Discourses on ICT and development.

Research on ICT and development (ICTD) involves assumptions on the nature of ICT innovation and on the way such innovation contributes to development. In this article I review the multidisciplinary literature on ICTD and identify two perspectives regarding the nature of the ICT innovation process in developing countries - as transfer and diffusion and as socially embedded action - and two perspectives on the development transformation towards which ICT is understood to contribute - progressive transformation and disruptive transformation. I then discuss the four discourses formed by combining the perspectives on the nature of IS innovation and on the development transformation. My review suggests that ICTD research, despite its remarkable theoretical capabilities to study technology innovation in relation to socio-economic context, remains weak in forming convincing arguments on IT-enabled socio-economic development.

Argumentation Mining in User-Generated Web Discourse

The goal of argumentation mining, an evolving research field in computational linguistics, is to design methods capable of analyzing people's argumentation. In this article, we go beyond the state of the art in several ways. (i) We deal with actual Web data and take up the challenges given by the variety of registers, multiple domains, and unrestricted noisy user-generated Web discourse. (ii) We bridge the gap between normative argumentation theories and argumentation phenomena encountered in actual data by adapting an argumentation model tested in an extensive annotation study. (iii) We create a new gold standard corpus (90k tokens in 340 documents) and experiment with several machine learning methods to identify argument components. We offer the data, source codes, and annotation guidelines to the community under free licenses. Our findings show that argumentation mining in user-generated Web discourse is a feasible but challenging task.Comment: Cite as: Habernal, I. & Gurevych, I. (2017).

An Open Future for Higher Education

As the world becomes more open, universities have the opportunity to embrace openness in how they carry out their operations, teaching, and research. Open educational resources can provide the catalyst for different forms of learning, linking formal and informal aspects and splitting up the functions of content, support, assessment, and accreditation. Models from research suggest that an open approach is likely to encourage the crossing of boundaries between inside and outside the classroom, games and tools for learning, and the amateur and the expert. A new attitude toward research and scholarship is needed to work with the data of openness and to use it as an approach to gather evidence, share thoughts, and disseminate results

Kaleidoscope JEIRP on Learning Patterns for the Design and Deployment of Mathematical Games: Final Report

Project deliverable (D40.05.01-F)Over the last few years have witnessed a growing recognition of the educational potential of computer games. However, it is generally agreed that the process of designing and deploying TEL resources generally and games for mathematical learning specifically is a difficult task. The Kaleidoscope project, "Learning patterns for the design and deployment of mathematical games", aims to investigate this problem. We work from the premise that designing and deploying games for mathematical learning requires the assimilation and integration of deep knowledge from diverse domains of expertise including mathematics, games development, software engineering, learning and teaching. We promote the use of a design patterns approach to address this problem. This deliverable reports on the project by presenting both a connected account of the prior deliverables and also a detailed description of the methodology involved in producing those deliverables. In terms of conducting the future work which this report envisages, the setting out of our methodology is seen by us as very significant. The central deliverable includes reference to a large set of learning patterns for use by educators, researchers, practitioners, designers and software developers when designing and deploying TEL-based mathematical games. Our pattern language is suggested as an enabling tool for good practice, by facilitating pattern-specific communication and knowledge sharing between participants. We provide a set of trails as a "way-in" to using the learning pattern language. We report in this methodology how the project has enabled the synergistic collaboration of what started out as two distinct strands: design and deployment, even to the extent that it is now difficult to identify those strands within the processes and deliverables of the project.

Assessing Moral Judgements in Veterinary Students: An Exploratory Mixed-Methods Study from Germany

Although veterinary ethics is required in veterinary curricula and part of the competencies expected of a trained veterinary surgeon according to the European Association of Establishments for Veterinary Education (EAEVE), knowledge concerning the effects of ethics teaching and tools evaluating moral judgement are scarce. To address this lack of tools with a mixed-methods approach, a questionnaire with three case scenarios presenting typical ethical conflicts of veterinary practice was administered to two groups of veterinary students (one had taken ethics classes, one did not). The questionnaire contained both open-ended and closed questions and was analysed qualitatively and quantitatively. The qualitative part aimed at revealing different argumentation patterns between the two groups, whereas the quantitative part focused on the students’ approval of different roles and attitudes possibly relating to veterinarians. The results showed no major differences between both groups. However, answering patterns suggest a clear diversity among the students in their perception of morally relevant factors and the veterinary profession. Awareness of morally challenging elements of their profession was presented by students of both groups. With this exploratory study, the application of an innovative mixed-methods tool for evaluating the moral judgement of veterinary medical students is demonstrated

Case-Based Collaborative Learning in Undergraduate Radiology Teaching-Are Essential Conditions for Group Discussions Met?

BACKGROUND: Delivering case-based collaborative learning (cCBL) at scale using technology that both presents the clinical problem authentically and seeks to foster quality group discussion is a challenge, especially argumentation which is critical for effective learning. The aim of this study was to investigate the presence of essential conditions to capitalize on a technology-enhanced cCBL scenario for teaching radiology and facilitating quality group discussion. METHODS: A questionnaire was administered to 114 fourth-year medical students who completed a technology-enhanced cCBL scenario for teaching neuroradiology. It consisted of individual online pre-class work and face-to-face in-class work, where group discussion followed individual work at a workstation. Items from the "Heedful Interrelating in Collaborative Educational Settings" scale and "positive emotional engagement" questionnaire assessed the quality of social-cognitive processes and emotional engagement during the group discussions. Structured interviews were used to explore the teachers' awareness of and engagement with the technology. RESULTS: The mean scores of most "heedfulness" items were below 3.5 (7-point scale), suggesting that participants did not enter the debriefing with a mindset conducive for argumentation. However, for the affective states "interest" and "enjoyment" the mean scores were above 5. Free text comments suggested participants enjoyed the superficial interactions, but did not necessarily engage in argumentation. Structured interviews revealed teachers were aware of the possibilities of the learning dashboard and used it as a common frame of reference, but did not really succeed to use it as a springboard for discussion. CONCLUSION: A technology-enhanced cCBL scenario is useful for teaching radiology in undergraduate medical education, but the added value of acquiring in-depth knowledge will only be achieved when students are aware of the importance of an "heedful" mind-set
