Os estilos cognitivos na educação escolar e sua dimensão conceitual como aporte teórico para a orientação do ensino e da aprendizagem

The contributions of studies on Cognitive Styles are presented and discussed in this text, introductory and conceptually, in order to clarify and facilitate the discussion within the school education. With the theoretical origin in the cognitive psychology, more specifically, in studies of human cognition in differential perspective, the Cognitive Styles, are constructs developed to describe perceptual characteristics of the individual called "Dependence and Independence Field." In the course of this conceptual construction it is evidenced that individual perceptions are part of a broad set of interrelated factors that reflect the level of psychological differentiation of individuals. The studies show subjects with different Cognitive Styles, that are distributed in a "continuum" in order to set up a statistical normality. Therein some educational implications related to the Cognitive Styles are evident in relation to how the students learn, how the teachers teach, to the formal education in itself and to the career plan. The Cognitive Styles has a broad spectrum of influence on the relationship established in the teaching-learning process. So, these concepts need urgently to be better understood in the context of education.

Ensino/aprendizagem de línguas em teletandem: espaços para autonomia e reflexão

This paper focuses on teletandem telecollaborative practice aiming at maximizing the teaching and learning foreign languages and investigating the spaces created for autonomy and reflection. Teletandem is a new context for learning languages in which students are paired up and help each other to learn the language. A qualitative ethnographic study was conducted from partnerships of Brazilian and American students. Based on e-mails, informal conversations, written reports and field notes taken at the Teletandem Laboratory, the results have shown that autonomy is gradually experienced by the partners as they take responsibility for their learning. Teletandem has also proved to be a context which fosters reflective actions.

Dificuldades de aprendizagem no contexto escolar: perspectivas para sua compreensão e superação

Inside my participation in the Teacher Education for the Educational Service of Students with Learning Disabilities extension project, which serves elementary school students which are presented by the school as students with learning desabilities in reading and writing, and in view of the large amount of material already published in relation of this issue it is necessary theoretical depth to better understand these entitled desabilities. Considering as how they are perceived and diagnosed by the school team, worked in the context of the classroom, understood by the parents and how these difficulties intefere in the lives of these students. It is known that due to these difficulties many students end up producing a feeling of school failure, a fact that leads, in many cases, to the dropout of these students. Given the need to discuss such pressing issues I present as the goal of this paper: characterize what learning to write and reading difficulties really are and speculate what are the possibilities of educational interventions within the school context to motivate and assist in overcoming the students‟ learning difficulties. Using resources such as a record notebook, activities already implemented, and leaning on the concept of school failure and learning difficulties, the metodology of this study is defined as documentary literature

A aprendizagem do desenho e da escrita: uma experiência com ideogramas japoneses no ensino fundamental

The aim of this paper is to gather research information and studies posted about the importance of social environment in the development of symbolic systems on children. Languages verbal, visual and written are interrelated representation systems, although each one has its own characteristics and elements. The objective of this paper is to elucidate the importance of linking the various existing types of language and therefore the importance of a coordinate approach also in the teaching-learning situations of these systems. The work also intends to disclose how thin is the line that separates writing of drawing, both of them as representative systems. As well as to show how visual information and language are intrinsically linked as thought happens by the connections between them. The work includes the report of an activity with Japanese ideograms done in the author's teacher's training at formal education. It also approaches pictographic, creative and poetic aspects of ideograms that brings up new ways of thinking and representing symbolically just like the methods of artistic language

Creation of Computer Simulation Model for Ecological Consequences Prognosis of Toxic Chemicals Discharge from Sunken on Baltic Sea Bottom Weapons"

