This paper describes the early childhood teacher training program and the role of the Project Approach in the final practicum for student teachers in the Lisbon School of Education, Portugal. Student teachers, cooperating teachers, university supervisors, and instructors of teaching methods worked together to involve young children in interesting projects. This cooperation provided an opportunity for innovation and experimentation and, especially, a context for teacher educators to deepen their understanding of their roles and to improve their teaching strategies. As a consequence, the final practicum became central to the teacher education program. The article concludes with seven lessons learned as a result of this process.
