A crise na sociedade do trabalho e sua importância na contextualização dos conteúdos curriculares do ensino médio

This article has as objective to discuss some topics concerning the supposed crisis of the society of the work and its consequences for the debate in social sciences and also for the work category contextualization in the secondary school curriculum. As the work has represented an important explanation category for the classic social thought, the contemporary paradigm of deep metamorphoses in the world of the work and the advent of the new question (CASTELS, 1995; ROSANVALLON, 1995) backward the necessity to rethink the theoretical shades that base the interpretation of the social life on the current context, when the center position of the work is being questioned. Having taken some theoretical references from the sociology of the work, we search to delineate on a brief way the quarrel about the dimensions of the social and political phenomena these days and the importance of this debate on the contextualization of the secondary school curriculum contents.

Expectativas sobre os efeitos do uso de álcool e padrão de beber em alunos de ensino médio

Studies have shown that adolescents begin to make use of alcoholic beverages earlier and excessively, a behavior which has several negative consequences. Thus, the present study aims at investigating whether the expectations they have for the effects of alcohol consumption are high or low and if there is a relationship between expectation and consumption pattern. AUDIT and IECPA were applied as data collection instruments. The first indentifies the pattern of alcohol use and the second investigates the expectations the subjects have in relation to the use of alcohol. The results of this study, differently than others, do not evidence the positive relationship between binge-drinking and high expectations about the use of alcohol.

O modelo atômico de Bohr e as abordagens para seu ensino na escola média

The teaching of modern and contemporary Physics subjects in high school is indispensable and it was already justified by several researchers. Among the subjects which must be taught, there is, for instance, Bohr atomics model. However, as it was noticed in literature review, many didactic materials do not deal with this model adequately, since that they do not take into account Bohr ideas, which involved Planck studies on black-body radiation, Einsten theory for photoelectric effect, Rutherford experiences and atomics model and the empiric results upon the spectrums of chemical elements emission. From that, it is extremely important teaching through approaches which potentialize the learning of the model proposed by Niels Bohr. On the other hand, teachers from high schools cannot have clearness about which approaches can be applied for teaching the mentioned model. Thus, it is presented some possibilities for teaching Bohr atomics model, with examples and justifications for the use of each one. Special treatment was attributed to the teaching from Science History and Philosophy, from the reading of scientific diffusion and original scientific texts, from analogies, from comic strips and from computer simulations.

Atividades investigativas: o impacto na capacidade de argumentação em alunos do ensino médio sobre eletroquímica

The education research guidelines have shown the important contribution of the investigations that focus on analysis of the discursive dimension of teaching and learning of Science in actual classroom. An interesting proposal to analyze the effectiveness of an educational activity is to assess the potential of investigative activities in the development of argumentation in science classes. Several studies have taken into account the use of argument in the classroom as a way to provide students with new ways to know the science. Argument refers to the process of associating components that play a central role in the construction of explanations, models and theories. In order to investigate the potential of these activities took place the application of investigative activities with third-year high school students, recorded in audio and video, focusing on the development of the argument. The search, conducted ranks as a qualitative research with characteristics of a case study. The arguments collected during the activities contained the students' conceptions about the concepts discussed and all were recorded in audio and video. With the encouragement of the argument by the investigative activity we evaluate the learning experienced by the speech of students. It may be noted that students have appropriated the concept of oxidation involving electron transfer, thus the activity reached the goal, so that was planned, making it effective for the introduction of electrochemical concepts

Casos de ensino relacionados à educação física escolar: uma produção dos alunos do ensino médio

Teaching cases are records, through written narratives, of an academic episode or incident, they appear in educational scenery as a rich strategy not only for the teacher's conformation but also for their investigation. The bibliography shows that young students are still not very much investigated and it contributes to the establishment of negative images of this social subject. In this sense, the objective of this work is to analyze the stories and episodes, called teaching cases, in narrative style, written by students from High School about their physical education classes. The participants of this study are High School students from two public schools from two cities in the countryside of São Paulo state. The researcher stayed in the schools for nine months and in this meantime she made contact with the students, asking, for the ones who showed interest, the construction of teaching cases. For this interested students, the researcher explained researcher explained what teaching cases are, as well as, she presented a template to guide them in the production. At the end of this process, twenty teaching cases were delivered to the researcher. They were analyzed under the qualitative approach, valuing the expressive wealth in the narratives, complemented by the interviews with the authors. Inset the mosaic of narratives and interviews, showing a variety of experiences and possibilities of distance and approximation of the students to the physical education classes, we can indicate that from the 20 cases, only one was set as a total distance from the physical education classes (this is the student's situation since she was in the second grade from elementary school). Mentioning the positive experiences and the approximation to the physical education classes, the association of teaching cases and interviews showed that seven students lived the context and until today present an affective proximity to the classes. These evidences can help...

It wonders of the using of media blogs for High School students as articulators of the Portuguese Language contents' study. It is possible to verify that the blogs offer its own languages and the expression of knowledge and power. They put the high school student before the articulation of several cross-cutting themes that promotes the interdisciplinarity. It points the need of a teacher's support so in a matted discursive voices the student won't be distracted, drift and paraphrase, but the interpretation and "new" methods of reading and polysemy. The theoretical framework is composed by the authors Foucault, Pecheux, Orlandi and Coracini.
