This must-have guide to developing a teaching portfolio walks preservice and practicing teachers alike through different types of portfolios, clearly explaining their uses and purposes, and how each of these portfolio types is developed. Both novice and masters teachers will benefit from the practical, hands-on, and straightforward nature of this guide at each new step of their teaching career.   With a focus on using portfolios to show one's work throughout a professional teaching career, this compact, easy-to-read volume provides both prospective and current teachers the foundation as well as the specifics to be successful in their portfolio building endeavors. A two-part organization explores portfolio building for students and novice teachers who have yet to engage in this activity and then offers a menu of topics from which more experienced educators can choose to inform their creation of targeted, results-oriented portfolios for a variety of situations.   The newly revised third edition of this text includes case studies that follow real teachers through their careers as well as a wealth of new digital and hardcopy portfolio examples.
