Designing a mobile language learning system based on lightweight learning objects

This paper investigates the possibilities in the area of application of mobile technologies for language learning. The primary goal is to design a mobile system for learning of the Japanese language with a clear separation of content and presentation, and to leverage the learners' interest in the Japanese language. Both the technical and the language learning perspectives are discussed. A reusable, lightweight model of learning objects with compact content and a reduced metadata set is presented. These objects are stored in a simple learning object repository that can deliver them to any client over the Internet. A mobile application is designed to use the learning object repository as its content provider, while defining its own method of presentation suitable for smaller screens of mobile devices. For the purpose of evaluation, an experiment was conducted within the e-learning system at the Faculty of Organizational Sciences, University of Belgrade. Research findings have indicated that the developed mobile application has a positive effect on the students' interest in the subject matter.

Evaluation of mobile assessment in a learning management system

AbstractThis article discusses the problem of using and delivering educational content from the Moodle learning management system to mobile devices. The primary goal of this study was to investigate the students' habits, motivations and technical possibilities in order to incorporate mobile‐learning activities in the e‐learning process. A mobile quiz has been chosen as an activity to be delivered on mobile devices. The developed mobile quiz application was integrated into Moodle. The application interface was tailored to various types of mobile devices aiming to foster mainstreaming of mobile technologies in e‐learning. For the purposes of the evaluation, an experiment was conducted within the e‐learning system at the Faculty of Organizational Sciences, the University of Belgrade. Data were obtained from the students who attended e‐learning courses in the area of e‐business. Research findings have shown that integration of the mobile quiz application into Moodle improves students' results and increases satisfaction and motivation for using mobile devices in their learning process.

Integration of web based environment for learning discrete simulation in e-learning system

This paper proposes a new web-based environment for learning discrete simulation. FONWebGPSS is an application that provides a web-based interface for creating, storing and executing discrete system simulation models in the GPSS language. The primary goal of the paper is to improve the process of learning simulation by integration of the FONWebGPSS in the existing e-learning system, Moodle. Evaluation of the developed integrated solution for learning simulation has been performed within an undergraduate course, Simulation and simulation languages, at the Faculty of Organizational Sciences, University of Belgrade on a testing sample of 208 students divided into an experimental and a control groups. The research results show that students achieve better results on the final test when using the FONWebGPSS application integrated into the e-learning system in comparison with the standard desktop version of the GPSS.

CRM E-GOVERNMENT SERVICES IN THE CLOUD

Customer relationship management (CRM) is a business strategy whose outcomes optimize profitability, revenue and customer satisfaction by fostering customer satisfying behaviors and implementing customer-centric processes. CRM is often seen as a key element in delivering customer-centric services. Today CRM solutions are often implemented as a cloud computing service. Cloud computing refers to providing and using computational resources via the Internet. It enables the access to technology in the form of service on demand. Services and data coexist in shared and dynamically scaled set of resources. E-government is the organic combination of information technology and government management function. With the development of information technology, government has been upgrading from management-oriented mode to service-oriented one. Therefore, government CRM is a business strategy to provide comprehensive service from all public organizations. This paper presents a model of CRM in e-government system. Model includes process specification, metrics for evaluation of the system performance and recommendations for implementation. 1 Marko Vulic was born in 1985, in Belgrade, Serbia.

THE IMPACT OF APPLYING THE CONCEPT OF THE SEMANTIC WEB IN E-GOVERNMENT

Together with the development of science and technology demands of society as well as people's needs are changing. These changes affect all areas of human activity in particular those related to electronic business. One aspect of interaction that has been affected by these changes is the interaction within the government. It is precisely these requirements which imply the development of an E-government. This Web based technology which is being used by the government as a communication channel is becoming more and more advanced. The complexity and the amount of information included in the communication channels requires the application of a new business concept used by the E1 Lidija Paunovic is PhD student at Faculty of Organizational Sciences, University of Belgrade.

It is in these systems that the Semantic Web found it's use. This paper explores the impact of innovative concepts of the Semantic Web in Egovernment systems. The importance of Semantic Web technology, in this context, is to provide a basis for effective and efficient exchange of knowledge and information in order to coordinate business processes. Research results show that the Semantic Web promotes and improves communication between citizens and the E-government through interoperability. It is the ability of heterogeneous systems to work together, so that the information could be shared without the requirement of additional operations so the two systems could communicate, which is an essential element of any E-government. The lack of interoperability is a source of unnecessary costs well as monopoly. On the other hand the results show that potential problems may arise due to application of services based on the Semantic Web, but also that these shortcomings can be regulated with further development of E-government. The results of this paper may form the basis for further development of E-government and its services. Guidelines are given for the enhancement of quality of the processes in the usage of Semantic Web in E-Government but also in the improvement of potential negative impacts the application of this concept may have on business.

Adjusting Felder-Silverman learning styles model for application in adaptive e-learning

This paper presents an approach for adjusting Felder-Silverman learning styles model for application in development of adaptive e-learning systems. Main goal of the paper is to improve the existing e-learning courses by developing a method for adaptation based on learning styles. The proposed method includes analysis of data related to students characteristics and applying the concept of personalization in creating e-learning courses. The research has been conducted at Faculty of organizational sciences, University of Belgrade, during winter semester of 2009/10, on sample of 318 students. The students from the experimental group were divided in three clusters, based on data about their styles identified using adjusted Felder-Silverman questionnaire. Data about learning styles collected during the research were used to determine typical groups of students and then to classify students into these groups. The classification was performed using data mining techniques. Adaptation of the e-learning courses was implemented according to results of data analysis. Evaluation showed that there was statistically significant difference in the results of students who attended the course adapted by using the described method, in comparison with results of students who attended course that was not adapted.
