We briefly analyse the enhancement of eportfolio processes defined by Zubizarreta (2009) with the introduction of mobile technology. We give some examples of appropriation of mobile device usage in eportfolio processes carried out by student teachers. These examples become the evidence of the enhancement possibilities of one of the portfolio processes defined by Zubizarreta (2009), that of documentation.
GGULIVRR: Touching Mobile and Contextual LearningeLearning Papers
The quest of today’s learning communities is to creatively uptake and embed the emerging technologies to maintain the pace of change, of learning content and platforms, while satisfying learners’ needs and coping with limited resources. As information is delivered abundantly and change is constant, education focuses on driving 21st century fluency.
Project GGULIVRR, Generic Game for Ubiquitous Learning in Interactive Virtual and Real Realities, initiates the study of ubiquitous learning, investigating mobile and contextual learning, challenging small devices with sophisticated computing and networking capacities, testing the pervasive internet and exploring intelligent tags.
The goal of project GGULIVRR is to present learning communities a framework enabling learners to practice and enhance 21st century skills while generating and playing mobile contextual games.
Project GGULIVRR entices learners to get in touch. To play the contextual game one needs to physically go to a ‘touchable’ location, where real objects are tagged with an intelligent tag. By touching a tag one gets in touch with the contextual content. Through playing and developing GGULIVRR games one meets other gamers and developers as the project format induces interdisciplinarity, inter-social and intercultural communication and collaboration empowering local people to unlock contextual content with a minimal technical threshold.

We describe the concept, process and outcomes of this collaboration including challenges of designing and developing mobile learning applications in virtual teams.
Standing at the Crossroads: Mobile Learning and Cloud Computing at Estonian S...eLearning Papers
This paper studies the impact of mobile learning implementation efforts in Estonian school system – a process that has created a lot of controversy during the recent years. Best practices in mobile learning are available from the entire world, forcing schools to keep up the push towards better connectivity and gadgetry. Even in the best cases where the schools are provided with the necessary tools, the process has met a lot of scepticism from teachers who are afraid to implement new methods. Teachers are often cornered with the ‘comply or leave’ attitude from educational authorities, resulting in a multi-sided battle between involved parties.
We have surveyed students, teachers, parents and management at five Estonian front-runner schools to sort out the situation. The results show different attitudes among students, school leaders and staff – while all of them mostly possess necessary tools and skills, teachers almost completely lack motivation to promote mobile learning. We propose some positive and negative scenarios – for example, we predict major problems if teacher training will not change, e-safety policies are inadequately developed or authorities will continue the tendency to put all the eggs into one basket (e.g. by relying solely on closed, corporate solutions for mobile learning platforms).
Reaching Out with OER: The New Role of Public-Facing Open ScholareLearning Papers
Open educational resources (OER) and, more recently, open educational practices (OEP) have been widely promoted as a means of increasing openness in higher education (HE). Thus far, such openness has been limited by OER provision typically being supplier-driven and contained within the boundaries of HE. Seeking to explore ways in which OEP might become more needs-led we conceptualised a new ‘public-facing open scholar’ role involving academics working with online communities to source and develop OER to meet their needs.
To explore the scope for this role we focused on the voluntary sector, which we felt might particularly benefit from such collaboration. We evaluated four representative communities for evidence of their being self-educating (thereby offering the potential for academics to contribute) and for any existing learning dimension. We found that all four communities were self-educating and each included learning infrastructure elements, for example provision for web chats with ‘experts’, together with evidence of receptiveness to academic collaboration. This indicated that there was scope for the role of public-facing open scholar. We therefore developed detailed guidelines for performing the role, which has the potential to be applied beyond the voluntary sector and to greatly extend the beneficial impact of existing OER, prompting institutions to release new OER in response to the needs of people outside HE.
This paper reports on the current challenges the professional sector faces when going mobile. The report discusses the role of mobile devices in the workforce and addresses challenges like compatibility, security and training. It also provides a comprehensive review of the mobile landscape, and reviews current best practices in mobile learning.
Managing Training Concepts in Multicultural Business EnvironmentseLearning Papers
Companies that need training and development services increasingly often operate in a context that consists of more than just one country, language and culture. While business operations are becoming international, companies expect their service providers being capable of catering them where needed. Succeeding in a very complex multinational customer-tailored training project takes more than a good concept. The concept must be flexible so that when language and cultural changes vary from country to country they do not endanger the content to be delivered. There can be several localised versions of the training concept under simultaneous delivery. Challenge is how to manage the concept.

