This research presents a comprehensive framework and system architecture for a virtual universe to enhance teamwork skills through collaborative learning. A systematic review of 17 research papers from 1998-2024 identifies eight essential components of virtual learning environments: virtual environment, interactive tools, communication features, task-based activities, role-playing scenarios, real-time collaboration, performance assessment, and feedback systems. The proposed three-layer system architecture integrates infrastructure, learning processes, and assessment components to support effective collaborative learning. Expert evaluation involving 50 professionals, including educational technology experts, instructors, and system developers, demonstrated high effectiveness across all components (overall mean = 4.56/5.0, SD = 0.45), with 85% of features fully implemented. The framework incorporates sequential learning processes, including orientation, team formation, role assignment, project planning, collaboration, discussion, assessment, and reflection. The results indicate that the proposed virtual universe effectively supports the development of critical teamwork competencies, including communication, coordination, problem-solving, and leadership skills. This research contributes to advancing educational technology by providing a systematic approach to designing virtual collaborative learning environments that foster essential teamwork skills among learners.
