Furthermore, AR provides a situation where reality and fantasy are blended but this mixed reality could cause students’ confusions. In
Klopfer’s (2008) study, some students “lose sight of where the game ends and reality begins” (p. 100). Even though such confusion signals
the authenticity of an AR system, losing track of the real environment may not be productive for learning and could result in a threat to
students’ physical safety (Dunleavy et al., 2009).