Comparative evaluation of four multi label classification algorithms in class...csandit
The classification of learning objects (LOs) enables users to search for, access, and reuse them
as needed. It makes e-learning as effective and efficient as possible. In this article the multilabel
learning approach is represented for classifying and ranking multi-labelled LOs, whereas
each LO might be associated with multiple labels as opposed to a single-label approach. A
comprehensive overview of the common fundamental multi-label classification algorithms and
metrics will be discussed. In this article, a new multi-labelled LOs dataset will be created and
extracted from ARIADNE Learning Object Repository. We experimentally train four effective
multi-label classifiers on the created LOs dataset and then, assess their performance based on
the results of 16 evaluation metrics. The result of this article will answer the question of: what is
the best multi-label classification algorithm for classifying multi-labelled LOs?

Reading has always been a foundational element of one’s education. The ultimate goal of reading, however, is not limited to word recognition; the reader’s success lies in comprehension. Comprehending a text is undoubtedly a complex process and it is even more difficult for all learners to acquire self-regulating reading skills. A framework of how a web-based reading environment should be designed in order to meet students’ diverse needs and help them develop reading comprehension skills through processes that favor self regulated reading is outlined in this paper. The attempted synthesis is based on the main premises of Self-regulation Theory and the pedagogical approach of Universal Design for Learning, taking advantage of the new possibilities offered by digital texts and Web 2.0 applications.

Leveraging Trust to Support Online Learning Creativity – A Case StudyeLearning Papers
The insights shared through this article build on data collected in real life situations. The work described here attempts to understand how trust can be used as leverage to support online learning and creative collaboration. This report explores this understanding from the teacher perspective. It examines trust commitments in an international setting within which learners from different European countries collaborate and articulate their learning tasks and skills at a distance. This research endeavour aims to recognize both individual and group vulnerabilities as opportunities to strengthen their cooperation and collaboration. We believe that by understanding how to assess and monitor learners’ trust, teachers could use this information to intervene and provide positive support, thereby promoting and reinforcing learners’ autonomy and their motivation to creatively engage in their learning activities.
The results gathered so far enabled an initial understanding of what to look for when monitoring trust with the intention of understanding and influencing learners’ behaviours. They point to three main aspects to monitor on students: (1) their perception of each others’ intentions, in a given context, (2) their level of cooperation as expressed by changes in individual and group commitments towards a particular activity; and, (3) their attitudes towards the use of communication mediums for learning purposes (intentions of use, actual use and reactions to actual use).
Innovating Teaching and Learning Practices: Key Elements for Developing Crea...eLearning Papers
This paper looks at how to innovate teaching and learning practices at system level. It describes the vision for ‘Creative Classrooms’ and makes a consolidated proposal for their implementation, clarifying their holistic and systemic nature, their intended learning outcomes, and their pedagogical, technological, and organisational dimensions for innovation. ‘Creative Classrooms’ (CCR) are conceptualized as innovative learning environments that fully embed the potential of ICT to innovate learning and teaching practices in formal, non-formal and informal settings.
The proposed multi-dimensional concept for CCR consists of eight encompassing and interconnected key dimensions and a set of 28 reference parameters (‘building blocks’). At the heart of the CCR concept lie innovative pedagogical practices that emerge when teachers use ICT in their efforts to organize newer and improved forms of open-ended, collaborative, and meaningful learning activities, rather than simply to enhance traditional pedagogies, such as expository lessons and task-based learning.
A preliminary analysis of two existing cases of ICT-enabled innovation for learning is presented in order to show (i) how the proposed key dimensions and reference parameters are implemented in real-life settings to configure profoundly diverse types of CCR and (ii) to depict the systemic approach needed for the sustainable implementation and progressive up-scaling of Creative Classrooms across Europe.
Website – A Partnership between Parents, Students and SchoolseLearning Papers
The website developed by the 1.b class at the Augusta Šenoa elementary school is, first and foremost, a pioneering work stemming from cooperation among teachers and parents. The purpose of the website is to inform, activate, and involve parents, students and teachers who work in the classroom. Each activity is documented, giving insight into the everyday activities, and making the classroom visible and transparent to everyone. The project uses new technology (forum, gallery of student work, class mail), and enlists a partnership of parents, who made parts of the website.
Academic Staff Development in the Area of Technology Enhanced Learning in UK ...eLearning Papers
This paper reports on a study on staff development in the area of technology enhanced learning in UK Higher Education Institutions (HEIs) that took place in November, 2011. Data for this study were gathered via an online survey emailed to the Heads of e-Learning Forum (HeLF) which is a network comprised of one senior staff member per UK institution, leading the enhancement of learning and teaching through the use of technology. Prior to the survey, desk-based research on some universities’ publicly available websites gathered similar information about staff development in the area of technology enhanced learning. The online survey received 27 responses, approaching a quarter of all UK HEIs subscribed to the Heads of e-Learning forum list (118 is the total number). Both pre-1992 (16 in number) and post-1992 Universities (11 in number) were represented in the survey and findings indicate the way this sample of UK HEIs are approaching staff development in the area of TEL.
The Ageing Brain: Neuroplasticity and Lifelong LearningeLearning Papers
The role of adult education is becoming increasingly important in the framework of policies to promote lifelong learning. Adult participation in training activities, however, is still rather low, despite the incentives and initiatives aimed at allowing all citizens access
to education and training at all ages in their lives.
Participation tends to decrease concomitantly with increasing age: the major difficulty that elderly people have in learning is due to a deterioration of brain function, causing a progressive weakening of concentration, memory and mental flexibility. Today, advanced
researches in neuroscience show that brain ageing may be reversible: the brain
is plastic in all stages of life, and its maps can restructure themselves through learning experiences.
Checklist for a Didactically Sound Design of eLearning ContenteLearning Papers
The design of elearning content requires several areas of educational psychology to be
integrated. In order to enhance the design process, checklists can be used as a means of formative evaluation. We present a checklist for the design and formative evaluation of elearning modules.
It covers the content, segmenting, sequencing and navigation, adaptation to target audience,
design of text and graphics, learning tasks and feedback, and motivation. In the context of a project on designing elearning modules on renewable energies, this
checklist was successfully used for providing formative feedback to the developers.
The International Student and the Challenges of Lifelong LearningeLearning Papers
Although few people would oppose the view that lifelong learning is intended to be a positive experience, it should be borne in mind that an ageing student body might require the development of additional tools and skills for the online educator.
In this short paper we present two cases of challenges faced by international learners who brought with them into the learning environment some issues that were the product, not only of the age of the learner in question, but also of the geographical environment
in which they studied. The names of the learners have been changed.

