This book is part I of a two-volume set that offers a comprehensive and interdisciplinary approach of Ethics in Science Education, including contributions from leading authors across various countries and cultural contexts. Through theoretical reflections and empirical studies, the chapters approach topics such as the anthropocene, climate and biodiversity crisis, ecopedagogy, virtues, and animal ethics. The common thread to all chapters is their attempt to answer the following question: How can ethical development within science education lead to personal and socioenvironmental transformations? By emphasizing the importance of ethics and the cultivation of ethical virtues in the field of science education, this book aims to inspire anyone interested in the adoption of a value-ethical-driven approach to socioenvironmental action, fostering more just and sustainable societies. It serves as a vital resource for anyone engaged in the quest for solutions to today’s pressing socioenvironmental challenges, especially science education researchers, science teachers, and activists.
