The evidence is mixed. Self and Ellison (1998) and Sindelar et al. (2003) demonstrated that in a full three-credit course on engineering ethics, the moral reasoning skills of students improve significantly. In a survey of students who had experienced sessions on responsible conduct of reserach, Plemmons et al. (2006) found that students felt they had acquired basic information, but had not improved skills or changed attitudes. These and other studies (Brown and Kalichman, 1998; Funk et al., 2007) have generally ignored differences in the methods of instruction, however.

The University of Massachusetts Amherst has initiated a digital ethics library
that it says "will also provide resources necessary to examine the advantages and disadvantages of using stand alone, off-the-shelf, online training packages and programs for teaching ethics. While these programs and materials can be efficient methods of teaching ethics, many experts question their effectiveness (See Kalichman 2005; NAE 2009; Schrag 2005; Sieber 2005; Smith-Doer, Journal of Empirical Research in Human Research, 2009, and others). The beta library will be a resource for institutions as they decide how their institutions will ensure appropriate ethics training for researchers."
