First published in 1985. In the mid-seventies, there was growing concern that early decisions not to study mathematics in high school might be limiting the occupational options available to women. As part of a larger program on career development, the Career Awareness Division of the Education and Work Group, then one of the major organizational units of the National Institute of Education (NIE), initiated a special research grants program on women and mathematics. Research information that would sort out the competing explanations for women's lower rate of participation seemed a useful contribution to debates about possible remedial actions. Should there be, for example, widespread development and implementation of programs designed to reduce mathematics anxiety? This volume represents the culmination of a research program with many contributions.
