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.

Друштвени медији представљају неизоставни део модерног друштва и веома значајан облик социјалне интеракције. Друштвене мреже, као важан део дигиталних медија, одликује једноставно учешће корисника и бројност садржаја које они генеришу. Због значаја друштвених мрежа у промоцији услуга, посебно у туризму, предмет анализе у овом раду су могућности промоције српских манастира на Facebook-u као једној од најзаступљенијих глобалних друштвених мрежа. Анализирали смо Facebook странице десет манастира и утврдили да постоје значајне разлике у ажурности, структури садржаја који се постављају и активности самих корисника, односно пратилаца посматраних Facebook страница.
