O uso do computador no processo de ensino e aprendizagem: questões de representação social

This paper presents the results of a study aimed at identifying and analyzing the theoretical and methodological principles that guide the practice of teachers in the early years of computer use in the teaching and learning. Specific objectives we seek to identify and analyze the social representations of teachers on the use of computers in teaching and learning. The research took a qualitative approach with a descriptive-explanatory and owned two phases of data collection: a) a questionnaire b) monitoring the daily practice of teachers in a selected school and semi-structured interview. The analysis of data was done through content analysis. Through the interrelationship of the data in the questionnaire, observation and interview, we found that the teachers surveyed have an address that does not match the teaching practice in the use of computers in the educational process. The theoretical expressed by teachers participating in the research meets constructivist beliefs and / or sociointeractionists but teaching practice thins primarily to behavioral assumptions. Observe social issues of representation when the speeches of the participating teachers did not correspond to their practices. Associated with this or as a cause of these conditions have failure, inadequacy or absence of teacher training for the use of computers in the educational process leading to under-utilization of this resource.

Avaliação de um curso sobre internet para terceira idade

The aim of this study was to evaluate the learning of Senior Citizens after a face-to-face course with the goal of teaching them how to use the internet. The study population was composed of people (n=18), of both genders, aged 50 years or over, from the open university for Senior Citizens UNATI (“Universidade Aberta da Terceira Idade” in Portuguese) at Araraquara. Two hour classes weekly were taught in the computer laboratory - LDI in Portuguese located in the School of Dentistry in Araraquara. The course program content covered the use of e-mail and researches in sites. In order to evaluate the learning acquired, a self-evaluation questionnaire was applied in twice (before and after the course), which enabled the development of students concerning their knowledge and skill in the topics approached in classes. Descriptive statistical analysis was performed. The average performance of participants was calculated per point and interval of confidence of 95% (IC95%) in the beginning and in the end of the course. Comparison between the averages was performed by using the paired Student’s-t test. The level of significance adopted was 5%. It was observed that the students’ learning about computer use improved significantly after the course (Student’s-t test: -5.360, p<0.001, p2=0.628, =0,999), however, 72.2% of them reported that they did not know how to attach a file to a message to be sent by e-mail, as well as having no or little skill to perform this activity. It was concluded that the evaluated course improved the participants knowledge and skills in computer use.

High blood pressure and sedentary behavior in adolescents are associated even after controlling for confounding factors

The aim of this study was to determine whether high blood pressure (HBP) is associated with sedentary behavior in young people even after controlling for potential confounders (gender, age, socioeconomic level, tobacco, alcohol, obesity and physical activity). In this epidemiological study, 1231 adolescents were evaluated. Blood pressure was measured with an oscillometric device and waist circumference with an inextensible tape. Sedentary behavior (watching television, computer use and playing video games) and physical activity were assessed by a questionnaire. We used mean and standard deviation to describe the statistical analysis, and the association between HBP and sedentary behavior was assessed by the chi-squared test. Binary logistic regression was used to observe the magnitude of association and cluster analyses (sedentary behavior and abdominal obesity; sedentary behavior and physical inactivity). HBP was associated with sedentary behaviors [odds ratio (OR) = 2.21, 95% confidence interval (CI) = 1.41-3.96], even after controlling for various confounders (OR = 1.68, CI = 1.03-2.75). In cluster analysis the combination of sedentary behavior and elevated abdominal obesity contributed significantly to an increased likelihood of having HBP (OR = 13.51, CI 7.21-23.97). Sedentary behavior was associated with HBP, and excess fat in the abdominal region contributed to the modulation of this association.

A formação continuada, o uso do computador e as aulas de ciências nos anos iniciais do ensino fundamental

The present article aims to discuss a process of continuing education which was focused on Science teaching and computer use considering the school as the locus of training. This process was intended for teachers who taught in the first years of Primary School. The research was developed with a qualitative approach, focusing on participant observation. It was aimed to characterize the educational practices, considering the elaboration of scientific knowledge, the development of experimental activities and the educational possibilities of the Information and Communication Technologies. The results reveal the involvement of the group in an attitude of research and reflection, and the utilization of collective spaces for constant discussion regarding the issues of classroom and teaching action.

O auxílio do software Geogebra na aquisição do conhecimento da função seno

This article aims to reflect on the qualitative analysis regarding the modification and the acquisition of new knowledge, as well as to identify the contribution of computer use in an intervention activity. It was used content analysis and it was created categories and units of analysis and from the frames containing the analysis of the categories it was randomly chosen four groups which led to their evaluation. Concerning to such frames of analysis and evaluation of the frequency of the records it was structured a metatext. The result of the analysis has shown the students' difficulty to realize their records, to express their interpretations and understandings in their mathematical activities by using the English language. It was noticed that the activity performed using the software Geogebra, based on the constructionist view, make possible the students to identify the modification and acquisition of new concepts.

Analysis of land use and occupancy in permanent preservation areas according to the hydrography of Ribeirão Água Fria - Bofete, SP - Brazil

Os conflitos de uso são determinados pelas ocupações inadequadas do solo, como é o caso de ocupação do solo dentro de áreas de preservação permanente. O presente trabalho teve como objetivos determinar as classes de uso do solo e se há conflitos dentro de áreas de preservação permanente ao longo da rede de drenagem da microbacia do Ribeirão Água Fria, município de Bofete (SP). Situa-se geograficamente entre as coordenadas: 48°09'30 a 48°18'30 de longitude WGr., 22°58'30 a 23°04'30 de latitude sul com uma área de 15.242,84 ha. O mapa de uso do solo foi elaborado por meio da interpretação diretamente na tela do computador de imagem digital de satélite. Nos dados orbitais, a área de estudo está inserida no quadrante A, da imagem TM/Landsat-5, órbita 220, ponto 76, passagem de 8/09/2007. O Sistema de Informação Geográfica empregado foi o Cartalinx. As áreas de conflito da microbacia foram obtidas a partir do cruzamento entre os mapas de uso do solo e de APPs. Os resultados permitiram concluir que mais da metade da área (51,09%) está ocupada por pastagens, reflexo de solos arenosos e de baixa fertilidade. Constatou-se, ainda, que apesar de quase metade da microbacia estar coberta com algum tipo de vegetação (48,78% de mata natural/reflorestamento), possui aproximadamente um terço das áreas de preservação permanente utilizadas inadequadamente por pastagens (88,15%), reflorestamento (10,42%) e solo exposto (1,43%), totalizando 343,07 ha de áreas conflitantes em um total de 993,26 ha de APPs.
