Portfolio work is an excellent way to strengthen students' sense of responsibility for their learning process and relieves you as a teacher, as you are not constantly in the spotlight of the classroom. The two experienced teacher trainers, Bettina Geiger and Gabriele Wisor, explain in this compact guide what portfolio work actually is and answer fundamental questions such as: What is my role as a teacher during the work phase? How do I check if the students are really using their working time effectively? And: How much time should I allocate for correction and assessment? The editable templates and checklists included on the accompanying CD will help you adapt the concept to your own needs without significant additional effort. To ensure everything runs smoothly, the authors describe the most important pitfalls.
