Development of a Web-Based Adventure Game for Teaching Chemical Bonding to Senior High School Students

The abstract nature of chemical bonding concepts poses a significant challenge in senior high school chemistry education. To address this, we developed a web-based adventure game as an innovative instructional medium for teaching covalent bonding, moving beyond conventional drill-based approaches by integrating learning within a narrative-rich, interactive environment. Following a structured methodology, the study began with a requirement analysis, leading to a system design articulated through use case diagrams and flowcharts. The game was subsequently implemented using Unity, PHP, and MySQL, resulting in a functional prototype featuring explorable worlds where players complete missions by answering questions on covalent bonding. Testing confirmed that the game met all specified functional requirements. The results demonstrate that this game successfully transforms abstract chemical principles into a tangible and engaging learning experience through its contextual challenges and score-based evaluation system. It is concluded that the implementation of a story-driven adventure game holds significant potential for bridging the representational gap in chemistry education, effectively enhancing student engagement and conceptual understanding. This research provides a strategic alternative for educators, offering a game-based learning tool that is both accessible via web browsers and aligned with the proficiencies of digital-native learners.
