Ontology-Based Modelling of Ocean Satellite Images

In this paper we will define an ontology about the semantic content of ocean satellite images in which we are able to represent types of

ocean structures

,

spatial

and

morphological

concepts, and knowledge about

measures

of temperature, chrolophyll concentration, among others. Such ontology will provide the basis of a classification system based on the low-level features of images. We have tested our approach using the

Protegé

semantic web tool.

A Survey on Ontology Metrics

Ontologies have been widely used in almost any field of application. The use of ontologies should involve the possibility of evaluation of the quality and correctness of them. Some tools and metrics have been proposed to reach this goal. ONTOMETRIC, OntoQA and Protégé represent the most important tools to evaluate ontologies. On the other hand, diverse cohesion, coupling and ranking metrics have also been proposed, as well as methodologies such as OntoClean. This paper analyses these tools and metrics, compare them and finally reviews the current state-of-the-art concerning to ontology metrics.

The Impact of Team Project on Students’ Learning: An Analysis of a Global IT Management Course

The research paper is analyzing the contribution of the team project (project based learning) as a group assignment in Global IT Management course offered at the master level in international programs at Royal Institute of Technology (KTH) Stockholm and Stockholm University towards the enhancement of students’ learning. The research methodology is a qualitative one and has been conducted through formal structured interviews with a group of students who have been acting as group leaders in Global IT Management course. Based upon the results coming from interviewing 7 out of 15 group leaders plus two additional interviews with students that were not group leaders we have found that the team project is enhancing their knowledge, is an assessment method better than a classic written exam and the students’ perception about the impact of the team project upon their learning is positive. Moreover the analysis of the data collected from these interviews has also provided usefully information about if the team project objectives are relevant in contributing to the enhancement of students learning, and what it can be done further for increasing students’ motivation in their team project work.

Towards an Ontology for the Description of Learning Resources on Disaster Risk Reduction

One of the priority areas of the Hyogo Framework for Action 2005-2015 for disaster risk reduction is the use of knowledge, innovation and education to build a culture of safety and resilience at all levels. The collection, compilation and dissemination of relevant information and knowledge on disaster risks and to cope with such risks are critical to inform and educate individuals as a basis on which to establish a culture of disaster prevention and resilience. However, in many cases these resources are scattered over multiple repositories in different places and lack a common, shared framework for their description to improve the search and retrieval process. This research intends to contribute to the Hyogo Framework of Action by building a domain ontology on disaster risk reduction for education. The goal is to provide semantically enriched descriptions of learning resources for the use in training curricula and learning programs. The ontology builds on the terminology of disaster risk reduction, published by the United Nations International Strategy for Disaster Reduction (UN/ISDR) in 2009. It extends the terminology by reusing other relevant ontology sources and incorporating the knowledge of subject matter experts.

Designing an Instrument to Measure the QoS of a Spanish Virtual Store

This article describes the development of an instrument, in the form of a survey, which is distributed to users of a B2C website selling electronic books in order to ascertain their satisfaction. The opinions compiled from a pilot sample and the exploratory factor analysis carried out point to factors that best summarise the quality of the application analysed here. Analysis of the initial survey, with a total of 40 items, shaped the final instrument, encompassing 18 items divided into 6 dimensions, which measure the perceptions of users of the application in order to improve the contents of the website. Subsequently, a confirmatory factorial analysis is performed, ensuring the reliability of the study and which confirms that the structure of the instrument developed truly measures service quality in accordance with the requirements of the website in terms of offering a space that fulfils consumer expectations in the Information Society.

Metadata and Ontologies in Learning Resources Design

Resource design and development requires knowledge about educational goals, instructional context and information about learner’s characteristics among other. An important information source about this knowledge are metadata. However, metadata by themselves do not foresee all necessary information related to resource design. Here we argue the need to use different data and knowledge models to improve understanding the complex processes related to e-learning resources and their management. This paper presents the use of semantic web technologies, as ontologies, supporting the search and selection of resources used in design. Classification is done, based on instructional criteria derived from a knowledge acquisition process, using information provided by IEEE-LOM metadata standard. The knowledge obtained is represented in an ontology using OWL and SWRL. In this work we give evidence of the implementation of a Learning Object Classifier based on ontology. We demonstrate that the use of ontologies can support the design activities in e-learning.

