"The main objective of EUROB+G has been to promote interest among girls in the New Technologies sector through robotics and in an inclusive way; that is, making boys and girls work together to learn to value each other's capacity in the sector. This is a fundamental sector in the society of the future but with minimal female presence, so women are excluded from it and almost 50% of the talent in this area is lost.We wanted to participate in breaking the digital gender gap.To achieve this, we have looked for motivating activities, choosing the cooperative work of building robots and a Smart City that the students involved in the project have worked on. The choice of building a Smart City has extended our project, as it has also led us to develop a decalogue of sustainability for the cities of the future.Communication has been maintained throughout the project and in international meetings, having improved the levels of achievement in Key Competences for lifelong learning, especially in STEM subjects and foreign languages. In addition, Spanish and Slovenian cultures have been brought together; given the cultural diversity between the partner countries, we consider it essential that our students have learned about the cultural and historical heritage of the other country, so cultural activities have been incorporated into the international meetings.EUROB+G has used ""An Active Methodology"". Using a change of roles with the figure of ""peer tutoring"" from the idea of ""learning by teaching"". Thus, students from 15 to 18 years old from Celje school, with extensive experience in robotics, have been mentors for Spanish students from 11 to 14 years old. In view of the need for female role models, girls and women have been present both among the teaching staff and among the pupils playing the role of ""mentors"".During the project, there has been regular communication between pupils in the two countries to coordinate their work in the workshops, using the eTwinning and other environments. The work that has been carried out in the project has been aimed at preparing the workshops for the planned international meetings, in which the students have completed their tasks working in teams made up of pupils from the two countries.The result has been a two-year teaching programme for lower secondary robotics workshops with activities that promote the idea of ""learning by teaching"".The documentation obtained is available on the project's blog, and can be used by any teacher or external organisation interested in this teaching-learning model. The expected impact on the digital and technological gender gap can be seen especially in the increase of female students who have voluntarily chosen the Computing and Robotics subject in the Spanish school. We consider that this impact has been greater in Spain due to the age of the students we have worked with and not due to the work of the Slovenian teaching staff who have been very involved. We believe that at the age of the Slovenian students, students have already discarded options while in Spain we have shown the world of robotics to students who are still open to choose this sector."
