AbstractThe thesis is based on implementing a child-centered design approach in the creation of a game
authoring tool for children to be used in the classroom as one of their learning tools. Indeed,
research in designing such educational software is primarily focused on the learning outcomes, but
not on the usability. However, the usability of such software for children is a prerequisite for
any learning to be useful and significant. The thesis purposes with a belief that substantial
improvements can be made by paying careful attention to usability during the design of the game
authoring tool. Unlike the related approaches, the scope of research focuses on the game authoring
tool which emphasizes on the design of the game authoring tool and concentrates on the flexibility
of the interaction and construction activity in making games. This research methods started by
investigating works from other researchers including comparing the .....
