ABSTRACT We describe our use of the Experience API in preparing blue-collar workers for three frequently arising work contexts, including, for example, the requirement to perform maintenance tasks exactly as specified, consistently, quickly, and without error. We provide some theoretical underpinning for modi-fying and updating the API to remain useful in near-future training scenarios, such as having a shorter time allowed for kinaesthetic learning experiences than in traditional apprenticeships or training. We propose ways to involve a wide range of stakeholders in appraising the API and ensuring that any enhancements to it, or add-ons, are useful, feasible and compatible with current TEL practices and tools, such as learning-design modelling languages.

ABSTRACT The trends in web development of educational applications and of Web 2.0 or social applications are converging. Platforms are designed to host a variety of software components (called widgets or plugins), which can be organised or combined (mashed-up) at user’s convenience. Such platforms can be exploited as both personalised learning environment (PLE) and as social network applications. This article argues that six qualitative dimensions can be defined to analyse the main features of these platforms: the screen dimension measures the visual integration, the data dimension measures the portability of data, the temporal dimension measures the rate of data synchronisation, the social dimension measures the networking of users, the activity dimension measures the structuring of users’ interactions with the environment, and the runtime dimension measures the flexibility in accessing the environment from different end points. As a proof of concept of the introduced dimensions, a few familiar Web 2.0 platforms are first measured along each dimension and then, using the results visualised as spider diagrams, compared with respect to their usefulness as PLEs.

ABSTRACT Tout enseignement est à distance. De nouveaux environnements informatisés peuvent évaluer automatiquement diverses productions d’apprenants et leur procurer divers renseignements sur ces dernières. En révélant d’autres distances que physiques (épistémiques et sociales), et en s’agrégeant au sein de plates-formes sociales, ces environnements offrent de nouvelles perspectives dans l’enseignement à distance et en présence. Cet article présente trois widgets évaluant des aspects divers des processus d’apprentissage et délivrant leurs évaluations sous la forme de distances (distance sémantique, cognitive individuelle ou sociale). Ces trois widgets peuvent s’interconnecter pour former un environnement personnel d’apprentissage, environnement qui a fait l’objet d’une première étude exploratoire d’usage, avec des étudiants d’informatique.

Augmented Reality is providing a whole new set of possibilities to improve proficiency and safety on the workplace and reduce costs during training, in particular in manufacturing and automotive industries. Among the applications developed to support workers on the shop floor, telementoring plays a leading role as a demonstrator of the capabilities of AR in industry. This paper explores the user experience of telementoring via GhostHands-the use of a virtual model of a men-tor's real hands, appearing in a workers full AR view of a work task. The mentor can see the workers view 'through their eyes' and can place their GhostHands into that view. Both worker and mentor appear to cope with this 'ghost assisted' experience very well, and recognise a sense of joint accomplishment from the cues that the hands embody in completing a task.

A change in perspective can be certified in the recent years to technology-enhanced learning research and development: More and more learning applications on the web are putting the learner centre stage, not the organisation. They empower learners with capabilities to customize and even construct their own personal learning environments (PLEs). These PLEs typically consist of distributed web-applications and services that support system-spanning collaborative and individual learning activities in formal as well as informal settings. These PLEs typically complement or interface with Learning Management Systems (LMS) with additional widgets, services, and data integrated from and with organization-external learning tools. Consequently, the aim of this workshop is not to discuss the concepts PLE vs. LMS, but to focus more generally on how learning experiences can be enriched using mash-ups of widgets and services with microformats and how technology can help to respond automatically ...

Approaching technology-enhanced learning from the perspective of a learner, we foster the idea of learning environment design, learner interactions, and tool interoperability. In this paper, we shortly summarize the motivation for our personal learning environment approach and describe the development of a domain-specific language for this purpose as well as its realization in practice. Consequently, we examine our learning environment design language according to its lexis and syntax, the semantics behind it, and pragmatical aspects within a first prototypic implementation. Finally, we discuss strengths, problematic aspects, and open issues of our approach.

