sala de aula. O contraste entre a motivação dos alunos na sala de aula e em atividades extracurriculares suscitou o desenvolvimento deste estudo em dois contextos: o Coro dos Meninos Cantores do Município da Trofa e o Clube de Canto da Escola Básica Augusto Gil. A reflexão sobre a Prática Educativa é um instrumento ao serviço dos professores que lhes permite avaliar, e avaliarem-se, e introduzir mais consciência e reflexividade na sua acção, com vista a melhorá-la continuamente e a torná-la pertinente para o percurso dos seus alunos num mundo em constante mudança.
