This design case describes design decisions and their impacts during three redesigns of an educational game called the “Rocks and Minerals Challenge.” This game was developed as a laboratory supplement for the rocks and minerals component of a university-based geology course. The game has evolved through three distinct design phases: Design 1, first designed as a challenge module in 2005; Design 2, redesigned as a game in 2012 for compatibility reasons; and Design 3, redesigned in 2015 to enhance instructional effectiveness. Following is a description of the game design factors that were implemented for each of the design phases: learning goals, levels of challenges, scaffold-ing, user control, feedback, and rules. The timing, rationale and impacts of these design decisions are discussed within the context of recommendations identified by existing educational game research. |
