This book is a toolkit for youth and young adult librarians-school and public-who wish to incorporate science, technology, engineering, art, and math (STEAM) into their programs and collections but aren't sure where to begin. Most educators are well aware of the reasons for emphasizing STEAM-topics that fall within the broad headings of science, technology, engineering, arts, and mathematics-in the curriculum, regardless of grade level. But how do librarians who work with 'tweens in middle school, high school, and public libraries-fit into the picture and play their roles to underscore their relevance in making STEAM initiatives successful? This book answers those key questions, providing program guidelines and resources for each of the STEAM areas. Readers will learn how to collaborate in STEAM efforts by providing information on resources, activities, standards, conferences, museums, programs, and professional organizations. Emphasis is placed on encouraging girls and minorities to take part in and get excited about STEAM. In addition, the book examines how makerspaces can enhance this initiative; how to connect your programs to educational standards; where to find funding; how to effectively promote your resources and programs, including how school and public librarians can collaborate to maximize their efforts; how to find and provide professional development; and how to evaluate your program to make further improvements and boost effectiveness. Whether you are on the cusp of launching a STEAM initiative, or looking for ways to grow and enhance your program, this book will be an invaluable resource.
