This chapter shares a brief history and current overview of HRE today, with snapshots of HRE in practice in various contexts across the globe. First explaining HRE through definitions and models of teaching and learning, it then examines HRE with a critical eye. Following this, in connecting theory to practice, the chapter offers examples of HRE in formal, non-formal, and professional settings, as a means of instilling values, sharing knowledge, and training in skills to advocate for human rights.
