role of media characters in mathematical skill learning; very early learning from media; and the role of production features (e.g., action, sound effects, dialogue) as representational tools to help children think about and understand content. As media platforms have evolved and changed, she has grown with the times, examining diverse kinds of interfaces ranging from stories presented in television and film to computer, video, and virtual reality games, to apps on tablets and math games taught by intelligent agents. Policy Calvert has served on numerous advisory committees and made numerous media presentations to improve the quality of children's media, including a series of lectures for the U.S. State Department about creating quality educational media, which was hosted by the U.S. embassy in Macedonia. In the educational media area, she presented testimony before the Senate Committee on Commerce, Science, and Transportation about the impact and future of the Children's Television Act, which requires broadcasters to provide educational and informational programming for children. She also served on two committees for the National Academies, one on youth, pornography, and the Internet, and the second on the role of food marketing in the pediatric obesity crisis, as well as on an American Psychological Task Force to examine the impact of violent video games on youth aggression.
