In her second paper, "Electronic Play Worlds," Kafai takes a close look at the video game artifacts designed by children to address the issue of gender differences. In studying the popularity of video games among children, many researchers have focused on explaining why boys in particular love playing these games. In this paper, Kafai uses the process of game design to elicit children's ideas and interests in video games. The students' choices are analyzed and discussed in regard to their game themes, worlds, characters, interactions, feedback, and narrative. The design of the games reveal clear gender-related differences and provide strong support for design activities as a way for children to express their personal preferences. Conclusions address the potential of game-making environments.
