For many science teachers the integration of technology and engineering into the science curriculum will mean a new way of teaching, new concepts and skills for their students to learn, and new assessments that will measure their students’ progress and their own capabilities as teachers. The source of this concern is a publication by the National Research Council of a new blueprint for science education standards, appropriately titled A Framework for K-12 Science Education: Practices, Core Ideas and Crosscutting Concepts (NRC 2012). The Framework is currently severing as the blueprint for Next Generation Science Standards, aimed at replacing the current patchwork of state science standards with a common core, as has already been done in mathematics and English Language Arts. Since these documents raise engineering design to the same level as science inquiry there is no question that science teachers will be required to teach technology and engineering alongside science. This book is intended to help high school teachers by assembling, under a single cover, a collection of curriculum materials for integrating technology and engineering into science classes, and that are appropriate for different levels of the high school spectrum. All of the materials in this book have been under development for several years, tested by teachers and their students from a wide range of communities, and revised based on feedback. In many cases they are also supported by research studies of effectiveness. Each chapter describes one set of instructional materials, modules and text books for the high school level. Chapter authors have been asked to illustrate, as vividly as possible, what their curriculum looks like in the classroom, what learning goals it is intended to accomplish, and how it will help high school teachers address the Next Generation Science Standards. Also included is a helpful table, which lists each of the curriculum materials included in the book and grade level for which it is intended. Readers who are already familiar with the Framework and Next Generation Science Standards, and are mostly concerned with choosing curricula for a given grade or grade span can use the table to find the chapters that are most relevant to their needs. Readers who would like to know how technology and engineering are being integrated in the new standards—and why it will make a difference this time around—will find answers to these questions in the remainder of the introduction.
