The project is developed in six educational centers in six different European countries. The coordinating country is the Spanish center and the other centers are located in Sweden, Greece, Portugal, Germany and Poland.The profile of these organizations is diverse. On the one hand, we looked for centers where robotics were established and worked to teach other countries how to proceed and move forward in the methodological change. On the other we needed the experience in active methodologies to be able to work with technological projects that gave more importance to the student's role in the teaching-learning process and to collaborative work. Finally, it was necessary for the centers to have the restlessness and organizational viability to be able to implement the technology in the day to day of their respective curricular programs.Priority Objective:We seek a methodological change through the implementation of technology in the day-to-day teaching of Mathematics and Science. More specifically, we contemplated the possibility of teaching Mathematics and Science through educational robotics.The specific objectives of the project are:1-Improvement of Maths results.2-Provide the necessary technological tools for the acquisition of mathematical concepts.3-Increase communicative competence in English.4-Share good living practices in the centers.Activities carried out and products obtained:In order to develop the project we created a methodological guide with worksheets on which mathematical concepts will be worked through robotics.We have also developed a multilingual dictionary so that communication during transnational activities is fluid.We have also learned to use Scratch, Lego Wedo and Lego Mindstorms by creating games and activities with Scratch and robot prototypes with Lego, in order to recreate real-life situations and solve challenges that society poses.To learn about the different cultures of the participating countries, we have made videoconferences and plastic activities that have been shared in the transnational meetings.The results achieved are summarized in greater knowledge of the application of robotics in the classroom, increasing the level of Mathematics in students and the motivation of our students towards the area, improving the communicative level of English and sharing good practices on coexistence that establish new organizational models for the improvement of the students' work environment.Dissemination and impact:We have carried out dissemination activities such as exhibitions, talks and participation in congresses, where visibility was given to the project and the work carried out within the environment of each center, at the neighborhood, local and regional level.The website has been the place where all the activities have been hosted. It was created at the beginning of the project.The main impact is due to the implementation of technology, either as a subject or as a methodological resource because it has led to organizational changes, modifications to the time allocation for each subject, changes in the professional profiles needed in the centers, etc. It should be mentioned that the impact of the use of educational robotics has opened the mind towards new methodological strategies in centers where programming language or robotics kits had never been used.The sustainability of the project in the future will be based on continuing to develop materials and implement them in the classroom. Since each center has found the space to develop the activities created, this work will continue in the future looking for new and better results.The centers remain in contact and will continue to evaluate the impact of the project and will even work for new initiatives that arise to re-participate in future Erasmus projects that return to bring quality to their educational offer.