Open Integrated Personal Learning Environment: Towards a New Conception of the ICT-Based Learning Processes

Learning processes are changing related to technological and sociological evolution, taking this in to account, a new learning strategy must be considered. Specifically what is needed is to give an effective step towards the eLearning 2.0 environments consolidation. This must imply the fusion of the advantages of the traditional LMS (Learning Management System) – more formative program control and planning oriented – with the social learning and the flexibility of the web 2.0 educative applications.

For this goal, it is compulsory the evolution of the actual LMS to contexts where the new technological trends are integrated with them, introducing the social characteristics and putting the student in the centre of the educative process. These new systems are the Personal Learning Environments (PLE). Thus, we propose a learning personalization system construction that boosts student-centered educative actions. Two aspects are going to be considered, student learning personalization with information from the LMS and student learning personalization inside of an institution context.

An Assessment of Node Classification Accuracy in Social Networks Using Label-Dependent Feature Extraction

Node classification in Social Network is currently receiving raising attention in the Social Network Analysis research. The main objective of node classification is to assign the correct label to the unlabeled nodes from a set of all possible class labels. This classification task is performed using features extracted from a Social Network dataset. The success of proper feature extraction significantly influences classification accuracy, providing more discriminative description of the data. This paper describes label-dependent features extraction and examines the classification accuracy based on features extracted with this approach. The experiments on real-world data have shown that usage of label-dependent features can lead to significant improvement of classification accuracy.

Learning Assessment Using Wikis: Integrated or LMS Independent?

Wikis have a potentially huge educational value. This article outlines a feature set that wiki engines need in order to successfully host collaborative educational scenarios using wiki technology. One of the first issues to solve is the need for assessment methodologies supported by the software. And the second one is to choose between using an integrated wiki engine inside the Learning Management System (LMS), or an external standalone wiki engine. Advantages and disadvantages from both options of this second issue are discussed, with each choice presenting different implications as far as individual student assessment, feedback and grading are concerned. Among the expected results, the most notable are incentives to incorporate wikis in the teaching procedure, significant enhancements in usability, as well as allowing teachers to provide more timely written feedback on their students’ individual contributions on wiki based activities, on top of the usual numerical grading.

This paper exposes the conclusions of 5 years of experience of work in the field of wikis in education, development of improvements on open source wiki engines and thus, building from scratch accordingly the new wiki engine for the LMS Moodle 2.0.

Sustaining Tunisian SMEs’ Competitiveness in the Knowledge Society

The paper aims to contribute to the debate about knowledge and digital divide affecting countries’ competitiveness in the knowledge society. A survey based on qualitative and quantitative data collection has been performed to analyze the level of ICTs and e-Business adoption of the Tunisian SMEs. The results shows that to increase the SMEs competitiveness is necessary to invest in all the components of Intellectual capital:

human capital

(knowledge, skills, and the abilities of people for using the ICTs),

structural capital

(supportive infrastructure such as buildings, software, processes, patents, and trademarks, proprietary databases)

and social capital

(relations and collaboration inside and outside the company). At this purpose, the LINCET

“Laboratoire d’Innovation Numerique pour la Competitivité de l’Entreprise Tunisienne”

project is finally proposed as a coherent proposition to foster the growth of all the components of the Intellectual Capital for the benefits of competitiveness of Tunisian SMEs.

An Approach to Metadata Generation for Learning Objects

Metadata describe instructional resources and define their nature and use. Metadata are required to guarantee reusability and interchange of instructional resources into e-Learning systems. However, fulfilment of large metadata attributes is a hard and complex task for almost all LO developers. As a consequence many mistakes are made. This can cause the impoverishment of data quality in indexing, searching and recovering process. We propose a methodology to build Learning Objects from digital resources. The first phase includes automatic preprocessing of resources using techniques from information retrieval. Initial metadata obtained in this first phase are then used to search similar LO to propose missed metadata. The second phase considers assisted activities that merge computer advice with human decisions. Suggestions are based on metadata of similar Learning Object using fuzzy logic theory.

