The G-STEAM Academy is a European education partnership aimed at catalysing teacher education policy and practice towards greater gender inclusivity in the teaching of STEM subjects, by bringing together ITE and CPD providers, practice schools and non-formal education and research organizations from 9 different countries (the Netherlands, Greece, Italy, Romania, Spain, Czech Republic, Finland, France, and Luxemburg). The project will establish a European Community of Practice for gender and intersectionality inclusive STEAM education, to advocate for educational policies that support the integration of gender inclusive teaching in ITE, CPD and school curricula and teaching standards, inviting education departments, policy designers and local authorities to co-design strategies, plans and recommendations for institutionalizing gender-sensitive training for teachers. By harnessing the power of creative and arts-based pedagogies, G-STEAM Academy will develop highly innovative educational products (i.e. G-STEAM Toolboxes), joint training programmes, mentoring and mobility schemes that is blended, flexible and appropriate for boosting collaboration among CPD and ITE providers, bringing together teacher trainers, pre-service and in-service teachers at both national and European levels, enhancing the European dimension of teacher education.
