Effectiveness of Educational Virtual Worlds in the Metaverse A Study Based on the ARCS Mode

The digital revolution and the development of Web 3.0 have radically transformed the landscape of education, with virtual worlds and the Metaverse emerging as promising tools for enhancing the learning experience.This study evaluates the effectiveness of an educational virtual world for teaching basic computer technology concepts to middle school students, using Keller's ARCS model.The study involved 60 middle school students (aged 12-15) who attended corresponding courses in a virtual environment in the metaverse Spatial.io.Access to the virtual environment was through the school laboratory infrastructure and only through computers, without the use of specialized immersion equipment such as HDM or specialized VR devices.Data were collected through an ARCS questionnaire with a 5-point Likert scale.All ARCS dimensions showed high scores (Attention: 4.220.84,Relevance: 4.120.76,Confidence: 3.801.02,Satisfaction: 4.240.80).Strong positive correlations were also found between all dimensions (r=0.52-0.74,p<0.01).The educational virtual world proved to be effective in enhancing learning motivation, with the confidence dimension needing further improvement.
