Acting ethically is a desirable and important outcome of student learning (American Psychological Association [APA], 2007; APA, Board of Educational Affairs, 2008). Because ethics permeates every topic in psychology, questions often arise regarding how to teach about the responsible conduct of research. In this chapter, we present a developmentally appropriate model that ensures "every psychology student is (or should be) presented with a range of ethical considerations as part of his or her undergraduate education" (Landrum et al., 2010, p. 158). Our "scope and sequence" agenda assumes that teaching ethically requires instructors to learn and teach ethics throughout their careers.Our suggestions for teaching about research ethics across the undergraduate curriculum derive from several sources. The APA (2007) student learning outcomes include objectives specific to teaching ethics. Additional resources include the developmentally coherent curriculum (APA, Board of Educational Affairs, 2008), discussions of ethical acculturation (e.g., Handelsman, Gottlieb, & Knapp, 2005), and guidelines for conducting ethical research (e.g., Aguinis & Henle, 2002;Kimmel, 2007). Throughout this chapter, we describe how teaching about research ethics can be systematically developed as students progress through the major.
