Educational outcomes related to sustainability often include affective attributes such as values, attitudes and behaviours. Educators in higher education who attempt to research, monitor, assess or evaluate learning of affective attributes can face a bewildering array of methodologies and approaches and a research literature that spans several fields of enquiry. This article provides an overview of affective learning in the broad area of education for sustainable development, guidance for university teachers and researchers contemplating measuring affective attributes and a frame-work of affective attribute measurement based on the Krathwohl et al. (1964) taxonomy. (Contains 2 tables.)
