Effectiveness of gamification in the engagement of students

This research aims to evaluate the effectiveness of gamification platforms as a strategy for the engagement of students from the 8th year of elementary school in Brazil. We chose two badging platforms - ClassDojo and ClassBadges - to be evaluated based on 7 different criteria. The main objectives were to generate involvement among individual and particular situations, increasing the interest, engagement and efficiency while performing a specific task. We observed the behavior of 61 students from an elementary public school in Brazil as part of our field research. Data were collected using observation, semi-structured interviews and questionnaires. Quantitative data were statistically analyzed using a multivariate technique known as cluster analysis. The results allowed us to classify students in 4 distinct groups and showed that students who received more rewards from the teacher got significantly better average performances. Cluster analysis was used to classify student engagement.Students with low engagement can be stimulated to do this activities through gamification techniques.Engagement indicators were identified and may be useful for future research in the area.Teacher participations is absolutely necessary to create experiences that include game mechanics for students.The objectives to be achieved in the classroom should be adherent with the mechanics of games.

Redundant VoD Streaming Service in a Private Cloud: Availability Modeling and Sensitivity Analysis

For several years cloud computing has been generating considerable debate and interest within IT corporations. Since cloud computing environments provide storage and processing systems that are adaptable, efficient, and straightforward, thereby enabling rapid infrastructure modifications to be made according to constantly varying workloads, organizations of every size and type are migrating to web-based cloud supported solutions. Due to the advantages of the pay-per-use model and scalability factors, current video on demand (VoD) streaming services rely heavily on cloud infrastructures to offer a large variety of multimedia content. Recent well documented failure events in commercial VoD services have demonstrated the fundamental importance of maintaining high availability in cloud computing infrastructures, and hierarchical modeling has proved to be a useful tool for evaluating the availability of complex systems and services. This paper presents an availability model for a video streaming service deployed in a private cloud environment which includes redundancy mechanisms in the infrastructure. Differential sensitivity analysis was applied to identify and rank the critical components of the system with respect to service availability. The results demonstrate that such a modeling strategy combined with differential sensitivity analysis can be an attractive methodology for identifying which components should be supported with redundancy in order to consciously increase system dependability.

Effectiveness of practices with sensors in engaging in meaningful learning in higher education: Extending a framework of ubiquitous learning

This paper aims to specify strategies for learning scenarios that incorporate ubiquitous features to support pedagogical practice. Thus, the development aims to verify if the resources of technology with context awareness promote significant changes in teaching practice, and can impact positively or not the effectiveness of learning and engagement of learners. In this regard, a reference ubiquitous environment called Youubi was used to support learning activities based on context. It consists of a framework of services that are easily integrated from applications in API format. In order to achieve the objectives of this research, the proposed method consists of three (03) phases. The first phase was a systematic review of the ubiquitous learning environments in order to identify which architectural features and their learning processes are used in learning scenarios based on the context. In the second phase an installation designed with the Youubi ubiquitous environment proposed a learning scenarios and new pedagogical practice for teachers in higher education. The third stage will be the design of high fidelity of ubiquitous learning scenarios prototype. After that, the actions will consist in validating the ubiquitous learning scenarios. In this paper we present the results of the systematic literature review. From these outcomes, we will generate pedagogical strategies for ubiquitous learning scenarios. These may also be used as recommendations to improve of current ubiquitous learning environments as well as the design of the Youubi environments.

