Reflexões e contribuições para o ensino de gravitação clássica no nível médio

The subject of Classic Gravitation is part of the actual curriculum for High School in Brazil, and it is taught in the first year of that education level. This master thesis presents a research regarding the subject Classic Gravitation in High School. This research was based in two complementary guidelines of research and action. The first guideline was the analysis of 21 didactic books of physics which are the more frequently used in High School, in the city of Natal/RN. The second guideline, worked after being verified the most common deficiencies presents in the didactic books, was the elaboration, followed by a practical application, of a course suggesting how to approach that subject in the classroom. The Parâmetros Curriculares Nacionais para o Ensino Médio (National Curricular Parameters for High School PCNEM) defend that Classic Gravitation is very important in the student s formation and that its study helps the comprehension of many nature s phenomena. Because of this vision of that subject by the PCNEM, the 21 analyzed books were separated in two groups: the first one, containing 10 books, was edited before the spreading of PCNEM, and the second, with 11 books, after that spreading. Whatever the group to which the didactic books belonged, the great majority of them let that subject in a second plan; two of them even suggesting, in the teacher s orientations, that the subject Gravitation can be suppressed in case of insufficient time . These analyses points that the PCNEM had produced no changes in the conception of the authors that wrote books regarding that subject. To analyze the didactic books, we elaborated a script which was used as an analysis tool, in which we put in evidence the relative importance of the historic and philosophic contextualization of the subject, the quotidian experience of the students and the interdisciplinary approach, among other aspects. It became evident that the didactic books give very little emphasis to historic aspects of the knowledge construction, to the relations with the day-by-day questions and to the interdisciplinary character of the subject Gravitation. It calls attention the non concordance among the authors opinions regarding the necessary previous knowledge or prerequisites the students should fulfill in order to begin to study Gravitation. The course we elaborated was given to a group of teachers as well as to students. In those courses we treated theoretical and practical aspects and emphasized historical questions and the ones which are related to people s daily life. The course for teachers was realized as an extra-mural activity of the UFRN and was given by the author of this thesis at the Escola Estadual Francisco Ivo Cavalcanti (a state public school in Natal/RN). There were 23 teachers present, from several public schools and several fields of knowledge. The thesis supervisor and the master degree s colleagues of the author acted as collaborators , reporting the participants opinions and speeches. The course to the students, on the other hand, had the participation of 300 regular students who belonged to 6 different 1st year classes of the High School Escola Marista de Natal (RN), in which the author acts as a physics teacher. The student s course was realized as part of the regular curriculum activities, in which three classes stood under the responsibility of the author and other three classes in charge of another Marista s teacher, who participated as a collaborator . The teacher s course as well as the students one were given in two stages, with five hours each. The first stage was divided in two moments, the first one focused on the survey of the spontaneous conceptions about gravitation, in which we worked basically with experiments of free throwing and pendulum, and the second one focused in theoretical presentations and quarrels about universe s models. In the second stage of the course we improved the study of Kepler s laws and the Newton s Universal Gravitation law, and we used as motivating tools some practices involving the construction of the solar system in scale. As instruments for evaluating both courses we used questionnaires and reported the speeches with participants opinions, beyond usual written evaluations in the course for the students. The teachers who participated in the course showed very good wills in realizing interdisciplinary practices; nevertheless, according their own speeches, they frequently came across the difficulty of how to do . From the experience we had in both courses, we conclude that the approach we propose hear to the teaching of the subject Classic Gravitation , supported on the tripod theory, practice and historical and philosophical aspects, is viable and effective. One hopes that this research may contribute in the formation of a opinion, among the teachers, concerning how to approach the subject of Classic Gravitation, and may offer suggestions in order those who want to apply that approach may develop classroom practices aiming to improve the teaching of that subject, which has a singular importance in the formation of High School students

Análise qualitativa do conteúdo ministrado na disciplina de bioética nas faculdades de odontologia brasileiras

