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!

โ€œThe current โ€œdigital game generationโ€ challenges traditional classroom teaching. Gamification is often presented as a solution. However, few have spoken so far about game-based learning. Itโ€™s important to recognize the distinction between gamification and the use of games popular among young people and children in educational contexts: gamification refers to the use of of game-mechanisms/elements in everyday situations (in this case, learning), whereas game-based learning concepts are built around games that were originally designed for leisure activities, i.e., outside of a formal context. While in gamification, game elements are introduced into an environment originally created for learning in order to overcome the barriers of a formal learning situation through playful means and to motivate learners, game-based learning enables meaningful learning as a sort of โ€œby-productโ€ of the main activityโ€”namely, playing a real computer game. Sometimes, gamification does not succeedโ€”the learning game used may be too simple or artificial, or it might be based on behaviorist principles that are now considered outdated. On the other hand, there are also successful examples of gamification (cf. Pihkala-Posti 2016). Game-based learning, in contrast, aims to introduce novel learning materials and habits, and to facilitate access to learning goals through flow-experiences, among other things. However, this requires careful didactic preparation.โ€ Translation from the German original: Elina Hongisto

“Die aktuelle โ€žDigispielgenerationโ€œ fordert den schulischen Unterricht heraus. Als Lรถsung wird oft Gamification angefรผhrt. Von spielbasiertem (game-based) Lernen reden bisher wenige. Jedoch ist es wichtig zu erkennen, dass zwischen Gamification und der Nutzung von bei Jugendlichen und Kindern beliebten Spielen im Bildungskontext unterschieden werden muss: Bei der Gamifizierung handelt es sich um die Verwendung spielerischer Elemente in einer Alltagssituation (im Bildungsbereich beim Lernen), aber Game-based-Learning-Konzepte basieren auf Spielen, die ursprรผnglich fรผr Freizeitaktivitรคten, also auรŸerhalb des formellen Kontextes erstellt wurden. Wรคhrend bei Gamification Spielelemente also in eine ursprรผnglich fรผr das Lernen geschaffene Umgebung eingefรผhrt werden, um mit den spielerischen Mitteln die Hรผrden einer formellen Lernsituation zu รผberwinden und die Lernenden zu motivieren, wird beim Game-based Learning in gewisser Weise als โ€žNebenproduktโ€œ der Haupttรคtigkeit, das heiรŸt des Spielens, etwas Sinnvolles gelernt. Manchmal gelingt die Gamification nicht – das einzusetzende Lernspiel mag zu einfach oder gekรผnstelt sein, eventuell basiert es auch auf behavioristischen Prinzipien, die als รผberholt anzusehen sind. Andererseits gibt es auch gelungene Beispiele fรผr Gamification (vgl. Pihkala-Posti 2016). Beim spielbasierten Lernen zielt man wiederum darauf ab, neuartiges Lernmaterial und neue Lerngewohnheiten zu erwirken und den Zugang zu Lernzielen unter anderem durch Flow-Erlebnisse zu fรถrdern. Dies erfordert jedoch sorgfรคltige didaktische Vorarbeit.”

Project approaches / Projektansรคtze

In the Excalibur project we developed and used different approaches:

  1. 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

Im Rahmen des Excalibur-Projekts wurden verschiedene Ansรคtze entwickelt und eingesetzt:

  1. Plain World (Weltenbau ohne Vorgaben / Flachlandwelt)-Setting in Minecraft
    • Die Lernenden diskutieren gemeinsam รผber das vorgegebene (oder gewรคhlte) Thema und darรผber, was sie im Vorfeld รผber das Thema/die Themen wissen.
    • Auf der Grundlage von Diskussionen, kritischem Lesen (der Umfang hรคngt von der Zeit ab, die zur Verfรผgung steht) und Besprechungen sowie gemeinsamer Entscheidungsfindung bauen die Lernenden die Objekte in der 3D-Welt.โ€‹
    • AnschlieรŸend beschreiben sie, was sie getan haben, und prรคsentieren ihre Arbeit. AuรŸerdem berichten sie, was sie รผber die interkulturelle Kommunikation und das/die jeweilige(n) Nachhaltigkeitsthema/-themen gelernt habenโ€‹

