1. Game-Based Learning: Enhancing Student Experience, Knowledge Gain, and Usability in Higher Education Programming Courses

Author

Abstract

Contributions: This article presents a large-scale study which investigates students' reaction to game-based learning as part of programming courses. The study focuses on knowledge acquisition, learner experience, and game usability. Background: Despite the rapid growth of the information and communication technologies (ICTs) sector, the lack of engagement with science, technology, engineering, and mathematics (STEM) subjects and high dropout rates in computer science and engineering majors is linked directly to the large number of unfilled vacancies in the ICT employment market. To tackle one of the underlying causes for this crisis, (i.e., traditional teaching paradigms struggle to attract students to rather abstract and difficult STEM subjects such as programming), innovative technology-enhanced learning solutions are sought. Intended Outcomes: A set of serious games were proposed and designed to promote students' understanding of programming concepts, improve their confidence, stimulate their interest in STEM and increase engagement with the courses through vivid and appealing scenarios. Application Design: Targeting undergraduate and postgraduate students, the games focused on several key programming topics. They were designed to visualize the programming concepts in illustrative and entertaining scenarios. A comprehensive assessment methodology which includes surveys, observations, and interviews was employed to investigate the impact of the games. Findings: The results show that by using the games in the teaching and learning process all the students have benefited, although differently based on their location, educational backgrounds, and game played. The impact of detailed demographic aspects, such as participants' use of technology, their initial attitude toward school, and learning STEM on the results needs further study.

Abstract

The process of terrestrial digital video and audio broadcasting in European countries started 20 years ago. With video–audio standardization for transmission and coding procedures, a new era was opened in digital technology. The world digital broadcasting with communication research, industries and digital interactive media is now closely linked with computer science, radiocomunications, telecomunications, Internet / World Wide Web. Together with dynamic digital media era and global and regional media regulation it is necessary to develop economic and digital media business model monetization. The main purpose of this paper is to identify present situation in selected European countries, Republic of Croatia and Slovak Republic, and to analyze application of Public-Private Partnership (PPP) models in implementation of digital audio broadcasting (DAB+) infrastructure networks. To introduce PPP it is necessary to define financial method, outsourcing and private property. In this paper we explain the difference between Traditional financing model and the Basic financing PPP project model. The aim of the paper is to present a balanced recommendation for using PPP model among involved parties according to the country specifics. The paper will explain the reasons to switch from FM radio digital audio transmission to DAB+ radio, and point out technological advantages. Usage of DAB+ ensures improved signal quality, higher availability of provided services and cost reduction for transmitter operation and maintenance.

Abstract

An SN (sinusoids plus noise) model is a spectral model, in which the periodic components of the sound are represented by sinusoids with time-varying frequencies, amplitudes and phases. The remaining non-periodic components are represented by a filtered noise. The sinusoidal model utilizes physical properties of musical instruments and the noise model utilizes the human inability to perceive the exact spectral shape or the phase of stochastic signals. SN modeling can be applied in a compression, transformation, separation of sounds, etc. The designed system is based on methods used in the SN modeling. We have proposed a model that achieves good results in audio perception. Although many systems do not save phases of the sinusoids, they are important for better modelling of transients, for the computation of residual and last but not least for stereo signals, too. One of the fundamental properties of the proposed system is the ability of the signal reconstruction not only from the amplitude but from the phase point of view, as well.
