Problem solving is a key element of computer science. It is also a research topic within computer science education examining topics like processes, tasks and attitudes with regard to computer scientific approaches and contents. Our computer science escape game “Room-X” offers learners an insight into computer science and enables them to practice problem solving in an attractive and motivating environment. From a research perspective, Room-X allows us to observe learners of computer science while solving problems and to analyze their strategies involved. Video analyses are used to analyze behavioral patterns and to draw conclusions in order to promote problem solving skills in computer science and to further develop Room-X.
