Center node: "occurence of a cyber security eco system a nature oriented project and evaluation of an indirect social experiment"
  Abstract: Because of todays technological developments and the influence of digital systems into every aspect of our lives, importance of cyber security improves more and more day-by-day. Projects, educational processes and seminars realized for this aim create and improve awareness among individuals and provide useful tools for growing equipped generations. The aim of this study is to focus on a cyber security eco-system, which was self-occurred within the interactive educational environment designed under the scope of TUBITAK 4004 Nature Education and Science Schools Projects (with the name of A Cyber Security Adventure) with the use of important technologies such as virtual reality, augmented reality, and artificial intelligence. The eco-system occurred within the interactive educational process where high school students took place caused both students and the project team to experience an indirect social experiment environment. In this sense, it is thought that the findings and comments presented in the study will give important ideas to everyone involved in cyber security education, life-long learning processes, and the technology use in software oriented educational tools.