Project cases

Example case: Sustainable Tourism – Finland & Italy

Collaborative Sustainable Tourism Project in Minecraft โ€“ A Partnership Between Finnish and Italian High Schools 

In this educational project, high school students from Finland and Italy teamed up to create sustainable tourism environments in Minecraft. The project, titled Sustainable Tourism Environments in Minecraft, spanned six weeks and focused on designing and simulating eco-friendly tourism practices that could reduce the carbon footprint of the travel industry. By collaborating online, the students not only built a virtual world but also learned about sustainable practices and their real-world implications. 

Getting Started The project began with teachers from Finland and Italy meeting online to establish the overall project goals and roles for students, later continuing with ice-breaker activities to help students from both schools connect. Through video calls and online chat, the Finnish and Italian students exchanged ideas, asked ice-breaker questions, and discussed their interests. These initial discussions laid the foundation for a structured and purposeful collaboration between the two schools. 

Activities: 

  • Establishing project goals centered on sustainability and tourism. 
  • Allocating team roles: Finnish students were assigned research and communication tasks, while Italian students focused on building and design within Minecraft. 

Collaborative Research and Design in Minecraftโ€ฏsaw students engage in research and practical design. The Finnish students took the lead in scientific research and analysis, studying sources on energy-saving methods, geo-resource reduction, and eco-friendly tourism strategies. The Italian students, meanwhile, focused more on the creative aspect, preparing to take on active roles in building the virtual tourism environments. Students planned the activities and building in the Minecraft world collaboratively, ensuring alignment between research and design. 

The Finnish students shared their findings with their Italian counterparts, providing scientific data that would inform the building process. During this phase, both groups also learned how to identify credible sources and analyze their reliability, guided by their teachers. 

Highlights: 

  • Research on sustainable tourism, covering topics like energy efficiency, waste reduction, and water conservation. 
  • Student-driven planning and construction of eco-friendly facilities in Minecraft, such as: 
    • Renewable Energy Hub: A central area with solar panels and wind turbines to provide renewable energy to the virtual tourism sites.  
    • Eco-Friendly Accommodations: Hotels designed with green certifications, including features such as energy-efficient lighting and water conservation systems. 
    • Waste Reduction Centers: Recycling and composting stations to minimize the environmental impact within the virtual world. 

Challenges: 

  • Addressing cultural and language barriers. 
  • Managing disruptions in the Minecraft world caused by unauthorized access. 

Assessment and Evaluationโ€ฏThroughout the project, the students participated in peer evaluations and feedback sessions. These meetings, facilitated by their teachers, provided opportunities for students to discuss what was working and what could be improved. Creativity, adherence to sustainable principles, and the effectiveness of reducing the carbon footprint were key evaluation criteria.  

The project concluded with a reflection session where both Finnish and Italian students shared what they had learned about sustainable tourism. The discussions were not only about Minecraft but also about the importance of real-world sustainability and how small actions can make a big difference.  

Achievements:

  • Creation of a comprehensive virtual environment showcasing sustainable tourism. 
  • Development of key features such as: 
    • Eco-friendly hotels and restaurants. 
    • A sustainable transportation network. 
    • Conservation areas and carbon offset initiatives.
  • Strengthened international collaboration skills. 

Reflection and Future Plans The project ended with a sense of accomplishment as students saw how they could collaborate across borders to create solutions for real-world problems. The teachers from both schools expressed interest in continuing the partnership, with the possibility of future projects focused on different aspects of sustainability. The Minecraft platform proved to be an effective educational tool, allowing students to apply their scientific knowledge in a creative and engaging way. 

This project was a unique blend of creativity, science, and international collaboration, helping students understand the importance of sustainable tourism and how digital tools like Minecraft can be used to model solutions to environmental challenges.
