Included are useful examples of programs focusing on issues of content and process in science teaching. The authors present day-in-a-life vignettes, along with a suggested reading list, to help familiarize scientists with the professional lives of K-12 science teachers. The book also offers scientists suggestions on how to take first steps toward involvement, how to identify programs that have been determined effective by teachers, and how to become involved in system-wide programs. Discussions on ways of working with teachers on program design, program evaluation, and funding sources are included.Accessible and practical, this book will be a welcome resource for university, institutional, and corporate scientists; teachers; teacher educators; organizations; administrators; and parents.
