A Domain Specific Language to retrieve objective indicators for foreign language learning in virtual worlds
0 likes528 views
The document presents a domain-specific language called Virtual Worlds Query Language (VWQL) designed for retrieving objective indicators for foreign language learning in 3D virtual environments. It discusses the implementation of VWQL within the OpenSim virtual world engine and outlines a case study focusing on a German language course where students engaged in a collaborative shopping task. The authors conclude by highlighting VWQL's ease of use and the potential for future extensions to enhance language assessment.

- 2. Contents ● Introduction ● Design and architecture ● Proposal ● Case Study – Settings – Hypothesis – Analysis ● Conclusions
- 3. Introduction ● Foreign language courses (ECTS) – few hours of language practice in class – many hours of independent learning ● We use 3D virtual worlds to: – Encourage independent learning – Provide a fun and “natural” learning environment ● Issues with monitoring and assessment: – Aim: make learning analytics available for everyone
- 4. Introduction Some game worlds we implemented for language learning:
- 5. Design and architecture ● We use the Opensim virtual world engine – Well-known reliable open source – Client-server approach
- 6. Design and architecture ● We use the Opensim virtual world engine – Interesting game information is stored – Programming skills are needed to get it SQL + script
- 7. Design and architecture ● We use the Opensim virtual world engine – We propose using a Domain Specific Language to retrieve information from students' interaction in Opensim Virtual Worlds VWQL
- 8. Proposal ● Virtual Worlds Query Language (VWQL) – Model-drive approach (xtext + EMF) → EvalSim – Syntax: Evidence name_of_the_evidence: get students [id_of_the_student] show ( words [dict] | sentences | single | turns | time | points )+
- 9. Proposal ● Hypothesis contrast / indicator refinement cycle Initial proposal VWQL query Satisfies? submit reply NO YES analyze refine
- 10. Case study: settings ● German as a second foreign language course – 5 students (B1 CEFR) participated ● Virtual world implements a joint shopping task: – Two players: client and shop-assistant – Coordination communicating via text-chat
- 11. Case study: hypothesis ● Skill: – make themselves understood in the foreign language ● Following hypothesis was established: – A student had difficulties to make himself understood if he needed 2+ sentences, per turn, to communicate with his teammate ● Initial proposed query: Evidence time_sentences: get students show time , sentences

- 13. Case study: refinement ● Refined query: focus on sentences and turns rather than on time and sentences Evidence sentences_turns: get students show sentences , turns
- 14. Case study: second analysis Student Average of sentences per turn Student1 1.83 Student2 2.00 Student3 2.14 Student4 4.10 Student5 2.00
- 15. Conclusions ● We have defined VWQL, the first Opensim virtual world Specific Language – Easy syntax, no programming skills needed ● We proposed a refinement cycle to scale monitoring or assessment – It was applied to a simple case study ● Future work: extend the language to identify exclamations, Wh-questions, etc.
