Over the course of the early 21st century, STEM has enjoyed a bandwagon effect as the brand strengthens. In this chapter, purists and pioneers have put structures in place to establish a certain standard that upholds important labels such as STEM teacher, STEM classroom, and STEM school. What brands a teacher, a classroom, or a school as “STEM”? That is the value of standardized rubrics and systems of recognition to discern and honor best practices in preparing educators. These structures, standards, and their effect are explored. Teacher background information and references are included. This book selection also includes the Table of Contents, About This Book, Acknowledgments, Epilogue, and Index.