Web-Based Learning Information System for Web 3.0

With the emergence of Web/eLearning 3.0 we have been developing/adjusting AHKME in order to face this great challenge. One of our goals is to allow the instructional designer and teacher to access standardized resources and evaluate the possibility of integration and reuse in eLearning systems, not only content but also the learning strategy. We have also integrated some collaborative tools for the adaptation of resources, as well as the collection of feedback from users to provide feedback to the system. We also provide tools for the instructional designer to create/customize specifications/ontologies to give structure and meaning to resources, manual and automatic search with recommendation of resources and instructional design based on the context, as well as recommendation of adaptations in learning resources. We also consider the concept of mobility and mobile technology applied to eLearning, allowing access by teachers and students to learning resources, regardless of time and space.

Immersive Environments – A Connectivist Approach

We are conducting a research project with the aim of achieving better and more efficient ways to facilitate teaching and learning in Higher Level Education. We have chosen virtual environments, with particular emphasis to Second Life® platform augmented by web 2.0 tools, to develop the study. The Second Life® environment has some interesting characteristics that captured our attention, it is immersive; it is a real world simulator; it is a social network; it allows real time communication, cooperation, collaboration and interaction; it is a safe and controlled environment. We specifically chose tools from web 2.0 that enable sharing and collaborative way of learning. Through understanding the characteristics of this learning environment, we believe that immersive learning along with other virtual tools can be integrated in today’s pedagogical practices.

However, before we can apply and suggest best practices we need to get to know the virtual environments we intend to use (2D and 3D). We must characterize and understand how interactions and relationships are established, in particularly, between the users of this Multi-User Virtual Environment. We have made preliminary observations of residents’ behaviour at Second Life®, including some informal or natural learning contexts. Our analysis of those observations led strongly to theory of Connectivism approach, which is defined as a learning theory for the digital age.

This paper will present the outlined research and a literature review about the Connectivism theory and its application to the virtual environments.

ICT-Supported Education; Learning Styles for Individual Knowledge Building

School surveys and reports on integration of ICT in teaching and learning indicate that the technology is mainly used in traditional learning environments. Furthermore, the most frequently used software in the classrooms are general tools like word processors, presentation tools and Internet browsers. Recent attention among youngsters on social software / web 2.0, contemporary pedagogical approaches like social constructivism and long time experiences with system dynamics and simulations, seem to have a hard time being accepted by teachers and curriculum designers. How can teachers be trained to understand and apply these possibilities optimally that are now available in the classroom and online, on broadband connections and with high capacity computers? Some views on practices with the above-mentioned alternative approaches to learning are presented in this paper, focusing particularly on the options for online work and learning programmes. Here we have first hand experience with adult and mature academics, but also some background with other target groups.

Effective Design and Evaluation of Serious Games: The Case of the e-VITA Project

Learning and training are presently facing new challenges and a strong transformation. The use of electronic games for education (game-based learning) promotes an agile, immersive and stimulating form of learning that fosters learner engagement and motivation. Nonetheless, the design of effective and engaging educational games is a creative process that is unique to each situation. This paper discusses the inherent challenges of building intellectually appropriate and engaging games and presents the methodology adopted in the case of the e-VITA project that applies GBL to promote knowledge sharing and transfer for intergenerational learning. The paper analyses the e-VITAframework for SGs evaluation, which is central to the project’s iterative development approach. Early findings stemming from the validation of the e-VITA prototype game are also presented.

A Method for Group Extraction in Complex Social Networks

The extraction of social groups from social networks existing among employees in the company, its customers or users of various computer systems became one of the research areas of growing importance. Once we have discovered the groups, we can utilise them, in different kinds of recommender systems or in the analysis of the team structure and communication within a given population.

The shortcomings of the existing methods for community discovery and lack of their applicability in multi-layered social networks were the inspiration to create a new group extraction method in complex multi-layered social networks. The main idea that stands behind this new concept is to utilise the modified version of a measure called by authors multi-layered clustering coefficient.

Usability Evaluation of Web-Based Collaboration Support Systems: The Case of CoPe_it!