Interfaces colaborativas para atividades assíncronas em fórum de discussão

A educacao a distancia tem ganhado significativa atencao tanto na academia quanto nas iniciativas governamentais. Neste contexto, cresce tambem a preocupacao com a avaliacao da qualidade dos diversos aspectos destes cursos mediados pelas tecnologias da informacao e comunicacao. Apesar de muitos trabalhos discutirem diversos aspectos da avaliacao em Ead, a literatura carece de relatos de experiencia que, especialmente, abordem os cursos tecnicos a distancia que possuem especificidades relevantes. Assim, este trabalho relata uma experiencia onde se avalia e adapta uma das propostas existentes na literatura de avaliacao mediada por foruns, ao contexto dos cursos tecnicos a distancia, constituindo-se esta adaptacao e sua discussao as principais contribuicoes do mesmo.Em Educacao a Distância mediada por meio de Ambientes Virtuais de Aprendizagem, foruns de discussao sao um instrumento importante e amplamente utilizado na articulacao de debates e discussoes entre os atores envolvidos no processo de ensino e aprendizagem. Com a ampla utilizacao dos foruns muitas mensagens sao trocadas e isso, por vezes, excede a capacidade de monitoramento por parte dos professores e tutores. O presente trabalho apresenta a concepcao de um classificador de mensagens de foruns que classifica as mensagens em positivas ou negativas, a fim de identificar mensagens que necessitam de maior atencao. Este trabalho aplica conceitos de mineracao de textos, com o algoritmo SVM obtendo taxas de acerto satisfatorias.Este artigo apresenta o framework Contagious, cujo proposito e estabelecer diretrizes que norteiem a construcao de redes sociais online orientadas a Difusao de Inovacoes. Compreendo-se o fenomeno das redes sociais online como consequencia natural do carater social do ser humano, vislumbrou-se esse meio tecnologico de comunicacao e interacao social como potencial ferramenta para a extensao de praticas educativas, com vistas a formacao do carater integral do cidadao. Para isso, foi adotada a teoria de Difusao de Inovacoes, propria das ciencias sociais. As contribuicoes deste trabalho, portanto, compreendem duas vertentes: a) o mapeamento de principios de uma teoria social na forma de recursos computacionais e; b) um enfoque orientado a educacao sobre as redes sociais online.A proposta do trabalho consiste em desenvolver um sistema para ser usado no celular como ferramenta de auxilio para alfabetizacao, utilizando-se de imagens e sons como forma de facilitar o aprendizado. Como metodo de desenvolvimento utiliza-se o processo P@PSEduc (Processo Agil para Software Educativo) e a ferramenta JME (Java Micro Edition).O crescente uso e difusao de tecnologias Web, a ubiquidade de ferramentas educacionais vem proporcionado verdadeiras revolucoes nos ambientes de ensino. Atualmente, sabe-se que nao mais se deve tratar alunos de forma homogenea, como se assim os fossem. Em face disso, este artigo apresenta um sistema adaptativo de apoio a aprendizagem colaborativa, cujo tema e a construcao e representacao do conhecimento por meio de mapas mentais multimidia. Tal sistema, baseia-se na Teoria da Carga Cognitiva, cuja preocupacao primaria e a facilidade com a qual as informacoes sao processadas pelos individuos.

U-Learning: A Collaborative Experience in the Urban Context

Mobile and ubiquitous technologies provide new learning experiences anytime, anywhere. In this type of learning mode, there are mechanisms that combine real scenarios with ubiquitous technologies, favoring a greater and meaningful exchange between individuals and groups through collaboration. In this sense, this study introduces an experience in the urban context supported by an u-learning environment in professional education. We used a ubiquitous learning platform called Youubi to lead an experiment at a public vocational school in Brazil. The theory of meaningful learning was used to support the interpret knowledge construction phenomena presents in the ubiquitous learning situation. It was proposed learning situations that allowed the exchange of meanings, based on the teachers’ planning based on the urbanization theme of the cities. The method was based on a hybrid-qualitative and quantitative analysis of ubiquitous learning in urban context. The results indicated that the features of the U-learning environment promoted collaboration around the didactic content outside the classroom in a dynamic way, allowing collaboration and knowledge sharing among those involved, mainly strengthening existing meanings and the perception of problems in life related to the proposed content.

Towards the process of identifying the strategies of self-directed learners in ubiquitous environments

Understanding the learning strategies conceived by self-directed learners has become a major challenge to be found in contexts supported by sub-domains of learning. For this objective to be achieved it is necessary to understand the different approaches that dimension the phenomenon, to explore the technologies created for this purpose and to discuss the results and limitations obtained through the research. Therefore, this paper aims to present an ongoing doctoral research that investigates the current solutions recommended by the literature to make it possible to create a process of identification of strategies of self-directed learners in ubiquitous learning environments.
