Acompanhar as interações sociais em Ambientes Colaborativos Virtuais de Aprendizagem (ACVAs) com uma quantidade cada vez maior de ferramentas colaborativas, que muitas vezes estende os limites do ACVA, oferecendo o suporte adequado e em tempo real aos aprendizes é um dos desafios mais intensos e exaustivos que os professores online enfrentam. O objetivo geral deste trabalho foi a investigação de como uma abordagem de monitoramento abrangente das interações sociais dos aprendizes no Amadeus-SIMM impactou positivamente na percepção e mediação docente de forma a promover uma melhoria da presença social online dos aprendizes.

O crescente número de afastamentos por doenças no trabalho é um assunto preocupante nas organizações. Pesquisas recentes demonstram que grande parte destes afastamentos estão relacionados com as Lesões por Esforço Repetitivo (LER) e os Distúrbios Osteomusculares Relacionados ao Trabalho (DORT), e que a realização de ginástica laboral (GL) em intervalos regulares durante o expediente do funcionário pode diminuir a incidência destas doenças. O objetivo deste trabalho é apresentar as contribuições da implantação de um software open source de GL para a promoção de um ambiente de trabalho mais saudável, visando a prevenção de LER/DORT. A metodologia aplicada é um estudo de caso de abordagem exploratória, com a participação voluntária de 23 funcionários de setores administrativos de um hospital público federal. O questionário nórdico foi aplicado antes da implantação do software de GL de modo a identificar sintomas musculoesqueléticos dos participantes do estudo, bem como foi aplicado um questionário para avaliar os possíveis benefícios após 6 meses do uso do software no ambiente corporativo. Como resultado, foi possível identificar a aceitabilidade do software pelos funcionários da pesquisa, além de dados de melhorias na qualidade de vida e no ambiente de trabalho.

Given the practical nature of the Brazilian Federal Institutes courses, the use of projects as a pedagogical tool is frequent. Projects have been considered one of the most suitable learning approaches to reach the 21st Century skills, such as Critical Thinking, Collaboration, Communication and Creativity. Project-based Learning is a student-centered learning methodology, and although it leads the course or part of it through a project, it differs from the simple use of that as part of the course evaluation. To ensure the effective promotion of these skills using projects, the Project-based learning (PBL) Gold Standard was designed to be essential requirements for an efficient project. This research seeks to ascertain how the application of classroom projects in the Federal Institutes are aligned to the recommendations of the methodology, it also examines whether these applications have been effective. From the report of the researched teachers (N = 170) from different areas and educational levels, it was possible to verify that at least 50% of teachers apply at least 4 of the minimum requirements for an efficient project (out of a total of 7). Although there is no full adherence to the methodology model, there is an efficient promotion of the 21st Century Skills.

Augmented Reality (RA) is gaining more popularity in several fields of application in the last decades. In this sense, this research aims to develop a systematic mapping review to reveal how this technology has been applied in the sports scenario. To achieve this goal, the researchers developed a systematic mapping protocol that returned 250 primary studies after applying the search String on the indexers Scopus and Web of Sciences. The Data Collect phase followed applying the exclusion criteria, reaching a consolidated inclusion of 171 studies to be analyzed and synthesized to answer the research questions. This review condensed the state-of-the-art of AR and sports areas, such as the areas and applications researched, tools/frameworks, input and output interaction styles most used, research gaps, and most common types of research.

Tracking interactions and activities on Virtual Learning Environments (VLEs) with an increasing number of collaborative tools, offering real-time support for students, is one of the most intense and exhaustive challenges online teachers face. Teachers must improve themselves, acquire different skills, and be available for a longer time to meet the needs of students. This research analyzed 131 Higher and Vocational teachers' Survey answers regarding their experiences about two main questions - the effort to follow up interactions and activities in Virtual Learning Environments' collaborative tools and their perception about Chatbots as a teacher assistant to performing routine and repetitive tasks.

Although there are many works on the Enterprise Architecture (EA) application in healthcare systems, the literature lacks studies that provide a systematic approach to this topic specifically. This work presents a deep and broad Systematic Literature Review (SLR) to select studies demonstrating current EA practices in healthcare systems. The researchers established an SLR protocol returning 280 primary studies after the first step of the Data Selection and a consolidated inclusion of 46 articles after the second step. It was assessed the level of disagreement during the team's evaluations using Cohen's Kappa. This SLR revealed essential aspects of state-of-the-art EA application in healthcare systems, such as the most used frameworks, methodologies, and specification tools, and the criteria for their choice.

