Chapters 4–7 contain sections written by individual secondary math and science teachers (grades 6-12) who focus on different aspects of implementing design challenge units. In this chapter, the three teachers detail the teaching strategies they used. The chapter shows how the teachers introduced the engineering design process (EDP) and then guided students to understand what was expected of them as learners. Each teacher describes how the EDP engaged the students in the content and resulted in high student interest and increased learning. The important “takeaways” from this chapter are included. A list of materials, teacher background information, references, resources, assessments, and standards are provided. This book selection also includes the Table of Contents, Acknowledgments, Preface, About the Editors and Contributors, Appendix, and Index.
