A telepresence learning environment for opera singing: distance lessons implementations over Internet2

The Opera eLearning project developed a solution for opera singing distance lessons at the graduate level, using high bandwidth to deliver a quality audio and video experience that has been evaluated by singing teachers, chorus and orchestra directors, singers and other professional musicians. Prior to finding a technological model that suits the user's requirements, several experiments have been conducted, testing and prototyping different technologies, until arriving at a telepresence, immersive sound model. This paper summarises the findings of this pilot stage, and its interest includes the management of innovation exercises across a multidisciplinary team, based on usability and a user-centred design. Some of the technology tested includes professional audio and video equipment, software for A/V signal capturing and transmission on uncompressed formats, A/D converters, and other auxiliary devices. The resultant model has later been successfully used in a formal case study, delivering 14 remote masterclasses.     

Exploring affiliation network models as a collaborative filtering mechanism in e-learning

The online interaction of learners and tutors in activities with concrete objectives provides a valuable source of data that can be analyzed for different purposes. One of these purposes is the use of the information extracted from that interaction to aid tutors and learners in decision making about either the configuration of further learning activities or the filtering of learning resources. This article explores the use of an affiliation network model for such kind of purposes. Concretely, the use of techniques such as blockmodeling – a technique used to derive meaningful patterns of relationships in the network – and the analysis of m-slices – a technique helpful to study cohesion in relationships – are explored as tools to decide on the configuration of topics and/or learner groups. In particular, the results of the case study show that such techniques can be used to (i) filter participants for rearranging groups; (ii) rearrange topics of interest; and (iii) dynamically change the structure of a course. The techniques presented can be considered a case of collaborative filtering based on social network structure.     

Assessment of collaborative learning experiences by graphical analysis of wiki contributions

The widespread adoption of computers and Internet in our life has reached the classrooms, where computer-supported collaborative learning (CSCL) based on wikis offers new ways of collaboration and encourages student participation. When the number of contributions from students increases, traditional assessment procedures of e-learning settings suffer from scalability problems. In a wiki-based learning experience, automatic tools are required to support the assessment of such huge amounts of data. In this work, we present StatMediaWiki, a tool that collects and aggregates information that helps to analyze a MediaWiki installation. It generates charts, tables and different statistics enabling easy analysis of wiki evolution. We have used StatMediaWiki in a Higher Education course and present the results obtained in this case study.     

The body donation program at the Federal University of Health Sciences of Porto Alegre: A successful experience in Brazil

The use of dissection to study human anatomy is the foundation for educational excellence among future health professionals, as it offers an ideal opportunity to learn the body's morphology in three dimensions while also providing students with a more humanistic education. The shortage of bodies for dissection, combined with the Brazilian population's lack of knowledge concerning the possibility of voluntarily donating their own bodies, led to the creation of the Body Donation Programs for Education and Research in Anatomy at the Federal University of Health Sciences of Porto Alegre (UFCSPA). The program is based on three pillars: Informing the general public about the program, donor registration, and donation itself. Since the creation of the donor program in 2008, there has been an increase in both the number of donations made during donor's lifetime and the number of bodies received by the university. There has also been a shift in relation to the origin of these bodies, as before the creation of the program most bodies were unclaimed cadavers, while today most of the bodies are sourced from voluntary donations. The initial results regarding the public's acceptance of the possibility of making body donations have been encouraging, as shown by the annual growth in donor registrations. Consequently, the quality and quantity of the material available for educational purposes have greatly improved. Anat Sci Educ. © 2013 American Association of Anatomists.     

Educating to Build Bridges

In March 2012, 30 faculty and 49 students from all over the world met in El Calafate, Argentina, during two intense weeks. It was the second Latin American School for Education, Cognitive, and Neural Sciences (LASchool), sponsored by the James S. McDonnell Foundation. The LA School seeks to critically examine research findings potentially relevant to the development, design, and implementation of effective educational practices, and to foster a new generation of researchers able to operate at the interface between education and science. Here we introduce a special issue which brings together theory, experiments, and educational interventions which emerged from ideas presented and discussed during the 2012 LASchool.     

Distribution of influence,communication, and relational mentoring in the US superintendency

We report on how fifty superintendents (chief executive officers of public school systems, each invited by a researcher to participate) from seven states in the US talked in eight focus groups of their perspectives on their influence as leaders, their efforts to communicate with stakeholders, and how they learn from these stakeholders. We maintain that our participants’ revelations suggest that three definitions must be expanded to fit their work. First, influence or authority must be seen not merely as vested in the superintendent; rather, these superintendents described their leadership in terms of working with and through others. Second, organizational communication for these superintendents is more than the district’s leader communicating his or her perceptions and wishes to others; it is more relational, in which a variety of actors communicate their perspectives to one another. Third, this type of inter‐professional leadership leads logically to relational mentoring, where learning does not pass merely from expert to novice; rather, superintendents described their roles in terms of various parties learning from and teaching one another. We discuss implications of these insights for practice, research, and preparation.     

Yoga for the prevention of depression,anxiety, and aggression and the promotion of socio-emotional competencies in school-aged children

Children and youth coming from disadvantaged socioeconomic backgrounds are at risk of developing behavioural problems. This study examined the efficacy of a Yoga programme implemented in a low-socioeconomic status school, for the prevention of depression, anxiety, and aggression. After-school workshops were delivered twice a week during 12 weeks to 125 students in 5th, 8th, and 9th grades, enrolled in a school in Bogotá, Colombia. Participants were randomly assigned to an intervention and to a control group. Children's anxiety, depression, aggression, and some socioemotional competencies (specifically empathy, anger management, and prosociality) were quantitatively assessed before and after the intervention, by means of self- and peer-reported questionnaires. Qualitative data were also collected to assess children's perceived benefits from the workshops. Results suggested a potential of the programme to reduce children's anxiety problems, in particular. Results are discussed in terms of recommended improvements to the programme and its future evaluation.
