In 100 years as a nation-state, Finland has become the world's benchmark for quality in school education. Despite the fact that Finland is consistently top ranked by international performance measures, the country continues to rapidly change their curriculum and educational policies. This book documents these main curricula changes, telling the story of the future of school education in Finland as it begins to develop in 2016, 2017, and 2018 onwards. Drawing from 14 original case studies, the book presents the stories of 14 principals and 29 teachers with a systematic and methodological uniformity. Intertwining the Finnish example with a greater narrative about how universities are changing their teacher education to face the complex challenges of education in the 21st century, this book documents cutting-edge advancement in the field of international school education.
