With the advancement of mobile technology and augmented reality (AR), the serious and abstract ethics theory in sports and recreation can be articulated to students in a relaxed but concrete format. The Trail of Integrity and Ethics -- Sports and Recreation (TIE-SR) was piloted for this purpose. Its content was designed specifically to cover key concepts in sports ethics such as "corruption" and "doping." Findings suggest that undergraduates who participated in this learning trail have a higher awareness of key concepts in sports ethics and were satisfied with the use of AR as a new way to complement sports ethics education.
