A tool to simplify the management of homogeneous and heterogeneous grids

To simplify computer management, several system administrators are adopting advanced techniques to manage software configuration on grids, but the tight coupling between hardware and software makes every PC an individual managed entity, lowering the scalability and increasing the costs to manage hundreds or thousands of PCs. This paper discusses the feasibility of a distributed virtual machine environment, named Flexlab: a new approach for computer management that combines virtualization and distributed system architectures as the basis of a management system. Flexlab is able to extend the coverage of a computer management solution beyond client operating system limitations and also offers a convenient hardware abstraction, decoupling software and hardware, simplifying computer management. The results obtained in this work indicate that FlexLab is able to overcome the limitations imposed by the coupling between software and hardware, simplifying the management of homogeneous and heterogeneous grids. © 2009 IEEE.

Dermatúnel: Modelo de ambiente interativo de aprendizagem em dermatologia

The Interactive Learning Environment (ILE) is an educational model that integrates features of 3D computer graphics and contextualization, in order to transmit a quantum of knowledge (islands of knowledge), in a precise and agile way, to people who do not know the subject. It is a model that uses multimedia resources supported by a contextualized environment to motivate the participants in the retention of knowledge. In this first release, eight relevant subjects in dermatology were addressed and implemented in the 62nd Brazilian Congress of Dermatology. The model was called Dermatúnel. In a period of four days, 3295 people visited it. The results showed that the participants were highly satisfied. The model has a great potential as an educational tool for medical training and guidance to the general public with the purpose of disease prevention.

O ambiente educativo e o desenvolvimento do indivíduo portador do transtorno do déficit de atenção e hiperatividade (TDAH)

The pedagogical context can become a mediator between teaching and learning process. In a research conducted to obtain a Master’s degree, I could see how intentional organized environment refl ects in the knowledge appropriation and internalization historically produced. The objective of this study is to raise hypothesis about the favoring of the potentiating context of learning in the development of the individual with the Attention Defi cit Hyperactivity Disorder (ADHD) as well as on the organization of pedagogic environment to mediate the actions of teaching and reading learning. It is the concern to meet children with behavior considered inappropriate for the classroom environment and failure before situations that involve them. The hypothesis is that when the teaching and learning environment provides motivation to the student and awakens in him the desire to produce knowledge and take ownership of it, it is possible that it may have a potentiating development of learning. As theoretical support, I used texts from Luria (1987, 1994), Vygotsky (1994), Vigotskii, Luria and Leontiev (1998), Beaton (2005),Graeff and Vaz (2008), Pastura, Mattos and Araujo (2005). The bibliographic research was the methodology used for the study.

A perspectiva metodológica da resolução de problemas: um estudo sobre enunciados de situações matemáticas na EJA

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.

Avaliação da política curricular paulista: perspectiva docente sobre os cadernos do professor e do aluno

The current curriculum policy of the Secretary of Education in the State of Sao Paulo introduced into the education environment the Registrar of Teacher and Student - support material to ease the teacher's work and the student's learning, in order to address all the curriculum components created as strategy of learning. The resulting guidelines that aim to transform the everyday policies of educational institutions and the individuals who compose them, are incorporated into the school experience. These decisions, however, do not transfer into life outside the learning environment nor are they translated into the work of the teachers exactly as their creators intended. Thus, in order to better understand the curriculum policies introduced by the Registrar in schools, it is essential to comprehend the viewpoint of the teachers who themselves are both the targets and agents of curriculum policy, and later the Registrar. For that was made reflexive interviews with eigth teachers that teach in São Paulo metropolitan region, than we could see that they adapt their external determinations in their own reality

Reflexõs sobre a linguagem do ambiente chat no Teletandem sob a perspectiva da natureza heterogênea da escrita

This paper aims at discussing the characteristics of computer mediated language within a foreign language teaching and learning environment enabled by the use of synchronic writing resources – chat. The present research is based on (i) theoretical principles about the use of technologies and the teaching-learning of foreign languages in the scope of the Teletandem Brazil Project: Foreign languages for all – Projeto Teletandem Brasil: línguas estrangeiras para todos (TELLES, 2005); (ii) studies on the characteristics of the language within chat interactions; (iii) different theoretical perspectives on the relationship between spoken and written language, emphasizing the constitutive heterogeneity of writing perspective (CORRÊA, 1997, 1998, 2001); and (iv) some relevant concepts related to Prosodic Phonology field (NESPOR; VOGEL, 1986). Is being taken as research data, the written production of a Brazilian student (finishing a Licentiate in Literature) interacting with an American student (in Religious Studies) through Windows Live Messenger. The data were collected during a five-month period, during which the participants interacted through chat, totalizing 12 interactions in English and in Portuguese. During the analysis, a particular attention was given to the messages’ fragmentation, the use (or not) of punctuation signs and abbreviations within the Brazilian participant’s production, in order to discuss the representations she built of her writing, her interlocutor, herself and on the teaching-learning process of a foreign language.

Windows into Elementary Mathematics:Alternate public images of mathematics and mathematicians

Research on students’ (and teachers’) images of mathematics and mathematicians reveals a number of stereotypical images, most of which are negative. In this paper we present an overview of some these images and stereotypes and consider the questions: (1) how might the image of mathematics and mathematicians be a problem in mathematics education, and (2) what can be done to remedy the situation? Also, we consider an outreach project called Windows into Elementary Mathematics. In this project mathematicians are interviewed about their perspectives on elementary mathematics topics and their interviews are videotaped and are posted online, along with supporting images and interactive content. In this context we consider the questions: (3) what is the Windows project about, and (4) how might it offer an alternate (and perhaps better) image of mathematics and mathematicians? Lastly, we share an example where activities from the project were used in a math-for-teachers course.
