Team Composer: Assembling groups through social matching

Teams composition of is key factor to its success, but differences between individual and collective interests result in obstacles for the configuration of teams. Considering only individuals skills is not enough to assemble a working group. We present Team Composer, an application based on Genetic Algorithm that implements a social matching strategy that combines skills, socio-emotional factors and roles to support the composition of teamwork.

A cooperative approach for information recommendation and filtering

Teams are more efficient than groups of individuals, especially when the team adopts a cooperative approach. However, a high level of communication and an established culture are required in order to obtain the benefits of team work. An information system is described that attempts to increase the potential of the team by supporting group communication and interaction. The work focuses on the cooperative filtering of the information used by the group to support the performance of its tasks. The information system aims at reducing the difficulties of group work and increasing the information selection level. Some validation is carried out by means of a couple of experiments with small groups of people working as a team.

Modelo de Desenvolvimento de Objetos de Aprendiagem Baseado em Metodologias Ágeis e Scaffoldings

O desenvolvimento de objetos de aprendizagem exige modelos instrucionais e de desenvolvimento flexiveis, por se tratar de uma categoria de software com um conjunto de requisitos bastante especificos e demandas tecnologicas singulares. O uso de metodologias ageis para o desenvolvimento de objetos de aprendizagem pode facilitar esse processo permitindo a modelagem das funcionalidades baseados nos requisitos de comportamento do aluno. O presente artigo tem como objetivo discorrer sobre uma experiencia no de desenvolvimento de objetos de aprendizagem, baseado em metodologias ageis e interface baseada em scaffoldings.

Towards Reputation Systems applied to Communities of Practice

Communities of practice (CoPs) encourage the exchange of experiences within organizations, but there is a risk involved in regard to the quality of participation. For this reason, it is important to provide a means for the community to be able to recognize the reliability and usefulness of the participation of individuals involved. This paper presents a proposal for the use of reputation systems in CoPs in order to assist users in creating relationships for honest and useful participation, based on trust, for the benefit of the entire community.

Scoring Mechanisms to Encourage Participation in Communities of Practice

The process of creation of organization knowledge is a social process within which knowledge is shared among the members comprising an organization. Communities of practice have stood out as a way of promoting organizational learning, facilitating information and the knowledge exchange process among the members of an organization. Therefore, it is up to the companies to encourage their building and upkeep. This work presents the scoring strategy to encourage the participation of its members. A case study is presented, describing the application of the scoring mechanism to a community of practice, using work/learning cooperative/collaborative environment named TeamWorks

Designing support to participation in communities of practice through recommender systems

Communities of practice have been adopted by many organizations to promote collaborative learning and sharing of knowledge. Although various applications have been built to support this learning process, they fail to deal with one of the main problem: keeping users interacting and exchanging relevant information. We claim that the supporting system should provide the necessary stimulus for the community members to collaborate. Therefore, we claim the recommendations as a type of loyalty mechanism. The design of the collaborative environment TeamWorks is presented, illustrating our proposal.

Microgenetic Wire Conductor: a technique for metacognitive mediation in computer games

This study aims to present the Microgenetic Conductor Wire, a tool for metacognitive mediation in computational games. We present the preliminary results of application of this method taking two games provided with educational content belonging to the mathematical sciences and developed onto concrete material, in children between 9 and 10 years. The data generated showed cognitive improvements identified by the emergence of Innovative Schemes (Inhelder [ 6 ]) for the resolution of problems in games. We present evidence that learning is disconnected from predefined chronological stages as Piaget argued. Our results verified that content requiring complex mathematical reasoning and that are expected with over 12 years in the formal operations stage of abstract reasoning (Piaget [17]), can be learned and consolidated by younger children in the range between 9 and 10 years.

Promoting learning through social networks supported by a model of social combination

Resumo A busca por conhecimento aumenta cada vez mais na internet atraves das redes sociais. Encontrar os pares com diferentes niveis de conhecimento nao e uma tarefa trivial. Propoe-se o modelo Oraculous 1 baseado em estrategias de Sistemas de Combinacao Social, descrevendo funcionalidades a serem integradas em um ambiente computacional para o encontro de pares. Esse modelo usa anotacoes que um individuo faz sobre paginas da Internet para modelar a combinacao entre individuos, de modo a potencializar o aprendizado em rede atraves do encontro de pessoas com os mesmos interesses.

TeamWorks: supporting and stimulating participation in communities of practice

The communities of practice have been one of the ways adopted by organizations to promote the sharing of knowledge, the cooperative learning and consequently the improvement of working processes. However, one of its greatest problems is how to keep users interacting and exchanging relevant information to the whole community. Loyalty mechanisms used in marketing are proposed as a solution for this problem, aiming to stimulate the active participation of the members. A cooperative work environment, named TeamWorks is presented, illustrating the loyalty mechanism concerning documents recommendation.

Social Networks Applied to Zika and H1N1 Epidemics: A Systematic Review

Background: Health crises and health emergencies occur regionally and globally. In this context, online social networks are technical resources widely used to share large amounts of information with increasing reach and speed. This capacity of dissemination of information on epidemics through social media interactions creates the possibility of collaboration between population and health professionals or agencies. This article intends to present, through results obtained in a systematic review, examples on how social interactions enable collaboration in health surveillance to treat the epidemic situations of Zika and H1N1.
