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.

Supply chain intelligence for electricity markets: A smart grid perspective

Smart grid technologies are bringing innovations in electrical power industries, affecting all parts of the electricity supply chain, and leading to changes in market structure, business models and services. In this paper we introduce a model of business intelligence for a smart grid supply chain. The model is developed in order to provide electricity markets with the necessary data flows and information important for the decision making process. The proposed model offers a way to efficiently leverage the new metering architecture and the new capabilities of the grid to reap immediate business value from the huge amounts of disparate data in emerging smart grids. The model was evaluated for the Serbian electricity market in the electric power transmission company Public Enterprise “Elektromreža Srbije”. The results show that business intelligence solutions can contribute to a more effective management of smart grids, in order to ensure that companies achieve sustainability in the increasingly competitive electricity markets, while still providing the high quality services to end users.

Fostering students’ participation in creating educational content through crowdsourcing

ABSTRACT This paper proposes and evaluates a model of crowdsourcing in microlearning that includes the balancing of collaborative learning and crowdsourcing mechanisms. The goal of the research is to implement a learner-centered approach through crowdsourced content creation and to improve the process and outcomes of learning. Crowdsourced content creation was accomplished through a collaborative project within a higher education institution. Micro-courses in the form of short video lessons were created by students and published on the Coursmos platform and a certain group of students attended these micro-courses. The evaluation was carried out at the Faculty of Organizational Sciences, the University of Belgrade on a sample of 71 students who created micro-courses and 74 students who attended these micro-courses. The results show that the developed model provides simple communication and collaboration among students, high level of their self-organization and satisfaction, efficient management of crowdsourcing network and collaborative knowledge building.
