This edited book aims to provide a global perspective on socioscientific issues (SSI), responsible citizenship and the relevance of science, with an emphasis on science teacher education. The volume, with more than twenty-five contributors from Africa, North and South America, Asia, Australasia and Europe, focuses on examples from in- and pre-service teacher training. The contributors expand on issues related to teachers' beliefs about teaching SSI, teachers' challenges when designing and implementing SSI-related activities, the role of professional development, both in pre- and in-service teacher training, in promoting SSI, the role of the nature of science when teaching SSI, promoting scientific practices through SSI in pre-service teaching, and the role of indigenous knowledge in SSI teaching. Finally, the book discusses new perspectives for addressing SSI in teacher education through the lens of relevance and responsible citizenship.
