Project EXCALIBUR
EXpanding Content And Language Integrated learning through BUilding a sustainable future in Realtime
Combining CLIL and LOTE with virtual 3D sandbox worlds to find solutions for real-life sustainability challenges

Project description
The theme of the Erasmus+ project EXCALIBUR 2022-2025 (2021-1-FI01-KA220-SCH-000029713) is sustainability. With the help of different communication languages, learners from various countries explored this topic in an intercultural setting. They worked online together in virtual 3D sandbox worlds in order to find innovative solutions to major environmental real-life challenges that unite the contemporary international world.
The EXCALIBUR project combined the approaches of Content and Language Integrated Learning for English (CLIL) and Languages Other Than English (LOTE) to the STEM subjects and the overall theme of sustainability. Furthermore, the learners developed their information and media literacy skills, along with the 6Cs of Deep Learning (communication, collaboration, creativity, critical thinking, character and citizenship). Together, they combined their individual strengths to use their creativity, skills and interdisciplinary knowledge in order to find possible solutions to actual fundamental environmental problems in living environments.
The project partner team coordinated by Tampere University consisted of scientific and pedagogical experts from different European countries with expertise in language learning, virtual and game-based learning, CLIL and CLIL LOTE learning, information retrieval and STEM. The main focus laid on the societal interaction, meaning cooperation with mainly upper secondary schools. There were participating schools from Finland, Germany, Norway, France, Italy and Czechia. The participating learning groups consisted of learners using English, German and French between CEFR levels A2-C2. The groups included smaller subgroups or the whole class.
The learner-centeredness was the key element of the project and the learners were engaged in an intercultural dialogue and creativity. Even informal collaboration opportunities for learners were offered. The project team supported and guided their teachers throughout the project, for example in matters of organization and schedules and offered the collaboration environments and the approaches.
Welcome to follow our innovative project, where we combine virtual game worlds, language learning and sustainability!
Join our network for even further co-operation using the approaches developed during the project!
Sustainability sub-themes in the project
The Excalibur project focused on the following sustainability themes. Depending on the sub-project, these were studied at least in the Plain World Setting approach (cf. Project cases). These themes were drafted by the Tampereen klassillinen lukio Excalibur team and participating students and were complemented together with German, Italian, Czechian and Norwegian partners and associate partners.
- Sustainable buildings and their surroundings
- Sustainable energy solutions
- Sustainable traffic solutions
- Sustainable food solutions
- Sustainable recycling solutions
- Sustainable nature surroundings and supporting the biodiversity of the environment
- Sustainable schools
- Sustainable hospitals
- Sustainable tourism
- Sustainable economy & circular economy
The games used in the project:
Project approaches
In the Excalibur project we used different approaches:
- Plain world setting in Minecraft
- Learners discuss the given (or chosen) theme(s) together and what they know beforehand about the theme(s)
- Based on the discussions, critical reading and negotiations and
mutual decision making, the learners will build the objects in the 3D world - Afterwards they describe what they have done and present their work.
Additionally, they also report what they have learned about intercultural
communication and the sustainability theme(s) in question
- The SERASUM: For a better tomorrow adventure mission in Luanti
- An immersive game adventure designed and made by Landesmedienzentrum Baden-Württemberg
- Learners assume secret avatar identities in order to collaboratively complete missions
- Action based game worlds in Minecraft
- Learners experience a ready-built world, where they encounter sustainability-related issues
- Together the learners discuss the issues, consider possible solutions and based on a common decision, they improve the game environment
- Afterwards reporting tasks
- Making a Learning Story
- A tool to help teachers with structured planning of a 3D building project
- A narrative written by the teacher about the activity, to be carried out by the learners, creating the context in which the learners act
- Includes 5 constants and 7 stages

Education Evenings
In January and February 2025, there were Excalibur project online presentations, the so-called Excalibur Education Evenings. The project team introduced and discussed central topics to the project with the evenings’ participants. The evenings were held in English and in German.
The presentations by the project team were recorded and can be viewed HERE.