This deliverable addresses the challenges of developing an integrative framework for appraising and optimising production tasks, associated business models and training, and available workspaces and workplaces. The integration leads to additional innovations, notably the concept of “flexible placification” of production, by which we mean the support for experimentation with different physical deployment schemes for various parts of the production process. The overarching aim is to be able to extend the integrative framework to provide WorkPlace as enhanced Service (WPaaS++), where the enhancements are concerned with the augmentation of the performance of work-users of a workplace. The main idea behind how we support the deployment of intentional schemes (= business models) is to separate consideration of Spaces and Places, in our case WorkSpaces and WorkPlaces. WorkSpaces express the intentions of the underlying business model, and WorkPlaces express the deployment (= physical local...

Abstract The field of technology-enhanced learning has been blessed with interdisciplinarity. At the same time, this heterogeneity is also its curse, as each of the participating scientific communities brings along its own research tradition, and established as well as innovative tools to support the research process.

Blogging has become mainstream, even in Higher Education. How to successfully build and sustain dispersed cross-institutional learning networks, however, still remains a conundrum. Validation trials evaluating learning technology and practice lack possibilities to investigate this at scale with hundreds of individuals over yearlong periods of time. With this contribution, we therefore propose a model for simulating a Higher Education blogosphere in order to circumvent this cost and resources problem. The model is informed by actual, ...

The common understanding of learning shifted over the last decades from the traditional behaviorist approach to paradigms like constructivism or discovery learning and, further, started to take into account aspects like heterogeneity of tools and information resources. We assume that prominent Internet phenomena like Google or Wikipedia nowadays influence our learning habits. Against this background, learning platform developers start to consider Web 2.0 features, i.e. by adding tagging functions, collaborative elements, Wiki and Blogging components, etc. [5]. Still, many developments restrict themselves to a style platform and even a simple installation, while learners continue working with the applications and websites they are used to, even if they are encouraged to use a certain eLearning system. Moreover, learning facilitators might also want to recommend certain applications for specific activities, which, in sum, lead to a “heterogeneous space of software, tools and services”. Full-featured heterogeneous eLearning systems are thus, hard to integrate in single solution frameworks. In order to integrate e.g. distinct open source initiatives, Web 2.0 applications as well as personalizable or customizable tools, platform developers try to provide functionalities allowing users to (re)assemble or merge external systemic entities into the own platform, as can be observed in the field of enterprise information systems. In this paper, we present a mashup approach which is based on the XoWiki component [8] and enables a user to add web-based applications to Wiki content and to use and arrange these tools in a comfortable way. In the following, the paper gives a short overview on the topic at hand, describes critical challenges regarding the development of application mashups and – based on that – derives special requirements for eLearning

This is a conference paper. Automated essay scoring with latent semantic analysis (LSA) has recently been subject to increasing interest. Although previous authors have achieved grade ranges similar to those awarded by humans, it is still not clear which and how parameters improve or decrease the effectiveness of LSA. This paper presents an analysis of the effects of these parameters, such as text pre-processing, weighting, singular value dimensionality and type of similarity measure, and benchmarks this effectiveness by comparing machine-assigned with human-assigned scores in a real-world case. We show that each of the identified factors significantly influences the quality of automated essay scoring and that the factors are not independent of each other.

Recent studies indicate that blogs are the breakthrough user application of this decade. Yet, the blogosphere in its current form is suffering from various problems. The fuzziness of the audience, disconnectedness, fragmentation, and lack of conversational coherence may have their roots not only in sociological factors but also in technological shortcomings of the current infrastructure. These problems hinder an effective deployment of blogs in collaborative learning activities. Within this contribution, an interface specification for user- ...

iCamp is an EC-funded research project in the area of Technology Enhanced Learning (TEL) that aims to support collaboration and social networking across systems, countries and disciplines in higher education. The concept of an iCamp Space will build on existing interfaces and integrate shared community features. Interoperability amongst different open source learning systems and tools is the key to successful sustainability of iCamp. The content for this collaboration within social communities is provided via distributed networked repositories including, for example, content brokerage platforms, online libraries, and learning object databases. The innovative pedagogical model of iCamp is based on social constructivist learning theories. iCamp creates an environment for a new way of social networking in higher education that puts more emphasis on self-organised, self-directed learning, social networking and cross-cultural collaboration.

