Who learns more: the impact of dual-player and single-player modes in a serious game on dental students' factual knowledge.

Background: The use of serious games in medical education provides a bridge between rapidly developing technology and traditional health-care teaching. Building on a promising web-based serious game for reviewing and acquiring factual knowledge in dental education, the present study investigated the benefits of a dual-player mode and various game options for enhancing knowledge gain and study motivation.

Methods: Before the intervention, students' dental knowledge and game experience were assessed using a pre-knowledge test and questionnaire-based self-assessment.
