This article presents part of a larger study on the use of reference sources to perform bibliographical search by graduate students in Education. Data relating to the use of the scientific journals by these students are presented and discussed. Sixty Education graduate students, 28 Master degree and 32 Doctoral, answered an electronic questionnaire. The students indicated the types of articles usually read and the importance attributed to each one. For each of treated themes in the electronic questionnaire, data are initially presented and analyzed in the set of the 60 participants of the study and then compared between master and doctoral students. Were used the Chi-squared (?2) test, the Fisher exact test and the Spearman’s correlation coefficient. Research reports were more frequently pointed out but less valued in comparison to articles referring to critical review and theoretical essay. Methodological articles, appearing in fourth position according to reading frequency and importance attributed, are more valued by doctoral than master students. The students read these articles using different procedures. The possible reasons for the students valorizing the articles of critical review and theoretical essays are discussed. The present study intends to offer a contribution to understand the use of scientific information by students, describing some graduate students’ habits related to information seeking in scientific journals, and reading of the articles published.

This article aims to present dada from a research about the construction of social knowledge under the Piagetian perspective. Beliefs of children and adolescents about not to learn were investigated. 80 individuals aged 6 to 16 years participated of this study. They had to answer to three methodological tools: a drawing, the analysis of a history and the analysis of a film which involved situations of not learning. It will be presented here the main results of the drawing task. Among other results, data indicate that a significant part of the participants blame the students themselves for not learning, by factors such as indiscipline and lack of motivation. Results also show that Brazilian individuals are not in advanced levels of understanding of social reality, even at older ages.

In this paper we discuss the importance of a methodological perspective of solving problems as a sustaining process of teaching mathematics situated on the perspective of concept formation. Organizing a significant didactic situation for students imposes the need to study the interaction between them and the teacher and between them and their mathematical knowledge, learning environment in which the mere transmission of content gives way to contextualization, to historicizing and handling of topics from intuitive and everyday situations for the student. Thus, we understand mathematics as a fundamental language for the creation of theoretical thinking as a whole. We made use of documental analysis and classroom situations aiming at the use of instructional procedure related to the resolution of problems with the purpose of overcoming some representations about the process of teaching and learning mathematics which is strongly marked by imitative-repetitive algorithmic procedures. Considering mathematics as an investigation discipline, we point out renewal prospects for the curricula of this discipline, which are concrete in the movement of cultural action of the school itself as the cell generating discussion.

The study aimed to analyze coping strategies used by Young soccer athletes during the competition period. 172 male soccer athletes of 8 teams participating in Copa São Paulo de Futebol Júnior 2013, aged between 15 and 20 years old, most of high school education took part in the study. As instrument it was used the Brazilian version of the Ways of Coping Scale. Therefore, a contact was made with teams, where they had permission or not to apply and then day and time were scheduled to data collection, this was made in order to preserve the teams performance. Given that, most of the data were collected during the rest period of the teams, that is, when there was a long interval between one match and another. Data analysis was performed using descriptive statistics and frequency through the program Statistical Package for Social Sciences (SPSS) version 17.0 for Windows. The collected data suggests that most athletes use the coping strategy problem-focused, because it had the highest average, while emotion-focused coping strategy was the factor with lowest average. The results indicate that athletes have a higher emotional control and aiming to solving the stressful situation at the own problem

The mathematical problem solving is very important in the student's school career, leading him to develop his creativity and self-confidence. The way the teacher explains specific content may interfere in the student learning. Some researches show that the teacher trust and his problem solving rapport lead to a more satisfying job. This research focused on students of the course PARFOR at UNESP Bauru. This work was performed in order to investigate the affinity, trust and attitudes toward mathematical problem solving, the performance from who have positive and negative attitudes and the results that may be generated during class

