Transformational education for sustainability calls for a shift away from just focusing on the acquisition of knowledge and skills to an a more holistic emphasis on values, attitudes, and behaviours. This requires constructively aligned teaching, learning and assessment activities designed to meet key education for sustainability competencies and learning outcomes. Teaching and assessment practices can provide opportunities for learning experiences that will embrace alternative viewpoints, critical reflection, and real-world challenges. This workshop will explore some approaches within a framework of Assessment OF, FOR and AS Learning for Sustainability.
