In this paper, we describe a My-Pet-My-Quest system to help students establish their learning goals. Digital games often provide students with more controls and clear goals. Therefore, when learning tasks can be integrated with a game structure as a motivating educational environment, students might learn better and with more joyfulness. The My-Pet-My-Quest system that adopts quests to integrate a game structure with a series of learning tasks is proposed to this end. A preliminary experiment was conducted in two elementary classes to assess the quest design. The result reveals that game quest had a positive perception in terms of enjoyment, goal content, goal intensity, and feedbacks. Meanwhile, game quest also stimulated students to attempt more learning tasks.
