Este trabalho investiga o desempenho lingüístico de dois grupos de adolescentes entre 10 e 18 anos, segundo grau de escolaridade e estrato sócio-econômico. Seu principal objetivo é verificar o grau de conformidade alcançado por ambos à norma adulta de prestigio, considerando-se unicamente variantes fonológicas e avaliar, além disso, o papel da escola no ensino de habilidades consideradas necessárias à aquisição de um conjunto consistente de variantes sócio-culturais.

Trata-se de uma reflexão sobre o vocabulário de áreas disciplinares, estudadas na escola do segundo grau e desta para a universidade. Com base nos princípios teóricos da lexicologia e da definição terminológica, pretende-se mostrar a necessidade de sistematização de atividades pedagógicas, orientadas para contextos ideológicos. No exemplo dado, foram tomados os critérios de tempo e lugar, trabalhados na área de História, para demonstrar como as definições podem ser veiculadas no universo de conhecimento.

Um experimento de campo com diferentes níveis de irrigação e nitrogênio foi conduzido no Centro de Ciências Agrárias da Universidade Federal de Alagoas com o objetivo de determinar a função de produção e as isoquantas de produtividade agrícola da cana-de-açúcar com base nas lâminas de irrigação e doses de nitrogênio (N). A precipitação pluvial efetiva durante o ciclo de produção foi 1.037 mm e a lâmina de irrigação bruta máxima foi 873 mm. A produtividade agrícola ficou entre 118 e 188 Mg ha-1, média de 160 Mg ha-1. Na isoquanta da produtividade agrícola média da cana-de-açúcar, a taxa marginal de substituição de água por N é 0,36 kg mm-1 (na interseção das retas de 25 kg de N ha-1 e 760 mm de irrigação) e infinita (na interseção das retas de 125 kg de N ha-1 e 390 mm de irrigação). A quantidade de água e nitrogênio de menor custo para produzir 160 Mg ha-1 foi 390 mm de irrigação e 112 kg de N ha-1. A regressão polinomial de segundo grau apresentou ajuste médio (r2 = 62%) para a produtividade agrícola em relação às lâminas de irrigação e doses de nitrogênio. A resposta da cana-de-açúcar à adubação nitrogenada aumenta em proporção direta com disponibilidade hídrica do solo.

This research project aims to determine the main way that the inclusion of topics of history and philosophy of science education activities aimed at high school, influence the process of teaching and learning of chemistry. The subject of research will be a teacher, undergraduate student in chemistry and public school students that the teaching units developed will be applied. The literature presents a large of research indicating the need to include these topics in education and present the results of large withdrawals of original sources of the development of scientific knowledge. Despite of the large number of these works are not very common reports of application of the results of these studies on activities of the classroom, which reinforces the importance of this study

This study sought to raise the water issue is addressed in the teaching of chemistry in public schools through the notebooks Curricular Proposal of the State of Sao Paulo. First we tried to do a survey of knowledge related to construction of the concept of historical perspective, the physical and chemical properties, their importance to man and the particulars of the national curriculum for this subject. The methodology used was qualitative, descriptive and documentary. We analyzed the books for the first, second and third marking periods and the three series (the 4th book had not yet been distributed). As expected the first scenario, the proposed curriculum addresses the topic in greater depth in only one of the notebooks of the second year of high school. The approaches are no longer linked to health issues and the environment, cross-cutting issues considered by the NCP and important for students to make associations between the chemical content and their daily lives. We conclude that the contract should be evaluated by teachers and that their use should be involved in drawing up a plan that takes into account the aspects that seem incomplete. We also emphasize that although the proposal is interesting from the standpoint of teaching, teachers need training to its full use in the classroom

Burns are frequent accidents, and they are among the major causes of morbidity and mortality in our society. In Brazil, statistical data on such lesions are relatively scarce, and they are concentrated in a few treatment centers. Data on such accidents allow for specific care to be timely and properly taken in order to provide patients with a better prognosis, in addition to enabling the development of prevention programs as well as fire-prevention safety laws. To characterize the epidemiological profile of users at the Burn Treatment Unit of Bauru State Hospital. Collection of epidemiological data through the e-pront system and from charts of burned inpatients from April 2005 to April 2010. During the studied period, 906 hospitalizations of burned patients occurred, with an annual average of 181.2 individuals. Their mean age was 28.4 years, with a predominance of males. The mean hospitalization period was of 27.6 days, with a median of 16 days and a maximum of 216 days; 14.7% developed to death, with the highest mortality rate in the first two weeks of hospitalization. Second-degree burns were the most frequent; 36.8% of the patients burned less than 10% of their body surface, and there was a gradual frequency reduction when a larger burned surface was taken into account; the greater the affected areas, the higher the number of deaths; 91% resulted from thermal agents, 6% from electric and 2% from chemical agents; scalding was the major cause among all agents, followed by alcohol associated with fire and direct flame. The major area affected areas were the upper limbs. The study shows the need for educational and preventive measures, particularly for the young adult population, by means of educational programs and prevention campaigns

This study shows new alternatives to the teaching of chemistry in high school and wants to be an aid to the teacher at the time of the planning of lessons and a way to help students improve their performance in this discipline. The central issue is the exploration of differentiated teaching strategies for a just end: improvement of education in chemistry. To reach the main point is to undertake a survey of the most important issues for students and teachers, and from there many teaching strategies are suggested to help in understanding the contents studied. The idea is to propose strategies that may be of interest to students of chemistry, stimulating the curiosity of wanting to know more about a certain content that is being studied in the classroom. This study shows that chemistry is not boring, is not as difficult as it seems, and everyone can indeed take pleasure in studying a world as real and so fascinating, if you understand the facts
