Sustain City

Recent years have witnessed a growing interest in interactive narrative-based serious games for education and training. A key challenge posed by educational serious games is the balance of fun and learning, so that players are motivated enough to unfold the narrative stories on their own pace while getting sufficient learning materials across. In this chapter, various design strategies that aim to tackle this challenge are presented through the development of Sustain City, an educational serious game system that engages students, particularly prospective and beginning science and engineering students, in a series of engineering design. Besides narrative-learning synthesis, supplementing the player's actions with feedback, and the development of a sufficient guidance system, the chapter also discusses the integration of rigorous assessment and personalized scaffolding. The evaluation of Sustain City deployment confirms the values of the serious games in promoting students' interests and learning in science, technology, engineering, and mathematics (STEM) fields.
