Ε3 STEM (www.e3stem.edu.gr) is a professional community of University Professors, School Educators, and School Advisors who share a common vision for the role of STEM epistemology in promoting education. Ε3 STEM engages in the development of open STEM and STEAM applications based on the interdisciplinary and transdisciplinary epistemological approach combined with didactics models, like the Inquiry teaching and learning approach for science education. It aims to promote computing pedagogy, physical computing, computational science, didactics of science and computational thinking, and to advance understanding and the pedagogy of the STEM methodology alongside contemporary learning theories and didactic models. E3STEM members work also for the inclusion of Art in STEM in an interdisciplinary and trans-disciplinary approach as an approach to teaching in which learners are engaged in conceptual understanding through an art form(e.g. by developing robotic artifacts, narrative stories using WEB 2.0 tools etc implementing the so-called studio learning). E3STEM also offers accredited seminars in teachers’ training for STEM and STEAM education for pre-service and in-service teachers and has the capacity to train teachers in large-scale programs. E3STEM has the capacity not only to develop software applications but to be engaged in hardware development. More than 120 members are included in E3STEM creating a strong network of teachers, school advisors and University Professors where STEM applications can be implemented. E3STEM has been established only for two years but its members have the capacity to push forward the STEM education since members are University Professors, Education Work Coordinator for Educational Planning-a role resembling the role characterized previously as school advisors), experienced teachers and education researchers. Despite the fact of the small-time period of its existence E3STEM participates in one Erasmus project (INDIE) while its members have been involved in European and National projects on behalf of their organizations. E3STEM supports the newly established journal Hellenic Journal of STEM Education http://www.hellenicstem.com/index.php/journal

The Slovak University of Technology in Bratislava (Faculty of Architecture and Design, STUBA) is a modern educational and scientific institution. Since its foundation in the year 1937 more than 115.000 students have graduated. On average, 19.000 students study at the STU every year. At present, the STU consists of seven faculties. All the STU faculties provide a study in accredited study programs within the complex system of a bachelor, master and PhD studies. Faculties realise credit system compatible with the European credit transfer system enabling mutual mobility of students within European Union member countries and a larger European space. In the area of scientific and research activities, the STU successfully joins European Union programs. The Slovak University of Technology in Bratislava (hereinafter referred to as "STU") is a modern educational and scientific institution. The ambition of the STU is to contribute to extending knowledge through its acquisition from science and to foster its dissemination via education as well as its application in direct cooperation with industry. The Faculty of Architecture and Design of the Slovak University of Technology Bratislava (FASTU) is the largest educational institution for architects in Slovakia, which provides education in architectural, interior and industrial design within the bachelor, master and doctoral programmes.

Felix is a private primary and secondary school in Bratislava. The founders of the school are people with rich experience involving the work with children not only in school, but also elsewhere. Their work also involves creating a network of innovative teachers across Slovakia. In Felix, they want to put their experience and also inspiration from the best teachers into practice. Our mission is to help children to become good, wise and confident - therefore happy people. We are systematically working on the development of their motivation for learning and self- development. We respect their emotionality and we support the positive perception of themselves and people around them. We encourage their prosocial behaviour and we try to incorporate the development of the life skills into the process of education. In Felix, there are 230 pupils and 13 classes. There are 40 employees (12 non-pedagogical employees). Lots of parents of our pupils are actively involved in the life of our school.
