A famous stage actress was once asked if she had ever suffered from stage-fright, and if so how she had gotten over it. She laughed at the interviewer’s naive assumption that, since she was an accomplished actress now, she must not feel that kind of anxiety. She assured him that she had always had stage fright, and that she had never gotten over it.

CME Project About the Program. The CME Project, developed by EDC’s Center for Mathematics Education and published by Pearson, is a coherent, four-year, NSF-funded high school mathematics program designed around how knowledge is organized and generated within mathematics: the themes of algebra, geometry, and analysis. The CME Project sees these branches of mathematics not only as compartments for certain kinds of results, but also as descriptors for methods and approaches—the habits of mind that determine how knowledge is organized and generated within mathematics itself.