Personal learning environments (PLEs) require new ways to motivate and scaffold learners. In particular, practice sharing is of importance for learnercentric approaches in the scope of (technology-enhanced) lifelong learning, as it is an enabler for community building and sustaining. In this paper we elaborate prerequisites for ‘good practice sharing’ and explain how we realized these aspects in our PLE solution named Mash-Up Personal Learning Environments (MUPPLE.org). Finally, we argue for the utility of our MUPPLE approach by highlighting two different strategies of good practice sharing and their benefits for learning and community building.

Abstract This paper shows how informal learning experiences can be integrated into institutional formal learning processes by using blog-based networked ePortfolios. First, we briefly introduce into the realm of learning in distributed environments like personal learning environments and elaborate on the role of ePortfolios. Second, we show how ePortfolios function as a means to support and evaluate informal learning.

In technology oriented research in general, and in Technology Enhanced Learning (TEL) in particular, the use of buzzwords can be quite confusing and create the impression that the field suffers from waves of fashionable topics without making any real progress.“Social Learning”,“Learning 2.0” and similar such terms are certainly fashionable, but we do believe that there is also real substance behind these terms. The following chapters illustrate some of this substance.

In modern educational environments for group learning it is often challenging for tutors to provide timely individual formative feedback to learners. Taking the case of undergraduate Medicine, we have found that formative feedback is generally provided to learners on an ad-hoc basis, usually at the group, rather than individual, level. Consequently, conceptual issues for individuals often remain undetected until summative assessment.

Abstract: Coding and analysing qualitative interviews is one of several core techniques used in marketing research. Qualitative methods offer valuable information hardly gained by standard quantitative methods since open-ended questions and interviews provide deeper insight into customer demands. The main disadvantages of qualitative methods are their inherent subjectivity and their high costs.

Abstract Useful in many applications, text mining techniques offer the possibility to analyze texts and discover their semantic meaning. Unfortunately, most of these methods only work on textual data, but they are equally useful when dealing with spoken conversations. In this contribution we show how an open source and freely available Automatic Speech Recognition engine can be used out-of-the-box as a preprocessing step for keyword spotting by first transcribing spoken conversations.

This paper addresses the recent discussions on business models for e-learning. Throughout this paper, we contribute to this discussion by presenting evidence for the sustainability of e-learning projects at universities by discussing three cases of revenue models in the context of Learn@ WU. The cases include an advertising, a sponsorship, and a content distribution model. The paper shows that there is a significant potential for revenue, but one revenue model is hardly enough to cover the cost.

Over the last century, many theoretical frameworks and technological solutions for personalized e-learning have emerged. The underlying models, however, are often based on the practice that domain experts develop an adaptation strategy to personalize content or parts of a learning platform, which leads to different problematic aspects decreasing the feasibility or utility of such approaches.

Abstract—Assessing social competence is a time consuming and complex endeavor, which has prompted several institutions to implement automated assessment systems. Although other attempts have been made, the majority of automated assessments are still based on multiple-choice formats. Within this contribution, the authors therefore present a new method of how to assess social competence using LSA. The contribution first reports on the research design, then presents the findings which are subsequently discussed in brief.

The idea of Personal Learning Environments (PLEs) seems to polarise the educational sphere into supporters and opponents. Both groups relate their enthusiasm or criticism to underlying competences motivated by or needed for building up, running, and maintaining a PLE. Within the following article, results of a qualitative study with multiple cases will be presented to shed light onto which competence and which of its building blocks are involved in running a (mash-up) PLE.

