Many science education programs have recently been developed to increase girls' participation in science, however, few formal evaluations of these types of programs have been reported. The present research evaluated fifth grade girls' perceptions of a 1-day science education program. Students attended workshops describing different science fields. Study 1 revealed that attending the workshops increased students' interest in the specific field covered in the workshop. However, even after attending the workshops, students did not believe women typically entered those various fields. A second year evaluation revealed that most students agreed they had learned about individual tasks that scientists do in the various fields. However, significantly fewer believed they learned about educational requirements, problems women might face in the field, or how science can be used to help people. Results are discussed in terms of potential factors that workshop presenters might want to consider in future programs.
