Career choice is a process, not an event. Interest in science is a preliminary step toward and prerequisite for a career in science. Once interest in science is established, training and education can then provide the critical links between labor-force needs and supply. Unfortunately, interest in science is frequently derailed by the prevalence of persistent and tenacious negative stereotypes (Steinke et al. 2007). In this article, the author discusses these stereotypes, and then describes an innovative twist on a classic activity that can be used with middle school, high school, and college students to challenge existing stereotypes by activating and confronting preconceived images of scientists.