Abstract. One of the issues for the Personal Learning Environment is the integration of personal tools with institution-centric information and services such as timetable information, and the coordination of cohort-specific group activities. One potential solution is the use of widgets–small, single-function applications that can be used in different applications, including personal technologies. One of the challenges facing the use of widgets is the diversity of platforms, and the issues around security, privacy and control.

Abstract Automatic evaluation of verbal activities has always been hard. On the one hand, teachers want to stimulate student engagement and therefore often base grades on the number of participations. On the other hand, if quantity is more important than quality, students might participate, but add nothing new to the conversation. Providing feedback for spoken conversations is another challenge, one that is often solved by doing things manually.

Personalized adaptive learning requires (IST, 2004) development of semantic-based and context-aware systems to acquire, organise, personalise, share and use the knowledge embedded in web and multimedia content, and achievement of semantic interoperability between heterogeneous information resources and services. This includes the possibility of systems to connect to other systems in a flexible and easy way as well as to bridge the semantical differences.

This paper elaborates on the design of a computer-based service to support conceptual development. Our ambition is provide learners a way to compare their conceptual development against different reference models, so they recognize the limits of their expertise. These models are (semi) automatically generated from learning materials and learner text inputs using Latent Semantic Analysis, a technique that can identify the concepts and their relations between the concepts contained in input text materials.

Abstract The mashup era has emerged in response to the challenge of integrating existing services, data sources, and tools to generate new applications. Mashups are usually realized either through a seamless integration, in which only the resulting application is known by the end-users, or through integration of original applications, data sources, and tools, particularly in terms of widgets, into the same graphical space, in which participating applications and data sources are identifiable by the end-users.
Purpose-Mashups have been studied extensively in the literature; nevertheless, the large body of work in this area focuses on service/data level integration and leaves UI level integration, hence UI mashups, almost unexplored. The latter... more
Purpose-Mashups have been studied extensively in the literature; nevertheless, the large body of work in this area focuses on service/data level integration and leaves UI level integration, hence UI mashups, almost unexplored. The latter generates digital environments in which participating sources exist as individual entities; member applications and data sources share the same graphical space particularly in the form of widgets.

Personal Learning Environments have emerged as a complementary, even challenging, paradigm to Adaptive Learning Systems. We consider the mash-up era as an appropriate approach for a successful realization of digital personal learning environments. However, mash-ups are also accompanied by critical technical and usability challenges. In this paper, we try to identify some of these challenges and present our solution approach which results in Semantic Mash-up Personal and Pervasive Learning Environments (SMupple).

Personal Learning Environments have emerged as a complementary, even challenging, paradigm to Adaptive Learning Systems. One can argue that Pervasive Learning Environments aim at replacing the physical learning environment while Adaptive Learning Systems focus on replacing the instructor. We believe that amalgamation of these two approaches in a complementary manner, ie through setting an appropriate balance between learner and system control, is promising.

Within the STELLAR project, we provide the possibility to use living documents for the collaborative writing work on deliverables. Compared to'normal'deliverables,'living'deliverables come into existence much earlier than their delivery deadline and are expected to'live on'after their official delivery to the European Commission. They are expected to foster collaboration. Within this contribution we investigate, how these deliverables have been used over the first 16 months of the project.

Abstract—Latent semantic analysis (LSA) is an algorithm applied to approximate the meaning of texts, thereby exposing semantic structure to computation. LSA combines the classical vector-space model− well known in computational linguistics− with a singular value decomposition (SVD), a two-mode factor analysis. Thus, bag-of-words representations of texts can be mapped into a modified vector space that is assumed to reflect semantic structure.

Abstract The Web puts a huge number of learning resources within reach of anyone with Internet access. However, many valuable resources are difficult to find due to the lack of interoperability among learning repositories. In order to achieve interoperability, implementers require a common query framework. This paper discusses a set of methods referred to as Simple Query Interface (SQI) as a universal interoperability layer for educational networks.