Usability is considered as a very significant factor towards the wide acceptance of software applications. Although the usability evaluation can take place in different forms, the entire evaluation procedure usually follows predefined ways according to a classification of the common characteristics of software applications. However, contemporary Web 2.0 applications, which aim at both social network development and collaboration support, reveal the need for modifying the settings of the evaluation procedure. This is due to some unique characteristics of these applications, such as the support of both synchronous and asynchronous collaboration, the use of common spaces for working and information exchanging, and the advanced notification and awareness services. This paper explores these applications’ particularities with respect to the way the whole usability evaluation procedure is affected and proposes a composite evaluation technique based on the development of appropriate heuristics that is suitable for such cases. The aforementioned issues are elaborated through the case of CoPe_it!, a Web 2.0 tool that facilitates and enhances argumentative collaboration.

User Interface Composition with COTS-UI and Trading Approaches: Application for Web-Based Environmental Information Systems

Due to the globalization of the information and knowledge society on the Internet, modern

Web-based Information Systems

(WIS) must be flexible and prepared to be easily accessible and manageable in real-time. In recent times it has received a special interest the globalization of information through a common vocabulary (i.e.,

ontologies

), and the standardized way in which information is retrieved on the Web (i.e., powerful search engines, and intelligent software agents). These same principles of globalization and standardization should also be valid for the user interfaces of the WIS, but they are built on traditional development paradigms. In this paper we present an approach to reduce the gap of globalization/standardization in the generation of WIS user interfaces by using a real-time “

bottom-up

” composition perspective with COTS-interface components (type interface

widgets

) and trading services.

A Module for Adaptive Course Configuration and Assessment in Moodle

Personalization and Adaptation are among the main challenges in the field of e-learning, where currently just few Learning Management Systems, mostly experimental ones, support such features. In this work we present an architecture that allows

moodle

to interact with the Lecomps system, an adaptive learning system developed earlier by our research group, that has been working in a stand-alone modality so far. In particular, the Lecomps responsibilities are circumscribed to the sole production of personalized learning objects sequences and to the management of the student model, leaving to

moodle

all the rest of the activities for course delivery. The

Lecomps

system supports the “dynamic” adaptation of learning objects sequences, basing on the student model, i.e., learner’s

Cognitive State

and

Learning Style

. Basically, this work integrates two main Lecomps tasks into

moodle

, to be directly managed by it: Authentication and Quizzes.

All in all, and so far, the advantage of the presented integration is in the real possibility to deliver and take personalized courses, residing and basically remaining into the

moodle

environment.

Using Learning Objects in Games

Our research in game based learning area is moving from traditional web-based Learning Management Systems towards game-based Learning Management Systems, with the intention of integrating upsides of using games in university education. This paper gives insight in to our recent work in area of reusability of Learning Objects between web-based LMSs and game-based LMSs. One of the major issues was how to use classical Learning Objects in development of educational games. We decided to apply a Model Driven Approach to Learning Objects repurposing, which represents a two-step process. Web based Learning Object is transformed into more abstract model and then returned enriched with game specific attributes to a platform specific model. For that purpose we propose a new term Educational Game Learning Object (EGLO). Different games that use different environment and settings can simply reuse Educational Game Learning Objects. Another contribution of our work is a software tool that can be used to import, transform, edit and add metadata, store and export Learning Objects. Applicability of this approach is demonstrated in one simple example.

Approaches to Learning and Kolb’s Learning Styles of Undergraduates with Better Grades

The purpose of this study is to investigate if the teaching, learning and assessment strategies conceived and implemented in a higher education chemistry course promote the development of conceptual understanding, as intended. Thus, our aim is to analyse the learning styles and the approaches to learning of chemistry undergraduates with better grades. The overall results show that the students with better grades possess the assimilator learning style, that is usually associated to the archetypal chemist. Moreover, the students with the highest grades revealed a conception of learning emphasising understanding. However, these students diverged both in their learning approaches and in their preferences for teaching strategies. The majority of students adopted a deep approach or a combination of a deep and a strategic approach, but half of them revealed their preference for teaching-centred strategies.

