In order for a smooth and problem-free transformation to take place in a digitalizing education system, efficient management is needed. Thus, educational managers need to improve their skills and develop behaviors suitable for taking education systems into the digital age. Social networks enable leaders to become digital citizens by embracing and implementing "Open Leadership". Acceptance of technology and self-efficacy in technological leadership are both seen as factors that can have positive or negative influences on the new leadership styles. This study aims to investigate the relationship between open leadership, digital citizenship, technology acceptance and self-efficacy in technological leadership. Working with a group of 153 education managers, the research was conducted using a relational screening model. Following multiple regression analyses, it was found that technology acceptance and self-efficacy in technological leadership positively influences digital citizenship at medium level and that self-efficacy in technological leadership and digital citizenship positively influences open leadership.

The relevance of the present study is due to the importance of developing creativity which can be achieved through a variety of school subjects including mathematics. In the article the potential of extended (supplementary) mathematical education (in primary and secondary schools) is highlighted. The main objective of this study is to examine and evaluate the contents, practices and methods that are currently employed in extended education. The main empirical method of this study is modeling of the modular system of lessons (the course) that offers a variety of assignments including non-standard tasks, puzzles and problems; tasks and topics from academic Olympiads and other mathematical competitions; creative tasks, practical assignments and experiments with mathematical materials ("empirical" mathematics); team and individual competitions and organization of home readings on a specific subject. The article describes the author's methodology. The main feature of the developed course is the inclusion of various organizational forms and diverse materials aimed at sustaining schoolchildren's interest towards mathematics, enabling them to deal with advanced level mathematical problems and developing their curiosity and creativity. The course "Developmental Mathematics" that is presented in this article has been empirically tested since 2008.