In this paper we present some aspects of mentoring, particularly the ICT support of such process and
give examples.
The Virtuous Circle of Use, Attitude, Experience and Digital InclusioneLearning Papers
eAdoption refers to how people learn to become ICT users. “Digital inclusion” however is a more complex status, related to people’s participation in communities and in other dimensions of society, based on knowledge. It refers to areas such as social relationships,
work, culture, politics, and so on.
This paper looks at how to evaluate digital inclusion, using an analysis that considers not only individual factors but community and social ones as well, going beyond an
eadoption perspective that is limited to a focus on skill-level.

Open Educational Resources (OERs) not only comprise LOs,
course materials, content modules and collections; like-
wise, include tools for creating, delivering, using and im-
proving educational contents. The term OER was first used
at a UNESCO conference in 20021. Previously, Koper (2001)
had proposed a meta-language that allows to codify (see
Figure 1) the pedagogic values of learning objects as units-
of-study, associating each element of content with infor-
mation describing its instructional strategy. Chitwood &
Bunnow (2005) defined LOs with five characteristics: small
units of learning, typically ranging from 2 minutes to 15
minutes; self-contained, each learning object can be taken
independently; reusable, a single learning object may be
used in multiple contexts for multiple purposes; can be ag-
gregated, learning objects can be grouped into larger col- Figure 1: EA common view of

3.2 Methodology 1. Did you prepare your repository to be accessed with differ-
ent mobile devices?
This survey is aimed to collect information about the reposi-
tory’s accessibility via mobile devices, potential future apps and
functionalities from the repository owner’s point of view. Con-
tent owners received an email in which they were prompted to
answer six questions related to mobile usage. Guidelines and
examples of possible ways to fill in the requested information
were included. The collected files were analyzed obtaining the
following results.