Semantically Enriched Tools for the Knowledge Society: Case of Project Management and Presentation

Working with semantically rich data is one of the stepping stones to the knowledge society. In recent years, gathering, processing, and using semantic data have made a big progress, particularly in the academic environment. However, the advantages of the semantic description remain commonly undiscovered by a “common user”, including people from academia and IT industry that could otherwise profit from capabilities of contemporary semantic systems in the areas of project management and/or technology-enhanced learning. Mostly, the root cause lays in complexity and non-transparency of the mainstream semantic applications. The semantic tool for project management and presentation consists mainly of a module for the semantic annotation of wiki pages integrated into the project management system

Trac

. It combines the dynamic, easy-of-use nature and applicability of a wiki for project management with the advantages of semantically rich and accurate approach. The system is released as open-source (OS) and is used for management of students’ and research projects at the research lab of the authors.

Application of Scientific Approaches for Evaluation of Quality of Learning Objects in eQNet Project

The paper is aimed to analyse the application of several scientific approaches, methods, and principles for evaluation of quality of learning objects for Mathematics subject. The authors analyse the following approaches to minimise subjectivity level in expert evaluation of the quality of learning objects, namely: (1) principles of multiple criteria decision analysis for identification of quality criteria, (2) technological quality criteria classification principle, (3) fuzzy group decision making theory to obtain evaluation measures, (4) normalisation requirement for criteria weights, and (5) scalarisation method for learning objects quality optimisation. Another aim of the paper is to outline the central role of social tagging to describe usage, attention, and other aspects of the context; as well as to help to exploit context data towards making learning object repositories more useful, and thus enhance the reuse. The applied approaches have been used practically for evaluation of learning objects and metadata tagging while implementing European eQNet and te@ch.us projects in Lithuanian comprehensive schools in 2010.

Survey on Intelligent Assistance for Workplace Learning in Software Engineering

Technology-enhanced learning (TEL) systems and intelligent assistance systems aim at supporting software engineers during learning and work. A questionnaire-based survey with 89 responses from industry was conducted to find out what kinds of services should be provided and how, as well as to determine which software engineering phases they should focus on. In this paper, we present the survey results regarding intelligent assistance for workplace learning in software engineering. We analyzed whether specific types of assistance depend on the organization’s size, the respondent’s role, and the experience level. The results show a demand for TEL that supports short-term problem solving and long-term competence development at the workplace.

V-NIP Ceaser: Video Stabilization System

In this paper, we propose a practical and robust approach of video stabilization that produces full-frame stabilized videos with good visual quality. While most previous methods end up with producing low resolution stabilized videos, our completion method produces full-frame videos by temporally filling in missing frame parts by locally aligning required data from neighboring frames. The proposed system has been evaluated on large number of real life videos; results were very promising and support the implementation of the solution.

Using Wikis to Learn Computer Programming

In this paper, we analyze the suitability of wikis in education, especially to learn computer programming, and present a wiki-based teaching innovation activity carried out in the first course of Telecommunication Engineering during two academic courses. The activity consisted in the creation of a wiki to collect errors made by students while they were coding programs in C language. The activity was framed in a collaborative learning strategy in which all the students had to collaborate and be responsible for the final result, but also in a competitive learning strategy, in which the groups had to compete to make original meaningful contributions to the wiki. The use of a wiki for learning computer programming was very satisfactory. A wiki allows to monitor continuously the work of the students, who become publishers and evaluators of contents rather than mere consumers of information, in an active learning approach.

Development of a Sensor Network System for Industrial Technology Education

Technology of e-learning has been gradually applied to all kinds of professional teaching fields. However, practicing and operation in real environment cannot be replaced by the method of e-learning such as multimedia and interactive simulations. The present e-learning system has very limited benefit for course of experiment and practical training, especially for the course which requires to experiment in clean room (ex. MEMS). Thus, the quality and quantity of industrial technology education cannot be improved. In order to overcome obstacles of traditional experiment and practical training course and enhance functions of present e-learning system, the study is going to take sensor network technology as foundation to developed web services system. The system is able to present the students ‘operation and results right away, thus students can be guided appropriately when they face problems during experiment and practical training. Besides, the system is able to record students’ learning process of experiment and practical training. These data of learning process will be helpful for building adaptive u-learning environment for skill-training.

