Abstract:In order to keep pace with the ongoing changes in ICT and increasing common IT competencies requirements, informatics curricula at secondary school level and, consequently, curricula educating informatics teachers must be frequently changed to ensure necessary competencies. This paper proposes collaborative development of informatics curricula assisted by a software tool for compatibility analysis of secondary school informatics curricula and curricula by which teachers of informatics are educated. The proposed software tool relies upon semantic technologies, i.e. ontologies for representation of competence-based curricula and ontology alignment for compatibility analysis. The secondary school informatics curriculum ontology was built to comply with the ACM K12 standard, while the teachers' curriculum ontology was built based on the selected existing curricula. The paper presents a brief description of the software tool and the results of the domain (informatics) segment of teachers' curriculum offered by the selected Serbian university and the standardized ACM K12 compliant secondary school informatics curriculum.

In this paper, we obtain the results of coincidence and common fixed points in b-metric spaces. We work with a new type of multivalued quasi-contractive mapping with nonlinear comparison functions. Our results generalize and improve several recent results. Additionally, we give an application of the obtained results to dynamical systems.

This paper discusses the application of modern information technologies to complement communication between educational institutions and students. Communication is important for development and improvement of the quality of the education system. In place of direct communication, educational institutions sometimes need to make additional educational materials available to students. Information technologies play an important role in distribution of these materials. Students have access to personalised and relevant information at any time, as well as many ways and opportunities to clarify any doubt in a quick, easy and efficient way. This paper explains multiple applications of the educational content distribution. It includes reviews of different web-based services, such as a video distribution platform, a portal designed for scientific research and an application for the Android operating system for delivery of different kinds of content of interest to higher education students.

The development and deployment of high technology is a key driver of economic growth, a source of competitiveness, high value-added creation and the creation of well-paying jobs, both in developed countries and in countries in different stages of development. With this in mind, the paper follows the implementation of the sectoral approach followed by the High-technology industry to measure economic performance and the current contribution of the High-technology industry to economic development in Serbia. First, the economic importance of the high-tech industry in the European Union is explored, and then the development of the high-tech industry in Serbia from a development perspective in the future. The concluding part of the paper outlines the measures of active economic policy that must be implemented in order to accelerate the development of the domestic High-technology industry and to make it really the basis for the economic and overall social development of Serbia in the coming decades.
