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

Abstract 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.

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.

High-pressure optical studies on R-line fluorescence lifetime in Al2O3:V2+

ABSTRACT The effect of high hydrostatic pressure (up to 10.3 GPa) at room temperature on fluorescence lifetime τ for R line (2E→4A2 transition) in ruby Al2O3:V2+ was studied. The performed studies show the linear increase of τ with increasing pressure. At 10.3 GPa, τ is about 1.36 times higher than at ambient pressure. The obtained trend was explained by a model which considered the effect of pressure on τ through an induced change of line position, inter-ionic distance, compressibility, and molecular polarizability. A good agreement between the calculated and experimental values for τ was obtained.