Este artigo apresenta os resultados de uma ampla revisão sistemática da literatura (RSL) sobre a adoção da metodologia Aprendizagem baseada em Problemas (ABP) na Educação a Distância e Híbrida (EaDH). Foram analisados os estudos primários dos anos de 2008 a 2019 com o objetivo de refletir sobre como as principais etapas dessa metodologia estão sendo aplicadas na EaDH, quais os Ambientes Virtuais de Aprendizagem (AVA) e ferramentas mais utilizados, bem como os principais impactos da aplicação da metodologia ABP na EaDH. Um total de 633 estudos foram indexados a partir da string de busca, dos quais 77 foram analisados para responder às questões de pesquisa com base nos critérios de exclusão. Algumas conclusões foram que para 75% dos estudos analisados, as pesquisas e experiências de ABP apresentadas não estão vinculados a um AVA e que há na literatura poucas iniciativas de ferramentas integradas ou não aos AVAs que sejam específicas ao planejamento, execução ou avaliação de ABP.

The present work aimed to map the various requirements engineering techniques and methodologies for the construction of educational technologies through a systematic mapping study. The research protocol of this mapping included the planning, execution, and analysis of the results phases. This research added information about the diversity of methods and techniques of requirements engineering applied in the process of developing educational technologies. However, this research indicated that the phenomena related to the pedagogical practice experienced by teachers and students are sometimes relegated in this process. This work analyzed the primary studies of the last ten years, making it possible to identify gaps in this area of research to propose research and the generation of new forms of work in the development of educational systems.

To ensure transparency and provide ways for analysis and auditing of various public activities and expenditures, the Complementary Law 131, known as the "Transparency Law," requires the Union, States, and Cities to disclose their expenses in real-time through Internet. However, despite the apparent progress in opening data in Brazil, applications do not follow the various recommended models. Since this data is mostly unconnected, a clear view of the underlying contexts of a query becomes impossible. Thus, there is no clear relationship between recorded expenditure data for education, quality indicators, and/or descriptive census data. The following research sought to create relations between data from the Brazilian Federal Government Open Data Portal and the primary education quality indicator, IDEB, in the cities of the state. The methodology used was Data Mining, a research field resulting from the intersection between the areas of Computer Science and statistics, which seeks to discover non-trivial information hidden in large data. Using Correlation and Linear Regression in the collected and formatted data, it was not found linear relationship, indicating that only cities funding data is not sufficient to obtain a causal relationship with the IDEB average for municipalities. The statistical result found, although it does not provide a direct correlation between the variables investigated, represents a relevant scientific finding in the non-causal relationship itself. The more relevant contribution of this research is the process of selection, preprocessing, and transformation of the data scattered in different information sources and different formats of the analyzed data, as well as the originality of the analyzed causality.

A clear question related to the growing gap between the educational model still in force in Brazil, as being passive, content-based and teacher-centered, against the expectations of students of Z and alpha generation, as well as the demands of XXI century labor market, which requires innovation, creativity, collaboration, critical thinking, leadership, maximization of social and cultural interactions, has led to high rates of demotivation and consequent school dropout of students. The intense experience of three months in Finland, as a result of the participation in the Teachers for the Future 26/2015 SETEC / MEC / CNPq program, provided the author with a vast and transforming learning reach, as well as the possibility of observing in practice how the areas of collaborative and blended learning as well as educational technologies, besides being possible to be applied, could be improved and expanded. Returning to Brazil, more specifically to the IFPB classrooms, aroused the interest in disseminating this knowledge and experiences to IFPB teachers and managers, using different strategies described in this article. The actions that have been coordinated in the IFPB are included in the teaching, research and extension triad. In teaching, the experience in Finland has provided a significant change in how the learning process is conducted in the courses that the author is responsible for, as well as the possibility of offering training to teachers, managers and students on active learning methodologies, collaborative and social tools and formative and diagnostic evaluation. In the research, there are two ongoing projects, one of which is the development of the PrBL Tool for planning, execution and evaluation of Project-Based Learning, and the second that seeks to analyze the use of projects by IFPB teachers from the perspective of 21st Century competences and the Project-Based Learning premises. In the scope of extension, a project is underway for the construction and strengthening of a Collaborative Network of 21st Century Educators, composed of teachers and managers of federal institutions and NGOs. All the ongoing actions are results of IFPB’s calls and have shown significant results so far. The funding raised in the calls for proposals will promote scientific exchange through the presentation of papers at international conferences, as well as in the implementation of partnerships between Brazil and Finland researchers and practitioners for the dissemination of the educational experiences and findings.

