This study seeks to identify and describe believable and probable scenarios about the future engagement of children in cyberspace from the perspective of futures studies. Children's and adolescents’ access to the Internet and network-based technologies is becoming increasingly prevalent. So explaining the key factors and uncertainties affecting this phenomenon requires a comprehensive insight into current and emerging trends and the change drivers. For this purpose, after reviewing several useful technological and social trends, using scenario-based planning methodology, questionnaire tools and expert panel, 28 effective factors, ten key factors, and five driver forces (with uncertainty) were identified. Then, structural analysis and scenario logic explanations have been performed by Micmac, Scenario wizards, and cross-impact matrix analysis. Accordingly, the four scenarios of “salmon in the pool”, “salmon in the river”, “guppy in the tank”, and “goldfish in the pond” have been identified and narrated for the future of Iranian children's engagement in cyberspace. The findings of this study provide a more comprehensive understanding of believable futures while emphasizing the importance of engaging and addressing the interests of audiences and the needs of stakeholders in designing relevant strategies and broadening the horizons of decision-makers toward future alternatives.
