Abstract.A key promise of narrative-centered learning environments is the ability to make learning engaging. However, there is concern that learning and engagement may be at odds in these game-based learning environments and traditional learning systems. This view suggests that, on the one hand, students interacting with a game-based learning environment may be engaged but unlikely to learn, while on the other hand, traditional learning technologies may promote deep learning but provide limited engagement. This paper presents findings from a study with human participants that challenges the view that engagement and learning need be opposed. A study was conducted with 153 middle school students interacting with a narrative-centered learning environment. Rather than finding an oppositional relationship between learning and engagement, the study found a strong positive relationship between learning outcomes and increased engagement. Furthermore, the relationship between learning outcomes and engagement held even when controlling for students' background knowledge and game-playing experience.

Targeted as a highly desired skill for contemporary work and life, problem solving is central to game-based learning research. In this study, middle grade students achieved significant learning gains from gameplay interactions that required solving a science mystery based on microbiology content. Student trace data results indicated that effective exploration and navigation of the hypothesis space within a science problem-solving task was predictive of student science content learning and in-game performance. Students who selected a higher proportion of appropriate hypotheses demonstrated greater learning gains and completed more in-game goals. Students providing correct explanations for hypothesis selection completed more in-game goals; however, providing the correct explanation for hypothesis selection did not account for greater learning gains. From the analysis, we concluded that hypothesis testing strategies play a central role in game-based learning environments that involve problem-solving tasks, thereby demonstrating strong connections to science content learning and in-game performance.

Within the intelligent tutoring systems community, narrative is emerging as an effective medium for contextualizing learning. To date, relatively few empirical studies have been conducted to assess learning in narrative-centered learning environments. In this paper, we investigate the effect of narrative on learning experiences and outcomes. We present results from an experiment conducted with eighth-grade middle school students interacting with a narrative-centered learning environment in the domain of microbiology. The study found that students do exhibit learning gains, that those gains are less than those produced by traditional instructional approaches, but that the motivational benefits of narrative-centered learning with regard to self-efficacy, presence, interest, and perception of control are substantial.
