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.     

Learning in higher education – how cognitive and learning styles matter

The cognitive and learning styles research domain is a highly complex one which has recently been the focus of rigour–relevance debates (Coffield et al. 2004; Evans and Sadler-Smith 2006; Rayner 2006). There is considerable support for the existence and value of style as a construct (Sternberg 1996) even though further work is needed to evidence greater impact on practice. This paper shares the work and experiences of one international research community – the European Learning Styles Information Network (ELSIN) and its attempts to advance understanding of the theory and application of cognitive and learning styles in higher education and other contexts. In so doing it highlights the principles around the development, collation and integration of research as exemplified by the ELSIN experience and considered by other research domains in higher education. Future directions for cognitive and learning styles research within the context of higher education are outlined along with the role of ELSIN in highlighting and leading on these.     

The role of external experts’ intervention in higher education institutions for radical change

This paper focuses on the way lecturers observe, feel restrained by and cope with quality management systems that have been implemented in the higher education systems of the United Kingdom and the Netherlands. As two sides of the same coin, quality enhancement and quality control are of increased significance in European Higher Educaction Institutions (HEIs), particularly through the Bologna Process. We are interested in the way that both enhancement and control blend into the current systems, and we are concerned for too much dominance of control, as has been suggested in recent managerial literature. Analysis of 40 interviews in both countries among researchers and lecturers in traditional and universities of applied sciences showed many similarities. It is not so much the general idea of quality management that is being turned down by the respondents. They see the benefits quite clearly. Still, the general belief is that quality management in its current shape and character does not fit with the work of the individual academic, neither their teaching nor their research. The respondents worry for and resent the consequences of increased emphasis on quality assurance and control. The developments concerning the quality management of their HEIs are perceived in terms of quality assurance by the UK respondents. Instead, the Dutch are more occupied with finding ways to “how to deal with” such developments.     

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.     

Out in school: talking about sexual orientation and challenging homophobia across the Key Stage 4 curriculum

Rates of sexually transmitted infections and teenage pregnancy amongst the under-16s are causing increasing concern. There is limited evidence about the sexual behaviour and sex education preferences of this age group, especially of those from Black and minority ethnic groups. This study aimed to provide data on early heterosexual risk behaviour, and to examine preferences for the content and delivery of sex and relationships education (SRE), across ethnicity, gender and school year to inform priority setting and sex education strategies. A cross-sectional study of 3334 13–17-year-olds from 10 English urban and suburban secondary schools was conducted. Multivariate analysis was performed to examine the independent effect of demographic variables on sexual experience and preferences for sex education. A number of important differences in the sexual experience and condom use of males and females across the ethnic groups were identified. Differences in preferences for the content and delivery of sex education were also identified, particularly between male and female pupils. The findings indicate the potential for quite wide variation in sexual experience and preferences within school classrooms. The challenge for educators is therefore to develop SRE curricula that are inclusive within the constraints of school teaching.     

Bridging memory-based collaborative filtering and text retrieval

When speaking of information retrieval, we often mean text retrieval. But there exist many other forms of information retrieval applications. A typical example is collaborative filtering that suggests interesting items to a user by taking into account other users’ preferences or tastes. Due to the uniqueness of the problem, it has been modeled and studied differently in the past, mainly drawing from the preference prediction and machine learning view point. A few attempts have yet been made to bring back collaborative filtering to information (text) retrieval modeling and subsequently new interesting collaborative filtering techniques have been thus derived. In this paper, we show that from the algorithmic view point, there is an even closer relationship between collaborative filtering and text retrieval. Specifically, major collaborative filtering algorithms, such as the memory-based, essentially calculate the dot product between the user vector (as the query vector in text retrieval) and the item rating vector (as the document vector in text retrieval). Thus, if we properly structure user preference data and employ the target user’s ratings as query input, major text retrieval algorithms and systems can be directly used without any modification. In this regard, we propose a unified formulation under a common notational framework for memory-based collaborative filtering, and a technique to use any text retrieval weighting function with collaborative filtering preference data. Besides confirming the rationale of the framework, our preliminary experimental results have also demonstrated the effectiveness of the approach in using text retrieval models and systems to perform item ranking tasks in collaborative filtering.
