Educational materials are presented in the format of games such as role-playing where participants progress through game storylines within a game environment. Each game participant is assigned a game character having attributes that can be modified as the character progresses through the game storylines. The character encounters challenges and participates in game actions that require the participant to answer questions corresponding to educational materials that are sometimes contextually unrelated to the game storylines. The character also passes through portals to different worlds that are thematically related to different learning materials and where different learning experiences and testing occurs.