Instructional Leadership and Schools Effectiveness

With the influx of information technology through the Internet and the use of ICT in our daily lives, our future generation has traversed from a mere change of era to a dynamic era of change. Thus, the role of school leaders is becoming more challenging than ever. They need to make greater strides to ensure that they are able to make adjustments and readjustments in instructional practices to cater for the changing elements in their organization. In brief, the school leaders have to be creative, innovative with entrepreneurial drive in order to steer their subordinates (teachers) towards school excellence. Leadership of principal is therefore considered as a main criterion to create successful schools in country’s educational advancement. Besides, the school effectiveness plays a crucial role in country’s academic advancement. This paper focuses on a comprehensive review of literature on the relationship between instructional leadership and school effectiveness.

Conversation Threads Hidden within Email Server Logs

Email server logs contain records of all email Exchange through this server. Often we would like to analyze those emails not separately but in conversation thread, especially when we need to analyze social network extracted from those email logs. Unfortunately each mail is in different record and those record are not tided to each other in any obvious way. In this paper method for discussion threads extraction was proposed together with experiments on two different data sets – Enron and WrUT..

Mobile System to Guide Blind People in a Well-Known Environment

The system aids to low-vision disabled people to move in a well-known environment, at the University of Almeria. So, a 3G mobile phone has been used in order to help blind people to have a better standard of life because they could go from a building to other using his mobile phone. Therefore, audible instructions are used to inform the user, which will have been decided in advance by the computer vision module (the decision will be taken according to the environment). That module captures images in real time (using the camera of the mobile phone, which has to be over the chest of the user, fixed with a string) and recognizes static objects in the middle of the way. Moreover, it tries to avoid the situation in which the user is going out of the way. On the other hand, an application has been developed so as to supervise all the users of the system and even visualize their position.

Indexing Moving Objects: A Real Time Approach

Indexing moving objects usually involves a great amount of updates, caused by objects reporting their current position. In order to keep the present and past positions of the objects in secondary memory, each update introduces an I/O and this process is sometimes creating a bottleneck. In this paper we deal with the problem of minimizing the number of I/Os in such a way that queries concerning the present and past positions of the objects can be answered efficiently. In particular we propose a new approach that achieves an asymptotically optimal number of I/Os for performing the necessary updates. The approach is based on the assumption that the primary memory suffices for storing the current positions of the objects.

A Criticism on the Bologna’s Learning Strategies

The stage of implementation of Bologna process will finish in Spain, and in particular at the University of Valladolid, into a few years. The new rules, in fact the ones related to new degrees, intend to provide more opportunities for european students in many senses: Knowing different universities, countries, and languages; new job opportunities coming out from the compatibility of the european degrees, and so on.

However some criticism deserve to be done, at least when involved in subjects so-called as

Basic Formation

as the one where the author of this paper works such a is Applied Mathematic field. In this paper we on the fact that not all new features of the Bologna process are expected to success, and that despite of several methodologies have been implemented and tried (even before Bologna process starts), the academic results are being not so good as expected.

Retracted: Application of Scientific Approaches for Evaluation of Quality of Learning Objects in eQNet Project

The paper is aimed to analyse the application of several scientific approaches, methods, and principles for evaluation of quality of learning objects for Mathematics subject. The authors analyse the following approaches to minimise subjectivity level in expert evaluation of the quality of learning objects, namely: (1) principles of multiple criteria decision analysis for identification of quality criteria, (2) technological quality criteria classification principle, (3) fuzzy group decision making theory to obtain evaluation measures, (4) normalisation requirement for criteria weights, and (5) scalarisation method for learning objects quality optimisation. Another aim of the paper is to outline the central role of social tagging to describe usage, attention, and other aspects of the context; as well as to help to exploit context data towards making learning object repositories more useful, and thus enhance the reuse. The applied approaches have been used practically for evaluation of learning objects and metadata tagging while implementing European eQNet and te@ch.us projects in Lithuanian comprehensive schools in 2010.

Exploring Learning through Audience Interaction in Virtual Reality Dome Theaters

Informal learning in public spaces like museums, science centers and planetariums is increasingly popular during the last years. Recent advancements in large-scale displays allowed contemporary technology-enhanced museums to get equipped with digital domes, some with real-time capabilities like Virtual Reality systems. By conducting extensive literature review we have come to the conclusion that little to no research has been carried out on the leaning outcomes that the combination of VR and audience interaction can provide in the immersive environments of dome theaters. Thus, we propose that audience collaboration in immersive virtual reality environments presents a promising approach to support effective learning in groups of school aged children.