Com os avanços alcançados pela economia brasileira, considerada pela ONU uma economia de Desenvolvimento Humano Elevado, e pelos planos econômicos para galgar maiores patamares de desenvolvimento do país, como o PAC e Planos de Metas (para 2012), é necessário investigar se o desenvolvimento está sendo “engolfado” por toda a população - se os Estados e regiões mais atrasado, Norte e Nordeste, nesses primeiros anos do século 21, possuem condições de alcançar os Estados mais desenvolvidos do “Cone Sul”, ou seja, a integração da economia do país

This research aims at examining the relationship between the performance of elementary school students Cycle I in problem solving and attitudes toward mathematics. For this, a research was conducted at a state school in the city of Bauru which was selected for convenience. Participants were randomly selected consisting of 75 students, of whom 21 were third years and 57 were of three classes of fifth year. The instruments used for data collection were: a informative questionnaire to characterize the students in age, grade, favorite subjects and the least liked, among others, an attitude scale, Likert type, to examine the attitudes toward mathematics; a interviews with 11 selected students according to scores on the attitudes and mathematical problems to be solved through the method of thinking aloud. The results showed that the major difficulties encountered by students in solving problems were: to understand the problems, formalizing the reasoning, recognize in the problem the algorithms needed for its resolution, make calculations with decimal numbers, do combinatorics, using the sum of equal portions instead of multiplying, self-confidence and autonomy in what he was doing, and others; participants with positive attitudes towards mathematics showed greater confidence to solve problems as well as a greater understanding on what was required by them, but were not detected significant relation between the attitudes and performance, since it was unfavorable

The friction phenomena is present in mechanical systems with two surfaces that are in contact, which can cause serious damage to structures. Your understanding in many dynamic problems became the target of research due to its nonlinear behavior. It is necessary to know and thoroughly study each existing friction model found in the literature and nonlinear methods to define what will be the most appropriate to the problem in question. One of the most famous friction model is the Coulomb Friction, which is considered in the studied problems in the French research center Laboratoire de Mécanique des Structures et des Systèmes Couplés (LMSSC), where this search began. Regarding the resolution methods, the Harmonic Balance Method is generally used. To expand the knowledge about the friction models and the nonlinear methods, a study was carried out to identify and study potential methodologies that can be applied in the existing research lines in LMSSC and then obtain better final results. The identified friction models are divided into static and dynamic. Static models can be Classical Models, Karnopp Model and Armstrong Model. The dynamic models are Dahl Model, Bliman and Sorine Model and LuGre Model. Concerning about nonlinear methods, we study the Temporal Methods and Approximate Methods. The friction models analyzed with the help of Matlab software are verified from studies in the literature demonstrating the effectiveness of the developed programming

The present investigation intended to understand how Didatic has been interpreted by teachers who work with this discipline in undergraduate courses. We assume that there are still many controversies and contradictions in consideration of the epistemological status of didactics, and that this knowledge object is on constant review by professionals. Initially we were seeking evidence in the plans of courses, however, this search has put us in a situation of confusion, of uncertainty and highlighted structural problems which, at first, prevented us from using pure and simple of the contents of the plans. We analyzed 76 lesson plans, allocated to institutions in different Brazilian states, different types of institutions and the diversity was so great that led us to characterize this study as exploratory and tell us the relevance of analyzing them in the perspective of "facets". To deepen the understanding we were interviewing teachers and two focus groups conducted with teachers of Teaching. Triangulating the analysis of plans, with the reflections from the interviews, the speeches and also in the focus group data, observation of teaching practice, we put some insights on issues, even though preliminary and will require further research.

The research aimed to assess, according to the constructional approach by Goldiamond, the reports of 20 mothers of children with behavior problems, (clinical group) and 20 mothers of children without these problems (non-clinical group), social skills and behavior problems of pre-school, investigate the situations and behaviors of mothers before the behavior of children and suggest hypotheses for functionally equivalent behaviors that were investigated. The instruments used were two scales, a questionnaire and a structured interview. The results indicated that children of non-clinical group presented with more frequency and diversity, social skills and with less frequency, of behavior problems compared to children of the clinical group.
