We suggest that students would profit immensely from learning why (otherwise)well-intentioned people fail to live up to their own moral commitments and/or the ethicalrequirements of their professions. And after teaching students about this last, we believe studentsshould be provided a set of tools, an ethical toolbox if you will, they can use to decrease thelikelihood that they will make ethical errors in the future. Most (perhaps all) professional ethicsclasses and textbooks neglect to provide students with these tools.1# (Note: We do not claim thatlearning ethical theory is unnecessary or ought to be eliminated.

Inorder to best leverage available resources for the program, a complete redesign of thecombinations of course offerings, the physical resources, and the human resources wasundertaken. Although local industry had a vested interest, and supported the redesign, thisrestructuring project was initiated and completed by the program’s faculty.Course Offerings (within the major)Table 1 lists the major course offerings by semester and by lab as they were originally offered.This is a pretty traditional arrangement, and very similar to other programs in the system.Table 1.

Each part of the programwas designed to support one or more of the goals of the ESA which are 1) building academic selfefficacy, 2) creating a sense of community and belonging, 3) balancing academic, social life andself, and ultimately 4) retention. There was a significant increase in the scores on the firstphysics exam for the Backstage Bucknell ESA 2016 participants as compared to the previousESA 2015 class. Given that the student selection process and other programming for the ESAstudents has been the same this academic year as in the past, it is likely that these increases inperformance can be attributed to the Backstage Bucknell programming.BackgroundThe ESA is an academic success program
