Environmental awareness and ethical moral reasoning are important aspects of the engineering profession. Yet, engineering programmes have been struggling to teach these topics and measure the effectiveness of these educational interventions. In this study, we tested the effectiveness of two independent measures of environmental awareness and moral reasoning. We conducted pre-and post-test in two groups (experimental and control). Our sample was 84 students in the control group and 152 students in the experimental group. Data were collected with a survey. Results suggest the instruments were effective in measuring changes in scores, although they presented some limitations. Based on our results, we discuss implications for education practice and policy.
