GrammarWorld: Entorno Virtual de Aprendizaje basado en juegos para la enseñanza de Gramática Inglesa nivel A1-A2

Abstract

Abstract: This capstone project presents the development of *GrammarWorld*, an immersive educational video game designed to teach English grammar at the A1 A2 proficiency levels. Built using the Unity engine and deployed on the Spatial platform via WebGL, the project developed using the SUM methodology features a level called "Syntaxia." This level comprises three core activities: *Sentence Builder Bridge* (focusing on word order), *Verb Volcano* (covering simple verb tenses), and *Preposition Maze* (addressing prepositions). These activities are integrated into a guided narrative, supported by adaptive feedback and a reward system. The project was validated with 115 university students at the A1 A2 level using instruments to assess usability and technology acceptance. Metrics for perceived utility, hedonic motivation, intention to use, and perceived learning all scored well above the neutral point on the scale (M = 4.02 4.09). In contrast, perceived usability fell into a marginal range (SUS M = 64.0), indicating that initial ease of learning should be a key focus for the next iteration. Learning was measured solely through self-reported perception, without pre- or post-tests of actual knowledge. The results support the relevance of gamified virtual environments as a complementary resource for teaching English grammar.
