This book explores the complex nexus of discourses, principles and practices within which educators mobilise school-based health education. Through an interrogation of the ideas informing particular models and approaches to health education, the authors provide critical insights into the principles and practices underpinning approaches to health education policy, curriculum, pedagogy and assessment. Drawing on extensive literature and research, the book explores and considers what health education can and should do. Chapters examine the extent to which health education, past and present, has attended to the needs and interests of young people in school environments, as well as assess common pedagogical approaches and whether the outcomes tally with expectations. By considering the problems in teaching health education, curriculum making, health education pedagogies and porous classrooms, the book offers a knowledge base from which educators can consider how theories and models can sit together to shape curriculum and influence practice. School Health Education in Changing Times will be of key interest to postgraduate students, researchers and academics in the field of health education. It will also be a valuable resource for teacher educators, current teachers, and those on professional development courses who want to navigate the moral minefield surrounding health education.
