Although computer supported collaborative learning has been widely adopted in many educational institutions over the last decade, there exist still drawbacks which limit their potential in collaborative learning activities. Among these limitations, we investigate information security requirements in on-line assessment, (e-assessment), which can be developed in collaborative learning contexts. Despite information security enhancements have been developed in recent years, to the best of our knowledge, integrated and holistic security models have not been completely carried out yet. Even when security advanced methodologies and technologies are deployed in Learning Management Systems, too many types of vulnerabilities still remain opened and unsolved. Therefore, new models such as trustworthiness approaches can overcome these lacks and support e-assessment requirements for e-Learning. To this end, a trustworthiness model is designed in order to conduct the guidelines of a holistic security model for on-line collaborative learning through effective trustworthiness approaches. In addition, since users' trustworthiness analysis involves large amounts of ill-structured data, a parallel processing paradigm is proposed to build relevant information modeling trustworthiness levels for e-Learning.Peer ReviewedPostprint (author's final draft

In this context, e-Learning stakeholders, are increasingly demanding new requirements, among them, information security is considered as a critical factor involved in on-line collaborative processes. Information security determines the accurate development of learning activities, especially when a group of students carries out on-line assessment, which conducts to grades or certificates, in these cases, IS is an essential issue that has to be considered. To date, even most advances security technological solutions have drawbacks that impede the development of overall security e-Learning frameworks. For this reason, this paper suggests enhancing technological security models with functional approaches, namely, we propose a functional security model based on trustworthiness and collective intelligence. Both of these topics are closely related to on-line collaborative learning and on-line assessment models. Therefore, the main goal of this paper is to discover how security can be enhanced with trustworthiness in an on-line collaborative learning scenario through the study of the collective intelligence processes that occur on on-line assessment activities. To this end, a peer-to-peer public student's profile model, based on trustworthiness is proposed, and the main collective intelligence processes involved in the collaborative on-line assessments activities, are presented.Peer ReviewedPostprint (author's final draft

    The application of e-learning technology in teaching and learning environment in developing countries has created a significant impact especially to students and staff. Despite the fact that it attended a high level of acceptability, there are various security threats and implementation challenges militating against effective utilization of the e-learning platform. This paper, reviewed the impact associated with security vulnerabilities and implementation issues that impede successful e-learning implementation. Specifically, the review examined the effect of security challenges in e-learning and viability of e-learning implementation. This review found that there is need to develop a viable and holistic approach model that combines both biometric fingerprint and cryptography authentication techniques for the e-learning platform. It is recommended that there is need for adequate and uninterruptable bandwidth and power supply for e-learning sustainability.

Among collaborative e-Learning drawbacks which are not completely solved, we have investigated information security requirements in on-line assessment (e-assessment). To the best of our knowledge, security requirements cannot be reached with technology alone, therefore, new models such as trustworthiness approaches can complete technological solutions and support e-assessment requirements for e-Learning. Although trustworthiness models can be defined and included as a service in e-assessment security frameworks, there are multiple factors related to trustworthiness which cannot be managed without normalization. Among these factors we discuss trustworthiness multiple sources, different data source formats, measure techniques and other trustworthiness factors such as rules, evolution or context. Hence, in this paper, we justify why trustworthiness normalization is needed and a normalized trustworthiness model is proposed by reviewing existing normalization procedures for trustworthy values applied to e-assessments. Eventually, we examine the potential of our normalized trustworthiness model in a real online collaborative learning course.Peer ReviewedPostprint (author's final draft

    The Development Of Mutual Trust In British Workplaces Through ?Partnership?

    Get PDF
    This article examines the alleged links between 'partnership' forms ofmanaging workplace relationships in Britain, and the development ofintra-organisational 'trust'. The potential for mutually complementarylinkages between the two are clear, in theory at least: partnership,as defined here, should produce, nurture and enhance levels ofinterpersonal trust inside organisations, while in turn trust, asdefined here, legitimates and helps reinforce an organisation's'partnership'. Qualitative evidence drawn from the self-reports of keyparticipants in four partnership organisations provides considerablesupport for the claimed linkages, while also highlighting severalweaknesses, discrepancies and pitfalls inherent in the process ofpursuing trust through partnership. This research is of interest froma public policy perspective, most of all in the United Kingdom, wherepartnership is the favoured organisational model for the New Labourgovernment, most trade unions, and many employers (not to mention theEuropean Union) yet where an agreed definition of the idea has yet toemerge, and where still remarkably little is known about whatpartnership involves inside organisations. This analysis also seeks torestore the curiously neglected idea of trust to a position of centralimportance to the study of employment relations.United Kingdom;case studies;organisational change;trust;social partnership

    High School Student Reactions to an Interdisciplinary Teaching Method in Agricultural Education

    Full text link
    Tomorrow’s agricultural workforce will face challenges in the form of complex problems that transcend disciplinary boundaries, including food security. Addressing these complex issues requires professionals to work within and across disciplines in ways that may not have been required in previous generations. Teaching using an interdisciplinary approach may be one approach to helping students develop the skills needed to address these problems. The purpose of this study was to explore student reactions to being taught with an interdisciplinary teaching method in a secondary agricultural education context. Overall, students reacted favorably to this interdisciplinary teaching approach. Several student characteristics contributed to their reactions. Multiple aspects of the facilitation process also impacted student reactions, as did specific features of the interdisciplinary approach. The interdisciplinary teaching approach produced several learning outcomes beyond the technical concepts, including gaining new perspectives and critical thinking. Recommendations for teachers and recommendations for additional research are provided

    Performance measurement procedures that support innovativeness rather than hamper it

    Get PDF
    This paper addresses the contemporary challenges in increasing firm-level innovativeness and developing appropriate performance metrics. The authors discuss these challenges and provide a literature review on the innovation enhancing factors in service industries. They subsequently study the case of a multinational telecom company that tries to renew its innovative capabilities after a restructuring. An interpretative approach, based on employee focus group interviews and an extensive management workshop, is taken to co-develop context specific factors that enhance innovativeness. These factors include, amongst others, personal recognition and acknowledgement for an innovative achievement, available time, customer intimacy, and a clear innovation strategy. The identified factors will be used in a follow-up research aimed to develop performance measurement procedures that support the company to develop and exploit its innovative capabilities
