Abstract: Most outcomes assessment in higher education has focused on content knowledge or skills development; however, attitudinal change is also a legitimate focus of assessment. We use the New Ecological Paradigm (NEP) to test whether courses designed to meet the same university environmental literacy requirement changed student environmental attitudes, and whether these changes resulted from instructor and/or course-content effects. We found student environmental attitudes did change significantly but in different directions depending upon who taught the course. The ability to measure such changes adds to the discussion in the environmental education community on the desired nature of attitudinal change and of the responsibilities of higher education instructors.
