A model for providing emotion awareness and feedback using fuzzy logic in online learning
Monitoring usersâ emotive states and using that information for providing feedback and scaffolding is crucial. In the learning context, emotions can be used to increase studentsâ attention as well as to improve memory and reasoning. In this context, tutors should be prepared to create affective learning situations and encourage collaborative knowledge construction as well as identify those studentsâ feelings which hinder learning process. In this paper, we propose a novel approach to label affective behavior in educational discourse based on fuzzy logic, which enables a human or virtual tutor to capture studentsâ emotions, make students aware of their own emotions, assess these emotions and provide appropriate affective feedback. To that end, we propose a fuzzy classifier that provides a priori qualitative assessment and fuzzy qualifiers bound to the amounts such as few, regular and many assigned by an affective dictionary to every word. The advantage of the statistical approach is to reduce the classical pollution problem of training and analyzing the scenario using the same dataset. Our approach has been tested in a real online learning environment and proved to have a very positive influence on studentsâ learning performance.Peer ReviewedPostprint (author's final draft
Rethinking university assessment
Developments in globalisation and new technologies are making significant impacts in higher education. Universities in a global market are increasingly concerned to reorient their degree programmes to meet the vocational needs of the Knowledge Economy. A growing adoption of technology enhanced learning, through blended and networked learning, has the potential to transform higher education practice â but assessment methods have been slow to change. This paper argues the case for universities to align assessment methods to meet the needs of 21st Century knowledge workers. It identifies skills and dispositions associated with graduate occupations in the Knowledge Economy, informing a new conceptual model for assessment. Radical recommendations are made to faculty staff and university policymakers: instead of centring assessment on the personal, academic achievements of individuals at the end of a degree course, the focus should instead be on the quality of the collective, applied achievements of students operating in project teams
Using Augmented Reality as a Medium to Assist Teaching in Higher Education
In this paper we describe the use of a high-level augmented reality
(AR) interface for the construction of collaborative educational applications
that can be used in practice to enhance current teaching
methods. A combination of multimedia information including spatial
three-dimensional models, images, textual information, video,
animations and sound, can be superimposed in a student-friendly
manner into the learning environment. In several case studies different
learning scenarios have been carefully designed based on
human-computer interaction principles so that meaningful virtual
information is presented in an interactive and compelling way. Collaboration
between the participants is achieved through use of a
tangible AR interface that uses marker cards as well as an immersive
AR environment which is based on software user interfaces
(UIs) and hardware devices. The interactive AR interface has been
piloted in the classroom at two UK universities in departments of
Informatics and Information Science
Assessing collaborative learning: big data, analytics and university futures
Traditionally, assessment in higher education has focused on the performance of individual students. This focus has been a practical as well as an epistemic one: methods of assessment are constrained by the technology of the day, and in the past they required the completion by individuals under controlled conditions, of set-piece academic exercises. Recent advances in learning analytics, drawing upon vast sets of digitally-stored student activity data, open new practical and epistemic possibilities for assessment and carry the potential to transform higher education. It is becoming practicable to assess the individual and collective performance of team members working on complex projects that closely simulate the professional contexts that graduates will encounter. In addition to academic knowledge this authentic assessment can include a diverse range of personal qualities and dispositions that are key to the computer-supported cooperative working of professionals in the knowledge economy. This paper explores the implications of such opportunities for the purpose and practices of assessment in higher education, as universities adapt their institutional missions to address 21st Century needs. The paper concludes with a strong recommendation for university leaders to deploy analytics to support and evaluate the collaborative learning of students working in realistic contexts
Analytic frameworks for assessing dialogic argumentation in online learning environments
Over the last decade, researchers have developed sophisticated online learning environments to support students engaging in argumentation. This review first considers the range of functionalities incorporated within these online environments. The review then presents five categories of analytic frameworks focusing on (1) formal argumentation structure, (2) normative quality, (3) nature and function of contributions within the dialog, (4) epistemic nature of reasoning, and (5) patterns and trajectories of participant interaction. Example analytic frameworks from each category are presented in detail rich enough to illustrate their nature and structure. This rich detail is intended to facilitate researchersâ identification of possible frameworks to draw upon in developing or adopting analytic methods for their own work. Each framework is applied to a shared segment of student dialog to facilitate this illustration and comparison process. Synthetic discussions of each category consider the frameworks in light of the underlying theoretical perspectives on argumentation, pedagogical goals, and online environmental structures. Ultimately the review underscores the diversity of perspectives represented in this research, the importance of clearly specifying theoretical and environmental commitments throughout the process of developing or adopting an analytic framework, and the role of analytic frameworks in the future development of online learning environments for argumentation

Due to pervasiveness of ICT's, most of collaboration can be performed through communication media channels such as discussion forums, social networks, etc. The emotive state of the users while they carry out their activity such as collaborative learning at Universities or project work at enterprises and organizations influences very much their performance and can actually determine the final learning or project outcome. Therefore, monitoring the users' emotive states and using that information for providing feedback and scaffolding is crucial. To this end, automated analysis over data collected from communication channels is a useful source. In this paper, we propose an approach to process such collected data in order to classify and assess emotional states of involved users and provide them feedback accordingly to their emotive states. In order to achieve this, a fuzzy approach is used to build the emotive classification system, which is fed with data from ANEW dictionary, whose words are bound to emotional weights and these, in turn, are used to map Fuzzy sets in our proposal. The proposed fuzzy-based system has been evaluated using real data from collaborative learning courses in an academic context.Peer ReviewedPostprint (author's final draft
Knowledge management : critical perspectives on e-business activities
This article is both a review and an agenda-setting piece. It argues that knowledge management suffers from conceptual and definitional ambiguity, oversimplification of its development processes, and methodological limitations. Nevertheless, there is a consensus in business and academia that knowledge is a key component of success and allows firms to achieve and sustains competitive advantages. In a digital era, these advantages arise from the potential of data and information that can be gathered, processed, shared, and used to improve e-business activities. Thus, this research bridges the gap in the assessment of knowledge management and e-business relationship, by applying an SEM to a large database sample of KM activities performed by European firms.N/

Exploiting tacit knowledge through knowledge management technologies
The purpose of this paper is to examine the contributions and suitability of the available knowledge management (KM) technologies, including the Web 2.0 for exploiting tacit knowledge. It proposes an integrated framework for extracting tacit knowledge in organisations, which includes Web 2.0 technologies, KM tools, organisational learning (OL) and Community of Practice (CoP). It reviews a comprehensive literature covering overview of KM theories, KM technologies and OL and identifies the current state of knowledge relating to tacit knowledge exploitation. The outcomes of the paper indicate that Internet and Web 2.0 technologies have stunning prospects for creating learning communities where tacit knowledge can be extracted from people. The author recommends that organisations should design procedures and embed them in their Web 2.0 collaborative platforms persuading employees to record their ideas and share them with other members. It is also recommended that no idea should be taken for granted in a learning community where tacit knowledge exploitation is pursued. It is envisaged that future research should adopt empirical approach involving Complex Adaptive Model for Tacit Knowledge Exploitation (CAMTaKE) and the Theory of Deferred Action in examining the effectiveness of KM technologies including Web 2.0 tools for tacit knowledge exploitation
