Abstract
The game-based learning (GBL) environment is used in performance improvement and formal education very successfully. The study mainly focuses on scenario design for the concept of game-based chain reaction applies to instructional content on natural science & living technology domain of elementary school via conducting the brainstorm in class. The scenario themes include four categories as Risk Precaution, Obstacle Eliminations, Situation Balances, and Confident Challenges. The initial template of scenario begins to create the beginning of chain components with procedure-linked mechanics, and the goal is, then solving the themed problem of situations. The players could be requested to try to arrange the rational and effective components, then in order to produce the chain reactions. The study result hopes to the scenarios for game-based chain reaction to guide learner to enhance the exploratory motivations and learning enjoyments. © 2011 IEEE.
