This LTP equips teachers, student teachers and teacher educators with knowledge, skills and perspectives and ‘hands-on’ experience to strengthen education for sustainability in their contexts of practice, through four units with distinct and complementary emphases. Unit 1 provides a foundation in the concept of sustainability, and opportunity for creative and critical engagement in relation to real-world challenges and responses. In unit 2, participants envision ‘a sustainable Europe’, learn about European measures for sustainability, and how they and their students can be directly involved. Unit 3, focuses on the relationship between education and sustainability, provides an overview of relevant topics, perspectives, pedagogical approaches, and whole-school approaches, and guides participants to plan a BNE intervention. Unit 4 focuses on linguistic and cultural diversity as central to education for sustainability. Participants explore ideas about language and culture and how to recognise and respond to linguistic and cultural diversity across curriculum subjects and the whole school. All units reflect a view of teachers as reflective practitioners, whose experience and expertise is the basis for professional learning. In each unit, participants engage with their current beliefs, values and practices in relation to international policy and research-based insights and experience participatory and action-oriented methods, such as participatory system mapping, Theory of Change and visual methods for critical and collaborative thinking. Through the 4 units, participants are guided to identify strengths and areas for development in their context of practice and to plan, do and review action for improvement. Most of the activities in these units are directly adaptable for use with secondary school students.