In our emerging knowledge society, a firm understanding of the interplay between the management of knowledge and learning is of strategic importance in order to create and maintain effective learning processes in a large variety of non-traditional learning situations (Lytras, Naeve and Pouloudi [36]). For example, as described by Grace and Butler in [18], Zuboff [87] argues that learning, integration and communication become key to leveraging employee knowledge.

Abstract. This paper reports on the descriptive results of an experiment comparing automatically detected reflective and not-reflective texts against human judgements. Based on the theory of reflective writing assessment and their operationalisation five elements of reflection were defined. For each element of reflection a set of indicators was developed, which automatically annotate texts regarding reflection based on the parameterisation with authoritative texts.

In the recent decade a plethora of interactive software tools, be they open source or proprietary, have emerged and perished in the realm of technology‐enhanced learning (TEL). Concomitantly, there have also been surge and demise of contents, social networks, and activities associated with the use of these TEL tools. It is intriguing to understand what factors contribute to their rises and falls, and how.

This deliverable gives a snapshot on the iteratively developing prototypes. It focuses on the integration of the showcases ie on turning the existing technology into web-based, service-oriented applications, and structuring their software architecture along the concept elaborated in the previous infrastructure deliverable D2. 1. This involves mainly the re-use of existing technology (hence the name 'showcases'), although several of these task showcases already involve new developments.

In order to support interoperability of learning tools and reusability of resources, this paper introduces a framework for harvesting learning objects from web-based content. Therefore, commonly-known web technologies are examined with respect to their suitability for harvesting embedded meta-data. Then, a lightweight application profile and a microformat for learning objects are proposed based on well-known learning object metadata standards.

Abstract. Science 2.0 is a rather young concept and despite its short history already induced numerous controversial positions, oscillating between new technologies and new practices. Even though many TEL researchers already use Science 2.0 tools, although not always labeled as such, there is no commonly shared practice and tools in use. Within this paper, we investigate the concept of Science 2.0 and propose an embracing definition.

Abstract: European higher education has started to successfully implement technology enhanced learning strategies. The level of uptake varies however substantially between institutions and countries. Regarding the technical solutions, a similarly heterogeneous picture can be drawn. Whereas the variety of commercially licensed and open source systems currently in use responds to different needs of the users, this technical diversity faces the drawback of restricted data exchange possibilities across systems.

Abstract. Personal learning environments (PLEs) require new ways to motivate and scaffold learners. In particular, practice sharing is of importance for learnercentric approaches in the scope of (technology-enhanced) lifelong learning, as it is an enabler for community building and sustaining. In this paper we elaborate prerequisites for 'good practice sharing'and explain how we realized these aspects in our PLE solution named Mash-Up Personal Learning Environments (MUPPLE. org).

Abstract Large research networks naturally form complex communities with overlapping but not identical expertise. To map the distribution of professional competence in field of 'technology-enhanced learning', the lexical semantics expressed in research articles published in a representative, large-scale conference (ED-MEDIA) can be investi-gated and changes in the topics covered can be tracked over time. Within this contribution, the two years 2000 and 2008 are used to con-trast the change in meaning structure.

Recent studies indicate that blogs are the breakthrough user application of this decade. Yet, the blogosphere in its current form is suffering from various problems. The fuzziness of the audience, disconnectedness, fragmentation, and lack of conversational coherence may have their roots not only in sociological factors but also in technological shortcomings of the current infrastructure. These problems hinder an effective deployment of blogs in collaborative learning activities.

The end of labour-intensive manufacturing leaves us with organizations, which receive their added value from the knowledge and the creativity of their employees rather than from their muscle-power. Fewer people, thinking better, and supported by clever machines and computers add more value than gangs or lines of unthinking “human resources”. The result is not only a requirement for different people, but different organizations, organizations which recognize that they cannot do everything themselves.

In AIED research, providing feedback for learning entails measuring differences among learners; between learners and their desired characteristics (eg, knowledge, competences, motivation, self-regulation processes); or between learners and their looked-for resources (eg, web-links, articles, courses) has often been performed by computing and analysing 'distances' using several techniques like factorial analysis, instance-based learning, clustering, and so on.
