Today, the documentation of children's education and development is an important part of educational work in early childhood education. This book systematises the topic of pedagogical documentation based on current empirical research. The book analyses different pedagogical reasons for documentation and then presents and discusses different procedures of pedagogical documentation in theory and empirical practice: Portfolio, Learning Stories, pedagogical documentation in the room, project documentation and digital pedagogical documentation. Pedagogical documentation is discussed in the tension between a social constructivist understanding of education on the one hand and a diagnostic logic of fostering on the other. The book is intended as a part of pedagogically oriented childhood research, which also wants to contribute to the reflection and improvement of pedagogical practice.
