Two children identify a problem within their community and go through the process of gathering research, joining organizations, using technology and creating a solution in order to make the world a better place. This A-Z guide provides learning experiences that help students gain the skills and knowledge to take sustained and meaningful action. It includes photocopiable extension activities and active links to free online resources such as: a complementary curriculum document, videos, eBooks, as well as a community of student change agents. These resources enable teachers to implement a comprehensive program that further explore the concepts within this book. Both book and resources were created as a result of a teacher-initiated action research project published in the IB Journal of Teaching Practice.
