In many cases, the informal education of young people has played a key role in shaping attitudes and decisions about their future (Dieker, L. et all, 2012). Summer camps are undoubtedly additional opportunities for children to learn new and interesting topics, which later might become their choice for a more in-depth study and specialization. Short-term STEM and robotic summer programs are quite popular in various parts of the world (Capelli et al. 2019). The main goal of these kind of camps is the enjoyable and creative employment of children through programs that offer them the opportunity to gain experience about recent technologies such as Robotics, programming, 3D printing and other creative activities. This paper aims to highlight some critical parameters of a pedagogical framework that could be used for building up successful STEM camp programs. Moreover, a questionnaire which examines how dimensions like confidence, content knowledge, persistence, ease of use of the robotic platforms and the satisfaction of the participants aging 9-14 has been created and pilot evaluated during this case study.
