This Forum paper explores how Matthew Gaydos and Kurt Squire in their manuscript, "CITIZEN SCIENCE: Role Playing Games for Scientific Citizenship," represent issues of games literacy and science literacy. What is the meaning of expertise in the context of games-based learning? An examination of the studies presented suggests that games, like other ways of teaching, have both strengths and limitations, and that the exploration of games for science learning should reflect these considerations as well as the context of goals for science learning.