This study summarises all the accessible data on old German chemical weapons dumped in the Baltic Sea. Mr. Goncharov formulated a concept of ecological impact evaluation of chemical warfare agents (CWA) on the marine environment and structured a simulation model adapted to the specific character of the hydrological condition and hydrobiological subjects of the Bornholm Deep. The mathematical model he has created describes the spreading of contaminants by currents and turbulence in the near bottom boundary layer. Parameters of CWA discharge through corrosion of canisters were given for various kinds of bottom sediments with allowance for current velocity. He created a method for integral estimations and a computer simulation model and completed a forecast for CWA "Mustard", which showed that in normal hydrometeorological conditions there are local toxic plumes drifting along the bottom for a distance of up to several kilometres. With storm winds the toxic plumes from separate canisters interflow and lengthen and can reach fishery areas near Bornholm Island. When salt water from the North Sea flows in, the length of toxic zones can increase up to and over 100 kilometres and toxic water masses can spread into the northern Baltic. On this basis, Mr. Goncharov drew up recommendations to reduce dangers for human ecology and proposed the creation of a special system for the forecasting and remote sensing of the environmental conditions of CWA burial places.

Faecal pellet production of copepoda collected in water depth up to 30 meters in the eastern Mediterranean Sea in Oktober 2008 during SES_GR2

Mesozooplankton is collected by vertical tows within the Black sea water body mass layer in the NE Aegean, using a WP-2 200 µm net equipped with a large non-filtering cod-end (10 l). Macrozooplankton organisms are removed using a 2000 µm net. A few unsorted animals (approximately 100) are placed inside several glass beaker of 250 ml filled with GF/F or 0.2 µm Nucleopore filtered seawater and with a 100 µm net placed 1 cm above the beaker bottom. Beakers are then placed in an incubator at natural light and maintaining the in situ temperature. After 1 hour pellets are separated from animals and placed in separated flasks and preserved with formalin. Pellets are counted and measured using an inverted microscope. Animals are scanned and counted using an image analysis system. Carbon- Specific faecal pellet production is calculated from a) faecal pellet production, b) individual carbon: Animals are scanned and their body area is measured using an image analysis system. Body volume is then calculated as an ellipsoid using the major and minor axis of an ellipse of same area as the body. Individual carbon is calculated from a carbon- total body volume of organisms (relationship obtained for the Mediterranean Sea by Alcaraz et al. (2003) divided by the total number of individuals scanned and c) faecal pellet carbon: Faecal pellet length and width is measured using an inverted microscope. Faecal pellet volume is calculated from length and width assuming cylindrical shape. Conversion of faecal pellet volume to carbon is done using values obtained in the Mediterranean from: a) faecal pellet density 1,29 g cm**3 (or pg µm**3) from Komar et al. (1981); b) faecal pellet DW/WW=0,23 from Elder and Fowler (1977) and c) faecal pellet C%DW=25,5 Marty et al. (1994).

Iron and manganese in bottom sediments and interstitial waters sampled in the White Sea on August 21-30, 2003

Iron and manganese in bottom sediments studied along the sublatitudinal transect from Kandalaksha to Arkhangelsk are characterized by various contents and speciations depending on sedimentation environment, grain size of sediments, and diagenetic processes. The latter include redistribution of reactive forms leading to enrichment in Fe and Mn of surface sediments, formation of films, incrustations, and ferromanganese nodules. Variations in total Fe content (2-8%) are accompanied by changes in concentration of its reactive forms (acid extraction) and concentration of dissolved Fe in interstitial waters (1-14 µM). Variations in Mn content in bottom sediments (0.03-3.7%) and interstitial waters (up to 500 µM) correspond to high diagenetic mobility of this element. Changes in oxidation degree of chemical elements result in redox stratification of sediment strata with maximum concentrations of Fe, Mn, and sulfides. Organic matter of bottom sediments with considerable terrestrial constituent is oxidized by bottom water oxygen mainly at the sediment surface or in anaerobic conditions within the sediment strata. The role of inorganic components in organic matter oxidation changes from surface layer bottom sediments (where manganese oxyhydroxide dominates among oxidants) to deeper layers (where sulfate of interstitial water serves as the main oxidant). Differences in river runoff and hydrodynamics are responsible for geochemical asymmetry of the transect. The deep Kandalaksha Bay serves as a sediment trap for manganese (Mn content in sediments varies within 0.5-0.7%), whereas the sedimentary environment in the Dvina Bay promotes its removal from bottom sediments (Mn 0.05%).