The study consists on a qualitative analysis of content ministered by Bioethical discipline on Brazilian Dental Schools. Data collect occurred by semi-structured questioners send by e-mail and correspondence. It was used content analysis by categorical analysis technique, according to Bardin. Among 182 Schools, just 57 (31.3%) shows Bioethical Discipline. It was observed that the discipline is ministered on the first or last year of course generally. Principal subjects broached are bioethical dilemma (76.3%) with polemics questions and others actual like abortion, clone, organs transplant, attendance of patient porter of HIV and bioethical historic (65.8%), bioethical fundaments, principles and models (57.9%). 84.4% researched professors, said that bioethical discipline awake interesting on students because it actual and it's face to patient-professional relation too. It was possible to conclude that bioethical discipline treat in its content some actual and polemic themes that influence dental surgeon formation because promote him conscience and responsibility of him role front attention at oral health, and so, this discipline should be implanted, specifically in the first year of all Dentistry graduation courses.

Surveillance Programme for Healthcare Associated Infections in the State of São Paulo, Brazil. Implementation and the first three years' results

Governmental programmes should be developed to collect and analyse data on healthcare associated infections (HAIs). This study describes the healthcare setting and both the implementation and preliminary results of the Programme for Surveillance of Healthcare Associated Infections in the State of São Paulo (PSHAISP), Brazil, from 2004 to 2006. Characterisation of the healthcare settings was carried out using a national database. The PSHAISP was implemented using components for acute care hospitals (ACH) or long term care facilities (LTCF). The components for surveillance in ACHs were surgical unit, intensive care unit and high risk nursery. The infections included in the surveillance were surgical site infection in clean surgery, pneumonia, urinary tract infection and device-associated bloodstream infections. Regarding the LTCF component, pneumonia, scabies and gastroenteritis in all inpatients were reported. In the first year of the programme there were 457 participating healthcare settings, representing 51.1% of the hospitals registered in the national database. Data obtained in this study are the initial results and have already been used for education in both surveillance and the prevention of HAI. The results of the PSHAISP show that it is feasible to collect data from a large number of hospitals. This will assist the State of São Paulo in assessing the impact of interventions and in resource allocation. (C) 2010 The Hospital Infection Society. Published by Elsevier Ltd. All rights reserved.

Dornase alfa improves the health-related quality of life among Brazilian patients with cystic fibrosis - A one-year prospective study

Background: Health-related quality of life (HRQOL) measurements provide valuable information about the psychological and social impact of treatment on patients with cystic fibrosis (CF). This study evaluated the HRQOL of Brazilian patients with CF and assessed the changes in HRQOL domains over 1 year after dornase alfa (Pulmozyme) introduction. Patients and Methods: One hundred fifty-six stable patients with CF and 89 caregivers answered the Portuguese-validated version of the Cystic Fibrosis Questionnaire-Revised (CFQ-R) at baseline (T 0), and at 3 (T 1), 6 (T 2), 9 (T 3), and 12 (T 4) months of follow-up. Eighteen patientswere excluded because they did not fulfill the inclusion criteria. The patients were analyzed in two groups: those aged 6-11 years and those aged 14 years and older. ANOVA for observed repeated results and the last observation carried forward (LOCF) method for missing data were used for the statistical analysis. Results: After 1 year of follow-up, there was significant improvement in respiratory symptoms (T 4-T 0=8.1; 95% confidence interval (95% CI)=[2.1;14.0]; effect size (ES)=0.35; P<0.001), Emotional Functioning (T 4-T 0=5.6; 95% CI=[1.1;10.1]; ES=0.31; P<0.05), Social Functioning (T 4-T 0=6.0; 95% CI=[1.3;11.7]; ES=0.31; P<0.05), Body Image (T 4-T 0=11.9; 95% CI=[4.1;19.7]; ES=0.42; P<0.05), and Treatment Burden (T 4-T 0=5.3; 95% CI=[0.3;10.3]; ES=0.24; P<0.05) domains in the younger group. A significant improvement in Role Functioning (T 4-T 0=6.1; 95% CI=[1.1;11.1]; ES=0.40; P<0.05), Body Image (T 4-T 0=12.6; 95% CI=[3.5;21.7]; ES=0.46; P<0.05), and Weight (T 4-T 0=11.7; 95% CI=[1.8;21.6]; ES=0.40; P<0.05) was obtained in the older group. The caregivers' CFQ-R showed improvements in the Digestive Symptoms (T 4-T 0=5.5; 95% CI=[1.5;9.4]; ES=0.30; P<0.05), Respiratory Symptoms (T 4-T 0=7.6; 95% CI=[3.9;11.4]; ES=0.48; P<0.05), and Weight (T 4-T 0=10.1; 95% CI=[1.6;18.6]; ES=0.26; P<0.05) domains. Conclusion: The introduction of dornase alfa improved the HRQL of the patients with CF during the first year of treatment. © 2010 Wiley-Liss, Inc.

