This text contains 24 Project-Based Learning (PBL) lessons written by high school teachers (adaptable for middle school) that include lesson appropriate for all subjects. All the PBL lessons in the book were used in urban high-school classrooms. The lessons were developed over a three-year period while working with the Aggie Science, Technology, Engineering, and Mathematics (STEM) Center. The PBL lessons are mostly extended activities but adaptable to various situations and are interdisciplinary covering science, mathematics, technology, engineering, social studies, and language arts objectives. Each chapter contains the information necessary to implement each lesson, including handouts, scenario descriptions, rubrics for scoring, and all the elements likely to ensure successful implementation. All lessons include both formative and summative assessment tools as well as a separate section on assessment with sample multiple-choice items matched to high-stakes assessments common in most states. This practical book is the perfect companion to the handbook for learning about implementing PBLs: Project-based Learning: An Integrated Science, Technology, Engineering, and Mathematics (STEM) Approach.