Given the difficulty of identifying students at dropout risk from the native logs and reports of the Virtual Learning Environments (VLEs), computational methods and tools based on Learning Analytics (LA) have been researched and developed. The primary objective of this work was to develop a plugin-type tool that presents students at dropout risk using cognitive, social and behavioral indicators of students through filters, notifications and interactive graphs generated from Moodle VLE data.

It is apparent that regulators, sponsors, athletes and sports organizations have become more and more concerned about doping control. Despite the investments made in the past few years, recent studies show that Brazil´s sports confederations have not systematized the doping control process nor have they yet dealt satisfactorily with problems to do with transparency with regard to disclosing the results of tests. This study puts forward an Information System to support the Confederations in reviewing and implementing anti-doping measures and procedures. It is also hoped that the proposed integrated database of doping tests can help managers to draw up a public policy for this area.

rlr@ded.ufrpe.br, fcopetroniomedeiros@gmail.com, asg@cin.ufpe.br Abstract. Extracting relevant information in collaborative supported computer learning to enable an effective monitoring of students and fostering learning management is a challenge. Several works have been developed from data mining techniques for the purpose of educational decision making. The main objective of this study was to investigate the feasibility of using the linear regression model to obtain inferences in the early stages of conducting online courses as a way to support decision making by teachers and administrators. We propose the use of linear regression to estimate the performance of students based on their interactions within the learning management system, taking into account behavioral variables. The results showed that it's possible to use the linear regression technique to obtain inferences with good accuracy rates. Resumo. Extrair informacoes relevantes que auxiliem a gestao da aprendizagem e viabilizem o acompanhamento efetivo de estudantes em cursos mediados por tecnologia e um desafio. Diversos trabalhos vem sendo desenvolvidos a partir de tecnicas de mineracao de dados educacionais para fins de tomada de decisao. O objetivo principal deste trabalho foi investigar a viabilidade da utilizacao do modelo de regressao linear para a obtencao de inferencias em etapas iniciais da realizacao de cursos online, como forma de apoiar a tomada de decisao por parte de professores e gestores. Propomos a utilizacao da tecnica de regressao linear para estimar o desempenho de alunos baseados em suas interacoes dentro da plataforma virtual de aprendizagem, levando em consideracao variaveis comportamentais. Os resultados obtidos demonstraram que e possivel utilizar a tecnica de regressao linear para obter inferencias com boas taxas de precisao. 1. Introducao Interacao e um conceito complexo e multifacetado em todas as formas de educacao. Diversas taxonomias foram propostas ao longo das ultimas decadas. Moore (1989) descreveu tres formas de interacao em educacao a distância: interacao entre o professor e o estudante, interacao entre os estudantes e interacao entre o estudante e o conteudo. Anderson e Garrison (1998) expandiram a taxonomia proposta por Moore acrescentando tres novas formas de interacao: interacao entre os professores, interacao entre o professor e o conteudo e interacao entre os conteudos.

Due to the difficulty on teachers manually monitoring social interactions on the Collaborative Learning Environments (CLE), is expected some automatic support. The main objective of this work was to investigate and develop the architecture for monitoring social interactions called Amadeus-SIMA integrated with CLE Amadeus. This work validated two hypotheses through an empirical experiment: enhance the teachers' awareness of the student's social presence and predict the students performance based on social behaviors generated by Amadeus-SIMA.

Este trabalho propõe um modelo de monitoria virtual apoiado pela Plataforma de aprendizagem Amadeus e instancia este modelo como experimento inicial numa disciplina de um curso superior de tecnologia. Resultados preliminares foram satisfatórios e demonstraram a constatação das hipóteses levantadas.