Avaliação da aprendizagem em língua inglesa no primeiro ano do ensino fundamental em escolas públicas do município de Castanhal (PA)

O presente estudo investiga as práticas avaliativas em inglês como Língua Estrangeira para Crianças (LEC) no primeiro ano do ensino fundamental das escolas públicas no município de Castanhal, PA. A pesquisa teve como objetivo analisar quais as orientações contidas nos documentos oficiais municipais no que diz respeito ao ensino e à avaliação em LEC, descrever as práticas avaliativas desenvolvidas pelos docentes nesse contexto, analisar a integração dessas práticas com os objetivos de ensino e aprendizagem de LEC e indicar pistas que possam, teórica e metodologicamente, tornar essas práticas mais eficazes. Para alcançar os objetivos propostos, foi realizada uma pesquisa qualitativa de caráter documental, na qual foram analisados os documentos oficiais que norteiam o ensino e a avaliação em LEC no município, 220 relatórios de desenvolvimento, que são o instrumento de avaliação preconizado para esse nível da escolaridade, além de entrevistas e questionários com 14 docentes que atuam nesse contexto. O referencial teórico sustenta-se nas contribuições de Cameron (2001), Strecht-Ribeiro (2005) e Scott e Ytreberg (1990) sobre o ensino-aprendizagem de LEC, bem como na discussão de alguns aspectos da avaliação da aprendizagem (HADJI, 1994; 2007; BONNIOL e VIAL, 2001; FERNANDES, 2009; PERRENOUD, 1999) e da avaliação da aprendizagem em LEC (MCKAY, 2006; IOANNOU-GEORGIOU, 2011; SHAABAN, 2001). Para a análise dos dados obtidos, foi utilizada a técnica de Análise de Conteúdo (ROSA, 2013). Os resultados da análise indicam uma ausência de coerência entre as práticas avaliativas e os objetivos e princípios do ensino de LEC. Os dados revelam ainda a falta de formação para ensinar, avaliar e elaborar programas de LEC, aliada a uma já conhecida tendência em se priorizar aspectos estruturais no ensino de línguas estrangeiras, em detrimento de atividades comunicativas. Por fim, este trabalho mostra a necessidade de promover outras pesquisas que investiguem as práticas avaliativas em LEC e, da urgência em se definir diretrizes oficiais nacionais para o ensino e avaliação que levem em consideração as características e necessidades das crianças nesse contexto.

Annual Report of Nebraska's Reading First

Thi report summarizes the results of the first year of the Reading First Initiative in Nebraska. Results show that teachers and schools have made a real effort to change. Student performance in the earlier grades has shown great promise for the following years, however, growth in fluency and comprehension in grades 2 and 3 were not as impressive and require additional attention. Overall, students make at least a year’s progress in most schools and most demographic groups. Schools can make much better use of the data they were collecting and need further direction in this area The assessment results were triangulated by observations in the classrooms, interviews, and teacher responses to professional development- teachers know how to teach PA and the alphabetic principle but were still struggling with: finding time and effective strategies for fluency training teaching comprehension strategies teaching self monitoring. Growing gaps for SPED, Ethnic minorities, and ELL students suggest an emphasis on the secondary and tertiary levels of intervention in the schools.
