This introduction explains the main purpose of this book which is mainly to share knowledge and ideas about science education and STEM education. The book is intended to be an international book as it brings experiences and thoughts from around the globe. The authors of the chapters have brought to our attention topics related to issues found pressing in their own contexts. This book provides theoretical frameworks for researching and educating about science education and how it is positioned in the context of STEM education and vice versa. It came to the attention of the editors that a book is needed that provides a broad international perspective to implement STEM (science, technology, engineering, and mathematics) practices especially as despite the various funds for STEM education there has been slow progress ().
