<< Objectives >>The We Teach DATA project aims to enhance ISCED level 2 students’ key competences, STEM teachers' teaching competences and professional development, and contribute to the modernisation of the STEM education through the development, testing, piloting and promotion of a set of comprehensive innovative learning materials and trainings for teachers, with focus on data science and cross-curricular instruction. This will be achieved as a transnational collaboration between 7 partners from 4 countries.<< Implementation >>The activities will be implemented in WPs dedicated to: coordination and communication, monitoring, evaluation, risk management and budget control; development and conducting of a joint staff training; development, testing, digitalisation, translation and piloting of a School Box a Master Class for STEM teachers a Training of Trainers; and implementing a comprehensive sharing and promotion campaign. We will apply the principles of innovation development through co-creation.<< Results >>Apart from the tangible results from each WP, we expect to benefit 600 students at ISCED level 2, 30+ STEM teachers and 2500 key stakeholders (during the project lifetime only and many more afterwards). Some of the intangible outcomes are: enhanced key competences (digital competence: information and data literacy; communication and collaboration; digital content creation; problem solving), teaching competences, professional development, awareness levels, quality and relevance of STEM edution.
