Online gaming is becoming increasingly social and interconnected. Millions of players learn from each other in game-related communities on platforms like Reddit and Twitch.tv. However, few studies have been conducted to examine socially constructed learning in such environments. The purpose of this study was to explore learning in game-related communities using the Game Community of Inquiry Scale (GCoIS). GCoIS is a validated instrument inspired by the community of inquiry framework and developed for measuring constructed learning in these outlets. Over 1000 participants completed an online questionnaire that included the GCoIS and additional variables (e.g. demographics, gaming habits, and gaming metacognition) for measuring possible associations. Results pointed to gender, age, online participation, and metacognition about gaming as significant predictors of GCoIS. Findings suggest that gaming communities can serve as opportunities for meaningful learning when novice members are welcomed and assisted by experts and support is given to older and female gamers.
