CommonTown’s research team took the stage at the 20th Pacific-Rim Objective Measurement Symposium (PROMS 2025) hosted by Singapore University of Social Sciences, presenting their groundbreaking paper “Game Leveling Using the Rasch Model”. Drawing on data from 700 K–Grade 7 learners across Singapore and Turkey, the study demonstrated how adaptive vocabulary games can be precisely calibrated using the Rasch partial credit model to deliver just-right challenges and maximize student engagement.

At PROMS, attendees from top Asia-Pacific universities and research institutes buzzed around CommonTown’s poster, intrigued by:

• Five innovative game formats (The Wall, Quick Speak, Word Safari, Word Finder, Word Catacombs) mapped to CEFR levels A1–B1
  
  
• Robust item hierarchy : high item separation (5.36) and reliability (0.97) confirming games span a broad difficulty spectrum
  
  
• Key insights on person measurement : diagnosing low person separation (0.53) to inform strategies for boosting learner interaction
  
  
• Unidimensionality confirmation : 75 % primary variance supporting a single English-ability construct for streamlined scoring
  
  
• Actionable refinements : targeted recommendations for mis-performing challenges, ensuring vocabulary games stay both engaging and pedagogically sound

Faculty and fellow measurement specialists praised CommonTown’s blend of rigorous psychometrics with real-world game design, envisioning how this approach can power truly adaptive learning ecosystems.
