The DIGITECH project is an Erasmus+ project aimed at developing digital and information technological competences for teachers in primary and secondary schools in the context of the COVID-19 crisis and the energy transition. The project focuses on improving teachers' digital skills and increasing their ability to teach students digital skills in all subject areas, with a particular emphasis on sustainability and energy transition. The project aims to train teachers to work with digital tools after the pandemic and to improve and strengthen digital educational tools to make them more sustainable, future-proof, and pandemic-proof. The project will last for two years and involve the exchange of knowledge and co-creation of digital teaching methods through digital platforms and regular partner meetings. The project will result in teachers and students having learned how to adapt their teaching to the needs of Industry and Digitalization 4.0 and optimal use of digital tools available. The content of the developed toolbox will have been improved to optimally stimulate the digital skills of both teachers and students, and the lessons learned will be disseminated in the four participating EU member states.
