Project Overview • Meet the increasing need to integrate instruction of microethical issues with instruction of macroethical issues: • “Microethics” = moral dilemmas & issues confronting individual researchers or practitioners • “Macroethics” = moral dilemmas & issues collectively confronting the scientific enterprise or engineering profession • 5 Project Goals: • Formulate educational outcomes for the integration of micro- and macroethicsin graduate science and engineering education • Develop and pilot different models for teaching micro- and macroethics to graduate students in science and engineering • Assess the comparative effectiveness of the instructional models • Facilitate adoption of the instructional models and assessment methods at other academic institutions • Provide for widespread dissemination of course materials and assessment results in the engineering, science, and ethics education communities.
Instructional Models • Stand-alone course (Science Policy for Scientists and Engineers-1 credit) • Technical course with embedded ethics content (Fundamentals of Biological Design) • Online/Classroom hybrid (Introduction to RCR in the Life Sciences – 1 credit) • Lab group engagement
Participants • Fall 2009 - Spring 2011 (Total N = 81) • Embedded Model (N = 21) • Stand-Alone Model (N = 14) • Hybrid Model (N = 20) • Lab Model (N = 2; excluded from analysis) • Control Group (N = 26) • Student Status: • Undergraduates 5 • Transitional 5 • Masters 20 • PhD 50 • Mean Age = 24.23 • Males = 55; Females = 26
Participants (cont’d.) • Academic Program: • Biodesign 21 • Engineering 30 • Chem/BioChem 9 • Biology 12 • Other 5 • Missing 4 • Previous Ethics Instruction: Yes = 36 • Previous S. R. Instruction: Yes = 22 • First Language: • English 54 • Chinese 10 • Indian Language 8 • Spanish 2 • Korean 2 • Other 5 • Ethnicity/Race: • White 41 • Asian 28 • Hispanic 6 • African American 3 • Other 3
Procedures • Nonequivalent Control-Group Quasi-Experiment • Survey measures of 3 desired learning outcomes: • Increased knowledge of relevant standards • Increased ethical sensitivity • Improved ethical reasoning • Engineering & Sciences Issues Test (ESIT) – short • Study-Specific Measures: • Knowledge of Relevant Standards (T/F/don’t know) • Ethical Sensitivity (1-5 scale) • Student-Instructor Interaction: • Out-of-classroom communication • Classroom climate (supportive/defensive) • Instructor verbal aggressiveness • Instructor verbal assertiveness • Frequency of informal ethics conversations

Student-Instructor Interaction • Classroom dynamics similar across instructional models: • 1 group difference in interaction variables – verbal aggressiveness higher in Embedded than in Hybrid • All other interaction variables statistically the same across instructional groups • Out-of-class communication associations: • With posttest ethical sensitivity (r = -.35, p < ,01) • With posttest ethics discussions with lab directors (r = .34, p < .05) • Frequency of ethics conversations increased: • Significantly with peers • Not significantly with lab directors/PIs
Implications • All models were effective in increasing knowledge, sensitivity, and moral reasoning • Knowledge gains highest in Hybrid Group: Consistent with previous research showing combining instructional modes more effective than either mode on its own • Language differences point to caution when using survey instruments with non-native English speaking samples • Sex differences might be related to language differences • Out-of-classroom communication points to importance of informal conversations and spillover effect of mentoring relationships • Students benefitted from flexible, interdisciplinary team of dedicated educators. • Successful integrative ethics education depends on commitment & cooperation of academic departments.
