Service learning refers to a form of experiential education that emphasizes for students the importance of accomplishing tasks that meet the needs of others. This paper describes the Service Learning Projects developed by the University of Iowa's Women in Science and Engineering (WISE) program. The purpose of the program is to design, implement, evaluate, and disseminate a model program for helping educators in extracurricular settings present science activities that will interest and challenge elementary and secondary school girls. The projects aim at increasing the awareness of gender issues in science, engineering, and mathematics; promoting gender-equitable teaching in science at all levels; placing science education in the context of the community; extending the scientific and technical resources of the university into the community; and increasing the visibility of female scientists and engineers.