Enhancing Collaborative Learning through Group Intelligence Software

Employers increasingly demand not only academic excellence from graduates but also excellent interpersonal skills and the ability to work collaboratively in teams. This paper discusses the role of Group Intelligence software in helping to develop these higher order skills in the context of an enquiry based learning (EBL) project. The software supports teams in generating ideas, categorizing, prioritizing, voting and multi-criteria decision making and automatically generates a report of each team session. Students worked in a Group Intelligence lab designed to support both face to face and computer-mediated communication and employers provided feedback at two key points in the year long team project. Evaluation of the effectiveness of Group Intelligence software in collaborative learning was based on five key concepts of creativity, participation, productivity, engagement and understanding.

‘The Lived Experience of Climate Change´: An Interdisciplinary and Competence-Based Masters Track Using Open Educational Resources and Virtual Mobility

Drawing on the authors’ involvement in a European Union Erasmus project, this paper explores a new holistic approach to climate change education which uses as a source of active/social learning and knowledge construction the diversity of different disciplinary and sectoral approaches. We further argue for a corresponding pedagogy based on developing transboundary competences where the communicative engagement across space and time, and between diverse perspectives and standpoints, is ICT-enabled. Meeting these challenges is a normative goal, not only for this expanded interdisciplinary approach to climate change education, but also for a global resolution of the climate change issue itself.

Student Performance in Online Project Management Courses: A Data Mining Approach

The paper presents the application of data mining for analyzing performance of students enrolled in an online two-year master degree programme in project management. The main data sources for the mining process are the survey made for gathering students’ opinions, the operational database with the students’ records and data regarding students activities recorded by the e-learning platform. More than 180 students have responded and more than 150 distinct characteristics/ variable per student were identified. Due the large number of variables data mining is a recommended approach to analysis data. Clustering, classification and association rules were employed in order to identify the factor explaining students’ performance. The results are very encouraging and suggest several future developments.

Effects of Digital Footprint on Career Management: Evidence from Social Media in Business Education

As online social media gain immense popularity among Internet users, we would like to explore the implication of social networking on career management. This paper links social capital theories and the impact of online social networks on ties between individuals in social and business uses. Social media contributes to building up individual digital footprint, or Internet content linked to individual names. We then propose a typology of the digital footprint based on the evidence from a survey of business students. Discussion of the implications of the study and arising research questions conclude the article.

Design of a Learning Environment for Management Education

The Case of EduORG2.0 at the University of Pisa

There has been a vast debate in recent years about usage patterns of social computing and web 2.0 tools in learning contexts. A growing number of researchers suggest that certain pedagogical approaches are best suited in these contexts, since they involve active engagement, social learning, continuous feedback, enabling students’ autonomous understanding and the transfer of those skills to useful or real-life settings. In this article we present the use of a social network as part of a formal course of Management at the University of Pisa. The institutional VLE – based on Moodle – has been integrated with a student support group hosted on Ning. Problems and opportunities for using Ning have been discussed in small groups and students feedback will be reported. The shift from Learning Management System (course centric) to a Personal Learning Environment (people centric) and then to Personal Learning Network is also been discussed and a framework for Education 2.0 is provided.

3D Visualization in Elementary Education Astronomy: Teaching Urban Second Graders about the Sun, Earth, and Moon

This research-in-progress hypothesizes that urban second graders can have an early understanding about the shape of Sun, Moon, and Earth, how day and night happens, and how Moon appears to change its shape by using three dimensional stereoscopic vision. The 3D stereoscopic vision system might be an effective way to teach subjects like astronomy that explains relationships among objects in space. Currently, Indiana state standards for science teaching do not suggest the teaching of these astronomical concepts explicitly before fourth grade. Yet, we expect our findings to indicate that students can learn these concepts earlier in their educational lives with the implementation of such technologies. We also project that these technologies could revolutionize when these concepts could be taught to children and expand the ways we think about children’s cognitive capacities in understanding scientific concepts.

