As the title says, with this project we aim to create one big classroom where all the partners from different sides of Europe work together in different school subjects learning from each other. The project idea was born from the need to combine an eTwinning project with the topic of the interdisciplinary learning modules of Nokia-Vihola school for the school year 2024-25: to learn about different European countries, study their history, nature, culture, languages and find out similarities and differences between them. This eTwinning project is supposed to be a part of our everyday school life throughout the year, and all the classes in partner schools are welcome to take part in its activities. The project also offers our teachers and students authentic possibilities to use English language skills, and a possibility to learn the basics of the national languages of our partners. The activities will mainly be performed using different digital tools. Face-to-face meetings between some of the partners will also be possible with the help of Erasmus+ accreditation of some partners.
