Scalable distributed virtual environments using multicast application level

Most of architectures proposed for developing Distributed Virtual Environment (DVE) allow limited number of users. To support the development of applications using the internet infrastructure, with hundred or, perhaps, thousands users logged simultaneously on DVE, several techniques for managing resources, such as bandwidth and capability of processing, must be implemented. The strategy presented in this paper combines methods to attain the scalability required, In special the multicast protocol at application level.

Digital proficiency and digital inclusion: Comparison between students of computer science, public relations and engineering

New information and communication technologies may be useful for providing more in-depth knowledge to students in many ways, whether through online multimedia educational material, or through online debates with colleagues, teachers and other area professionals in a synchronous or asynchronous manner. This paper focuses on participation in online discussion in e-learning courses for promoting learning. Although an important theoretical aspect, an analysis of literature reveals there are few studies evaluating the personal and social aspects of online course users in a quantitative manner. This paper aims to introduce a method for diagnosing inclusion and digital proficiency and other personal aspects of the student through a case study comparing Information System, Public Relations and Engineering students at a public university in Brazil. Statistical analysis and analysis of variances (ANOVA) were used as the methodology for data analysis in order to understand existing relations between the components of the proposed method. The survey methodology was also used, in its online format, as a research instrument. The method is based on using online questionnaires that diagnose digital proficiency and time management, level of extroversion and social skills of the students. According to the sample studied, there is no strong correlation between digital proficiency and individual characteristics tied to the use of time, level of extroversion and social skills of students. The differences in course grades for some components are partly due to subject 'Introduction to Economics' being offered to freshmen in Public Relations, whereas subject 'Economics in Engineering' is offered in the final semesters of Engineering and Information Systems courses. Therefore, the difference could be more tied to the respondent's age than to the course. Information Systems students were observed to be older, with access to computers and Internet at the workplace, compared to the other students who access the Internet more often from home. This paper presents a pilot study aimed at conducting a diagnosis that permits proposing actions for information and communication technology to contribute towards student education. Three levels of digital inclusion are described as a scale to measure whether information technology increases personal performance and professional knowledge and skills. This study may be useful for other readers interested in themes related to education in engineering. © 2013 IEEE.

GRAMMAR and COMMUNICATION IN PORTUGUESE AS A FOREIGN LANGUAGE A Study in the Context of Teletandem Interactions

This paper presents a study about the role of grammar in on-line interactions conducted in Portuguese and in English, between Brazilian and English-speaking interactants, with the aim of teaching Portuguese as a foreign language (PFL). The interactions occurred by means of chat and the MSN Messenger, and generated audio and video data for language analysis. Grammar is dealt with from two perspectives, an inductive and a deductive approach, so as to investigate the relevance of systematization of grammar rules in the process of learning PFL in teletandem interactions.

Concepções sobre Assimilação Solidária num curso universitário

O presente artigo é parte de uma tese de doutorado (Silva, 1997). A pesquisa foca as possibilidades, conseqüências e reflexões epistemológicas da implantação de uma proposta pedagógica alternativa ao ensino tradicional vigente (ETV) na disciplina Cálculo I, do Curso de Licenciatura em Matemática, Unesp, Câmpus de Bauru, durante o ano de 1995. Partindo do Contrato de Trabalho, segundo a Assimilação Solidária (cf. Baldino, 1995a), tematiza a articulação do funcionamento das regras do Contrato com a avaliação e o trabalho em grupo. Ao lado do prêmio ao saber, é considerado o justo prêmio ao trabalho coletivo produzido em sala de aula. A investigação, de ordem qualitativa, localiza-se na vertente Pesquisa-Ação (cf. Thiollent, 1992), na qual o professor-pesquisador tematiza sua própria sala de aula, além de contextualizar os sujeitos no seu meio sócio-histórico-político-cultural.

Avaliação: um contrato de trabalho

Este artigo apresenta, tendo em vista perplexidades constituídas a partir de uma leitura acerca do funcionamento do modelo tradicional de ensino, considerações sobre a Proposta Pedagógica Assimilação Solidária, AS (Baldino, 1995a). Proposta interventora, a AS muda o conceito de mérito, pois considera, ao lado do prêmio ao saber, o justo prêmio ao trabalho coletivo produzido em sala de aula. O instrumento fundamental da AS é um contrato de trabalho, negociado entre professor e alunos, que vincula a avaliação e o trabalho em grupos na sala de aula.

Catalogação, formas de representação e construções mentais

The cataloging process, is responsible for building systems consisting of sets of interconnected elements and combined forms of representation, creating tools to facilitate the flow of information in various informational environments. It presents structures that offer favorable conditions for access to formal codes of symbolic representation and to the channels of information transfer, performing with competence the decoding and encoding of codes and rules used to represent knowledge and to describe information, documents and resources. The objective of this paper is to present the challenge of transforming operational data into consistent information, the role of the forms of representation and the mental constructions for defining the memory markers of users of catalogs. It shows as results the memory markers indicated by three categories of users for the description of a book like resource and points to the need of collaborative and cooperative work in cataloging and to the need of catalog modelling focused on the user.

Inclusão de alunos com deficiência em escolas do campo: desafios da docência em contextos multisseriados

The challenges of dealing with diversity in the school, in a society that values standards, which homogenizes subjects, have been one of the main issues raised, both by researchers in the field of education as the segments that produce the policies in our country. The teatchers transformations, in the new needs prevailing in the era of postmodernity have inspired improvements in the teaching- -learning process and provide conditions to seek training professionals aware and critical in the process of being on social diversity. The present study aimed to investigate the challenges of teaching practice in the process of inclusion of students with disabilities in public schools in the Field of Concordia-SC. Such institutions have structures in their multigrade classes and organizations – with one teatcher for all. The methodological approach was qualitative in nature, with the instruments to collect data, semi-structured interviews and non-participant observation. We research subjects, two teachers of multigrade classes, Azucena and Dalia, which have enrollment of disabled students and the schools that comprise the Concordia Field. It was observed that as a result the main themes emerged from the interviews were: 1) Valuing and respecting the characteristics and capabilities of each student, 2) Design of classroom space as heterogeneous, rich in human diversity, 3) Cooperative work as a potentiator rhythms and different styles of learning, 4) continuing training of teachers: ensuring a “know-how”. It is hoped that the results of this study contribute to the formation and performance of the teacher in the process of inclusion of students with disabilities in school areas, especially in schools field.

A study on human error in the interaction with the computer systems

The term human factor is used by professionals of various fields meant for understanding the behavior of human beings at work. The human being, while developing a cooperative activity with a computer system, is subject to cause an undesirable situation in his/her task. This paper starts from the principle that human errors may be considered as a cause or factor contributing to a series of accidents and incidents in many diversified fields in which human beings interact with automated systems. We propose a simulator of performance in error with potentiality to assist the Human Computer Interaction (HCI) project manager in the construction of the critical systems. © 2011 Springer-Verlag.