Applying CIPP Model for Learning-Object Management

Although knowledge management process needs to receive some evaluation in order to determine their suitable functionality. There is not a clear definition about the stages where LOs need to be evaluated and the specific metrics to continuously promote their quality. This paper presents a proposal for LOs evaluation during their management for e-learning systems. To achieve this, we suggest specific steps for LOs design, implementation and evaluation into the four stages proposed by CIPP model (Context, Input, Process, Product).

An Empirical Study of IT Use in Pakistani Civil Society Organizations

As voulantary organizations are differnt from business and governmental organizations in terms of structure, working methodologies and decision making, we are interested in the specific IT requirements and technology use in this sector. In this paper we investigate the Pakistani civil society sector to analyze the involvement of technology in their work settings. The paper also discusses two successful virtual voulantary organizations to highlight the potential of new media. The findings suggest that lack of technological and financial resources hinder them to adopt innovative solutions. The technological use is mostly limited, but the realization of its importance and urge to establish ICT infrastructures exist. So there is need for appropriating technology so that this sector in collaboration with government institutions can serve the public in a better way in new knowledge society.

Towards Understanding IT Needs of Social Activists: The Case of the World Social Forum 2006 Organizing Process

Recent literature has highlighted that most civil society organizations lack IT appropriation in their work practices. There is strong need to focus on this application area to empower these organizations by IT capabilities. As there is not much literature about the specific needs assessment of voulantary organizations, there is a need to carry out ethnographic studies to better understand IT requirements of this sector. In this paper we have investigated the organizing process of the World Social Forum 2006 event in Karachi, Pakistan. World Social Forum is an important gathering of social movements and voulantary organizations across the globe, and organizing such an event requires extensive communication and effective planning skills. The objective of this paper is to highlight the need and importance of this research issue. Our intention is to introduce appropriate technology in the organizing process to facilitate social activists.

Assessing the Liquidity of Firms: Robust Neural Network Regression as an Alternative to the Current Ratio

Artificial neural networks have proven to be useful tools for solving financial analysis problems such as financial distress prediction and audit risk assessment. In this paper we focus on the performance of robust (least absolute deviation-based) neural networks on measuring liquidity of firms. The problem of learning the bivariate relationship between the components (namely, current liabilities and current assets) of the so-called current ratio is analyzed, and the predictive performance of several modelling paradigms (namely, linear and log-linear regressions, classical ratios and neural networks) is compared. An empirical analysis is conducted on a representative data base from the Spanish economy. Results indicate that classical ratio models are largely inadequate as a realistic description of the studied relationship, especially when used for predictive purposes. In a number of cases, especially when the analyzed firms are microenterprises, the linear specification is improved by considering the flexible non-linear structures provided by neural networks.

Knowledge Management through the Equilibrium Pattern Model for Learning

Contemporary students are characterized by having very applied learning styles and methods of acquiring knowledge. This behavior is consistent with the constructivist models where students are co-partners in the learning process. In the present work the authors developed a new model of learning based on the constructivist theory coupled with the cognitive development theory of Piaget. The model considers the level of learning based on several stages and the move from one stage to another requires learners’ challenge. At each time a new concept is introduced creates a disequilibrium that needs to be worked out to return back to its equilibrium stage. This process of “disequilibrium/equilibrium” has been analyzed and validated using a course in computer networking as part of Cisco Networking Academy Program at Effat College, a women college in Saudi Arabia. The model provides a theoretical foundation for teaching especially in a complex knowledge domain such as engineering and can be used in a knowledge economy.

A Web-Based Learning Information System Resource and Knowledge Management

AHKME e-learning system main aim is to provide a modular and extensible system with adaptive and knowledge management abilities for students and teachers. This system is based on the IMS specifications representing information through metadata, granting semantics to all contents in it, giving them meaning. Metadata is used to satisfy requirements like reusability, interoperability and multipurpose. The system provides authoring tools to define learning methods with adaptive characteristics, and tools to create courses allowing users with different roles, promoting several types of collaborative and group learning. It is also endowed with tools to retrieve, import and evaluate learning objects based on metadata, where students can use quality educational contents fitting their characteristics, and teachers have the possibility of using quality educational contents to structure courses. The metadata management and evaluation play an important role in order to get the best results in the teaching/learning process.
