Museum provide an ideal inquiry learning environment with fruitful learning resources,such as museum exhibits and learning materials.In recent years,many studies have been conducted to enhance childrens interactive experiences and learning motivations in museums by taking advantage of emerging digital technologies.However,the neglecting influences of museum contexts negatively affect children learning with digital applications in museums.Besides,cognitive overload significantly influenced children learning with digital applications in museums.To this end,this study develops a real-world adventure game-based learning environment with a mobile system named CoboFun to encourage children interacting between museums virtual and physical contexts through various types of game-based problem-solving activities.Childrens learning experiences,i.e.,the playfulness,physical interactions,social interactions,motivations,and mental workload were examined to evaluate the CoboFun design.Moreover,the relationships between childrens experiences and mental workload were evaluated.The results showed CoboFun can support children interacting between virtual and physical environments.Moreover,there is significant relationships between childrens experiences and mental workload.
