Purpose: This study aims to understand the practices and perceptions of education for sustainable development (ESD) in the university classrooms of Malaysia, exploring how holistic, pluralistic and action-oriented approaches to ESD were linked to their knowingness, attitudes and behavior regarding sustainability. Design/methodology/approach: The perceptions of 2,678 students and 1,013 teachers from a range of undergraduate and postgraduate courses at four Malaysian universities were surveyed. Their views of ESD and sustainability consciousness (SC) were recorded on five-point Likert-type scales, and the resulting data was investigated using descriptive and analytical statistics. Findings: Holistic, pluralistic and action-oriented approaches to ESD teaching and learning were widespread in Malaysian universities, with significant associations found between ESD approaches and SC. While all three approaches enhanced each aspect of SC, the results indicated the need to develop action-oriented approaches more fully. Originality/value: This research underlines the importance of sustainability education in the context of higher education. It provides empirical evidence for developing action-oriented approaches to ESD and confirms the utility of holistic content and pluralistic pedagogy to the teaching and learning of sustainability.
